Game scoring development?

//How am i able to create a scoring number here? the situation is the function questiongen() is use to add 2 numbers and the function //called checkAnswer() is use to check if the answer is correct or wrong. my goal here is to create a scoring number in which if the answer is correct //the scoretxt = 0 will be added + 1 and if the answer is wrong it will stay just the same. function questionGen() local questionVar1 = display.newImage("ygSquare.png", 150, 500); local var1 = math.random(1,9) local var1Display =display.newText(var1, 200, 500, native.systemFont, 200) questionVar1.width = 200 questionVar1.height = 200 questionVar1.x = 350 questionVar1.y = 500 var1Display.x = 350 var1Display.y = 500 var1Display:setTextColor("#000000") local questionVar2 = display.newImage("blueSquare.png", 150, 500); local var2 = math.random(1,9) local var2Display = display.newText(var2, 200, 500, native.systemFont, 200) questionVar2.width = 200 questionVar2.height = 200 questionVar2.x = 700 questionVar2.y = 500 var2Display.x = 700 var2Display.y = 500 var2Display:setTextColor("#000000") local operator = " + " local operatorDisplay = display.newText(operator, 400, 500, native.systemFont, 200) operatorDisplay:setTextColor("#000000") local varAnswer = var1 + var2 return varAnswer end function checkAnswer(event) if(#theAnswer == questionGen()) then instructionsText.text = "Correct!"; instructionsText:toFront() generateBalls() for i=1, allBallsGroup.numChildren do display.remove(allBallsGroup[1]) end else instructionsText.text = "Incorrect!"; instructionsText:toFront() generateBalls() for i=1, allBallsGroup.numChildren do display.remove(allBallsGroup[1]) end end end function addscore() local score = addscoreText.text countDownText.text = score if(#theAnswer == questionGen()) then score = score + 1 else score = score ~+ 1 end end

I would make score local to the module, not local to the function.

Remove lines 66 and 67 they are not needed.

after line 65 (score = score + 1) insert this line

addscoreText.text = score

the code about countDownText.text = score is a little confusing. I cannot see all the code, so I am not sure why you are adding score to countDownText. I can guess, but it is not relevant to your question as I read it.

I guess maybe the countDownText is how many questions were asked or maybe failed(I am just guessing). I would try to keep score and countDown separate. I apologize if I have guessed wrong here, but without more code I can only guess in an effort to help.

good luck

Line 63 supposed to be

addscoreText.text= score

and yes sir bob i already added that line but the score is still 0 and won’t add up… and yes the code is not complete i removed other functions that is not related on my scoring…

here is my complete code

You need to put that addscoreText.text= score below where you’ve added 1 to the score – if it’s really at line 63 then you’re pulling score out, then putting it right back in, unchanged.
