Text file limit on iOS

Solar2D General Questions/Discussion

Hello all, is there a text file limit for an iOS game? For example if i am going to create random generated levels while running the game where each level is saved in a different text file, is there a limit for the number of text files or size?

Another question is about storyboard, is this a scene manager like director class or i am wrong?

I can’t say for certain, but I doubt there’s a “limit” on text files, especially Plain Text files. Even a text file with thousands of lines is probably smaller than a typical JPEG or PNG image in your app.

The “limit” you should concern yourself with is how you process and read these files. In one of my apps, I read several chunks of information (100-200 lines) from an external file and load this into Lua tables so I can deal with it. Using proper string patterns, Corona is really fast in reading this information… but if you place 1000 entries from a text file into one Lua table, you might not approve of the performance. Breaking them up into proper sub-tables is recommended, and be sure to keep them clean, delete them upon exit, etc.

Thanks for the reply. I’ve been testing around and it is working good so far. And thanks for the tips on how to read files.

The only thing i need to figure out now is a way to check the memory of a phone. So i can stop creating/generating maps when it reaches a certain limit.

Once again, thanks! [import]uid: 74723 topic_id: 25897 reply_id: 104864[/import]

I personally like this memory-checking code, courtesy of Jonathan Beebe (Ansca). I might have modified it slightly (printing the value to the Terminal, not the screen), but credit Jonathan for writing the original code. :slight_smile:

local function garbagePrinting()  
 collectgarbage("collect")  
 local memUsage\_str = string.format( "MEMORY = %.3f KB", collectgarbage( "count" ) )  
 print( memUsage\_str, "TEXTURE = "..(system.getInfo("textureMemoryUsed")/1000000) )  
 --mem.text = memUsage\_str  
 --texmem.text = "TEXMEM: "..(system.getInfo("textureMemoryUsed")/1000000)  
end  
local t = timer.performWithDelay( 1000, garbagePrinting, 0 )

iOS is built on top of a Unix based system and pretty much has an insanely large max file size. So I wouldn’t worry about large text files. I have several 100Kbyte and one 2MByte text file for an app and I don’t notice any delays in reading it.
