-## 5. Game mechanics 
+## 5. Game mechanics - offensive weapons
 
-And here's a rundown of the description of how each weapon works, scoring rules, etc:
+### Energy of tanks.
+- At the beginning of each round, each tank has 99 ash units of energy.
+- Tanks' energy is depleted in 3 ways:
+    * one unit after each shot is fired
+    * while falling (one pixel down 2 units).
+    * when a projectile hits the tank or next to it - and here the amount of energy subtracted depends on the distance from the center of the explosion and the type/power of the projectile.
 
-### First, what we know about tank energy
-- Tanks have energy (and Ogres have layers - like an onion) - 99 units at the start of a round.
-- Energy of tanks is depleted in 3 ways:
-    1. one unit after firing each shot,
-    2. while falling (one pixel down takes 2 units of energy),
-    3. when a projectile hits a tank or its proximity. The amount of energy subtracted depends on the distance from the center of the explosion and the type/power of the projectile.
+### How energy subtraction works (and earning money!).
+After each round the amount of money gained/lost is calculated this is done on the basis of two variables accumulated by each tank during the round. These variables are:
 
-### How energy subtraction works (and makes money!)
+`gain` - energy "captured" from tanks hit (also if you hit yourself :) and here's the catch, if you have very little energy left it can be profitable to hit yourself with a powerful weapon!
 
-After each round, the amount of money gained/lost is calculated. This is done on the basis of two variables accumulated by each tank during the round. These variables are:
+`lose` - energy lost due to explosion/fall (and here it is important to count the total loss of energy even if the tank has less at the moment of hit).
 
-`gain` - energy "captured" from hit tanks (also when you hit yourself :) and here's the catch, if you have very little energy left it may be profitable to hit yourself with a powerful weapon!
-
-`lose` - energy lost due to explosion/fall (important - the total potential loss of energy is taken into account even if the tank has less at the time of the hit).
-
-In addition, the tank that won the round has a `gain` parameter (captured energy from tanks hit) increased by the energy remaining at the end of the round (because it did not die and should have it - although the survival of the fittest is not guaranteed :) )
+In addition, the tank that won the round has a parameter gain (captured from hit tanks energy) increased by the remaining energy at the end of the round (because it did not die and should have it - although it also happens otherwise :) )
 
 Specifically:
 
 ### After each round:
-`money = money + (2 * (gain + energy))`
-`money = money - lose`
-`if money < 0 then money = 0`
+`money = money + (20 * (gain+energy))`.
 
-(at the start of each round `gain` and `lose` have a value of 0)
+`money = money - (10 * lose)`.
+
+`if money <0 then money=0`.
+
+(at the start of each round `gain` and `lose` have a value of 0).
 
 During a round, if another tank is hit as a result of a shot fired by a tank, the tank firing the shot "gets the energy" taken away from the hit tank.
+### tank taking a shot:
+`gain = gain + EnergyDecrease`.
+### tank hit:
+`lose = lose + EnergyDecrease`.
 
-### For tank firing a shot:
+Where `EnergyDecrease` is the loss of energy due to the hit.
 
-`gain = gain + EnergyDecrease`
+Of course, at the same time the hit tank loses the amount of energy stored in `EnergyDecrease`, except that here the loss cannot exceed the energy you have.
 
-### Tank being hit:
+## How a hit works.
 
-`lose = lose + EnergyDecrease`
-
-Where `EnergyDecrease` is the loss of energy due to a hit.
-
-Of course, at the same time, the hit tank loses the amount of energy stored in `EnergyDecrease`, except that here the loss can not exceed the energy held.
-
-Note that the screen representation of money has an extra 0 added at the end so you actually have 10 times more cash than the above calculation shows :)
-
-## How the hit works.
-
-Each weapon that results in an explosion has a radius of fire (`ExplosionRadius`).
+Each weapon that results in an explosion has its own blast radius.
 
 After the explosion, every tank in its range loses energy.
 
-The way it works is that the distance of the hit tank from the center of the explosion is calculated, the `ExplosionRadius` reduced by this distance is multiplied by 8 and the result is `EnergyDecrease`.
+It works in such a way that if the hit is exactly on the center point of the tank `EnergyDecrease` receives the maximum value for the weapon, and for each pixel of distance from the center of the tank this value is reduced by 8.
 
-That is, in the case of hitting a tank centrally:
-`EnergyDecrease = ExplosionRadius * 8`
-and with each pixel farther from the center, 8 fewer units are lost.
+For example, if a hit with the Baby Missile weapon hits the center of the tank perfectly, it will lose exactly 88 units of energy (plus what it loses falling after the explosion).
+If you hit with the same weapon at a distance of 10 pixels from the center of the tank, the loss will be only 8 units.
 
-I don't know if it's understandable - I do understand it :)
+And here are the values of maximum energy loss for individual weapons. If a weapon explodes several times, each explosion is calculated independently (additional values in the table):
 
-For example, if a tank is hit centrally with a Baby Missile - it is subtracted 88 units of energy (11 * 8), which also means that when this missile hits at a distance of 12 pixels from the tank - it does not lose energy at all.
-
-And here are the `ExplosionRadius` values for each weapon:
-
-| Weapon | `ExplosionRadius` |

-| Roller | 21 |
-| Heavy Roller | 31 |

-| Ton of Dirt |  31 |
-| Liquid Dirt | 0 (maybe it's worth changing?) |
-| Dirt Charge | 0 (61 - as above) |
-| Laser | x 100 (but here it is also different - equally 100 only in the case of a direct hit, the `ExplosionRadius` variable is not used, so there is no multiplication by 8 - we simply subtract 100 units of energy - that is, the tank always dies).|

+## 6. And now for defensive weapons:
 
 * **White Flag** - causes the surrender of the player (can sometimes be useful in a hopeless situation). The advantage is that by surrendering you don't give a big point to your opponents and don't cause one of them to gain by killing us, you also limit the loss of your energy and also cash. An important note - this is the only defensive weapon that can be deactivated. All you have to do is re-enter inventory and once again select its activation.
 * **Battery** - when activated, it recharges the tank's energy to full (99 units) and at the same time is the only defensive weapon that does not deactivate other defensive weapons when used.
 * **Hovercraft** - a weapon that allows the tank to move. It has its own fuel supply in form of electric eels and in addition, it can be activated multiple times during the same turn, and after using it, you can activate another defensive weapon and fire a shot in the same turn. After using it, the tank rises above the mountains and using the cursor keys or a joystick you can move the tank to a new position. [SPACE] or the joystick button cause the tank to land in a new place. You can fly until the tank runs out of eels (presented on the status bar like the energy of a defensive weapon), if the eel fuel runs out the tank will fall down on its own. It is not possible to land on other tanks.
 * **Parachute** - does not protect against loss of energy due to a neighboring explosion, makes you not lose energy during ONE fall. After such a fall, it deactivates and a new parachute must be activated.
-* **Shield** - the simplest shield works exactly the opposite of **Parachute**, it does not protect against energy loss while falling, instead it protects against energy loss caused by ONE adjacent explosion. It protects once, no matter how strong the explosion is (whether it's just a "scratch" or a direct hit with a nuke), and deactivates immediately afterward.

It protects once, no matter how strong the explosion is (whether tis but a scratch or a direct hit with a nuke), and deactivates immediately afterward.
 * **Heavy Shield** - a shield with its own energy (at the start of 99 units), it works the same as **Shield** (does not protect against falling) with the exception that it has its own energy resource. When exploding, the energy of this shield is reduced first, and if it reaches 0, the shield deactivates and further reduces the tank's energy. Due to this action, a tank with this type of shield can be "killed" by undermining it, because falling reduces the energy of the tank and not the shield.
 * **Force Shield** - the strongest shield - works just like Heavy Shield only that it is combined with **Parachute**. What is important in this case, falling does not take energy away from the shield or the tank. It is only taken away by hits.
-* **Bouncy Castle** - a passive-aggressive weapon :) . It works as follows. In case of a direct hit on the tank (and cover), it causes the projectile to "bounce" in the opposite direction with the same force with which it was fired. In the absence of wind and a difference in level, the weapon then hits the tank that fired it. After such a bounce, it deactivates. As the weapon reacts in this way only to precise hits, it is also a shield that corresponds to the action of **Heavy Shield** and has 99 units at the start (you will probably have to rethink this value and give a smaller one here).

 * **Mag Deflector** - the second passive-aggressive weapon :) . In case of a direct hit on a tank (and shield), it causes the hit point to move randomly to the left or right side of the protected tank, but not very far, so you can get "shrapnel" with stronger weapons. As in the case of **Bouncy Castle**, it is also a shield that corresponds to the action of **Heavy Shield** and has 99 units at the start (probably here we will have also to rethink this value and give a smaller one).
 * **Nuclear Winter** - adds nothing, takes nothing away :) - in fact, it is not so much a defensive weapon as a double-edged one. It floods the area with "radioactive" fallout, which is ordinary soil. If you do not have at hand any weapon that digs up the terrain, and for that a shield (preferably disposable), then after such "fallout" you will have to shoot yourself - because being underground is otherwise impossible. Alternatively, **White Flag** always remains.
 * **Long Schlong** - a special weapon :) - Costs a lot, doesn't really help with anything (except possibly digging yourself out but only when slightly buried but it has a cool name and looks cool :) - It can be activated independently of other defensive weapons and remains active until the end of the round (it cannot be deactivated).

+
+The game has 8 difficulty levels of computer-controlled opponents. Or actually 7 different ones and one "surprise". Each has its own way of buying defensive and offensive weapons and a different method of target selection and targeting itself, as well as weapon selection. They are arranged in the list according to increasing "skills":
+
+* **Moron** - the dumbest of opponents (which does not mean the safest). Shoots completely at random using only one weapon - **Baby Missile**. He doesn't buy anything and doesn't know how to use defensive weapons.
+
+* **Shooter** - This opponent does not shoot blindly. He chooses one direction for himself. Based on his own position - he shoots in the direction from which there is more space assuming that this is where the other tanks are. He starts firing from a high angle and shot after shot changes this angle to a lower and lower angle trying to fire the entire area on the chosen side. He always fires with the best weapon he has (the highest on the list of weapons he has - that is, not necessarily the best). He does not use defensive weapons even though he buys them! At the beginning of the round, he makes 1 attempt to buy defensive weapons (only from the **Battery** - **Strong Parachute** range) and 4 offensive weapons (from the **Missile** - **Heavy Roller** range).
+
+* **Poolshark** - When attacking, he sets the nearest tank as his target, then selects the angle of the shot, and tries to select its strength by drawing it from the selected range. He always shoots with the best weapon he has. He uses defensive weapons. With a probability of 1:3, he activates the best defensive weapon he owns (the highest on the list of weapons he owns - that is, not necessarily the best) before firing. If his energy level drops below 30 units - he uses **Battery** (of course, if he bought it before), if the energy drops below 5 and he has no **Battery** he surrenders - **White Flag**. At the beginning of the round he makes 1 attemp to buy defensive weapons and 6 offensive weapons.
+
+** **Tosser** - When attacking, he acts exactly like **Poolshark** however, he may have a "better" weapon inventory due to a different purchase tactic. He always activates the best defensive weapon he has before shooting. And just like **Poolshark** he uses **Battery** and **White Flag**. At the beginning of the round, he assesses how much money he has and depending on that, he makes (money/5100) attempts to buy defensive weapons and then checks again how much money he has left and makes (money/1250) attempts to buy offensive weapons.
+
+** **Chooser** - Takes as a target the weakest opponent (with the least amount of energy) and aims very precisely, but before the shot the energy of the shot is modified by the parameter of luck :) , that is, despite the precise aiming it does not always hit. He shoots with the best weapon he has unless the target is close. Then he changes his weapon to **Baby Missile** to avoid hitting himself. He always activates the best defensive weapon he has before shooting and, like **Poolshark**, uses **Battery** and **White Flag**. He purchases just like **Tosser**.
+
+* **Spoiler** - He shoots exactly like **Chooser** except that he has more luck :) , which means that even if he doesn't hit the target of his choice, it can be a more precise shot than **Chooser**. He uses defensive weapons exactly like **Chooser**. At the beginning of the round, he assesses how much money he has and depending on that, he makes (money/5100) attempts to buy defensive weapons and then checks again how much money he has left and makes (money/320) attempts to buy offensive weapons. When buying defensive weapons, he buys only strong and precise weapons - that is, weapons that won't accidentally hurt him.
+
+** **Cyborg** - Takes aim at the weakest opponent (with the least amount of energy) but prefers human-controlled opponents. Aims very accurately and in the vast majority of cases hits on the first shot. He fires the shot with the best weapon he has unless the target is close. Then he changes his weapon to **Baby Missile** to avoid hitting himself. He uses defensive weapons exactly like **Chooser**. He shops exactly like **Spoiler**.
+
+* **Unknown** - Before firing each shot, he randomly chooses a course of action from **Poolshark** to **Cyborg** and applies his tactics. However, the tactics of weapon purchases are always identical to **Tosser**.
+
+Trying to buy a weapon (offensive or defensive) is as follows:
+First, one of the weapons is drawn (among all possible offensive or defensive weapons). Then a check is performed to see if the drawn weapon is in the list of weapons possible for purchase by the tank. If not, no weapon is bought in this trial, and if so, its price is checked. If the tank has that much money, the weapon is bought, otherwise the trial ends without making a purchase.

 Po eksplozji każdy czołg w jej zasięgu traci energię.
 
-Działa to tak, że obliczana jest odległość trafianego czołgu od centrum eksplozji, zmniejszony o tę odległość ExplosionRadius jest mnożony przez 8 i w wyniku otrzymujemy `EnergyDecrease`.
+Działa to tak, że jeśli trafienie jst dokładnie w centralny punkt czołgu `EnergyDecrease` otrzymuje maksymalną wartość dla danej broni, a za każdym pikselem odległości od centrum czołgu wartość ta jest zmniejszana o 8.
 
-Czyli w przypadku trafienia centralnie w czołg:
-`EnergyDecrease = ExplosionRadius * 8`

-Nie wiem czy to zrozumiałe - ja rozumiem :)

-Przykładowo, jeśli czołg zostanie trafiony centralnie przy pomocy Baby Missile - odejmowane jest mu 88 jednostek energii (11 * 8), co także oznacza, że przy trafieniu tym pociskiem w odległości 12 pikseli od czołgu - nie traci on energii wcale.

+## 8. Poziomy trudności przeciwników sterowanych przez komputer:
+
+Gra posiada 8 poziomów trudności przeciwników sterowanych przez komputer. A właściwie 7 różnych i jeden "niespodziankę". Każdy z nich ma swój sposób kupowania broni defensywnych i ofensywnych oraz inną metodę wyboru celu i samego celowania, oraz wyboru broni. Ułożone są one na liście według wzrastających "umiejętności":
+
+* **Moron** - najgłupszy z przeciwników (co nie znaczy że najbezpieczniejszy). Strzela całkowicie przypadkowo używając wyłącznie jednej broni - **Baby Missile**. Nie kupuje nic, nie umie stosować broni defensywnych.
+
+* **Shooter** - Ten przeciwnik nie strzela na oślep. Wybiera sobie jeden kierunek. Na podstawie własnej pozycji - strzela w stronę z której jest więcej przestrzeni zakładając, że to tam są inne czołgi. Ostrzeliwanie zaczyna od wysokiego kąta i strzał po strzale zmienia ten kąt na coraz niższy starając się ostrzelać cały obszar po wybranej stronie. Strzał oddaje zawsze najlepszą posiadaną bronią (najwyższą na liście posiadanych broni - czyli nie koniecznie najlepszą). Nie używa broni defensywnych mimo, że je kupuje! Na początku rundy podejmuje 1 próbę zakupu broni defensywnych (tylko z zakresu **Battery** - **Strong Parachute**) i 4 ofensywnych (z zakresu **Missile** - **Heavy Roller**).
+
+* **Poolshark** - Atakując wyznacza sobie za cel najbliższy czołg, następnie dobiera kąt strzału, a jego siłę stara się dobrać losując ją z wybranego przedziału. Strzał oddaje zawsze najlepszą posiadaną bronią. Używa broni defensywnych. Z prawdopodobieństwem 1:3 aktywuje przed oddaniem strzału najlepszą posiadaną broń defensywną (najwyższą na liście posiadanych broni - czyli nie koniecznie najlepszą). Jeżeli poziom jego energii spadnie poniżej 30 jednostek - używa **Battery** (oczywiście jeśli wcześniej ją kupił), jeżeli energia spadniej poniżej 5 i nie ma **Battery** poddaje się - **White Flag**. Na początku rundy podejmuje 1 próbę zakupu broni defensywnych i 6 ofensywnych.
+
+* **Tosser** - Atakując działa dokładnie tak jak **Poolshark** jednak może posiadać "lepszy" zasób broni dzięki innej taktyce zakupów. Zawsze przed strzałem aktywuje najlepszą posiadaną broń defensywną. i tak jak **Poolshark** stosuje **Battery** i **White Flag**. Na początku rundy ocenia ile ma pieniędzy i w zależności od tego podejmuje (pieniądze/5100) prób zakupu broni defensywnych a następnie jeszcze raz sprawdza ile pieniędzy mu zostało i podejmuje (pieniądze/1250) prób zakupu broni ofensywnych.
+
+* **Chooser** - Obiera sobie za cel najsłabszego przeciwnika (o najmniejszym zasobie energii) i celuje bardzo dokładnie, jednak przed samym strzałem energia strzału modyfikowana jest o parametr szczęścia :) , czyli mimo precyzyjnego wycelowania nie zawsze trafia. Strzał oddaje najlepszą posiadaną bronią chyba że cel jest blisko. Wtedy zmienia broń na **Baby Missile** by unikać trafienia samego siebie. Zawsze przed strzałem aktywuje najlepszą posiadaną broń defensywną i tak jak **Poolshark** stosuje **Battery** i **White Flag**. Zakupów dokonuje tak samo jak **Tosser**.
+
+* **Spoiler** - Strzela dokładnie tak jak **Chooser** tyle, że ma więcej szczęścia :) , co oznacza że nawet jeśli nie trafi w wybrany cel, to może być to strzał precyzyjniejszy niż **Chooser**. Broni defensywnych używa dokładnie tak jak **Chooser**. Na początku rundy ocenia ile ma pieniędzy i w zależności od tego podejmuje (pieniądze/5100) prób zakupu broni defensywnych a następnie jeszcze raz sprawdza ile pieniędzy mu zostało i podejmuje (pieniądze/320) prób zakupu broni ofensywnych. Przy zakupie broni defensywnych kupuje tylko bronie silne i precyzyjne - czyli takie, które nie zrobią mu przypadkiem krzywdy.
+
+* **Cyborg** - Obiera sobie za cel najsłabszego przeciwnika (o najmniejszym zasobie energii) lecz preferuje przeciwników sterowanych przez człowieka. Celuje bardzo dokładnie i w zdecydowanej większości przypadków trafia za pierwszym strzałem. Strzał oddaje najlepszą posiadaną bronią chyba że cel jest blisko. Wtedy zmienia broń na **Baby Missile** by unikać trafienia samego siebie. Broni defensywnych używa dokładnie tak jak **Chooser**. Zakupy robi dokładnie tak jak **Spoiler**
+
+* **Unknown** - Przed oddaniem każdego strzału losowo wybiera sposób działania od **Poolsharka** do **Cyborga** i stosuje jego taktykę. Taktyka zakupów broni jest jednak zawsze identyczna jak  **Tosser**
+
+Próba zakupu broni (ofensywnej lub defensywnej) wygląda następująco:
+Na początku losowana jest jedna z broni (wśród wszystkich możliwych ofensywnych lub defensywnych). Następnie wykonywane jest sprawdzenie czy wylosowana broń jest na liście broni możliwych do zakupu przez czołg. Jeśli nie to w tej próbie żadna broń nie jest kupowana, a jeśli tak, to sprawdzana jest jej cena. Jeśli czołg ma tyle pieniędzy, broń jest kupowana, w przeciwnym wypadku próba kończy się bez dokonania zakupu.

 ## Changes:
 
+###### Version 1.14
+2022-09-05
+
+Minor bugfixes and optimizations.
+Just a small update to allow for more testing and having fun before the bigger release.
+
+Changes:
+* Numerous optimizations that require a solid test. Please have fun and report issues!
+* Small DrawTanks fix.
+* Bouncy Castle bounces like it should.
+* Tracer and Smoke Tracer are not causing defense weapons to trigger anymore.
+* In rare cases direct hit was not accounted for correctly.
+* Manuals updated. 
+
+
+###### Version 1.13
+2022-08-30
+
+Getting ready for porting the game!
+
+Several heavy optimizations and code cleanups in preparation for an unexpected port.
+
+Changes:
+* Overhaul of AI - Cyborgs, Spoilers, and Choosers aim much better.
+* Cyborgs prefer to kill humans.
+* Fine tuning of AI purchases makes the difficulty level aligned with the robot level.
+* Fixed a very difficult and elusive bug that was causing tanks to freeze when falling close to the right edge of the screen fixed.
+* Updated music by @Miker
+* It is now possible to enter tank names with a joystick - all essential game functions are available without touching the keyboard!
+* Manuals updated with AI strategy information and more.
+
+
+###### Version 1.12
+2022-08-24
+
+What is going on? Are we getting crazy or what?
+
+Changes:
+* Background color indicates the type of walls. This is very useful when the rand option is selected.
+* XEGS users requested that console keys are used when no keyboard is attached! We delivered! [SELECT] to select an offensive weapon, [OPTION] to jump into inventory, defensive section, [START] + [OPTION] - immediate Game Over (no confirmation for you keyboardless folks)
+* A very silly bug detected by our young testers fixed - the game crashed when you built a very high mountain using Dirt Balls :)
+* Boxy infinite bounce bug fixed.
+* Funky bombs bounce off the walls!
+* The first letter entered for a tank name was inserted in the wrong spot. How did it work at all? Magic.
+[ESC] now correctly exits the purchase screen.
+
+
+###### Version 1.11
+2022-08-22
+
+A release lollapalooza.
+
+The silliness indicator crashed. What are we doing?
+
+Changes:
+* A very silly buffer overflow bug fixed - it allowed for infinite (well... to the point) lengths of tank names, or rather for overwriting code with arbitrary values.
+* Gamefield walls added https://github.com/pkali/scorch_src/issues/50. Choosing a different wall effect from the main options menu allows for a sophisticated tactics change.

+; http://raster.atari.org
+;
+; Warnings:
+;
+; 1. RMT player routine needs 19 itself reserved bytes in zero page (no accessed
+;    from any other routines) as well as cca 1KB of memory before the "PLAYER"
+;    address for frequency tables and functionary variables. It's:
+;	  a) from PLAYER-$03c0 to PLAYER for stereo RMTplayer
+;    b) from PLAYER-$0320 to PLAYER for mono RMTplayer
+;
+; 2. RMT player routine MUST (!!!) be compiled from the begin of the memory page.
+;    i.e. "PLAYER" address can be $..00 only!
+;
+; 3. Because of RMTplayer provides a lot of effects, it spent a lot of CPU time.
+;
+; STEREOMODE	equ 0..3			;0 => compile RMTplayer for 4 tracks mono

-;and on 2012-06-21 translated to mads
-;
-;game source code is split into 5+2 parts:
-;scorch.asm is the main game code (with many assorted routines)
-;grafproc.asm - graphics routines like line or circle
-;textproc.asm - text routines like list of weapons and shop
-;variables.asm - all non-zero page variables and constans
