virtual void	update (float)
	Updates the effect. Some effects may require shader parameters to be updated over time. This optionally overridable function passes in the current frame time and allows updating those parameters. This is called automatically when the effect is added to a Scene, but will need to be called manually when using the effect on its own.

Member Function Documentation

apply()

void xy::PostOldSchool::apply ( const sf::RenderTexture &  , sf::RenderTarget &    )

overridevirtual

Applies the effect.

Parameters

RenderTexture	A render Texture containing the scene to which the effect should be applied.
RenderTarget	The target to which the effected scene is rendered. This may be the current render window, or another RenderTexture when chaining multiple effects together.

The source and destinations are handled automatically by xygine when a post process effect is added to a scene, but must be specified maunally when using the effect outside the scene rendering.

Implements xy::PostProcess.
