Hello,
I'm new user of pyglet or OpenGL components and i have a question about
opacity/transparency about drawing objects. With this example code, i wrote
a rectangle:
# coding: utf-8
import pyglet
window = pyglet.window.Window()
vertexes = [(208, 41), (208, 266), (514, 266), (514, 41)]
@window.event
def on_draw():
window.clear()
pyglet.gl.glColor3ub(125, 255, 23)
pyglet.gl.glBegin(pyglet.gl.GL_QUADS)
pyglet.gl.glVertex3f(vertexes[0][0], vertexes[0][1], 0)
pyglet.gl.glVertex3f(vertexes[1][0], vertexes[1][1], 0)
pyglet.gl.glVertex3f(vertexes[2][0], vertexes[2][1], 0)
pyglet.gl.glVertex3f(vertexes[3][0], vertexes[3][1], 0)
pyglet.gl.glEnd()
pyglet.app.run()
But i don't know how change it's opacity. How to do that ?
Regards,
Bastien.
