With math you can also code moving collision.
An moving platform for example?
sync on
sync rate 60
Make object sphere 1,10
Make object plain 2,50,50
Make object cube 3,30
position object 3,50,0,0
xrotate object 2, 90
do
position object 2,object position x(2)+1.0,0.0,0.0
atop = 0
if object position x(1) > object position x(2)-object size x(2)/2
if object position x(1) < object position x(2)+object size x(2)/2
atop = 1
endif
endif
if atop = 1
position object 1,object position x(1)+1.0,object position y(1),object position z(1)
if object position x(1) > object position x(3)-object size x(3)/2-5
position object 1,object position x(1)-1.0,0.0,0.0
endif
else
position object 1,object position x(1),object position y(1)-1.0,object position z(1)
endif
point camera object position x(1),object position y(1),0
sync
loop
This is just a basic idea for moving platforms

This only took me 3 minutes to code (and figure out how to do it)
