Re: [Visualpython-users] help with moving camera

[Astan C. <st...@al...>]

Hi,
So now I've had abit of success. I can move the camera around using 
keyboard shortcuts but whenever the camera is rotated, the move up/down 
and strafe left/right becomes inconsistent. How do I update these? Im 
thinking I have to change the scene.forward somewhere, but to what value?
Thanks again for any advice.
Astan
Below is my code

from __future__ import division
from visual import *
import random

if __name__ == '__main__':

    # Set up window and sceen.
    scene = display()
    scene.fullscreen = 0
    scene.autocenter = 0
    scene.autoscale = 0
    scene.userzoom = 0
    scene.userspin = 0
    scene.ambient = 0
    outer = 10
    outer*= 2
    scene.range = (outer,outer,outer)

    rate(50)

    sunpos = [0,0,0]
    color = [ 3, 1.5, .75]
    sunradius = 2
    sun = sphere( pos=sunpos, radius=sunradius, color=color)

    while True:               
        if scene.kb.keys:
            s = scene.kb.getkey()
            angle = 0
            #move in / out
            if s == 'w' or s == 's':
                ray = 1
                if s == 's':
                    ray = -1
                scene.center = scene.center+scene.forward*ray/2.
            #strafe left / right
            if s == 'a' or s == 'd':
                move = vector(-0.5,0,0)
                if s == 'd':
                    move = vector(0.5,0,0)
                scene.center = scene.center+move
            #look left / right
            if s == 'left' or s == 'right':
                ray = 0
                angle = 0.6
                if s == 'right':

                newforward = rotate(scene.forward, axis=scene.up, 
angle=angle/10.)
                scene.center = 
scene.mouse.camera+newforward*mag(scene.center-scene.mouse.camera)
                scene.forward = newforward
                scene.center = scene.center+scene.forward*ray/2.
            #move up / down
            if s == 'f' or s == 'v':
                move = vector(0,-0.5,0)
                if s == 'v':

                scene.center = scene.center+move
