coordinates problem

[Crazralfrill]

Hi,

I'm migrating my game to rabbyt+pygame to rabbyt+pyglet.

With pygame, my origin were in the top left corner.

But when I use pyglet, my origin is at the bottom left corner.

I used this :
viewport = (800, 600)
projection = (0, 0, 800, 600)
rabbyt.set_viewport(viewport, projection=projection)


Is there a problem with set_viewport projection with pyglet? Or maybe
I don't understand how it works.


And an other subject : what fast gui framework do you suggest me to
use with rabbyt?

Thanks.

Underneath, rabbyt.set_viewport just calls the opengl function
glViewport. My guess is that pyglet is also calling glViewport at a
later point, overwriting the values set when you called
rabbyt.set_viewport.

Try calling rabbyt.set_viewport at the beginning of each frame.

Thanks! You were right! Unfortunately, changing the viewport mess with
pyglet rendering, and I don't want to change the viewport multiple
times to handle that, so I decided to stick with pyglet coordinates
and remake somes parts of my work.

But thanks again anyway.
