以下方法纯属我YY,切勿当真!!!
确定一个设计尺寸，比如 devWidth = 960,devHeight = 640, 按照这个尺寸进行设计游戏.
方式一: 不管什么屏幕尺寸,都和设计的尺寸对应.
只需在 Camera上 加上如下脚本:
public class ScreenAdapter : MonoBehaviour {
private Camera mainCamera;
private static float devWidth = 960f;
private static float devHeight = 640f;
private static float devAspect = devWidth / devHeight;
// Use this for initialization
void Start () {
mainCamera = Camera.main;
mainCamera.aspect = devAspect;
mainCamera.orthographicSize = devHeight * 0.01f / 2;
}
}
方式二: 只缩放背景图片.只需将如下代码放到背景上:
public class BgAdapter : MonoBehaviour {
private Camera mainCamera;
private static float devWidth = 960f;
private static float devHeight = 640f;
private static float devAspect = devWidth / devHeight;
// 背景完全显示在屏幕上
private bool mShowAll = true;
// Use this for initialization
void Start () {
mainCamera = Camera.main;
Vector3 scale = transform.localScale;
float sy = mainCamera.orthographicSize * 2 * 100/ devHeight;
float cameraWidth = mainCamera.orthographicSize * mainCamera.aspect * 2 * 100;
if (mainCamera.aspect > devAspect) {
// 会在左右留下空白,所以可以放大x
float sx = cameraWidth/devWidth;
scale.x = sx * sy;
if (!mShowAll) {
scale.y = scale.x;
}
transform.localScale = scale;
} else if (mainCamera.aspect < devAspect) {
if (mShowAll) {
// 会裁减左右,所以可以进行缩小 x
float sx = cameraWidth/devWidth;
scale.x = sx * sy;
transform.localScale = scale;
}
}
}
}
如果mShowAll为true,则进行适配的时候背景图片会进行不均匀的拉伸,但是图片不会被裁减掉
如果mShowAll为false,则进行适配的时候背景图片可能进行的是均匀的拉伸,但是图片会被裁减掉.
Over!!!
