Unity 分享 和 不同分辨率适配
Canvas Scaler适配模式Canvas Scaler https://blog.csdn.net/st75033562/article/details/52355239
================================
需要截图的屏幕，只需要截取中间羊皮纸的部分
截图效果：
我们选的Canvas Scale缩放模式为 Scale With Screen Size -> Expand
直接上代码:
public class ShareImage : MonoBehaviour {
[CSharpCallLua]
public delegate void ShareCB();
//分享摄像机
Transform shareCamera = null;
//分享摄像机上面的targetTexture
public RenderTexture showImage = null;
[SerializeField]
private RectTransform BGImage = null;
int width = 1136;
int height = 640;
int posX = 0;
int posY = 0;
void Awake()
{
float multiplyX = Screen.width / 1136f;
float multiplyY = Screen.height / 640f;
float multiply = 1;
posX = 0;
posY = 0;
if ((Screen.width / 1136f) < (Screen.height / 640f))
{
multiply = Screen.width / 1136f;
posX = (int)((1136f / 2 + BGImage.anchoredPosition.x) * multiply);
posY = (int)((640 / 2 + BGImage.anchoredPosition.y) * multiply + Screen.height / 2f - 640f / 2 * multiply);
}
else
{
multiply = Screen.height / 640f;
posX = (int)((1136f / 2 + BGImage.anchoredPosition.x) * multiply + Screen.width / 2f - 1136f / 2 * multiply);
posY = (int)((640 / 2 + BGImage.anchoredPosition.y) * multiply);
}
width = (int)(BGImage.sizeDelta.x * multiply);
height = (int)(BGImage.sizeDelta.y * multiply);
}
