spritekit collisionBitMask通過彼此

Question

我有兩個節點 - 兔子和平板。我怎樣才能讓它通過對方，我做錯了什麼？

static const uint32_t rabbitCategory = 0x1 << 1; 
static const uint32_t slabCategory = 0x1 << 2; 

rabbit.physicsBody.categoryBitMask = rabbitCategory; 
rabbit.physicsBody.collisionBitMask = rabbitCategory; 
slab.physicsBody.categoryBitMask = slabCategory; 
slab.physicsBody.collisionBitMask = slabCategory; 

Answer 1

我找到了一個解決方案：

rabbit.physicsBody.categoryBitMask = rabbitCategory; 
rabbit.physicsBody.collisionBitMask = borderCategory; 

slab.physicsBody.categoryBitMask = slabCategory; 
slab.physicsBody.collisionBitMask = slabCategory; 

Answer 2

我相信你想設置的collisionBitMask到物理身體會發生碰撞類別：

rabbit.physicsBody.categoryBitMask = rabbitCategory; 
rabbit.physicsBody.collisionBitMask = slabCategory; 
slab.physicsBody.categoryBitMask = slabCategory; 
slab.physicsBody.collisionBitMask = rabbitCategory;
