修复LWJGL 3和Slick-Util

标签： java eclipse opengl rendering lwjgl

我要做的是将纹理映射到LWJGL中的OpenGL模型。我知道LWJGL 3和slick-util有时会一起工作，有时候也不会。在我的情况下，它工作了一点，然后尝试访问OpenGL中不再存在LWJGL 3的方法。我发布这个并不一定是试图解决这个错误，而是找到一种方法规避它。我已经尝试降级/运行LWJGL 2而不是/用LWJGL 3，这非常糟糕，而且我也尝试了几个不同的PNG解码器以获得我想要的东西，但我不能搞清楚。此外，我已经获得了＆＃34; LWJGL 3兼容的slick-util＆＃34;但它没有我需要的任何类/方法。如果有人可以为我修改我的代码或告诉我如何自己修复它，那就太可爱了。

这是错误：
