Yes there is a way, what do you think LUA Player is? Its a luaplayer ELF file, told to load the system.lua file with the luaplayer.elf in the Eboot. Meaning, either get the LUA Player Source and change it from loading system.lua to yours. Then just complie it up and your set, but you need the envirorment set up. Or just take the Lua Windows eboot, and swap the lua script with yours, and edit the % folder eboot to your liking, meaning image, sound, etc.
What the heck is wrong with my code?!
It says that file is a nil value when i trying to write, but it's not!
It wrote the file before, but i changed a thing that shouldent matter at all.
Then it don't reads from "text.txt".
Please help me out!
Code:----Write FUNCTION
function Write(filename,variabel)
file = io.open(filename,"w")
file:write(variabel)
file:close()
end
----Read FUNCTION
function Read(filename,variabel)
file = io.open(filename,"r")
variabel = file:read()
file:close()
end
----Write
if pad:square() then
Write("text.txt",Name)
end
----Read
if pad:cross() then
Read("text.txt",Name)
end
I think i know your problem. Your trying to write/read strings from/to a file. Well I belive you have to put " " around the string you plan on writing, or the text your writng to the file in lamen terms. Like when using screen: print(), you put the words/text in " ". screen: print("Hello"). This may be the problem because in C, you cant just write to a file the words Hello World as plain as that. You must either have a buffer for the string to be held in, or just write it out without using any variables that are being chagned alot.
fwrite(FILE*, Hello World); // <------DOESNT WORK
fwrite(FILE*, "Hello World"); // <-----DOES WORK
If my structure of the fwrite function is correct, then ya, that will work^.
Basically, I dont know if LUA does this or not, but I think you have to either have a buffer/array with the text you want/string in it, then write that to a file.
Oh and your having a problem with reading from afile. Your problem is probably that the 'variabel' thing that you replace, is not a buffer, or an array.
So to fix that problem, try making the word Name, a character array.
Name[]="" --Not sure you need these...
maybe you could do this without a problem?
Name[255]
Im not sure if LUA uses allocating memory... But w/e, maybe. Thats what the 255 is for, that means that this Name buffer can hold up to 255 bytes/characters. (I believe characters, Im not 100% sures ince its in the morning)
Then go and do your read function. This should, in your functions process, when callin variabel = file:read(), your actually going to be calling, if using Name array/buffer, Name = file:read(). That will put whatever is in the file your reading from, into the Name array/buffer, and its ready to be printed to the screen, edited, copied, etc.
I dont think any of this helps since Im not frequently coding in LUA, but maybe, tell me if so.
I got the writing fully working now but I
still can't get it read at all.
What is the Name thing your using, is it a variable? when reading from a file, feeed what you read into an array/buffer. meaning make name, Name[255]
See what happens, or just tell me what Name is.

dint understand nothing what to do. if you make a tutorial. that will be really nice
but though, it gives a error when i try to make an eboot with luaplayer source
in my game i am try ing to load numbered images
heres my code:
Code:for a = 1,1362 do
local a
image[a]=Image.load("image"..a".jpeg")
end
And are you getting an error? Cause i think your missing something in there too. Arrays count0 as a place holder, so set a = 0 if your having trouble blitting thos images or w/e.
Unless the LUA for do loop cannot have anything other than 1 there, since it increases by that number or something? I dunno, not really frequent i n LUA.
Ok, go and download hte app PSP Windows, its in LUA. Take the EBOOT, and rename your script to matach theres and the structure of where it is and such. Then just use kxploit to make an icon thing, then edit its picture and junk.Zitat:

The variable "Name" is just a simple string like this:
Code:Name = "Text"
Hello all, can someone help me with this code? For some reason, when I try to run it on the PC, it creates a luaplayer.exe.stackdump file. The code:
When the stackdump is opened with notepad, its:Code:
red=Color.new(255,0,0)
green=Color.new(0,255,0)
blue=Color.new(0,0,255)
white=Color.new(255,255,255)
duh=Image.load("duh.png")
counter=Timer.new()
counter:start()
screen:blit(50,50,"duh.png")
while true do
pad=Controls.read()
if pad:up() then
duh.y=duh.y + 2
end
if pad:down() then
duh.y=duh.y - 2
end
if pad:right() then
duh.x=duh.x + 2
end
if pad:left() then
duh.x=duh.x - 2
end
currentTime=counter:time()
screen:clear(blue)
screen:print(10,10,"Counter Time: " .. currentTime, white)
if currentTime > 2500 and currentTime < 5000 then
screen:clear(red)
end
if currentTime > 5001 then
counter:reset(0)
counter:start()
end
screen.waitVblankStart()
screen.flip()
end
Can someone help? And thanks in advance!Code:
