Hi Karthi,
Here's a script I just wrote that does what you want. It displays a question with two choices. Use the joystick pad to select an option. The selected option will be colored red. Use the trigger button to make your choice.
Code:
import viz
import sid
CHECK_JOYSTICK_MOVE = 0
CHECK_JOYSTICK_CLICK = 1
HIGHLIGHT_COLOR = [1,0,0]
NONHIGHLIGHT_COLOR = [1,1,1]
viz.go()
Question = viz.add(viz.TEXT3D,'Is Vizard Awesome?',viz.SCREEN)
Question.translate(0.5,0.8)
Question.alignment(viz.TEXT_CENTER_CENTER)
Choices = ['Yes','No']
TextList = []
for x in range(0,len(Choices)):
text = viz.add(viz.TEXT3D,Choices[x],viz.SCREEN)
text.translate(0.3,0.6-(0.1*x))
if x == 0:
text.color(HIGHLIGHT_COLOR)
else:
text.color(NONHIGHLIGHT_COLOR)
TextList.append(text)
SelectedChoice = 0
def mytimer(num):
global SelectedChoice
if num == CHECK_JOYSTICK_MOVE:
y = sid.get()[1]
if y < -0.3:
TextList[SelectedChoice].color(NONHIGHLIGHT_COLOR)
SelectedChoice = (SelectedChoice + 1) % len(Choices)
TextList[SelectedChoice].color(HIGHLIGHT_COLOR)
viz.starttimer(CHECK_JOYSTICK_MOVE,0.5)
elif y > 0.3:
TextList[SelectedChoice].color(NONHIGHLIGHT_COLOR)
SelectedChoice = (SelectedChoice - 1) % len(Choices)
TextList[SelectedChoice].color(HIGHLIGHT_COLOR)
viz.starttimer(CHECK_JOYSTICK_MOVE,0.5)
else:
viz.starttimer(CHECK_JOYSTICK_MOVE,0.01)
elif num == CHECK_JOYSTICK_CLICK:
if sid.buttons() & 1:
if SelectedChoice == 0:
print "You have good taste"
else:
print "I just plain don't like you"
viz.starttimer(CHECK_JOYSTICK_CLICK,0.5)
else:
viz.starttimer(CHECK_JOYSTICK_CLICK,0.01)
viz.callback(viz.TIMER_EVENT,mytimer)
viz.starttimer(CHECK_JOYSTICK_MOVE,0.01)
viz.starttimer(CHECK_JOYSTICK_CLICK,0.01)
