GML How could I make/program enemies?

[GalGames]

Hi. I'm making a Scrolling Shooter for practice and I wanna know how I could I make enemies.



I tried putting the same code of the obj_player in the enemy event and it didn't work. What code could work? I looked for tutorials on YT but there's only tutorials for a plataformer enemy and when I found the "perfect tutorial" it's drag and drop.

Need help.

What do you want the enemies to be able to do?

Shoot and move...

Shoot and move...

When do you want them to move, how do want them to move, when do you want them to shoot?

For the movement, look for tutorials on paths. Each wave of enemies will follow a path, and spawn in short succession in order to create the wave.

For shooting, you can run something like this in the enemy create and step.

//create
//how often to attack
attack_time_initial = room_speed;
attack_time = attack_time_initial;
bullet_speed = 10;

//step
if attack_time <= 0 {
  //get direction to player
  var dir_ = point_direction(x, y, o_player.x, o_player.y);

  //create bullet
  var inst = instance_create_depth(x, y, depth, o_bullet);
  inst.direction = dir_;
  inst.speed = bullet_speed;
 
  //reset attack
  attack_time = attack_time_initial;
} else attack_time--;

Thanks you so much! I'll look for paths.

You'll also want to look into state machines if you want to cycle between different behaviors
