Example 1 with EntityRenderedListener

use of de.gurkenlabs.litiengine.entities.EntityRenderedListener in project litiengine by gurkenlabs.

the class RenderEngine method renderEntity.

/**
 * Renders the specified entity at its current location in the environment.
 *
 * <p>
 * This method uses the {@code IEntityAnimationController} to render the appropriate {@code
 * Animation}.<br>
 * If the entity implements the {@code IRenderable} interface, its render method is being called afterwards.
 *
 * <p>
 * To listen to events about this process, you can add a {@code EntityRenderListener} or {@code
 * EntityRenderedListener} to the render engine.
 *
 * @param g
 *          The graphics object to render on.
 * @param entity
 *          The entity to be rendered.
