Ok so I am making a new game (Top Down Shooter), called Zombies Attack and I have come up on 2 problems that has me stuck!

1. Problem: Enemies

So my enemies (I'm gonna call them zombies now) are trying to kill me. Here is the code:

move_towards_point(obj_player.x,obj_player.y,2)
image_angle=point_direction(x,y,obj_player.x,obj_player.y);

Simple code to make them follow me, and face my direction.
But if I have multiple zombies in the room and they follow me for some time, they "overlap". Hope u know what I mean.. So what should I do?? D:


2. Problem: Shotgun

Ok so the player has weapons to defend himself (obviously). I so far made a normal pistol, and a mini uzi. But when it comes to the shotgun I am stuck...
When the player left clicks, obj_bullet is created at obj_player.x,obj_player.y and in the create event of the bullet it has this code:

image_angle=point_direction(x,y,mouse_x,mouse_y)
move_towards_point(mouse_x,mouse_y,20)

For the shotgun I want 5,6 maybe 7 bullets to fire out, and each bullet in its own direction, if that makes sense... And remember this is a Top Down Shooter. Any help would be appreciated.

a simple solution to your first problem is to use mp_potential_step like this:

mp_potential_step_object( player.x, player.y, 3, obj_zombie);

this will take steps towards the player and avoid instances of obj_zombie on the way there... you can change other options with the use of mp_potential_settings. However, this is a bit buggy so you might want to consider using one of the many A* dll's out there (espeically if you have other stuff in the way of the zombie and player)

to shoot multiple bullets say something like this:

in the mouse_left event that triggers the bullet being shot put

repeat(10)
{
   b = instance_create(x,y,obj_bullet);
   b.speed = 15 + random(4) - random( 4);
   b.direction = point_direction(x,y,mouse_x,mouse_y) + random( 25) -random( 25);
   b.image_angle = b.direction;
}

The use of all the randoms is just to make it look like it is spraying... you'll need to fiddle with these values to create the effect you want.
If you use this code then don't put the code you had above in the create event
