I am trying to detect when a ball hits a character, I know I could use math but the ball is big and I would like to make a reallistic collision detection. With the "object collision" function it works in most of cases but coz the the movement step sometimes it just pass through the target, can you help me please?

make the object as long as fast your object will move
so if you make the speed 100 make object box 1,99,1,1
so now it will be a long streat line. i had the same prob
and thats what i use. dont forget to set object collision off whin it comes back or you will have a long stick and everything will get hit.

thanx , I have been thinkin about your idea and yes it will work fine, really thx, and about setting the collisions off... I use to delete objects when they finish their duty just to free memory, does it have sense?

no what you should do is use one object
try this code

sync on : sync rate 40
make matrix 1,100,100,10,10
color backdrop rgb(0,0,0)
make object box 1,99,1,1
hide object 1
position camera 50,20,50
do
cx#=camera position x()
cy#=camera position y()
cz#=camera position z()
if r=0
hide object 1
position object 1,cx#,cy#-1,cz#
if mouseclick()=1
r=1
endif
endif
if r > 0
move object 1,77
show object 1
if r > 10
r=0
endif
endif
sync
loop
