libgdx - How to get the world coordinates of a point in a child actor? -


i have group objects consist of other group objects, consist of actor objects. now, when groups , actors rotated, offset , scaled, coordinates in "world", or in relation root node change. how world coordinates of point in actor's local space?

to illustrate bit more, here's example of want:

group parentgroup; actor childingroup; ... parentgroup.addactor(childingroup); childingroup.setposition(10f, 15f); childingroup.setrotation(45f);  // childingroup's position in world float childworldposx = ...; // want know float childworldposy = ...; // ... , this.

you can either use actor.localtoparentcoordinates() if want go 1 step higher in hierarchy of groups , actors, or directly use actor.localtostagecoordinates() "stage-global" coordinates directly. in case, libgdx recursively apply localtoparentcoordinates until hits root element of stage.
