Hi djtoon,

what do you mean?
You mean sth. like this?

Code (glbasic) Select Expand


local col=false
local x;y

while true
if col=false
x=spriteX
y=spriteY
endif

if sprcoll(...) then col=true
showscreen
wend


if col is true then you should have the last position without collision in x and y...

[djtoon]

if the to sprites are 50x50px then where did thay hit
at 40x40 or where becose it does box coll befor pixel coll

I dont think there is an efficient way - you need to examine the pixel of each sprite to determine where the overlap is - which would be slow.

The much better alternative would be to split the sprites up into smaller ones, and then you can at least detect whereabouts the collision occurred.

not to mention if the sprites overlap totally, where exactly do you count the hit? Upper left corner? Middle?
