How to display image via Lua?

Hi,

if there is a list set up like that:

Code: Select all

listname = {
  {variable = "what ever", anOtherVar = 5, andAnBool = true, },
  {variable = "what ever2", anOtherVar = 3, andAnBool = true, },
  {variable = "what ever3", anOtherVar = 3, andAnBool = false, },
}
how would i insert my own entry without replacing the old list??

Code: Select all

{variable = "custom1", anOtherVar = 3, andAnBool = true, },

Code: Select all

listname[table.getn(listname)] = {variable = "custom1", anOtherVar = 3, andAnBool = true, }
This will append your custom line at the end of the table. If you need to put the new entry in the middle of the list somewhere then you might want to use:

Code: Select all

table.insert(listname, <key #>, value)
You can actually use table.insert() with only two arguments and achieve the same result as my first example, if you prefer. I'm pretty sure both operations take roughly the same amount of system resources to complete. For example:

Code: Select all

table.insert(listname, value)
This will do exactly the same thing as my first code example.

Alright i'll test it. Thank you.

==Edit==
got this message: (none):0: attempt to call field `getn' (a nil value)

==EDIT2==

tried the other method from you and got that:
(none):0: attempt to call field `insert' (a nil value)

Hm, can you try the other method I suggested? (The third code example). I remember now that table.getn() is not really good practice for tables and is actually meant for arrays. Try using table.insert() instead. I've never had trouble with that one.

have you seen my edit 2?? same problem.

(none):0: attempt to call field `insert' (a nil value)

Here the the whole code:

Code: Select all

You never defined gLegalScreenList before you tried to insert MyCoolValue into it. You at least need to define it beforehand. Right at the beginning of the script you can put gLegalScreenList = {} and then fill it in later.

Re: lua list how to insert entry

Posted: Thu Mar 31, 2016 10:54 am

gLegalScreenList is defined in the ifs_legal file.

Oh yeah, right. It's a global variable so I'm not sure why your script won't read it. Are you munging ifs_legal in your custom shell at the same time? If not, try adding that into your req.

Re: lua list how to insert entry

Posted: Thu Mar 31, 2016 11:16 am
by Anakin
no i didn't munge the custom shell, but i don't have a custom shell. It's a custom_gc script.

==EDIT==
i added the ifs_legal script to the custom_gc lvl but still the same problem.

I don't have any experience with custom GC. I do know that when it comes to anything shell related, it needs to be munged together. Try loading ifs_legal with your custom script (same req). Or use ScriptCB_DoFile at the top of your script.

Edit: Saw your edit. Try the DoFile suggestion.

Re: lua list how to insert entry

Posted: Thu Mar 31, 2016 11:24 am

jep did that. i munged ifs_legal in my cusomt gc script, but same problem. next i added ScriptCD_DoFile at the top, but then the AddIfScreen wrapper never come to ifs_legal

Re: lua list how to insert entry

Posted: Thu Mar 31, 2016 11:25 am

What if you try doing all of this as a custom ifs file instead of a custom GC? Then you can munge it all together with no broken dependencies.

Re: lua list how to insert entry

Posted: Thu Mar 31, 2016 2:10 pm

but that way I replace the stock ifs_legal and won't be able to make it compatible with others.

Re: lua list how to insert entry

Posted: Thu Mar 31, 2016 2:24 pm

You don't have to replace it, just make a brand new one for your GC. Edit: again, I'm not a GC expert, but I do have experience modding the interface. The bottom line here though, is that you need that table, otherwise table.insert() is always going to fail. Make your own table if you want to.

Re: lua list how to insert entry

Posted: Thu Mar 31, 2016 5:29 pm

I understand. The GC is not a big thing. It's just a way to insert custom code and to change some functions with a wrapper.

About the custom ifs_legal. I just want to display one picture with the possibility to skip it. You say you know about interface programming. Is there a way to shorten the ifs screen code??

EDIT: Sorry, I misread your question. Typing the correct response right now.... (/edit)
EDIT 2: I just realized how late it is here... I will finish my response in the morning. :P (/edit 2)

Do you mean shorten it as in make it take less time to go through the images? That's fairly simple.

Code: Select all

gLegalScreenList = {
-- 	{ texture = "bootESRB", time = 4, bNoPAL = 1, },
	{ texture = "bootlegal", time = 5, },
	{ texture = "lucasarts_logo", time = 3, bSkippable = 1, },
	{ texture = "pandemic_logo", time = 3, bSkippable = 1, },
--	{ texture = "nvidia_logo", time = 3, bSkippable = 1, bNoPS2 = 1, bNoXBox = 1, },

	-- play the movie unless you hit x to skip, the show the texture.  else skip the texture.
--	{ movie = "pandemic_logo", texture = "pandemic_logo", time = 3, bSkippable = 1, },

--	{ texture = "logodolby", time = 3, bSkippable = 1, },
	{ texture = "dolby_logo", time = 3, bSkippable = 1, },
}
Change all the time values to something lower like 0.6 (which happens to be the length of each screen if you "skip" by clicking through the logos).

I want to add my own ifs screen after ifs_legal. But my custom ifs won't display a list of textures, i want only one image be displayed. That way i think i don't need to copy the whole ifs_legal script since i don't need a function ifs_legal_GotoNext(this,bWasSkip) since there is no next image.

I don't understand much of that, so what are the important parts that display the image, start the countdown, can be aboard by klick and go ahead with the next ifs screen??

My interface tutorial is up, though I admit that it feels kind of jumbled together. I'll add a few things to make it clearer later. Check it out here.

I don't talk specifically about this topic (legal screens) but I cover some similar topics so you might still find it helpful. I'll try and have a look at your example and see what I can do.

OK i made it to hack myself into the legal screen and to display my own ifscreen right after ifs_legal. Now you need to tell me why nothing is shown:


For me it looks identical to the ifs legal screen, with just renamed functions. But for some reason it does not work

This looks nice and everything, but the stock ifs_legal file is really way too cluttered for what you need. I would recommend building a new screen from scratch, because currently you've got all this leftover controller initialization stuff, and a bunch of garbage related to the XBox DVD demo version, etc which is all unnecessary and could actually be causing problems since it's already run once before in the ifs_legal screen. I'll try and write a shorter version this morning and you can tweak that to your liking.
