In a nutshell, I am working on a widget that consists of a wheel with
buttons. Currently I've just manually calculated out where 8 buttons go,
and
it works well, but I am trying to set it up with a user definable number
of
buttons contained in array "mData."
Need help checking my math (and LCB syntax.) I took out some of the
syntax
like setting paints and some other fluff, this is just calculating the
positions of each circle.
-- tBigRad is the radius of the main circle across the widget
if my width > my height then
put my height/2 into tBigRad
else
put my width/2 into tBigRad
end if
-- tLilRad is the radius of each small button around the edge
put tBigRad/4 into tLilRad
-- finding the coordinates of the center of the main circle
put my width/2 into tBigX
put my height/2 into tBigY
put point [(my width/2),(my height/2)] into tCenter
fill circle path centered at tCenter with radius tBigRad on this
canvas
-- create an "inner circle" by subtracting the radius of a button
from
the radius of the main circle
put tBigRad - tLilRad into tInnerRad
-- calculate angle in radians from the for the center of each button
put (the number of elements in mData)/(2 * pi()) into tButtonAngles
repeat with tButtonNumber from 1 up to the number of elements in
mData
put tInnerRad * (tButtonNumber-1 * tButtonAngles) into tAngle
put tBigX * cos(tAngle * pi()) into tButtonX
put tBigY * sin(tAngle * pi()) into tButtonY
put point [tButtonX, tButtonY] into tButtonCenter
fill circle path centered at tButtonCenter with radius tLilRad on
this
canvas
end repeat
