Function Documentation

ecs_app_run()

FLECS_API int ecs_app_run	(	ecs_world_t *	world,
		ecs_app_desc_t *	desc )

Run application.

This will run the application with the parameters specified in desc. After the application quits (ecs_quit() is called) the world will be cleaned up.

If a custom run action is set, it will be invoked by this operation. The default run action calls the frame action in a loop until it returns a non-zero value.

Parameters

world	The world.
desc	Application parameters.

ecs_app_run_frame()

FLECS_API int ecs_app_run_frame	(	ecs_world_t *	world,
		const ecs_app_desc_t *	desc )

Default frame callback.

This operation will run a single frame. By default this operation will invoke ecs_progress() directly, unless a custom frame action is set.

Parameters

world	The world.
desc	The desc struct passed to ecs_app_run().

Returns

value returned by ecs_progress()

ecs_app_set_frame_action()

FLECS_API int ecs_app_set_frame_action

(

ecs_app_frame_action_t

callback

)

Set custom frame action.

See ecs_app_run_frame().

Parameters

callback

The frame action.

ecs_app_set_run_action()

FLECS_API int ecs_app_set_run_action

(

ecs_app_run_action_t

callback

)

Set custom run action.

See ecs_app_run().

Parameters

callback

The run action.
