if i create and place an object
example:
make object box 1,1,3,1 (thus a box of lenght 1 in x lenght 3 in y and lenght 1 in z)
and place it like this
position object 1,14,2,0
Is the middle of the object placed at these coordinates or is the left buttom corner of the object placed at these coordinates?

and if i make a plain and a sphere (the plain is 1 high and the sphere is 1) do they touch (in 2d over the y axis) at plain y coordinate +0.5 and sphere y coordinate -0.5 (if the sphere is comming from above the box)?

MAKE OBJECT BOX Object Number, X, Y, Z
POSITION OBJECT Object Number, X, Y, Z

if MATRIX 1 is 1024
then BOX 1 is centered if x=512, y=0, z=512

hope that helps
i'm new to this

I think (someone please verify) that collision works only with other objects

the distance between object and plain(matrix) is:

POSITION OBJECT Object Number, x=512, y=0, z=512

is that what you wanted?

dunno
besides i am using dbce, and its 2D so i don't really use a matrix, i working on making a breakout clone (how original of me ) and my paddle is a plain and the ball is a sphere and i want to know if i can use the object collicion command to detect if there is collision between these two objects, otherwise i ll have to calculate it, when they hit and do the same with the "blocks" you have to destroy with the paddle
