我目前正在尝试使用下面的代码渲染2D精灵表,其结果是仅渲染图像的背景色,并带有黑线。使用gimp将图像另存为.png文件。
我已经测试了从网上下载的随机精灵表,它们的渲染效果还不错。有没有办法我可能会错误地保存png文件?
框架大小应为27 x 27,即实际图像文件的高度,然后是我希望框架的宽度。
这是我当前正在使用的工作表:

最佳答案
您的矩形已关闭。 X / Y坐标(对于第一个索引)为0/27;您需要0/0。
黑线是spritebatch的人工产物,因为您要告诉它绘制不存在的东西。坐标0 \ 27没有图像。
看看Point currentFrame = new Point(0, 1);
。您为Y分配的值为1,但是您需要零。从零开始的索引,请记住:)
