Creating unique objects

[Arrogant]

I have a problem with wanting the same objects to be separate from one another. I have a button which when activated it powers a object called wire, although it will power all the wires if only one of them is touching the button (GIF of the problem: https://gyazo.com/c6d769055e9aba089b9a1af6da0d31f7).

Step event code of the wire:

Spoiler

if(place_meeting(x,y, obj_wallbutton) && obj_wallbutton.powered == 1)
{
image_index = 1;
}
else
{
image_index = 0;
}

Step event code of the button:

Spoiler

if collision_rectangle(x+7,y+7,x+14,y+14,obj_clight, false, true)
{
image_speed = 0.5;
if(image_index == 15)
{
powered = 1;
image_speed = 0;
image_index = 15;

}
}
else
{
image_speed = -0.5;
if(image_index == 0)
{
powered = 0;
image_speed = 0;
image_index = 0;
}
}

So how would I go about only changing the state of the wire which is touching the button instead of all the wire objects? Also as shown in the GIF, only one of the buttons powers the wire, how could I change this?
Please excuse me if the problem is obvious, i'm very tired
Thanks in advance.

Hi and welcome to the GMC!

Can wires be connected to each other?
Looking at your code, I'd guess not.

In that case, you can just simply change the step event of the wire object to:

image_index = 0;
with obj_wallbutton
    if powered && place_meeting(x, y, other) {
        other.image_index = 1;
        break;
    }

Otherwise, try this:
1) Delete the step event of the wire object
2) Put in the begin step event of the wire object: image_index = 0;
3) Put in the event user 0 event of the wire object:

if image_index == 0 {
    image_index = 1;
    for(var i = 0; i < 360; i += 90)
        with instance_place(x + lengthdir_x(1, i), y + lengthdir_y(1, i), obj_wire)
            event_user(0);
}

(You might need to change this a bit to get the correct distances and directions)

4) Add this to the step event of obj_wallbutton:

for(var i = 0; i < 360; i += 90)
    with instance_place(x + lengthdir_x(1, i), y + lengthdir_y(1, i), obj_wire)
        event_user(0);

3) Put in the event user 0 event of the wire object:

Sorry i'm relatively new to game maker, where do I find/create this?

 

[jo-thijs]

It is categorized as an "other" event.
Then go to the user defined events.

 

[Arrogant]

Not sure if I have done it wrong, but doing this gives all the wire objects a constant power?

 

[jo-thijs]

No, I made a mistake.
4 should have been:

if powered
    for(var i = 0; i < 360; i += 90)
        with instance_place(x + lengthdir_x(1, i), y + lengthdir_y(1, i), obj_wire)
            event_user(0);

Thanks so much it worked well and I was able to implement it to work with other objects, but it powers only 2 of the wires and the second wire in that sequence is powered determined by when they were created.
(e.g.
https://gyazo.com/efbb672a6bd674ec2dc5078636a1a9aa
In that gif the two powered wires were put into the editor before the top one.)
Anyway to fix this?

 

[jo-thijs]

Hm, it should not be based on which wire is created first.
Are you sure it depends on this?

I also wonder, what is the size and shape of a wire?
How are they created?

 

[Arrogant]

Well I tested putting the wires in, in different orders and it always powered the wire I put in first.
(gif of what happens when I put the top wire into the editor first: https://gyazo.com/668fb07ff1794f2506c5a05b7a450a97)

The size of the initial wire is 4*4 pixels, but in the editor I stretch them but keep either 4 pixel width or 4 pixel height.

 

[jo-thijs]

Oh, I see.
Your wires overlap and are quite long.
I should have mentioned that I based my code on a tile mechanism.

Anyway, try this as new user defined event of the wire objct:

if image_index == 0 {
    image_index = 1;
    for(var i = 0; i < 360; i += 90)
        with obj_wire
            if place_meeting(x + lengthdir_x(1, i), y + lengthdir_y(1, i), other)
                event_user(0);
}

and this as the code in the step event of obj_wallbutton:

if powered
    for(var i = 0; i < 360; i += 90)
        with obj_wire
            if place_meeting(x + lengthdir_x(1, i), y + lengthdir_y(1, i), other)
                event_user(0);
