Question

我在弄清楚如何使轮子网格渲染对象与Wheelcollider对象匹配时遇到了一些麻烦。我搜索了互联网，并找到了一些不同版本的统一的简短答案。

这是我目前的代码：

使用UnityEngine; 使用System.Collections;

public class Position : MonoBehaviour {

    public WheelCollider wc;
    public Transform tf;

    // Use this for initialization
    void Start () {

        wc = GetComponent<WheelCollider> ();
        tf = GetComponent<Transform> ();

    }

    // Update is called once per frame
    void Update () {

        transform.position = new Vector3 (tf.transform.position.x + (wc.suspensionDistance * 100), tf.transform.position.y);

我知道如何使这项工作请帮忙！

Answer 1

我不相信您需要通过在层次结构中正确设置组件来对此解决方案进行编码。

比方说，例如，您的WheelCollider半径为1（意思是直径为2），以距离为单位，默认Transform.Scale为1,1,1。

我们还说你有一个想要使用的三维车轮网格。例如，我们会说你以一定比例导入了这个模型，这样当放置在具有1,1,1的默认Transform.Scale的场景中时，它占据的半径为0.5个距离单位（意味着直径为2）。

在这种情况下，你可以简单地在游戏对象上安装WheelCollider，并将该对象作为另一个附加网格的游戏对象的父。那个儿童游戏对象可以有一个2,2,2的Transform.scale，并且可以直观地匹配WheelCollider的Radius Gizmo。

对于您的解决方案，这些数字会有所不同。首先在场景中确定WheelCollider半径（视觉上）的大小，然后将其置于轮网格中并按顺序应用Transform.Scale 。

请注意，之后更改WheelCollider的半径不会缩放子游戏对象。

Answer 2

OP 的代码和接受的答案都不正确。

OP 的代码很糟糕，因为它将轮子放在错误的位置（有时是对的，但通常是错误的）；并且接受的答案是错误的，因为它说您不需要代码来实现这一点。

Support for empty structs is deprecated and will be removed in the next stable version of Dart. Use Opaque instead. class Utf16 extends Struct { ^ /Users/vinnytwice/Developer/flutter/.pub-cache/hosted/pub.dartlang.org/ffi-0.1.3/lib/src/allocation.dart:47:33: Info: Support for using non-constant type arguments 'T' in this FFI API is deprecated and will be removed in the next stable version of Dart. Rewrite the code to ensure that type arguments are compile time constants referring to a valid native type. final int totalSize = count * sizeOf<T>(); ^ Unhandled exception: FileSystemException(uri=org-dartlang-untranslatable-uri:dart%3Ahtml; message=StandardFileSystem only supports file:* and data:* URIs) #0 StandardFileSystem.entityForUri (package:front_end/src/api_prototype/standard_file_system.dart:34:7) #1 asFileUri (package:vm/kernel_front_end.dart:599:37) #2 writeDepfile (package:vm/kernel_front_end.dart:738:21) <asynchronous suspension> #3 FrontendCompiler.compile (package:frontend_server/frontend_server.dart:554:9) <asynchronous suspension> #4 starter (package:flutter_frontend_server/server.dart:180:12) <asynchronous suspension> #5 main (file:///opt/s/w/ir/cache/builder/src/flutter/flutter_frontend_server/bin/starter.dart:13:24) <asynchronous suspension> FAILURE: Build failed with an exception. * Where: Script '/Users/vinnytwice/Developer/flutter/packages/flutter_tools/gradle/flutter.gradle' line: 991 * What went wrong: Execution failed for task ':app:compileFlutterBuildDebug'. > Process 'command '/Users/vinnytwice/Developer/flutter/bin/flutter'' finished with non-zero exit value 1 * Try: Run with --stacktrace option to get the stack trace.

不过，我确实推荐与已接受的答案中提出的相同的层次结构，因为它使事情更易于管理：

车辆
- WheelCollider1
  - WheelMeshRenderer1
- WheelCollider2
  - WheelMeshRenderer2
- 等等...

这是一个 MonoBehavior 脚本示例，如果您将其附加到每个 GetWorldPose 对象（根据上面的层次结构），该脚本将起作用：

WheelMeshRenderer#
