I have a small bit of code here and I was wondering if anyone would be kind enough to tell me why the two sprites in my code stick together when they collide. The images I am using in the code are two bitmap boxes that I created in Paint for quick demonstration purposes. They are 40 by 40 pixles.

Thank you for your help

please use the code tags instead of the code box during message entry. like this:

place

[/C0DE]

it will tuck your code away until someone opens it. like this:



so, since we can't see your code until you do that, about all i can do is ask if you're moving the sprites away from eachother once the collision is detected?

Sorry about that. Here's another try.

Also I should mention that I am using DBP with upgrade 5.7

Thank you again

[CODE]
sync on : sync rate 30
set display mode 800,600,16
backdrop on : color backdrop rgb(0,0,0)

load image "yell.bmp",1,1
load image "blue.bmp",2,1

yx=320
yy=320
bx=400
by=400

sprite 1,yx,yy,1
sprite 2,bx,by,2

do
oldyx=yx
oldyy=yy

if leftkey()=1 then yx=yx-5
if rightkey()=1 then yx=yx+5
if upkey()=1 then yy=yy-5
if downkey()=1 then yy=yy+5

if sprite collision(1,2)=1
yx=oldyx
yy=oldyy
endif

sprite 1,yx,yy,1


sync
loop
[/CODE]

Try putting this line:
sprite 1,yx,yy,1
before the collision check.
i.e.:


becomes:
