Incrementing Integer

Solar2D Lua Language
#1

I have a event listener that listens for tap events on an object. When the event happens the score is suppose to increment by 1 (1,2,3,4,5,6,7,8,9 and so on). I also have a time that counts down to 0 from 60 and when score changes it doesn’t increase by 1 it seems to increase by the number that has been subtracted from the timer.

For example:

Tap at 59 seconds = 1 point

Tap st 50 seconds = 10 points

etc.

What puzzles me is when the object is tapped this is what SHOULD happen to the score.

score = score + 1 

which should increment only by 1 each time.

Whats going on here?

You placed your addEventListener code within a function that is being called every 1 second by the timer.  Change this:

local function timerDown() timeLimit = timeLimit-1 timeLeft.text = timeLimit if(timeLimit==0)then timeLeft.text = "Times Up" end circle:addEventListener("tap", circleTouched) circle:addEventListener("tap", countScore) end timer.performWithDelay(1000,timerDown,timeLimit)

To this:

local function timerDown() timeLimit = timeLimit-1 timeLeft.text = timeLimit if(timeLimit==0)then timeLeft.text = "Times Up" end end circle:addEventListener("tap", circleTouched) circle:addEventListener("tap", countScore) timer.performWithDelay(1000,timerDown,timeLimit)
#5

In doing that won’t the touch events work even though the time ran out?

#6

Yes.  That’s why it’s your job to remove them.  

local function timerDown() timeLimit = timeLimit-1 timeLeft.text = timeLimit if(timeLimit==0)then timeLeft.text = "Times Up" circle:removeEventListener("tap", circleTouched) circle:removeEventListener("tap", countScore) end end

ahhhh Ok I see now thanks!
