Unity—UGUI

UGUI在处理自适应Canvas Scaler。

我们要做的就是3DCamera的自适应。把下面这个脚本挂在Main Camera上即可。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

using UnityEngine; using System.Collections; using UnityEngine.UI; public class CameraScale : MonoBehaviour { void Start () { int ManualWidth = 960; int ManualHeight = 640; int manualHeight; if (System.Convert.ToSingle(Screen.height) / Screen.width > System.Convert.ToSingle(ManualHeight) / ManualWidth) manualHeight = Mathf.RoundToInt(System.Convert.ToSingle(ManualWidth) / Screen.width * Screen.height); else manualHeight = ManualHeight; Camera camera = GetComponent<Camera>(); float scale =System.Convert.ToSingle(manualHeight / 640f); camera.fieldOfView*= scale; } }

在UGUI中想设置一张全屏的背景图，但是直接设置 screen.width和screen.height后发现在有些分辨率下还是不能全屏。

rectTransform.sizeDelta
=
new
Vector2(Screen.width,Screen.height);

把如下脚本挂在需要全屏的Image对象上即可。

using
UnityEngine;

using
System.Collections;

public
class
UIMaskLayer
:
MonoBehaviour

{

void
Start()

{

int
width
=
Screen.width;

int
height
=
Screen.height;

int
designWidth
=
960;//开发时分辨率宽

int
designHeight
=
640;//开发时分辨率高

float
s1
=
(float)designWidth
/
(float)designHeight;

float
s2
=
(float)width
/
(float)height;

if(s1
<
s2)
{

designWidth
=
(int)Mathf.FloorToInt(designHeight
*
s2);

}
else
if(s1
>
s2)
{

designHeight
=
(int)Mathf.FloorToInt(designWidth
/
s2);

}

float
contentScale
=
(float)designWidth/(float)width;

RectTransform
rectTransform
=
this.transform
as
RectTransform;

if(rectTransform
!=
null){

rectTransform.sizeDelta
=
new
Vector2(designWidth,designHeight);

}

}

}
