Hello, how do I make it so that it uses existing layers instead of creating a new one?

function __roomloader_create_layer(_data) {

    var _existing_layer = layer_get_id(_data.name);

var _layer = _existing_layer > -1 ? _existing_layer :  layer_create(_data.depth, _data.name);

layer_set_visible(_layer, _data.visible);

layer_x(_layer, _data.xoffset);

layer_y(_layer, _data.yoffset);

layer_hspeed(_layer, _data.hspeed);

layer_vspeed(_layer, _data.vspeed);

return _layer;

}

I modified this function like this but doesn't seem to work, thanks

Hey! This is something I'm planning to support officially as soon as I can, but for now there's no one-line fix that would work for all layer types.

Could you explain your exact use case? I might be able to help you get around this.

Thanks for the reply, glad to hear that it's planned! 

I have many layers in my game (150+) , and layers I need to load from another room have varrying depths, I don't wanna set the depth of the layers in external rooms as it will make it hard to make changes. IE if I add a new layer into my main room, now depth changes for all layers and I need to change it in all rooms etc. I also have code that operates on the layer names directly.
