【问题描述】：

我有两个节点——兔子和平板。我怎样才能让它通过对方，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;

【解决方案1】：

我相信您想将collisionBitMask 设置为物理体将碰撞的类别：

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

【解决方案2】：

我找到了解决办法：

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

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