if it opens, it works,,
the error your geting now has to do with an image, make sure it has the correct path so lua can find it,, just put it in the same folder as you script file, then in your scrip put the image name (and extension),
its on line 4 of your code
Done that and it still doesnt work. Ive tried it with any lua app using an image and I get the same error.
make sure the image is a png or jpeg,, lua cant load gifs or bmps
They are PNG's
Check that your images folder isnt really Images or grass.png isnt Grass.png.
Check for capital letters basically.
Ok checked. They are all correct. Oh well, Ill guess ill leave it. Im starting my first game right now. Its called Lua Zelda and I know its quite ambitious to dive into something deep but at least I will learn :D Expect to see alot of me!
Ok. I dont think my Lua on my PC is installed right as nothing works on it all. So, please can some give me the direct download link to the correct one and a step by step installation guide. Cheers!
you don't need an installation. the download is on www.luaplayer.org
double check the folder names also.
Yea nvm. Thx anyway!
ok, i keep getting this error,, its not a regular lua error, its bigger(huge letters) and freezes the psp,, but sometime it wont show it and freezes the psp.
i know there is nothing with the script files, cause the were working before(didnt edit them) its when i try to open certain files(even when i rename them it does this)
ok heres the error:
LuaPlayer's MikMod has a critical
_mm_critical 0
_mm_errno 1
Cannot open requested file
well i dont know. I have does too sometimes. Usually its something with the memory if im not mistaken. If i restart the PSP its gone.
But since it says cannot open requested file, maybe you're trying to open files that LUA cannot open?
ok, ive fixed the problem now,,
i moved some files in a folder and forgot to change the path in lua,,
its seems that if its multiple files missing it goes to that, instead of the cannot find file error it usually shows,,
Ok, my question is:
Is there a way to fade a image into another image?? If so please can I have a code example. Cheers!
Can't you use the alpha channel for that? I believe you said in another thread only 255 and 0 worked on an image. But on screen all the values work. So just blit them on the screen.
Is there another way to do the "canvas:clear(BGcolor )", i would like to not clear the image, is that possible?
Code:canvas = Image.createEmpty(480, 272)
BGcolor = Color.new(255, 255, 255)
canvas:clear(BGcolor)
while true do
screen:blit(0, 0, canvas, false)
How do you mean? If you dont want to, than you dont, right?
The problem is that i would like to change the background in my paint application, which is fine exept that the drawing image covers it and reverse if it's a clear() object.
Sorry if this is the second time for me posting this problem (I did two days ago, but with no responses), but here is my problem:
Okay, I want to changetoCode:if pad:up() and jpos == 0 then
jpos = jpos + 1
end
so after three seconds, the variable can reset back to normal. However, this isn't happening, but instead it's like the timer isn't even there and it dosen't even let jpos = 1, it goes immediately back down one, so there is no change. My question is, how do I get a working timer?Code:if pad:up() and jpos == 0 then
jpos = jpos + 1
screen.waitVblankStart(180)
jpos = jpos - 1
end
And heres the full code so far if anyone wants more of a look: here (oh, and ignore the Timer.new.. I forgot to delete it.
Thanks for any help.
well I'm not sure exactly what you're trying to do with it all without seeing the images.. the way you dimmed your variables as "jpos" and "epos" made me think they were positions that the images should appear rather than boolean values whether TRUE or FALSE they SHOULD appear or NOT.. Anyways I re-wrote the script hopefully it will work for you. When turning things on and off, I prefer to use "true" and "false" rather than "0" and "1". Try this out and let me know if it works for you:Zitat:

Code:black = Color.new(0, 0, 0)

screen:blit(0, 0, vs)

@ HaxxBlaster:
Draw the image on a separate image as the background, i.e.:
Code:background=Image.createEmpty(480, 272)
canvas=Image.createEmpty(480, 272)
BGcolor = Color.new(255, 255, 255)
background:clear(BGcolor)
while true do
screen:blit(0, 0, background, false)
screen:blit(0, 0, canvas, false)
Question: does it make your app faster if you make a var a boolean instead of a var with 0 and 1?
Do is this faster:
if whatever then
...
end
Or is this:
If whatever==1 then
...
end
Or is it the same? Im asking because my game has some serious framedrop problems.
Also does anyone know how the os.date/os.time command works? Im trying, but it just isn't working. If so can you put an example?
os.date("*t") time values
os.date("%c") full date
usage:
timeNow = os.date("*t")
hh = timeNow.hour
mm = timeNow.min
ss = timeNow.sec
there are all sorts of operators you can put in there
%a abbreviated weekday name (e.g., Wed)
%A full weekday name (e.g., Wednesday)
%b abbreviated month name (e.g., Sep)
%B full month name (e.g., September)
%c date and time (e.g., 09/16/98 23:48:10)
%d day of the month (16) [01-31]
%H hour, using a 24-hour clock (23) [00-23]
%I hour, using a 12-hour clock (11) [01-12]
%M minute (48) [00-59]
%m month (09) [01-12]
%p either "am" or "pm" (pm)
%S second (10) [00-61]
%w weekday (3) [0-6 = Sunday-Saturday]
%x date (e.g., 09/16/98)
%X time (e.g., 23:48:10)
%Y full year (1998)
%y two-digit year (98) [00-99]
%% the character `%´
see: http://www.lua.org/pil/22.1.html
http://www.lua.org/pil/
for example I'm using os.date("%A, %B %d, %Y) to return "Monday, March 27, 2006"
Don't bother, i fixed it.
But i have trouble with a load/save functions, i got the code but i really don't understand how it works, and where it will get the other info from.
But i would like to load a lua string, but i guess that numbers only are avaliable?
I would love this command, which would save the luafile as it currently are in game.
If that would work you could create image after image in a ect. paint app without overwrite.Code:file:save("screenshot.lua")
I Would also like to look intoZitat:
Zitat von HaxxBlaster
the save and load functions :icon_cool .
But i need it to save stuff as "Chao Name" And stuff...
Or probally load Mood=100 or just 100?
Maybe like this?
I really would love lit like this!
Code:Screenshot = 0
if pad:select() then
dofile "screenshot.lua"
Screenshot = Screenshot + 1
screen:save(Screenshot..".png")
file:save(Screenshot.."screenshot.lua") --- Outputs "Screenshot = 1" inside the screenshot.lua
end
Thx a lot califrag! Do you by any chance also know how to overclock the PSP using LUA?
I tried something like this (i read it somewhere):
system.setSystemHigh()
Its not the right command i know, but when i tried the one it didn't work. Does it depend on the version of LUA?
Some stupid help lol...
I need to know how to write to a file,
say like load and save?
And is there anyway i can
use a funstion like
if pad:cross()==fasle then
cusror=cursor[1]
end
?
PSPMillionaire recently added a tutorial on his site, www.evilmana.com that involves writing to files abd reading them. I think it's exactly what you're looking for. And I'm not sure exactly what you're trying to do in the second part, if you are using cursor as a variable and an array I don't think that will work.Zitat:
Zitat von c5cha7
you can use the dofile("your.script") to open up another file.
so
if pad:cross()==fasle then
dofile("script2.lua")
that would open up script 2 in the same directory.
I think he's talking about actually writing data to a file, like a highscore function.Zitat:

Nice :icon_cool .Zitat:
Zitat von pauldude550
Thanks for your help guys!
And sorry for the bother but i have never actually
made a game that needed to save/load...
looks like he was/is talking about both of the functions.
Wow you guys really did save me alot of time :icon_cool .
Thanks again! Now i can save/load game! Read files, and
hopefully sooner Write to files! :)

You have to have the latest unofficial version of lua v0.17dk (by Dark Killer)
http://psplua.com/modules/news/article.php?storyid=151
nil System.setCpuSpeedHigh()--sets CPU clock to 333mhz
nil System.setCpuSpeedMed()--sets CPU clock to 266mhz
nil System.setCpuSpeedReg()--sets CPU clock to 222mhz
Thx again califrag!
@c5cha7:
wont work. You have to use:Code:If pad:cross()==false then
Code:if not pad:cross() then
???Zitat:
Zitat von Altair
Heh? It works?
If pad:cross()==false then
something=cool+1 or whatever
end
Can someone help me out with this. Took a break from coding but im getting this error. (Its referring to the very last line which is an end statement)
http://i49.photobucket.com/albums/f2..._Shak3/lua.png
You have an extra "end" somewhere.
Well I took out the only one that makes sense to take out and now the loading screen keeps looping...
