无法获取属性位置pyglet

问题描述

此代码不允许我使用它

 position_loc = glGetAttribLocation(shader,"position")
 color_loc = glGetAttribLocation(shader,"color")

附近的完整代码

 shader = OpenGL.GL.shaders.compileProgram(OpenGL.GL.shaders.compileShader(self.vertex_shader_source,GL_VERTEX_SHADER),OpenGL.GL.shaders.compileShader(self.fragment_shader_source,GL_FRAGMENT_SHADER))
                                              
    position_loc = glGetAttribLocation(shader,"position")
    color_loc = glGetAttribLocation(shader,"color")
                    
                                              
    gluseProgram(shader)
    
    vbo = gluint(0)
    glGenBuffers(1,vbo)
    
    glBindBuffer(GL_ARRAY_BUFFER,vbo)
    glBufferData(GL_ARRAY_BUFFER,72,(GLfloat * len(self.triangle))(* self.triangle),GL_STATIC_DRAW)
    
    glVertexAttribPointer(0,3,GL_FLOAT,GL_FALSE,24,ctypes.c_void_p(0))
    glEnabLevertexAttribArray(0)
    
    glVertexAttribPointer(1,ctypes.c_void_p(12))
    glEnabLevertexAttribArray(1)

这是除着色器之外的所有代码，这是我的另一个问题。如果我没有得到位置，它工作正常，但有人告诉我我需要。如果你能帮助我理解为什么它不起作用那会很棒

解决方法

name 参数需要是 Bytes literal (bytesprefix b) 而不是字符串：

position_loc = glGetAttribLocation(shader,'position')
color_loc = glGetAttribLocation(shader,'color')

position_loc = glGetAttribLocation(shader,b'position')
color_loc = glGetAttribLocation(shader,b'color')
