#1

How can i display on the screen the number of times i touched a button!!

#2

One way would be to make a variable called ‘numTouches’ for example, and set it equal to 0
Then in your touch code increase the touch count by 1 ( numTouches = numTouches + 1 ) and then just print it however you want.

**local numTouchesText = display.newText( " ", display.contentWidth/2, display.contentHeight/2, native.systemFont, 14 )

numTouchesText.text = ( "Number of touches: " … tostring( numTouches )**
)

when i touch the button:

error: …main.lua4: attempt to index global ‘event’ (a nil value)

  local numTouches = 0   local function numTouches (e)   if event.phase == "began" then       numTouches = numTouches+1         end  end       local button = display.newRect(0,0, 100, 100) button:addEventListener("touch", numTouches)            numTouchesText = display.newText("", display.contentWidth/2, display.contentHeight/2, native.sistemFont, 14)     numTouchesText.text=("Number of Touches".. tostring(numTouches)

Error says everything. In line 4 you try to access variable ‘event’ which is nowhere to find. You have ‘e’ as argument for listener function, not ‘event’. So you must check for e.phase value.
