I'm planning a MM1 engine and despite having almost all I need, I have difficulties to program the fortress bosses, thus being Yellow Devil, Copy Robot, CWU-01P and Wily Machine. Can anyone tell me how I program them?
This question is really too broad to answer well. Even if you just asked about on of them it'd be pretty broad. CWU-01P is one of the more straightforward ones. Break it down into it smaller and smaller parts. For example, create a spawner to spawn the boss. Then code the movement. Then code the shooting. And so on.
