3. 移动角色

学习目标

如何使用 Unity InputSystem 包在测试中以编程方式移动角色的通用方法。

锻炼

请确保 Unity 项目中安装了 InputSystem。您可以通过检查包管理器来验证这一点。

1. 创建一个名为MovementTest.cs下Assets/Tests/PlayModeTests.
2. 将引用附加到Unity.InputSystem和Unity.InputSystem.TestFramework在你的PlayModeTests装配定义。
3. 创建一个新的InputControl目录下的 Tests：Assets/Tests/InputControl.
4. 里面InputControl目录下，创建一个新的程序集定义：TestInputControl.asmdef.
5. 创建新类TestInputControl.cs在其中实现以下属性： public static bool MoveLeft { get; set; } public static bool MoveRight { get; set; } public static bool Jump { get; set; }
6. 返回到程序集定义PlayModeTests并将引用附加到新创建的：TestInputControl.
7. 最后，我们需要使用TestInputControl在实际的 LostCrypt 代码中。目前 Unity 的InputSystem不支持以编程方式进行模拟的更简单方法，请参阅此 git diff 以了解要更改的内容CharacterController2D:

diff --git a/Assets/Scripts/CharacterController2D.cs b/Assets/Scripts/CharacterController2D.cs

+        if (keyboard.leftArrowKey.isPressed || keyboard.aKey.isPressed || TestInputControl.MoveLeft)
             moveHorizontal = -1.0f;
-        else if (keyboard.rightArrowKey.isPressed || keyboard.dKey.isPressed)
+        else if (keyboard.rightArrowKey.isPressed || keyboard.dKey.isPressed || TestInputControl.MoveRight)
             moveHorizontal = 1.0f;
 
         movementInput = new Vector2(moveHorizontal, 0);
 
         // Jumping input
-        if (!isJumping && keyboard.spaceKey.wasPressedThisFrame)
+        if (!isJumping && (keyboard.spaceKey.wasPressedThisFrame || TestInputControl.Jump))
             jumpInput = true;
     } 

现在你准备好了！返回MovementTest.cs并编写一个测试，该测试不做任何断言（目前），而只是移动 Sara 角色并使其偶尔跳跃。

提示

• 您可能想要使用WaitForSeconds在测试中，故意让它运行更长时间，并看到屏幕上发生的实际动画。
• 如果出现编译问题，请确保遵循正确的文件夹结构：
