在 pygame python 中的第二个和第三个立方体上插入其他图像

Question

对不起，我想问一些我被困住的事情。我有 3 个立方体来代表每个图像，如下所示 ，但是当我声明其他图像时，例如
textureSurface = pygame.image.load('images1.bmp', 'images2.bmp', 'images3.bmp') 图像仍然加载相同的图片，我已经尝试过 self.id 但我无法在我的代码中使用它，有人可以帮忙吗？谢谢。 这是我到目前为止已经尝试过的代码：

#import

     glViewport(0,0,display[0],display[1])
     gluPerspective(45, display[0]/display[1],0.1,50.0)
     loadTexture()
     
def loadTexture():
    textureSurface = pygame.image.load('image1.bmp', 'iamges2.bmp', 'iamges3.bmp')

    textureData = pygame.image.tostring(textureSurface, "RGBA", 1)
    width = textureSurface.get_width()
    height = textureSurface.get_height()

    glEnable(GL_TEXTURE_2D)
    texid = glGenTextures(1)

    glBindTexture(GL_TEXTURE_2D, texid)
    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, textureData)

Answer 1

pygame.image.load

仅加载 1 张图像。如果要使用多个纹理，则必须为每个图像创建单独的纹理对象。在绘制四边形之前立即绑定纹理。

编写一个加载 1 个图像并创建 1 个纹理对象的函数：

def loadTexture(imagename):
    textureSurface = pygame.image.load(imagename)

    # [...] rest of your code

    return texid

将纹理对象存储在全局命名空间中的数组中（参见

global

声明）：

texture_objects = []

def initialitation():
     global texture_objects 

     glClearColor(1.0, 1.0, 1.0, 1.0)   #Warna latar belakang putih
     glViewport(0,0,display[0],display[1])
     gluPerspective(45, display[0]/display[1],0.1,50.0)

     texture_objects.append(loadTexture('image1.bmp'))
     texture_objects.append(loadTexture('image2.bmp'))
     texture_objects.append(loadTexture('image3.bmp'))

在绘制四边形之前，先绑定你想要的纹理对象。举个例子：

def cube_image(lines=False):
    if lines:
        glDisable(GL_TEXTURE_2D)

        glBegin(GL_LINES)
        for edge in edges:
            glColor3fv((1, 1, 1))
            for vertex in edge:
                glVertex3fv(vertices[vertex])
        glEnd()

    else:
        glEnable(GL_TEXTURE_2D)

        #front
        glBindTexture(GL_TEXTURE_2D, texture_objects[0])
        glBegin(GL_QUADS)
        glTexCoord2f(0.0, 1.0); glVertex3f(-0.5, -0.5,  0.5);
        glTexCoord2f(1.0, 1.0); glVertex3f( 0.5, -0.5,  0.5);
        glTexCoord2f(1.0, 0.0); glVertex3f( 0.5,  0.5,  0.5);
        glTexCoord2f(0.0, 0.0); glVertex3f(-0.5,  0.5,  0.5);
        glEnd();
        
        #back
        glBindTexture(GL_TEXTURE_2D, texture_objects[1])
        glBegin(GL_QUADS)
        glTexCoord2f(0.0, 1.0); glVertex3f(-0.5, -0.5, -0.5);
        glTexCoord2f(1.0, 1.0); glVertex3f(-0.5,  0.5, -0.5);
        glTexCoord2f(1.0, 0.0); glVertex3f( 0.5,  0.5, -0.5);
        glTexCoord2f(0.0, 0.0); glVertex3f( 0.5, -0.5, -0.5);
        glEnd();
        
        #left
        glBindTexture(GL_TEXTURE_2D, texture_objects[2])
        glBegin(GL_QUADS)
        glTexCoord2f(0.0, 1.0); glVertex3f(-0.5, -0.5,  0.5);
        glTexCoord2f(1.0, 1.0); glVertex3f(-0.5,  0.5,  0.5);
        glTexCoord2f(1.0, 0.0); glVertex3f(-0.5,  0.5, -0.5);
        glTexCoord2f(0.0, 0.0); glVertex3f(-0.5, -0.5, -0.5);
        glEnd();
        
        #right
        glBindTexture(GL_TEXTURE_2D, texture_objects[0])
        glBegin(GL_QUADS)
        glTexCoord2f(0.0, 1.0); glVertex3f( 0.5, -0.5, -0.5);
