Description

物理エンジンにより生成された衝突情報

全ての衝突情報は衝突地点、法線、および衝突した二つのコライダーを含みます ( ContactPoint を参照) OnCollisionStay または OnCollisionEnter の中には 必ず contacts が最低一つ含まれます。

		for (var contact : ContactPoint in collision.contacts) {
			print(contact.thisCollider.name + " hit " + contact.otherCollider.name);
			// Visualize the contact point
			Debug.DrawRay(contact.point, contact.normal, Color.white);
		}
