问题描述

我不明白如何在 SpriteKit 中创建连接两个物体的关节.感谢您的帮助.

I don't understand how to create a joint to connect two bodies in SpriteKit. Thanks for help.

推荐答案

所有关节类型的原理都是一样的.首先，使用一些附加参数创建连接两个主体的关节(请参阅 Sprite Kit 框架参考 了解详情).然后将新创建的关节添加到物理世界:

The principle is the same for all joint types. First, create a joint connecting two bodies with some additional parameters (refer to the Sprite Kit Framework reference for details). Then add the newly created joint to the physics world:

CGPoint anchor = CGPointMake(100, 100);
SKPhysicsJointFixed* fixedJoint = [SKPhysicsJointFixed jointWithBodyA:aBody 
                                                                bodyB:otherBody
                                                               anchor:anchor];
[self.scene.physicsWorld addJoint:fixedJoint];

现在抽它！
