Determines if the frame alternator value for this entity matches the engine's frame alternator value. The entity's frame alternator value will be set to match the engine's after each call to the entity.tick() method so the return value of this method can be used to determine if the tick() method has already been run for this entity.

This is useful if you have multiple viewports which will cause the entity tick() method to fire once for each viewport but you only want to execute update code such as movement etc on the first time the tick() method is called.

var tickAlreadyCalled = entity.newFrame();
