Examples with Group com.badlogic.gdx.scenes.scene2d.Group used on opensource projects

Example 1 with Group

use of com.badlogic.gdx.scenes.scene2d.Group in project netthreads-libgdx by alistairrutherford.

the class SceneHelper method intersects.

/**
	 * Look for intersection between two actors.
	 * 
	 * I have defined this here as I can't extend the base classes Actor and Group.
	 * 
	 * @param x
	 *            The x pos rectangle.
	 * @param y
	 *            The y pos rectangle.
	 * @param width
	 *            The rectangle width.
	 * @param height
	 *            The rectangle height.
	 * @param group
	 *            The group.
	 * @param targetClass
	 *            The target class.
	 * 
	 * @return Target class, null if no intersection.
