Hi there,
Having a simple issue here. I am trying to get a + and - button to either + or - a set value.
This is how I have coded it:
local qty = 0
local number = display.newText (qty, 50, 50, native, 30)
number.x = display.contentWidth/2
number.y = display.contentHeight/2
local plusButton = display.newImage (“plusButton.png”)
plusButton.x = display.contentWidth/2
plusButton.y = display.contentHeight/2-150
local minusButton = display.newImage (“minusButton.png”)
minusButton.x = display.contentWidth/2
minusButton.y = display.contentHeight/2+150
local function plusButtonTap (event)
qty = qty+1
end
local function minusButtonTap (event)
qty = qty-1
end
plusButton:addEventListener(“tap”,plusButtonTap)
minusButton:addEventListener("tap"minusButtonTap)
When I try to use this code, it does not add or subtract 1 as I have tried to get it to do in the application.
Have I missed something vital out, or do I need to se qty.tonumber? <- when I tried that it bugged out…
Thanks
Daine
