Я m making a test alien shooter game, where i want the player to gain points from shooting one kind of alien and lose from another. And when the player collides with the aliens he loses points. But i Я застрял с проблемой, что, когда я сталкиваюсь с инопланетянином (categorybitmask 0), ничего не происходит.Но когда игрок сталкивается с категорийной маской 1, он теряет очки.Мне нужно, чтобы он работал на обоих инопланетян.
Я пытался изменить маску категорий, коллизию битов и контактную маску, но ничего не работает.Я добавил много кода, чтобы вы могли видеть, как он висит вместе.
