With the 18 levels set up, they all have enemies inside but without any animation. I have focused mainly on the bird enemies Don Pigieone, Al Coopone and Joe Pecksi.
There’s a tool called ‘Matinee Legacy’ which allows you to give a sprite some movement.
For example, I want to give movement to the enemy sprite Don Pigeone. First you must do the following ‘Add Empty Group’ > ‘Select Actor’ > ‘Add Movement Track’. Keyframes are added to keep track of animation, I have set up keyframes at 0, 2.5 and 5 seconds for consistency.
