问题描述

我在本教程中提出申请。

I am making application by this tutorial.

https://www.makegameswith.us/tutorials/getting-started-with-spritebuilder/spritebuilder-physics/

我直接在这样的代码中创建了jointnode

I made jointnode directly in code like this

_mouseJoint = [CCPhysicsJoint connectedSpringJointWithBodyA:_mouseJointNode.physicsBody bodyB:_catapultArm.physicsBody anchorA:ccp(0, 0) anchorB:ccp(34, 138) restLength:0.f stiffness:3000.f damping:150.f];

，但即使确定两个节点在同一CCPhysicNode下，

but even though surely two nodes are under the same CCPhysicNode,

它显示此错误

Bodies connected by a joint must be added to the same CCPhysicsNode,

有没有人有这个问题？

推荐答案

我有同样的问题，结果是我没有启用物理在_mouseNode。在节点上启用物理解决了问题。

I had the same problem, it turns out I had not enabled physics on the _mouseNode. Enabling physics on the node solved the problem.
