I have motion on a box/square…it comes in the openes up btw: frames 10 through 25 <— @25 the box has done all i want it to do but now I want to add another motion and i like for this to keep moving…at frame 25 (box) i placed Stop(); in the action but when i do everything stops…I only want the box to stop and the lines to keep moving<the lines start at frame 26
