Physics Layers

How to work with Unity Game Object layers in Airship

Airship reserves layers 0-16 for internal use. Every other layer is available for use by game devs.

These layers are named GameLayer[0-31] but can be renamed as you see fit.

You may also change the Physics Matrix for these layers. Read more about the Physics Matrix here.

In Typescript you can use the layers via their name or index. You can easily get their index with the GameLayer static Enum.

// Create a mask from layer names
const layerMask = LayerMask.GetMask("GameLayer0", "GameLayer1");

// Check if an object is a game layer
if (this.gameObject.layer === GameLayer.GAMELAYER_0) {

	//Raycast with a game layer mask
	if (Physics.Raycast(this.transform.position, this.transform.forward, 10, layerMask)) {
		print("Hit a game layer object");
	}
	
}

You can revert core layers you have renamed by using the menu button
