Orientations

Orientations in OSRS are typically represented in JAU between 0-2048 where zero is facing directly south and each increment represents (1 / 2048f) * 360 = 0.17578125 degrees of clockwise rotation.

Interface IDs

In the game engine InterfaceComponents (often called Widgets) are structured in a 2-dimensional array. The ID of each Widget is a function of where it exists in that structure such that:

componentId = containerIndex << 16 | componentIndex

And the inverse:

InterfaceComponent ic = Interfaces.getAt(componentId >> 16, componentId & 0xFFFF)
