spritekit collisionBitMask互相传递

Question

我有两个节点 - 兔子和平板。我怎么能让它通过彼此，以及我做错了什么？

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

我相信你想将collisionBitMask设置为物理体碰撞的类别：

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

Answer 2

我找到了解决方案：

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

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