please help me, i've been trying to make the 'cash' variable go up and it wont budge, does anyone know how to fix this?







function love.load()
numberOne = 0
numberTwo = 0
numberThree = 0
cash = 0
timesSpun = 0
end

function love.update(dt)
if numberOne > 9 then
numberOne = 1
elseif numberTwo > 9 then
numberTwo = 1
elseif numberThree > 9 then
numberThree = 1
elseif numberOne == numberTwo == numberThree then
cash = cash + 1
end
end

function love.keypressed(key)
if key == "enter" then
timesSpun = timesSpun + 1
else
numberOne = numberOne + love.math.random(1, 10)
numberTwo = numberTwo + love.math.random(1, 10)
numberThree = numberThree + love.math.random(1, 10)
end

function love.draw()
love.graphics.print(cash, 10, 10)
love.graphics.print(numberOne, 200, 300)
love.graphics.print(numberTwo, 300, 300)
love.graphics.print(numberThree, 400, 300)
love.graphics.print("Press 'Enter' to Spin!", 400, 10)
end
end

Code: Select all

function love.load()
     numberOne = 0
     numberTwo = 0
     numberThree = 0
     cash = 0
     timesSpun = 0
end

function love.update(dt)
     if numberOne > 9 then
          numberOne = 1
     elseif numberTwo > 9 then
          numberTwo = 1
     elseif numberThree > 9 then
          numberThree = 1
     elseif numberOne == numberTwo == numberThree then
          cash = cash + 1
     end
end

function love.keypressed(key)
     if key == "enter" then
          timesSpun = timesSpun + 1
     else
          numberOne = numberOne + love.math.random(1, 10)
          numberTwo = numberTwo + love.math.random(1, 10)
          numberThree = numberThree + love.math.random(1, 10)
end

function love.draw()
     love.graphics.print(cash, 10, 10)
     love.graphics.print(numberOne, 200, 300)
     love.graphics.print(numberTwo, 300, 300)
     love.graphics.print(numberThree, 400, 300)
     love.graphics.print("Press 'Enter' to Spin!", 400, 10)
end
end

Please use [code]...[/code] tags for wrapping code. I've done it for you above.

The main problem is this line:

Code: Select all

     elseif numberOne == numberTwo == numberThree then

That works in Python, but not in almost every other language. Lua, like most other languages, calculates operands with the same priority from left to right (with exceptions, but == is not an exception). So that line is equivalent to:

Code: Select all

     elseif (numberOne == numberTwo) == numberThree then

That does not do what you want, because the == operator returns a boolean, so you're comparing a boolean to a number, which won't ever be true. To compare if all three are equal, you can use this instead:

Code: Select all

     elseif numberOne == numberTwo and numberTwo == numberThree then

That's not the only problem, though. In function love.keypressed, the `else` does not have a corresponding `end`, so Lua takes the next `end` (the one that you thought it would close the function) as closing the else. As a result, the function love.draw() is defined INSIDE love.keypressed. The correct way to write it is:

Code: Select all

     ...
     else
          numberOne = numberOne + love.math.random(1, 10)
          numberTwo = numberTwo + love.math.random(1, 10)
          numberThree = numberThree + love.math.random(1, 10)
     end -- ***** this is the `end` that you need to insert
end

and remove the second `end` at the end.

There will be more problems when those issues are fixed, but I leave them up to you
