Question regarding GUI sliders
Hello - i want to add several GUI sliders to my program - inspired by
the slider tutorial. The problem is that i want each slider to perform different functionality - and there is no identification for each slider. Anyway to fix this? does a slider obj have maybe an identity function? Thanks, Dan |
2nd question - IS vertical slider possible?
Hi all,
As I am slowly learning the very basics, I would really like some help to know the following... is it possible to display a gui slider vertically? I have displayed one horizontally and after much fiddling around (I dont know python, still learning slowly) I managed to do what i want , i.e i wanted to display an object and scale it bigger and smaller with a slider with this code def myslider(obj, pos): bed.setScale( .01*pos, .01*pos, .01*pos ) viz.callback(viz.SLIDER_EVENT,myslider) However, can I add: 1) a vertical slider so that the object can be moved up and down? if so what would the code look like? 2) I wanted to use a live webcam as the background image. there is a tutorial that maps the webcam as a texture to a quad. Can the live webcam image just be mapped as the "background" just like you can clear the background to a basic color, can it be "cleared" to the webcam image? I tried unsuccessfully to map the webcam live image to the skydome, but that just distorts the webcam image :( Thanks in advance! |
The identity of a slider object is the object itself. Have a look at the docs for viz.SLIDER_EVENT, it explains how to determine which slider has changed. You can also use vizact.onslider for setting up callbacks for individual slider changes. Here is some sample code:
Code:
import viz |

slider.setEuler(0,0,90) Quote:

import viz |
Thank you for the code Farshizzo.
I do think I need to read a lot more! I was thinking adding a texture as background would be a one line code :-) I tried out your example and it does work, but I have no clue as to how to make the live camera appear as the backgorund. Simply substituting 'cam' in place of tex in the above example does not do it :( Regards |
P.s I just had to at least buy a Lite lisence while i keep asking so many questions.
So I did :) |
I replaced the ball texture with a webcam texture and it worked fine for me. Here is the code:
Code:
import viz |
:) works! I was adding an un nessary line.
Thanks farshizzo! |
