我正在制作一个基于瓷砖的游戏，瓷砖的纹理是 16x16。每当我尝试加载纹理以便可以渲染它时，我都会收到此错误： 

java.io.IOException: Attempt to allocate a texture to big for the current hardware
at org.newdawn.slick.opengl.InternalTextureLoader.getTexture(InternalTextureLoader.java:292)
at org.newdawn.slick.opengl.InternalTextureLoader.getTexture(InternalTextureLoader.java:231)

at main.Draw.drawMap(Draw.java:284)
at main.Draw.render(Draw.java:324)
at main.LaunchWindow.main(LaunchWindow.java:65)

现在，我知道我的 gpu 可以处理它，因为它是 1GB 卡。

我跑了

GL11.glGetInteger(GL11.GL_MAX_TEXTURE_SIZE)

并得到 16384。

这是加载纹理的代码：

public void loadTexture(String a){
    try {
        texture = TextureLoader.getTexture("PNG", ResourceLoader.getResourceAsStream(a));
        System.out.println(texture.getTextureRef());

    } catch (IOException e) {
        e.printStackTrace();
    }
}

需要渲染时调用的代码：

public void drawMap(Map b){
    Color.white.bind();
    glBegin(GL_QUADS);

    b.divideMap(10);
    Tile[][] t = b.makeMap(b.getK());

    for(int y = 0; y < b.tiles.length; y++){
        for(int x = 0; x < b.tiles[y].length; x++){
            Texture a;
            t[y][x].loadTexture(t[y][x].getLocation());
            a = t[y][x].getTexture();
            System.out.println(a.getTextureRef());
            a.bind();
            glTexCoord2f(0,0);
            glVertex2f(x,y);
            glTexCoord2f(1,0);
            glVertex2f(x + a.getWidth(), y);
            glTexCoord2f(1,1);
            glVertex2f(x + a.getWidth(), y +  a.getHeight());
            glTexCoord2f(0,1);
            glVertex2f(x, y +  a.getHeight());
        }
    }

    glEnd();
}

不知道框架，但从代码中我看到你每帧都加载所有纹理并且从不释放它们。几帧后，你的内存不足。
