We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I create a group PShape which includes a number of child PShape. I want to rotate one of the child PShape around its own axis instead of the axis of the group PShape. However, when I use getChild() and then use childname.rotateZ(), it always rotate around the axis of the group PShape:
PShape JL2 = JL12.getChild(1); JL2.rotateZ(0.01*PI);
Thank you very much!
