When I start my program and press "N" to create a new cube, the cube is added to a list and rendered. However, with the addition of each new cube, it seems to save the position of the previous one and create any new cube at that spot. Feeling a little frustrated. I don't see how it's
overwriting the initialized position that I give it :
objects_Render.append(
Cube_Projectile((0.0,0.0,0.0))
)
What am I doing wrong?
