The problem has mostly stopped. I guess it may have been a very
straightforward framerate issue? I get occasional hiccups now but nothing
like it was before. Here's the code I set up for an MWE. If I have the
issue again, I'll try to figure out more specifically what's causing it.
import pyglet
from pyglet.gl import *
from math import cos
window = pyglet.window.Window(1200, 800)
world_length = 3200
world_height = 3200
#set up viewpoint time dependence
view_x, view_y = 0, 0
wx = .67
wy = .723
time = 103.0
def update(dt):
global time, view_x, view_y
time += dt
view_x = world_length/4*(1.0-cos(wx*time))
view_y = world_length/4*(1.0-cos(wy*time))
pyglet.clock.schedule_interval(update, 1.0/60)
#set up openGL
glClearColor(0, 0, 0, 0)
glEnable(GL_BLEND)
glMatrixMode(GL_PROJECTION)
glLoadIdentity()
gluOrtho2D(-600, 600, -400, 400)
glMatrixMode(GL_MODELVIEW)
glLoadIdentity()
#create a bunch of tiles
tile = pyglet.image.load('background_image.png') #background
sprites = []
batch = pyglet.graphics.Batch()
for i in range(world_length/bottom.width+1):
for j in range(world_height/bottom.height+1):
sprites.append(pyglet.sprite.Sprite(tile, i*tile.width, j*tile.
height,
batch=batch))
def on_draw():
global view_x, view_y
window.clear()
glMatrixMode(GL_MODELVIEW)
gluLookAt(view_x, view_y, +1.0,
view_x, view_y, -1.0,
0.0, 1.0, 0.0)
batch.draw()
glLoadIdentity()
window.push_handlers(on_draw)
pyglet.app.run()
