错误信息 | Error Message

const hitInfo = puer.$ref(); CS.UnityEngine.Physics.Raycast(originPos, CS.UnityEngine.Vector3.down, hitInfo); 在il2cpp打包下会报错

问题重现 | Bug reproduce

新建个空包执行脚本 const hitInfo = puer.$ref(); CS.UnityEngine.Physics.Raycast(originPos, CS.UnityEngine.Vector3.down, hitInfo); 打出il2cpp windows 包

https://github.com/Tencent/puerts/commit/fdd260b9c8b14aeba7ea0dbe284d6e7ccbb23dc5 看看是不是这个修的问题。

另外你截图的JS栈是drawDots，在往上也没有出现Raycast，有没有可能不是Raycast产生的问题

[dunadain]

换成最新版了 还是一样，drawdots里面调用了raycast

[dunadain]

感觉有俩个问题

1. new CS.UnityEngine.RaycastHit() 确实是无法创建（但好像不需要去new CS.UnityEngine.RaycastHit）
2. 上面代码 报错报在这个地方

[zombieyang]

这个ContactEventDelegate是怎么触发的？看上去RayCast不会用到 我测试了一下RayCast也没事（返回false）

  jsEnv = new JsEnv();

  RaycastHit rh;
  UnityEngine.Physics.Raycast(
      new UnityEngine.Vector3(0, 0, 0), 
      UnityEngine.Vector3.down, 
      out rh
  );
  jsEnv.Eval(@"
      const hitInfo = puer.$ref(null);
      console.log(CS.UnityEngine.Physics.Raycast(
          new CS.UnityEngine.Vector3(0, 0, 0), 
          CS.UnityEngine.Vector3.down, 
          hitInfo
      ))
  ");

这段代码打windows il2cpp 包运行 我直接就报错啊，难道是2022的问题？ TestRaycast.zip

[dunadain]

这个ContactEventDelegate 貌似2022.2以上才有这个东西

复现这样的错误，我看看

[zombieyang]

ContactEventDelegate所用到的NativeArray<ContactPairHeader>.ReadOnly在Runtime和Editor下获得的字段不同，Runtime下没有m_Safety属性

[dunadain]

是要写个filter吗？

[zombieyang]

https://github.com/Tencent/puerts/blob/master/unity/Assets/core/upm/Runtime/Resources/puerts/csharp.mjs#L61 目前发现是这里触发的，GetNestType时触发了RegisterType。这条链路还没法被Filter过滤。快捷点的话只能先在这里手动if过滤一下
