Hi,

I had an object which had its local +Z axis as pointing FRONT. The object can be rotated respect to its local X, Y and Z axis, as it is an aeroplane.

How do I calculate the coordinate 40 units from the object position to where it is currently pointing, i.e. where its local +Z axis is pointing now.

I heard this can be done using NewXvalue(), NewYvalue(), and NewZvalue() command? How can I do that?

Thanks!

Maybe something like this, where the object number is 1, I'm not sure if I've got the angles arranged correctly, you'll have to test it out.

xpoint=newxvalue(object position x(1),object angle x(1),40)
ypoint=newyvalue(object position y(1),object angle y(1),40)
zpoint=newzvalue(object position z(1),object angle z(1),40)

If it's just a 2d coordinate your looking for you'll only need 2 of the above. Usually x and z if your looking down on it.
