Question - Code Problem with enemy bullet directions

[Curry]

I'm creating a platformer game. I want the enemies to constantly shoot in the direction they're facing, but I'm having a problem: the direction of the enemy bullets are all in sync. (In other words, one of the enemies correctly shoots in whichever direction it is facing, but all the other enemies shoot in that same direction, regardless of the direction they're facing).

I think the reason for this is because 'obj_enemy' means all instances of obj_enemy, but I want individual instances of obj_enemy to shoot in their own directions. How can I fix this issue? Here's some of the code I'm using:

(obj_enemy step event)
//create bullets
instance_create_depth(x, y, 0, obj_bullet);

(obj_bullet step event)
//fire direction
if obj_enemy.image_xscale > 0 { //facing right
x += hsp; //bullet moves right
} else if obj_enemy.image_xscale < 0 { //facing left
x -= hsp; //bullet moves left
}

Make a distinction between objects and instances, and put the instance ID returned by instance_create_depth() to actual use.

NEVER access a single instance by object ID if multiple instances of the object exist. This includes attempts to reference or set object.variable (which is inconsistent across exports) and using with (object) to apply actions to it (this encompasses all instances of the object instead of just the one you want). Verbally, "Dog's colour" makes sense with one dog, but not with multiple dogs.

Created or copied instance. instance_create() (GMS 1.x and legacy) / instance_create_layer() (GMS 2.x) and instance_copy() return the ID of the created or copied instance. NEVER use instance_nearest() to establish this relationship --- something else could be closer by.

// Creating the bullet
var inst_bullet = instance_create_depth(x, y, 0, obj_bullet);
inst_bullet.hdir = sign(image_xscale);

// Bullet's Step event
x += hsp*hdir;
