Question

I’m creating objects, instances of ofNode, let call them cards. Every card has it’s own properties, like buttons, text and images, which are drawn in card .draw() function.

If I change card location “children” objects aren’t moving along. Is there any way to bind their position to their card object?

Answer 1

Use the setParent method:

ofNode parent;
ofNode child;
child.setParent(parent);

parent.setGlobalPosition(10, 20, 30);
child.setPosition(100, 200, 300);

ofVec3f pos = child.getGlobalPosition(); // pos == (110, 220, 330)

Note that setPosition is local, which is related to its parent position, while setGlobalPosition is global.
