C++ (Cpp) get_bone_from_selectbuffer Examples

Example #1

File: armature_select.c Project: bitfusionio/blender

/* x and y are mouse coords (area space) */
void *get_nearest_bone(bContext *C, short findunsel, int x, int y)
{
	ViewContext vc;

	rect.xmin = rect.xmax = x;
	rect.ymin = rect.ymax = y;
