我正在尝试在python中创建一个过剩的窗口,并具有以下代码:

glutInit()
    glutInitWindowSize(windowWidth, windowHeight)
    glutInitWindowPosition(int(centreX - windowWidth/2), int(centreY - windowHeight/2))
    glutCreateWindow("MyWindow")
    glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB | GLUT_DEPTH)
    glutDisplayFunc(displayFun)
    glutIdleFunc(animateFun)
    glutKeyboardFunc(keyboardFun)
    glutPassiveMotionFunc(mouseFun)

    glutReshapeFunc(reshapeFun)
    initFun()
    #loadTextures()
    glutMainLoop()

我在'glutCreateWindow'一行中收到错误说:

Traceback (most recent call last):
  File "F:\MyProject\main.py", line 301, in <module>
    glutCreateWindow("MyWindow")
  File "C:\Python34\lib\site-packages\OpenGL\GLUT\special.py", line 73, in glutCreateWindow
    return __glutCreateWindowWithExit(title, _exitfunc)
ctypes.ArgumentError: argument 1: <class 'TypeError'>: wrong type

有关此函数的文档指定

int glutCreateWindow(char *name);

简而言之，有什么方法可以检测JavaScript中的其他鼠标按钮按下情况吗？其余的鼠标输入未对此进行记录，因此我想它不在标准实现中。

是否有其他方法（例如库）可以启用额外的鼠标按钮？

我遇到了一个错误，即go不能正确解决供应商的程序包；在macOS High Sierra 10.13.6上。我将使用github.com/gorilla/mux作为示例包

我正在导入软件包

运行时：

go build -o out main.go

对于供应商中的每个包装，我都会收到以下错误

我正在尝试使用tiny_obj_loader将其加载.obj到我的程序中。我有以下使用该库的代码：

void LoadModel(vector<Shape *> &scene, const char *path) {
  attrib_t attrib;
  vector<shape_t> shapes;
  vector<material_t> materials;
  std::string error;
  bool ret = tinyobj::LoadObj(
    &attrib,
    &shapes,
    &materials,
    &error,
    path
  );
  ... // Do stuff with the returned data

然而，这给了我以下链接器错误：

Build/skeleton.o: In function `LoadModel(std::vector<Shape*, 
std::allocator<Shape*> >&, char const*)':
skeleton.cpp:(.text+0x3025): undefined reference to `tinyobj::LoadObj(tinyobj::attrib_t*, std::vector<tinyobj::shape_t, std::allocator<tinyobj::shape_t> >*, std::vector<tinyobj::material_t, std::allocator<tinyobj::material_t> >*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >*, char const*, char const*, bool)'

我正在尝试使用lwjgl在屏幕上渲染纹理矩形.我已经注册了纹理并加载了它们.我正在尝试编写一个方法,只使用纹理的指定区域来应用于矩形,这将允许使用spritesheets.我有这个代码来做到这一点:

public static void drawTexturedRectangle(int x, int y, int width,
        int height, int textureX, int textureY, int textureWidth,
        int textureHeight, Texture texture) {

    System.out.println("Drawing tr:"); //console output to check input
    System.out.println("  -input:");
    System.out.println("    -x: " + x);
    System.out.println("    -y: " + y);
    System.out.println("    -width: " + width);
    System.out.println("    -height: " + height);
    System.out.println("    -tex-x: " + textureX);
    System.out.println("    -tex-y: " + textureY);
    System.out.println("    -tex-width: " + textureWidth);
    System.out.println("    -tex-height: " + textureHeight);

    GL11.glBindTexture(GL11.GL_TEXTURE_2D, texture.getId());
    GL11.glBegin(GL11.GL_QUADS);
