Hi All,
I'm having trouble integrating this "grow controller" I wish to have a dot that you can pull outwards from the middle to resize, release then resize from it's current radius to a larger or smaller size.
I picture is worth a million words so here goes:
The tricky part is that I don't want it to reset itself to small on the second touch, if that makes sense...
would you recommend a resizable button or to just code it in a touch event handler?
Any pointers to get me started would be greatly appreciated!
Thanks
Alex

Thanks DarkConsoles!
That's very helpful and exactly what I envisioned for the initial growing. Now to figure out how to make it smaller again.
This will keep me busy over new years :)
Happy new year to all!
Alex

local cir_rd = 30
local circle_1 = nil
circle_1 = display.newCircle(200, 200, cir_rd )
function letsResizeNow(event)
--use event.x on screen to tell us how to resize RADIUS (use cir_rd * 2 to get 60 for diameter)
cir_rd = ((event.x - circle_1.x) + 60)
--remove old circle
circle_1:removeSelf()
--redraw new(SIZED) circle same x and y different radius
circle_1 = display.newCircle(200, 200, cir_rd)
--Just because we what to change the color and see resize works
circle_1:setFillColor(math.random (255), math.random (255),math.random (255))
end
Runtime:addEventListener( "touch", letsResizeNow )<code>
Have FUN!

@sharp1959, wow, its simple and awesome)
Just remember it is a Runtime Event
Runtime:addEventListener( "touch", letsResizeNow )
May have to play a litte to get circle touch event to work depending on what your looking for
Fantastic!
Thanks so much for your help!!!
Happy new year to all :)
Happy Newyear to you also, and BE safe!
Have Fun! :)
