如何创build自定义SKA？

你好，我想要做的就是创build一个类似于wheelRight.physicsBody.velocity = CGVectorMake(0, 1000); 到一个物理对象。

Answer 1

使用SKAction runBlock:方法：

 SKAction *changeVelocity = [SKAction runBlock:^{ wheelRight.physicsBody.velocity = CGVectorMake(0, 1000); }]; SKAction sequence = [SKAction sequence:@[..., changeVelocity, ..., ...]]; [wheelRight runAction:sequence];
