I made a small game engine with a hierarchy, but have a with problem with applying transform down the hierarchy. I have an object with a parent, and I want the child to rotate around the parent with an offset (the childs
localPosition, relative to the parent, and a parent rotation).
For example, I have a parent "Earth", and a child "Moon". The "Earth" rotates, and the "Moon" rotates with a
100, 50 offset.
How do I rotate an object around another object with an angle and an offset?
Each object has:
- x / y
privatex / y
This is what I have, so far:
float atr = Deg2Rad(parent->GetGlobalRotation()); globalPosition.x = parent->GetGlobalPosition().x + cos(atr) * localPosition.x; globalPosition.y = parent->GetGlobalPosition().y + sin(atr) * localPosition.y;
but it only only on the x-axis if localPositon is
