我把一个源码的图片替换成和原图不一样尺寸的后，不显示图片啦？

[king_small_smaller]

哪位大神知道怎么回事？
源代码的一张图片被我替换成尺寸不一样的图片后，图片就不显示了，一片黑，
替换成和原图一样尺寸的可以显示？

我替换的是tu.png

[lcf]

texture = new Texture(512, 256, TextureOptions.BILINEAR); 这句决定了能显示的贴图大小，你重新建一个Texture对象估计就o了

引用 3 楼 lcf 的回复:

大神 小弟实在愚笨，捣鼓半天也没弄好， 原图470*185 我的目标图：480*800 可否请您再指点一二？

[lcf]

camera width 和 hieght 应该不关贴图事啦
