I was asked to make a mod that generate boxes that move from right to left First Attempt: I tried with Staticobject and move them with LUA but the collision mesh isn't refreshed Second Attempt: I tried to do a prop machine in jbeam but it have some limitation I have to make a closed loop because the cubes can be teleported (i think) rail with angles are not realeble (sometimes nodes pass very well, sometimes they don't) Speed control is horrible because of ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ I tried to break angles (you can see in the picture there is 2*45° and i did 3*30°) So i'm asking help for any idea or tweak that can help.
