UGUI系列-屏幕自适应多分配率适配(Untiy3D)

UGUI屏幕自适应(多分配率适配)

1、Canvas的属性配置

2、Canvas Scaler的属性配置

3、根据不同的屏幕的比例动态修改缩放基准

代码语言：javascript复制

void Start ()   
{  
        float standard_width = 960f;        //初始宽度  
        float standard_height = 640f;       //初始高度  
        float device_width = 0f;                //当前设备宽度  
        float device_height = 0f;               //当前设备高度  
        float adjustor = 0f;         //屏幕矫正比例  
        //获取设备宽高  
        device_width = Screen.width;  
        device_height = Screen.height;  
        //计算宽高比例  
        float standard_aspect = standard_width / standard_height;  
        float device_aspect = device_width / device_height;  
        //计算矫正比例  
        if (device_aspect < standard_aspect)  
        {  
            adjustor = standard_aspect / device_aspect;  
        }  
  
        CanvasScaler canvasScalerTemp = transform.GetComponent<CanvasScaler>();  
        if (adjustor == 0)  
        {  
            canvasScalerTemp.matchWidthOrHeight = 1;  
        }  
        else  
        {  
            canvasScalerTemp.matchWidthOrHeight = 0;  
        }  
}  

效果：

canvas
