ghost collision detection

[gigaman]

i need to know if anyone can give me an idea of how to fix this. the enemies should change to a random direction when they hit a wall. eventually this will be put into a pacman program.

i don't know wat is wrong but you have to extract the file to be able to use it.

You know, you can combine conditions using or and and. Right now, you've got a ton of if statements that have the same code inside them, just different conditions.
Take this example:

code:

if x = 1 then   put x elsif x = 2 then   put x end if

that can be shortened to:

code:

if x = 1 or x = 2 then   put x end if

As for your problem, try switching the placement of your procedures. That is, call the collision procedure before the draw procedure. I believe the problem is that the picture covers up the blue line, so when the collision proc is called, it doesn't detect the blue line.

ok. i know what the problem is with it but i have no more ideas how to solve it. the problem is that when it reaches a side and move in that side's dorection again it is able to leave. example: if he starts at the top and goes down he cannot go daown again. however he can go right then go down again and leave. my idea was to have a sort of level system of whatdotcolours but that hasn't worked either. if soeone has an idea to solve this please help.
