2 つのコライダーの衝突判定を無効化します

This is useful, say, for preventing projectiles from colliding with the object that fires them.

Note that IgnoreCollision will reset the trigger state of affected colliders, so you might receive OnTriggerExit and OnTriggerEnter messages in response to calling this. IgnoreCollision has a few limitations:

1) It is not persistent. This means ignore collision state will not be stored in the editor when saving a scene.
2) 有効なゲームオブジェクトにしか IgnoreCollision を適用できません。
