Variables inside Functions (Corona Lua)
I've searched everywhere for an answer on how to change a variable inside a function. I have tried many different solutions but none have worked so far.
My plan is to change a variable named 'stateRed' inside a function which is run when a button is pressed. When the function is run, the variables will change to 'READY'. I will then use this variable to run a separate chunk of code (the actual game). There are two of these buttons.
My code looks something like this:
function ReadyRed()
stateRed = 'READY'
stateBtnRed = widget.newButton
{
defaultFile = "ready_red.png",
overFile = "unready_red.png",
label = "Ready",
emboss = true,
onPress = unreadyStateRed,
}
stateBtnRed.rotation = 90; stateBtnRed.width = 90; stateBtnRed.height = 90; stateBtnRed.x = display.contentWidth / 2 - 170; stateBtnRed.y = display.contentHeight - 270
return stateRed
end
function UnreadyRed()
local stateRed = 'UNREADY'
stateBtnRed = widget.newButton
{
defaultFile = "unready_red.png",
overFile = "ready_red.png",
label = "Unready",
emboss = true,
onPress = readyStateRed,
}
stateBtnRed.rotation = 90; stateBtnRed.width = 90; stateBtnRed.height = 90; stateBtnRed.x = display.contentWidth / 2 - 170; stateBtnRed.y = display.contentHeight - 270
return stateRed
end
The code that starts the game looks like this:
if stateRed == 'READY' and stateBlue == 'Ready' then

In your code you defined two different variables named the samestateRed. One is global and second is local (it exists only inUnreadyRedfunction).

If variable stateRed is global then remove local keyword stand before variable name i.e.
function UnreadyRed()
stateRed = 'UNREADY'
...
end
Note:
- You probably don't need return
stateRedinReadyRedandUnreadyRedfunctions sincestateRedis global variable. - Use one notation style. I recommended you Camel Case notation
