Hey guys,
I'm trying to use the 2d drawing primitives written by Flávio to
render in the 2d portion of a 3d game. Here's the code I'm trying to
call:
-->8--- snippy snippy -->8---
from pyglet.gl import *
from primitives import Circle, Line
CENTER = (150, 150)
class HUD:
def __init__(self, center=CENTER):
self.reticle = Reticle(center)
self.active = True
def draw(self):
if self.active:
self.reticle.draw()
class Reticle:
def __init__(self, position=CENTER, color=(0, 1, 0, 1)):
self.color = color
self.position = position
self.parts = []
self.lines = [
((position[0], position[1]-4), (position[0], position[1]-12)),
((position[0], position[1]+4), (position[0], position[1]+12)),
((position[0]-4, position[1]), (position[0]-12, position[1])),
((position[0]+4, position[1]), (position[0]+12, position[1])),
]
self.parts.append(
Circle(self.position[0], self.position[1], width=10, stroke=0.5,
style=GLU_LINE, color=self.color))
for line in self.lines:
print line
self.parts.append(
Line(a=line[0], b=line[1], stroke=1, color=self.color))
def draw(self):
for part in self.parts:
part.render()
if __name__ == '__main__':
from pyglet import window
win = window.Window()
hud = HUD((200, 200))
while not win.has_exit:
win.dispatch_events()
win.clear()
hud.draw()
win.flip()
This works fine if I call it directly, but doesn't seem to display at
all when I call it in my game between these two methods (which is
similar to the stuff in the Turret Command demo):
def mode2d(self):
glLoadIdentity()
glPushAttrib(GL_ENABLE_BIT)
glEnable(GL_TEXTURE_2D)
glEnable(GL_BLEND)
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)
glDisable(GL_LIGHTING)
glDisable(GL_DEPTH_TEST)
glMatrixMode(GL_PROJECTION)
glPushMatrix()
glLoadIdentity()
glOrtho(0, 1024, 0, 768, -1, 1)
glMatrixMode(GL_MODELVIEW)
def end_mode2d(self):
glMatrixMode(GL_PROJECTION)
glPopMatrix()
glMatrixMode(GL_MODELVIEW)
glPopAttrib()
Any idea what I'm doing wrong? Everything else seems to be displaying
fine (the 3d world, the blits into the 2d part, etc).
Thanks,
--Patrick.
