8.DrawCall优化

8.1 知识点

在UIManager中的加载组件方法中，把加载好的组件的fairyBatching设置为true

/// <summary>
/// 加载组件 
/// </summary>
/// <param name="packageName">包名</param>
/// <param name="componentName">组件名</param>
/// <returns></returns>
public GComponent LoadComponent(string packageName, string componentName)
{
    //加载包
    UIPackage package = UIPackage.AddPackage("UI/" + packageName);
    //加载依赖包
    foreach (var item in package.dependencies)
    {
        UIPackage.AddPackage("UI/" + item["name"]);
    }
    
    GComponent component = UIPackage.CreateObject(packageName, componentName).asCom;
    //component.MakeFullScreen();
    
    //优化dc，只需要把面板组件fairyBatching设置为true
    component.fairyBatching = true;
    return component;
}

要在项目设置把动态批处理打开

查看DrawCall数量是否减少

调整分辨率，查看关联系统是否正确成功
