Getting Started Newbie Questions
#1

how do i make a delay on a button

#2

This code will add an event listener to “myButton” and after one second (1000 milliseconds) “myFunction()” will be called.

myButton:addEventListener( "tap", function() timer.performWithDelay( 1000, myFunction ) end )
#3

can you give me the code with a button to because i can’t seem to get it to work

#4 
--------------------------------------------------------------------------------- -- -- main.lua -- --------------------------------------------------------------------------------- -- hide the status bar display.setStatusBar( display.HiddenStatusBar ) local function onTapButton( event ) print("Immediately we are in 'onTapButton'!") local function delayedPrint() print("But I come a little bit later ...") end timer.performWithDelay( 1000, delayedPrint ) end local myButton = display.newRect( 100, 100, 100, 100 ) myButton:addEventListener( "tap", onTapButton )
#5

i need to prevent spam of a button would this work

#6

My previous code will not work for that. It will only delay before the other function gets called.

This code checks if the button is being pressed and stores a time value. If the last_successful_tap was three seconds ago it will proceed, otherwise it will print “Stop spamming!” in the console:

local last\_successful\_tap = nil local function onTapButton() if last\_successful\_tap == nil then last\_successful\_tap = os.time() end if os.time() - last\_successful\_tap \> 3 then last\_successful\_tap = os.time() print("Ok, let's proceed!") else print("Stop spamming!") end end local myButton = display.newRect( 100, 100, 100, 100 ) myButton:addEventListener( "tap", onTapButton )
#7

Also you could include how many times the button have been pressed by the user so for example the user can only tap the button every 2 seconds but also only 5 times per second or something like that.

thank you so much

It really helps to have a better description of what you want to do. “I want a delay on a button” could be for any reason and provoke a variety of responses.
