Problems with LUA...

[Leon2342]

I cannotfor the life of me get this **** working...I need to have a menu system where each scene can have at the minimum 1 option that the user can select to switch to another scene, I got the menu all made but as soon as i go into the game, and hit x, nothing happens and it doesnt switch to the next scene, meaning it either is instantly switching back to the first scene or x isn't being detected, so I fixed that but whenever I press x now, the game spazzes out flashing between the two scenes I have for a few seconds before stopping on one of them, so I went back and cahnged things and now it starts with a black screen and after I press x it just flashes between the two scenes, what exactly am I doing wrong?

Here is the code I have

white = Color.new(255,255,255)
grey = Color.new(120,120,120)
black = Color.new(0,0,0)
foyer = Image.load("foyer.jpg")
frontyard = Image.load("frontyard.jpg")
oldpad = Controls.read()
gamestate = "front"
selector = { image = Image.createEmpty(145,15), x = 5,y = 180 }
selector.image:clear(grey)
function sceneFront()
screen:clear()
gamestate = "front"
pad = Controls.read()
screen:blit(0,0,frontyard)
screen:blit(selector.x,selector.y,selector.image)
screen:print(10,183,"Foyer",white)
end
function sceneFoyer()
screen:clear()
gamestate = "foyer"
pad = Controls.read()
screen:blit(0,0,foyer)
screen:blit(selector.x,selector.y,selector.image)
screen:print(10,183,"Front Yard",white)
end
while true do
pad = Controls.read()
if pad:cross() and oldpad:cross() ~= pad:cross() and gamestate == "foyer" then
sceneFront()
else if pad:cross() and oldpad:cross() ~= pad:cross() and gamestate == "front" then
sceneFoyer()
end
screen.flip()
oldpad = pad
end
end

hmm, Lua usually treats variables globally, unless you declare them with local.
You're updating "pad" in all the functions, try changing the name of them in each function and see if the problem still occurs.

not usre exactly what it is i did differently but i fixed it, code is now as follows

white = Color.new(255,255,255)
foyer = Image.load("foyer.jpg")
frontyard = Image.load("frontyard.jpg")
gamestate = "front"
function sceneFront()
screen:clear()
screen:blit(0,0,frontyard)
screen:print(5,180,"Go to Foyer",white)
end
function sceneFoyer()
screen:clear()
screen:blit(0,0,foyer)
screen:print(5,180,"Go to Front",white)
end

while true do
pad = Controls.read()
if gamestate == "front" then
sceneFront()
end
if gamestate == "foyer" then
sceneFoyer()
end
if pad:cross() and oldpad:cross() ~= pad:cross() and gamestate == "front" then
gamestate = "foyer"
elseif pad:cross() and oldpad:cross() ~= pad:cross() and gamestate == "foyer" then
gamestate = "front"
end
screen.flip()
oldpad = pad
end

Yeah, I guess it was the issue I mentioned, you removed the pad update from the other functions.

cool, so if i run into anymore issues with things is it alright to contact you directly through a message? I'm just working on a side project to see how much I am able to do with the thing I have set in my mind

You should indent your code, otherwise it will quickly become very hard to read.

Try changing this: oldpad:cross() ~= pad:cross() with this: not oldpad:cross()
