image limit in lua?

i have a game i have written in lua. i load images at the start of each script , i have one for the game, menu and scores screens. each one loads 7-8 images aprt from scores.

my question is is there a limit to images loaded ? and if so is there a way to clear the memory, as i keep getting errors and the only possible reason seems to be im loading to many images in each script or cumulativley over the 3 .

edit:it works fine on the pc lua player but returns errors on the psp

yes, that would be why.
i recommend learning C instead. It isn't very much harder, and it is easy to port lua to C.
if you want to learn, go to www.psp-programming.com

no real limit on no. of images in lua,but
sounds like RAM overflow. At the end of
each script, undefine any images no longer
needed (eg level1Background = nil) and the
garbage collector should free up memory for you
automatically

*EDIT* making images local to the script
would have the same effect

thankjs dangee that worked a treat

pleasure, btw theres loads of good lua stuff at evilmana

lol im actually using that site anyway. one more question. i have a lua game id like to release here how do i do that? its not a standalone, just a folder to go in apps and works with lua player 0.16 best, o.20 returns a lot of random errors for no reason.

Just release it in the develoment forum

You can post it in the Submit News forum.

If you're talking about how to boot it without having to play it from Lowser, here's how:
1- Open up the System\system.lua
2- Replace

Quote:

---

System.currentDirectory("Applications")
appsDir = System.currentDirectory()

System.currentDirectory("Lowser")
dofile("index.lua")

---

with

Quote:

---

dofile("script.lua") <---- Your index script file.

---

It should autoplay without having to play it from Lowser ;).

thanks -Xandu- will do that

When doing that you can get rid of the "Lowser" folder.

..& while your at it,
move script.lua to /PSP/GAME/LuaPlayer/
(where the eboot is), and remove all the other subfolders and their files..

(adding to this one i dont want to make a newe thread unecicarily) does anyone know how to deal with stack dumps? i have a script which on reading has no errors in the lua code but when i run it it produces luaplayer.exe.stackdump with some random numbers. can i fix this or do i need to re do the script somehow?

Usually it means you have blown the stack memory. E.g. Loading too many images, infinite loops loading resources etc.

tbh i dont think i have, at least i dont think so. any chance someone could look over my code for me? any takers tell me and ill upload it somewhere and put a link. it would help so much

edit: this is for a side scrolling shooter im trying to make, not my console grab game

edit: here is my script with lua player and materials, plz have a look and see what ive done wrong im completely stumped

stack overflow can be a pig&a1/2 to fix! Id like to try n help, but stuck at the moment
on a PiKey problem.
if NE1 can help out , itd free up some techtime for ur debug

The stack error is something with your images, I tried the images from your Console Grab game and it worked fine ;).

thanks xandu ill try swapping them out or re doing them.

you were right xandu thanks a lot ill just have to redo the gfx for it, i needed to anyway tbh lol

edit: working fine now got the ship (a psp atm) firing 4 bullets (ds's atm), next up coding in 4 enemies and collision tests for enemies vs bullets and player vs bullets......
