从零开始学习GameFramework 1.打开一个UI界面

最先最先建立一个 GameEntry.cs 脚本

https://gameframework.cn/tutorial/tutorial-003/ 根据官方教程的建议去创建使用

UI界面脚本必须继承 UIFormLogic

GameFramework 预制体组件下有个 UI 子物体，默认 UIGroupHelper是DefaultUIGroupHelper，需新建一个继承 UIGroupHelperBase 脚本的项目配置

public class UGuiGroupHelper : UIGroupHelperBase
{
    public const int DepthFactor = 10000;
    private Canvas m_Canvas = null;
    private int m_Depth = 0;
    
    private void Awake()
    {
        m_Canvas = gameObject.GetOrAddComponent<Canvas>();
        gameObject.GetOrAddComponent<GraphicRaycaster>();
    }

    private void Start()
    {
        InitRectTransform();
        InitCanvas();
        InitCanvasScaler();
        m_Canvas.sortingOrder = DepthFactor * m_Depth;
    }

    private void InitRectTransform()
    {
        var rectTransform = GetComponent<RectTransform>();
        rectTransform.anchorMin = Vector2.zero;
        rectTransform.anchorMax = Vector2.one;
        rectTransform.anchoredPosition = Vector2.zero;
        rectTransform.sizeDelta = Vector2.zero;
    }
    
    private void InitCanvas()
    {
        m_Canvas.renderMode = RenderMode.ScreenSpaceOverlay;
    }
    
    private void InitCanvasScaler()
    {
        var canvasScaler = gameObject.GetOrAddComponent<CanvasScaler>();
        canvasScaler.uiScaleMode = CanvasScaler.ScaleMode.ScaleWithScreenSize;
        canvasScaler.referenceResolution = new Vector2(1920, 1080);
        canvasScaler.screenMatchMode = CanvasScaler.ScreenMatchMode.MatchWidthOrHeight;
        canvasScaler.matchWidthOrHeight = 0.8f;
    }

    public override void SetDepth(int depth)
    {
        m_Depth = depth;
        m_Canvas.overrideSorting = true;
        m_Canvas.sortingOrder = DepthFactor * depth;
    }
}

创建一个UIGroup(图片引自 https://blog.csdn.net/weixin_42066580/article/details/117691546 )

OpenUI

GameEntry.UI.OpenUIForm("UI预制体路径(路径一定要包含 "Assets/")","UI预制体所属的UIGroup")

修改 UIFormLogic 脚本(OnInit方法内添加)

var rectTransform = gameObject.transform as RectTransform;
rectTransform.anchorMin = Vector2.zero;
rectTransform.anchorMax = Vector2.one;
rectTransform.anchoredPosition = Vector2.zero;
rectTransform.sizeDelta = Vector2.zero;
