## Defines
#define | CS_EVENTHANDLER_PHASE_2D(x)
| Use this macro to declare your event handler as wanting to handle the csevFrame event in the "2D" phase (i.e., after any handlers in the "3D" phase and before any handlers in the "console" phase).
#define | CS_EVENTHANDLER_PHASE_3D(x)
| Use this macro to declare your event handler as wanting to handle the csevFrame event in the "3D" phase (i.e., after any handlers in the "logic" phase and before any handlers in the "2D" phase).
#define | CS_EVENTHANDLER_PHASE_CONSOLE(x)
| Use this macro to declare your event handler as wanting to handle the csevFrame event in the "Console" phase (i.e., after any handlers in the "2D" phase and before any handlers in the "debug" phase).
#define | CS_EVENTHANDLER_PHASE_DEBUG(x)
| Use this macro to declare your event handler as wanting to handle the csevFrame event in the "Debug" phase (i.e., after any handlers in the "Console" phase and before any handlers in the "Frame" phase).
#define | CS_EVENTHANDLER_PHASE_FRAME(x)
| Use this macro to declare your event handler as wanting to handle the csevFrame event in the "Debug" phase (i.e., after any handlers in the "Console" phase and before any handlers in the "Frame" phase).
#define | CS_EVENTHANDLER_PHASE_LOGIC(x)
| Use this macro to declare your event handler as wanting to handle the csevFrame event in the "logic" phase (i.e., before any handlers in the "3D" phase).
