[Visualpython-users] using arrows in a class

[Richard C. <ax...@ch...>]

hi

okay i have a file called pp.py that has a class def in it

class _test:

	def __init__(self):
		self.arrow1 = arrow(...
		self.arrow2 = arrow(...

	def move(self, step):
		self.arrow1.pos.x = self.arrow1.pos.x + step
		self.arrow2.pos.x = self.arrow2.pos.x + step


now back in another file in the same directory i have

import pp

#now i create instances of the class like this
s1 = pp._test
s2 = pp._test


#now i have a while loop
while 1==1:
	s1.move(step=-2)
	s2.move(step=2)

now the problem i am having is that it is only showing s2's arrows, throwing
in some print statements in between sections of code sometimes i can get it
so that s1 arrows you see for a momentum, like flickering but a mostly not
displayed. like 10 seconds you dont see s1 and then for a second you do
where as s2 you see all the time, it seems almost as if s1 and s2 are
sharing the same arrows.

How do i stop this from happening, how do i get s1 and s2 to be displayed
together/ solid not flicker how it does. what am i doing wrong.


Thank you for any help

Can you flesh this out to make a complete, reproducible example?  This
one has syntax errors such that it is not completely clear what you are
trying to demonstrate.

To further elaborate on Jonathan's request, for example:
s = pp._test
does not create an instance of the _test class, but
s = pp._test() # note parentheses
does -- at least as your example defines this class.

The following test routine works for me. Note that in your note you 
wrote "s1 = pp._test" which should be "s1 = pp._test()". If this example 
doesn't address your problem, please submit a full test routine. I 
couldn't reproduce the behavior you describe.

from visual import *

class _test:
     def __init__(self):
         self.arrow1 = arrow(pos=(0,0,0), axis=(1,0,0), color=color.red)
         self.arrow2 = arrow(pos=(0,0,0), axis=(0,1,0), color=color.cyan)

     def move(self, step):
         self.arrow1.pos.x = self.arrow1.pos.x + step
         self.arrow2.pos.x = self.arrow2.pos.x + step

if __name__ == '__main__': # for testing the module
     #now i create instances of the class like this
     s1 = _test()
     s2 = _test()

     ###now i have a while loop
     while 1==1:
         rate(100)
         s1.move(step=-0.01)
         s2.move(step=0.01)
