Exercises When hit by a bullet, the Invaderoid continues its movement (i.e. it is a moving explosion). Similar to how you turned off the collision in the animation window above, try and prevent the Rigidbody from moving when the "Explosion" animation starts. o To make this easier to mark online - reduce the speed of the explosion animation in the Animator to 0.25 (instead of 1). Make another Animation that contains the Invader and Invader 2 Sprites and alternates between them every second. Add this Animation to the "Moving" State in the Animator Controller.
