scene, but the run animation never plays back during the move, and so the Enemy simply looks like
he's hovering or sliding around the level. Creepy! So let's change that now. To do this, we'll return to the
Enemy_Drone class and make use of the SendMessage functionality, coded earlier in Listing 7-6, where the
ChangeState function sends a change state message to the enemy object. We'll use this message to
initiate playback of the relevant animation (see the amended Enemy_Drone script in Listing 7-8).
