--[[
place this file under .minecraft/mods/ComputerCraft/lua/rom/programs
to make a game with this api, make a new file and type shell.run('gameapi') at the top, the functions will then be available for you to use.
Breif Explanation of Functions:
actor:new(x, y, char[, bounded])
returns a new actor at the x and y positions on the terminal
bounded is a boolean which will determine whether or not your actor's movement is limited to the console window, true by default.
actor.x
the actor's x position
actor.y
the actor's y position
actor.char
the character representing the actor on screen
actor.bounded
whether or not the actor can go outside the screen
actor:setPos(x,y)
sets the actor's position
**this method and other positioning methods must be used in order for the actor's position to be updated onscreen
actor:addPos(x,y)
adds to the actor's position
actor:setX(n)
sets the actor's x position to n
actor:setY(n)
sets the actor's y position to n
actor:addX(n)
adds n to the actor's x position
actor:addY(n)
adds n to the actor's y position
actor:setChar(char)
change the actor's character to char
game.key(k)
user defined, triggered when a key is pressed
game.update()
user defined, triggered when a new frame is drawn
game.start()
required for the game to start, obviously
**any code after this function will not be ran until the game has stopped
game.stop()
quit the program

/*---*/
Changelog:
r1:
Released API
r4:
Added 'game:setChar()' to change an actor's characters
Added a 'bounded' attribute if you wanted an actor to be able to go outside the screen.
Added 'screen.width' and 'screen.height' as editable attributes to allow for custom widths and heights
r5:
Changed instructions for usage.
