My object index is undefined?????

[Artuki]

levers = this.physics.add.staticGroup();

levers.create(200, 160, 'lever', frame = 0, true, 0);

 

console.log(lever.index) doesn't work in my overlap function. Apparently, index is undefined.

 

I want to link a lever to a bridge so I was going to set both bridge and lever to have index 0 in their respective groups.

Just curious, but why did you expect index to be defined in the first place? It's not a standard Group property, or a StaticGroup one either.

You could add it if you wanted though.

Because apparently phaser.group() in the documentation has 5 properties.... (x, y, key, frame, exists, index). @rich

That's in Phaser 2. In v3 it's (x, y, key, frame, visible)

Oh okay, thanks.

 

How do I do it then? @rich

[rich]

There's a few ways, but here's one:

var partA = levers.create(x, y, key);
var partB = levers.create(x, y, key);

partA.setData('index', 0);
partB.setData('index', 0);

function collide (a, b) {

  if (a.getData('index') === b.getData('index'))
  {
    // do stuff
  }

}

Thanks @rich, I will try this later on today. I'm doing this to link a lever to a bridge. So, I was going to treat their group indexes as lookup lists in a sense.
