This is my code and i dont know how to make it to where if i collide with sprite 2, then i stop as if it were a wall.

+ Code Snippet

sync on
sync rate 100
load image "floor.png",1
load image "floor.png",2
x#=0
y#=0
keystate(200)=0
keystate(208)=0
keystate(205)=0
keystate(203)=0
do
sprite 2,50,50,2
sprite 1,x#,y#,1
if keystate(200)=1 then dec y#,1
if keystate(208)=1 then inc y#,1
if keystate(205)=1 then inc x#,1
if keystate(203)=1 then dec x#,1
endif


sync
loop

Sprite Collision is a function in the sprite command set. So that seems like a good place to start looking when after information on doing sprite collisions

Hmm, I wonder what's coming in 2011?

yea sorry Beyond I just wrote that up on the spot. I havnt used dbpro 2d commands in a long time, but like Kevin said, look into the sprite commands and you should be set to go.

Keep in mind those commands will only detect a collision between the bounds of an image, and not really where the drawing within the image ends. If you want pixel perfect collision, then youll have to get more creative.

I'm sure there are a few collision threads here and there, try doing a search. There are many ways to work collisions and it also depends on the type of game it is for. What exactly did you want your two tiles to do, or what kind of game you making?
