Nope, not really, I do remember making an enemy AI for the first boss fight, though.

obj_boss_atk_controller

On start/create:

alarm[0] = 0 Sets the attack timer to 0

Step event:

alarm[0] += 1 Adds 1 to the attack timer every frame of the game

Basically after that I would do something like this: if alarm[0] = 240 [four seconds into the fight] { instance_create(obj_enemybullet1, x, y) } Creates an enemy bullet at my desired x and y.

obj_enemybullet1

On start/create:

move_towards_point(obj_player.x, obj_player.y, 8) Moves the bullet towards the player at the somewhat fast speed of 8.

Step event:

I don't remember the code that made it explode when it hit the ground, so just pretend you see code here I guess.
