以下是完整的代码示例,用于在Unity Webgl中将一个场景界面缩小并放置在另一个场景界面中:
```csharp
using UnityEngine;
using UnityEngine.UI;
public class SceneController : MonoBehaviour
{
public Camera mainCamera; // The camera used for the main UI canvas
public Canvas mainCanvas; // The main UI canvas
public RawImage sceneImage; // The RawImage used to display the scene
public Camera sceneCamera; // The camera used to render the scene
public Canvas sceneCanvas; // The canvas used to display the scene
private RenderTexture renderTexture; // The RenderTexture used to render the scene
void Start()
{
// Set up the RenderTexture
renderTexture = new RenderTexture(Screen.width / 2, Screen.height / 2, 24);
renderTexture.Create();
// Set up the RawImage to display the RenderTexture
sceneImage.texture = renderTexture;
// Set up the camera to render to the RenderTexture
sceneCamera.targetTexture = renderTexture;
// Set up the canvas to display the RawImage
sceneCanvas.worldCamera = sceneCamera;
sceneCanvas.sortingOrder = 1;
// Set up the main canvas to display the scene
mainCanvas.worldCamera = mainCamera;
mainCanvas.sortingOrder = 0;
// Hide the scene canvas initially
sceneCanvas.gameObject.SetActive(false);
}
void Update()
{
// Render the scene to the RenderTexture
sceneCamera.Render();
}
public void ToggleSceneCanvas()
{
// Toggle the visibility of the scene canvas
sceneCanvas.gameObject.SetActive(!sceneCanvas.gameObject.activeSelf);
// If the scene canvas is visible, set the RawImage to display the RenderTexture
if (sceneCanvas.gameObject.activeSelf)
{
sceneImage.texture = renderTexture;
}
}
}
```
在这个示例中,我们有两个Canvas:一个主Canvas和一个场景Canvas。主Canvas用于显示所有其他UI元素,而场景Canvas仅用于显示缩小的场景界面。
在Start函数中,我们设置了RenderTexture、RawImage、Camera和Canvas。我们还将场景Canvas设置为不可见,因为我们希望用户可以通过单击按钮来切换可见性。
在Update函数中,我们每帧都将场景渲染到RenderTexture中。
最后,我们有一个名为ToggleSceneCanvas的公共函数,用于切换场景Canvas的可见性。当场景Canvas可见时,我们将RawImage的纹理设置为RenderTexture。
您可以将此脚本附加到任何游戏对象上,并将相应的场景界面相机和UI元素分配给相应的公共变量。
希望这可以帮助您实现所需的效果!
