AluraDrawer (SAluraDrawer)

#include "Saturn/Alura/AluraDrawer.h"

Inheritable class to allow for custom drawing onto the AluraCanvas.

This class is pure-virtual and all functions must be overridden!

class AluraDrawer : public SObject

Functions (public)

virtual void OnInit() = 0;
virtual void OnDraw( Timestamp ts ) = 0;
virtual void OnDestroy( Timestamp ts ) = 0;
virtual void OnEvent( Event& rEvent ) = 0;

Notes

OnInit is called when the Drawer is pushed back on to the AluraCanvas' drawer list. The same applies for OnDestroy.

It's best to not place any initialisation code in the constuctor and place it in the OnInit() function. Same rules applies for OnDestroy().

To add to an AluraCanvas call AddDrawer().
