Lua Programming Help Thread

whats the code?sounds like you have too many or not enough "end" statments

also I was messing around with the code for the analog stick so i figured id post it here incase someone learning how to use the analog stick wants to use it

Code:

---

white = Color.new(255, 255, 255)

while true do
screen:clear()
        pad = Controls.read()
        analogX = pad:analogX()
        analogY = pad:analogY()
        if pad:start() then
                break
        end

--Up/Down/Left/Right
                --Right
        if analogX > 32 and analogY > -40 and analogY < 40 then
                screen:print(200, 100, "Right", white)
        end
                --Left
        if analogX < -32 and analogY > -40 and analogY < 40 then
                screen:print(200, 100, "Left", white)
        end
                --Down
        if analogY > 32 and analogX < 40 and analogX > -40 then
                screen:print(200, 100, "Down", white)
        end
                --Up
        if analogY < -32 and analogX < 40 and analogX >-40 then
                screen:print(200, 100, "Up", white)
        end
                --Center
        if analogY > -32 and analogY <32 and analogX < 32 and analogX > -32 then
                screen:print(200, 100, "Center", white)
        end

--Diagnals
                --Up/Right
        if analogY < -32 and analogX > 40 then
                screen:print(200, 100, "Up and Right", white)
        end
                --Up/Left
        if analogY < -32 and analogX < -40 then
                screen:print(200, 100, "Up and Left", white)
        end
                --Down/Right
        if analogY > 32 and analogX > 40 then
                screen:print(200, 100, "Down and Right", white)
        end
                --Down/Left
        if analogY > 32 and analogX < -40 then
                screen:print(200, 100, "Down and Left", white)
        end




screen.flip()
end

yeah thanks! i appreciate it!

Dont make your games online. Period. Right now, LUA only supports TCP. TCP is slow, all/most online games use UDP because its much faster. I got a TCP server on my computer to talk to my PSP as a test for netlib. It was wasy too slow (although much faster than the current netlib.)

If I can ever get UDP with netlib, making an online game is a good idea.

However, if I continue to devolop netlib with TCP, it would be useful for things like online scores and stuff that you send once. Right now, netlib has to connect every time you want to send data, and failing to connect and getting stuck in luaplayer is common.

(And to the person who said you need netlib to make an online game, you dont. You use the Wlan. functions)

could some1 tell me wat is wrong with my end statements? thanks!

BTW- if u find anything else wrong feel free to say! lol

you have too many of them,,
you dont need an end after screenflip, or print

EDIT, you also have an extra while true do statement that you dont need,,

To check if your ends are correct download NotePad++
itll connect everything, and colour the reserved words,it perfect

try taking away all the screenflips, except the one at the very end

ohh, and you spelled screenflip wrong on your second last statement
(you put screenfilp)
