Jak utworzyć SKPhysicsBody z otworami?-ios, swift, sprite zestaw, skphysicsbody

Zastanawiałem się, jak mogę stworzyć bardziej złożone ciało SKPhysicsyBody w ten sposób? Chcę najgorętsze poznać czarne części.

Wyeksportowałem ten kształt za pomocą PaintCode do CG Rect.

barrierpath2Path.moveToPoint(CGPointMake(52, 26))
barrierpath2Path.addLineToPoint(CGPointMake(52, 26))

monster.physicsBody = SKPhysicsBody(polygonFromPath: barrierpath2Path.CGPath)

Ale symulator pokazuje tylko jedną dziurę (i png z tyłu)? Co tu jest nie tak?

Odpowiedzi:

Najprawdopodobniej chcesz sprawić, by dziury były dziecinnewęzły z własnymi ciałami fizycznymi. Umożliwi to wszystkim posiadanie własnych ciał fizycznych i poruszanie się zgodnie ze sobą bez żadnych problemów

Aby rozwinąć tę odpowiedź, możeszmożna także użyć inicjatora wygody SKPhysicsBody, aby utworzyć ciało fizyczne z wartości alfa w teksturze. Spowoduje to pogorszenie wydajności, ale powinno robić to, co chcesz.

l.physicsBody = SKPhysicsBody(texture: l.texture, size: l.size)
