 How to play    \__
----------------/__\

The program starts in the setup toolbar, where you can customize your game to suit your moods or tastes.There are three dialog boxes for the many options in the configure menu, organized by player, firing options, and terrain. These affect gameplay and speed.

Press "Game: Start" for a new game. Alternatively, you can skip your startup toolbar altogether by creating a file named bypass". It doesn't matter what it is: a macro, data, expression, whatever. If it exists, and the setup is valid, the toolbar is bypassed and goes straight to the start. Of course, you should save the setup list before using this feature.

The current graph is stored, and the program begins to generate the terrain. Once it is drawn, a popup will allow you to select a human or any of the installed computer players in playing order. If no computer players are installed, the popup is not shown. When you are done, the game will draw the tanks in sequential order. From then on, the play will cycle from left to right. An arrow near the top of the screen will indicate the current player's tank and respond to the controls below:

Quick reference: Keys
--------------------
F1                   Shows the Quick Reference dialogs

UP and DOWN          increase and decrease power
LEFT and RIGHT       adjust your angle left and right
Enter or Space       fires
ESC                  ends the round
[2nd]-QUIT           immediately exits the game

APPS                 invokes the aim dialog box
Clear or F4          redraws the screen, clearing out the dead tanks

p                    saves a screen shot as a pic (screen capture)
                     (active only in human controls or after firing)
[STO->]              saves a game (input an index name)

Included Files

 Players        \__
----------------/__\

• pcalc - Calc - Selects a random target, a random angle in the general direction of the target, and a power calculated to hit the target for the given angle.
• pdumb - Dummy - Picks a random power and angle and relies on pure luck.
• persist - Persistent - Like pcalc, but keeps aiming for an existing target before looking for a new one. If at first you don't succeed...
• pbounce - Bouncer - Picks a random target, checks for Rubber walls and then aims off the ceiling for the target. It doesn't correct for gravity properly, but it is much better at hitting targets behind hills.
• pdirect - Direct - Picks a random target, but relies on line-of-sight to shoot directly at it, sometimes shooting through hills to do so.
• pthief - Thief - Steals ideas from other installed functions, or acts like a dummy if it fails to find anything to steal.
• pbigot - Bigot - Like pcalc, only this strategy favors targeting human players first.

• a - the current game's setup list, similar to 'set'.
  • a[1] - # of players
  • a[2] - bomb scale (bomb radius)
  • a[3] - terrain height
    1=Speed Bump, 2=Hillside, 3=Mountain, 4=Sky's The Limit
  • a[4] - terrain width
    1=Jagged, 2=Narrow, 3=Normal, 4=Wide
  • a[5] - maximum wind speed
    
  • a[6] - traced paths
    
  • a[7] - border type
    1=None, 2=Wrap Around, 3=Rubber
  • a[8] - Tank Designs
    
  • a[9] - Animate Falls
    
• b - Player data. For any player j:
  
  • b[j,1] - x location
  • b[j,2] - the angle (in degrees from straight up)
  • b[j,3] - power
  • b[j,4] - type number (access to playlist functions)
    1=Human, 2,3,...,n=#(playlist[n-1])
  • b[j,5] - y location.
• i - Current player. This will tell you which row of b contains your information.
• r - Terrain list. The length of the list is the number of pixels across divided by 2.
• w - Current wind speed to the right (left is negative wind speed)

By referencing the playlist with the type number, such as with playlist[b[j,4]-1], you can obtain the name of any other installed player and even attempt to access it. The Thief strategy uses this trick to steal the strategies used by other players. A counter-strategy may check for the Thief's spoofing and then respond in its own favor.
