I wanted to add a typewriter effect but I get an error.

Code:

-- EVILMANA.COM PSP LUA CODEBASE
-- www.evilmana.com/tutorials/codebase
-- Typewriter Effect for Text
-- SUBMITTED BY: dennis van den broek

-- Code : DS (dialogue system)
-- Autor: Dennis van den broek

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

-- initialise if the DS (dialogue system) should be called
DS_set = 0

-- strings used for the effect
DS_str = { }
DS_str[1] = "This is a typewriter machine test..."
DS_str[2] = "This code is a test which can be used freely,"
DS_str[3] = "in any type of game, credits are allways welcome"

-- temp string that stores the current to write string
write_str = ""
str_length = 0
-- counter for holding where on the string we are
i = 1
num = 1

-- sets the DS on or off
function init_DS(type)
        if type == 1 then
                DS_set = 1
        else
                DS_set = 0
                num = 1
        end
end

-- checks what string to write, function should be upgraded with detection of which
string to print
-- currently it's a simple placeholding code
function set_DS()
        if num > 3 then
                init_DS(0)
        end
       
        Typewriter(DS_str[num], 2, 10, 100)
end

-- the actual code, input the string you wanna print, and how many characters per
frame you wanna show up...
function Typewriter(str, speed, DSx, DSy)
        read_str = str
        str_length = string.len(read_str)
       
        if i <= str_length then
                i = i+speed
                write_str = string.sub(read_str, 1, i)

                screen:print(DSx, DSy, write_str, white)
        else
                screen:print(DSx, DSy, write_str, white)
                if pad:cross() and oldpad:cross() ~= pad:cross() then
                        i = 0
                        num = num + 1
                end
        end
end

-- main while loop
while true do
        pad = Controls.read()

        if pad:cross() and oldpad:cross() ~= pad:cross() then
                init_DS(1)
        end
       
        if DS_set == 1 then
                set_DS()
        end

        screen.waitVblankStart()
        screen.flip()

        screen:clear()
        oldpad = pad
end

---

how about you post the error... Why wouldnt you saying you need help?

And I dont have time to read through the code and see whats wrong, even with an the error, but I can say having any 'screen' calls after you flip the display buffer is pointless. remove the screen:clear, it has no effect.

I get this error.

Code:

---

Error: index.lua:38 /=/ expected near /to/

---

Well, go to line 38, see if there is something there that shouldnt be... Looks to me that the comment got brought out of the -- segment, making an error... Simply add '--' before 'string' on line 38.

And on all of the other lines where comments are.

Ok I got it to work. Now If I want to exit my program, do I just input

Code:

---

if pad:start() then
exit
