Rotate a quad around a centre point in OpenGL

Question

I'm making a 2D game. I want to be able to render a texture on the screen after rotating it a certain amount around a centre point. Basically this is for a level rotation around a player. The player position being the rotation point and the direction of the player as the angle. This code wont work:

def draw_texture(texture,offset,size,a,rounded,rotation,point):
    glMatrixMode(GL_MODELVIEW)
    glLoadIdentity() #Loads model matrix
    glColor4f(1,1,1,float(a)/255.0)
    glTranslatef(point[0],point[1],0)
    glRotatef(rotation,0,0,1)
    glBindTexture(GL_TEXTURE_2D, texture)
    if rounded == 0:
        glBegin(GL_QUADS)
        glTexCoord2f(0.0, 0.0)
        glVertex2i(*offset) #Top Left
        glTexCoord2f(0.0, 1.0)
        glVertex2i(offset[0],offset[1] + size[1]) #Bottom Left
        glTexCoord2f(1.0, 1.0)
        glVertex2i(offset[0] + size[0],offset[1] + size[1]) #Bottom, Right
        glTexCoord2f(1.0, 0.0)
        glVertex2i(offset[0] + size[0],offset[1]) #Top, Right
        glEnd()
    else:
        #Nothing important here
    glEnd()

Any way to get it working? Thank you.

Answer 1

try reversing

glTranslatef(point[0],point[1],0)

and

glRotatef(rotation,0,0,1)

you're translating to the player, but then rotating about the origin (not the player)

Answer 2

Unless you have a good reason to do otherwise, I'd leave the drawing code alone, and just change the camera angle. Probably the easiest way to do that is use gluLookAt. In your case, you'll apparently be looking at the player's position, and just change the "up direction", which is given in the last two parameters.
