public static void IgnoreLayerCollision (int layer1, int layer2, bool ignore= true);


2 つのレイヤーによるコライダーの衝突判定を無効化します

IgnoreLayerCollision は影響されたコライダーのトリガー状態をリセットします。そのため、この機能の呼び出しに応じて OnTriggerExit と OnTriggerEnter メッセージを受け取るかもしれません。

プロジェクトにおける Physics インスペクター上の任意のレイヤーの組み合わせのデフォルト値を設定できます。

//Attach this script to a GameObject and make sure it has a Rigidbody component
//Make a second GameObject with a Collider to test collisions on. Make sure both GameObjects are the same on the y and z axes

//This script stops collisions between two layers (in this case layers 0 and 8). Set up a new layer in the Inspector window by clicking the Layer option. //Next click “Add Layer”. Then, assign this layer to the second GameObject.

//In Play Mode, press the left and right keys to move the Rigidbody to the left and right. If your first GameObject is in layer 0 and your second GameObject is in layer 8, the collision is ignored.
