I am new to Lua so maybe I am missing something simple about object referencing.
I’m keeping an array of buttons so that I can fake a touch event when needed (the game involves showing a pattern). I have 12 buttons on screen but when I iterate through, only the 12th button ever shows the fake touch event. I have debugged to see if my array is populating (it is) and if the correct button was being triggered (it is). I am out of ideas…
-- array of buttons local lights = {}
This is my loop to populate the buttons and add them lights
-- iterating through an array to populate the buttons on screen for i=0,3 do for j=1,3 do tablePlace = tablePlace + 1 local xCoord = 0 local yCoord = 0 -- set the x coordinate if(j == 1) then xCoord = 60 elseif(j == 2) then xCoord = halfWidth else xCoord = display.contentWidth-60 end -- set the y coordinate yCoord = 85 + (i\*100) newLight = ui.newButton { defaultSrc = "button.png" , overSrc = "button-over.png" , x = xCoord, y = yCoord, defaultX = 45, defaultY = 45, overX = 45, overY = 45, onRelease = onReleaseLight, id = tablePlace } newLight.place = tostring( tablePlace ) myScreen:insert(newLight) -- add them to the array here lights[tablePlace] = newLight end end
The function iterates through the array and triggers the fake event through the timerListeners
-- Function to show the pattern (generate fake touch event) local function showLightPattern( group ) local delay = 1000 for i=1,level do print(tostring(i)..": #"..tostring(lightPattern[i])) local light = lights[lightPattern[i]] local turnOnLightClosure = function() return turnOnLightTimerListener( light ) end timer.performWithDelay( delay, turnOnLightClosure ) if(i \> 1) then local previousLight = lights[lightPattern[i-1]] local turnOffLightClosure = function() return turnOffLightTimerListener( previousLight ) end timer.performWithDelay( delay-500, turnOffLightClosure ) end -- Need to make the last light turn off! if(i == level) then local endOfLightsClosure = function() return turnOffLightTimerListener( light ) end timer.performWithDelay( delay+300, endOfLightsClosure ) end delay = delay + 800 end end
Here are the timerListeners, the :showOverSrc() and :hideOverSrc() are custom functions I created in ui.lua from the UI Library. They simply have the line
over.isVisible = true/false
in them. Like I said before the 12th button shows the turning on and off of the button but it should be jumping button to button. Setting the text works correctly and jumps from button to button
local function turnOnLightTimerListener( light ) print( "Turn on "..tostring( light.place )) light:showOverSrc() light:setText( tostring( light.place ) ) end local function turnOffLightTimerListener( previousLight ) print( "Turn off "..tostring( previousLight.place )) previousLight:hideOverSrc() previousLight:setText( "" ) end
