SOLVED Help with randomly creating instances within a room.

[AnnoyingDoggoX]

room_w = room_width
room_h = room_height
repeat (50)
{
    instance_create_layer(random(room_w), random(room_h), "Fish", obj_fish);
}

This code should create 50 randomly located instances of the obj_fish on the "Fish" instance layer of the room.
It runs fine but nothing happens.
It runs on room start in obj_fish.

Also, If I wanted to change this to an arbitrary rectangle in which the fish are created how would I do that?

What event for what object runs this code?

What event for what object runs this code?

The obj_fish object runs this code with the event being room start.

The obj_fish object runs this code with the event being room start.

the code will never run if there are no fish to begin with. Put the code somewhere else.
