Hi Akram, try this:
pan-offset: 0.0
tilt-offset: 0.0
refresh: does [
print ["pan:" pan-offset "tilt:" tilt-offset]
]
control-window: center-face layout [
style hscroller scroller 200x20
across
label "pan" hscroller [pan-offset: face/data refresh] with
[data:
pan-offset]
return
label "tilt" hscroller [tilt-offset: face/data refresh] with
[data:
tilt-offset]
]
view/new control-window
do-events
The scroller/data is from 0.0 to 1.0 only, so if your pan and tilt values
range
outside these bounds, you will need to do map those values, eg:
pan-offset: face/data * 2
etc.
