Question

is there a touch and hold event in Corona sdk, If not then how to do that. for example. i want to increase the radius of a circle while holding anywhere on the screen, and without moving. how to do that. '

thanx

Answer 1

Try (as I know you can't change radius so I use xScale and yScale to increase circle)

local circle = display.newCircle(  display.contentCenterX, display.contentCenterY, 50 )
step = 0.02

local holding = false
local function enterFrameListener()
    if holding then
        -- Holding button
        circle.xScale = circle.xScale + step
        circle.yScale = circle.yScale + step
    else
        -- Not holding
        -- Code here
    end
end

local function touchHandler( event )
    if event.phase == "began" then
        Runtime:addEventListener( "enterFrame", enterFrameListener )
        holding = true  
    elseif event.phase == "ended" or event.phase == "moved" then
        holding = false
        Runtime:removeEventListener( "enterFrame", enterFrameListener )
    end
    return true
end

Runtime:addEventListener( "touch", touchHandler )
