ios - SKPhysicsBody 大小与 resizeToHeight

Question

在调整他的 skspritenode 大小后，我遇到了物理体大小的问题。

我的代码:

backTop.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:backTop.size];
[backTop.physicsBody setAffectedByGravity:NO];
[backTop.physicsBody setDynamic:NO];
[backTop.physicsBody setCategoryBitMask:kPipeCategory];
[backTop.physicsBody setCollisionBitMask:kPlayerCategory];
backTop.physicsBody.usesPreciseCollisionDetection = YES;

//SKAction
SKAction *scaleBackTopActionStart = [SKAction resizeToHeight:backTop.size.height+kPipeGap duration:kPipeScale];
SKAction *scaleBackTopActionEnd = [SKAction resizeToHeight:pipeTop.size.height duration:kPipeScale];
SKAction *scaleBackTopSequence = [SKAction sequence:@[[SKAction waitForDuration:kPipeScaleStartWait],scaleBackTopActionStart, scaleBackTopActionEnd, [SKAction waitForDuration:kPipeScaleWait]]];

问题:

skspritenode 被调整大小但他的物理 body 没有跟随。你有想法吗？

比例只是一种视觉属性，不适用于物理体。除了创建具有适当缩放形状的新物体外，没有其他方法可以缩放物理物体。
