Add/Remove Layers from Layermask in graph?

[elvisish]

Is it possible to add or remove layers by name (or int) from a layermask or all layers in a graph? I understand it would require bit shifting:

<li style=”margin: 0px; padding: 0px; box-sizing: border-box; list-style: outside decimal; vertical-align: top;”>
layerMask <span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #008000;”>|=</span> <span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #008000;”>(</span><span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #ff0000;”>1</span> <span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #008000;”><<</span> <span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #ff0000;”>8</span><span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #008000;”>)</span><span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #008000;”>;</span>

<li style=”margin: 0px; padding: 0px; box-sizing: border-box; list-style: outside decimal; vertical-align: top;”>

layerMask <span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #008000;”>=</span> ~<span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #008000;”>(</span><span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #008000;”>(</span><span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #ff0000;”>1</span> <span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #008000;”><<</span> <span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #ff0000;”>9</span><span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #008000;”>)</span><span style=”margin: 0px; padding: 0px; box-sizing: border-box; color: #008000;”>;</span>

This way, I could just check for Everything besides layers (so when I add or remove layers, I don’t have to change any layermask references), but I’m not sure if it’s possible to do this with FC currently?

It would be very useful for testing against Everything besides a couple of layers, even after more layers have been added to the project (Everything except Enemies and Player, for instance, and at a later date, more layers such as Walls, Floors, Terrain may be added).

Hey,

I have attached for you here a package which contains some LayerMask method extensions (like Add/Remove to/from LayerMask as well as a ContainsLayer check). Please import the package and the extensions methods will show up under “LayerMask/Methods/Extensions” in the node browser for you to use. You can for example drag and drop a LayerMask output port as normal and under “LayerMask/Methods/Extensions” all the new methods will show up to be used as nodes.

Please let me know if that works for you 🙂

Thanks!

Sorry for the delay, been dying to try it for the last week and a half and needed to give it a good test! Works AWESOME, I used this to take a layermask Nothing and make it everything besides Water:

Not sure if this is the best way of doing it, but it works for me! This means I never have to worry about adding new layers and going through all of my old layermasks, I can just remove the layers I need excluding at the time. Thanks so much!

Hey,

I am glad it works for you. Yep that looks correct to me and the way I would do it 🙂

Thanks!
