Documentation
class HasComponentEnv env where Source #
emit :: (HasLoopEnv env, HasComponentEnv env, MonadIO m, EventType et) => et -> LightT env m () Source #
Emit a signal, which will be catched at the next frame.
class ComponentUnit c where Source #
CompoonentUnit typeclass provides a way to define a new component.
Any ComponentUnit instance can be embedded into Component type.

Methods
update :: (HasLightEnv env, HasLoopEnv env, HasComponentEnv env, MonadIO m, MonadMask m) => c -> LightT env m c Source #
Updating a model.
figures :: (HasLightEnv env, MonadIO m, MonadMask m) => c -> LightT env m [Figure] Source #
Descirbes a view. The figures here would be cached. See also useCache for the cache configuration.
draw :: (HasLightEnv env, MonadIO m, MonadMask m) => c -> LightT env m () Source #
Drawing a figures.
onSignal :: (HasLightEnv env, HasLoopEnv env, HasComponentEnv env, MonadIO m, MonadMask m) => Event -> c -> LightT env m c Source #
Event handlers
Arguments
| :: c | A model value in the previous frame |
| -> c | A model value in the current frame |
| -> Bool |
Return True if a cache stored in the previous frame should be used.
beforeClearCache :: (HasLightEnv env, MonadIO m, MonadMask m) => c -> [Figure] -> LightT env m () Source #
To be called just before clearing caches. If you want to destroy cached textures for memory efficiency, override this method.
NB: Freeing SDL textures and figures are not performed automatically. You must call freeFigure at your own risk.
Instances
A wrapper for ComponentUnit instances.
