Hi! Great AI code! But it's not Actionscript, although the langauge is VERY similar. It's also VERY long. Tell me if you have problems with anything, and tell me what you think abotu the code.
Let me explain a few things:
"%" stands for mod which works like this a%b and returns the remainder of a / b. eg. 10%3 = 1
Built for a level that is 64 by 64, but that can be changed
the random works like this random(a,b), it returns a floating point >= a and < b.
playerscount is the ammount of players in the room.
onwall is like a hit detection for walls.
the command is:
if (onwall(x,y)) {
blah();
}
"^" is equal to power
eg. 9^.5=3
setcharani is a command that set the characters animation. This can easily be changed to gotoAndStop("moving") or whatever.
The properties are set up like this:
players[index].property,the properties used in this code are id (which is either 0 or 1, if it's 0 it's a baddy, of it's 1 it's a human player), and hearts (how many hearts the player has). The properties of the NPC that has the code are simply x, y, dir (ranges from 0 to 3), ect.
Timeout is a countdown (makes a very good loop)
eg.
if (playerenters) {
timeout = 0.05;
}
if (timeout) {
stuff();
timeout = 0.05;
}
There are many flags there are set by the game, ie playerenters, playertouchsme, wasthrown, ect. They're pretty self explanatory.
the message command print something above the NPCs head.
Well.... here we go!
