LuaRules in Map files (revisited) and 77b4

[tinnut]

Hi Guys,

I've written a couple of LuaRules gadgets that I had intended to put into some maps I was working on - a teleporter, unit duplicator, and an "end game" scenario for a map where you have to hold 5 points to win. I'd just gotten them working under 76b1, with some graphical effects, only for them to stop working under 77b4.

Does anyone know of anything that changed that would have likely caused this and/or how I could work around it?

Under the svn build of Spring that came with the first release of PURE they still work (conversely the "WorldBuilder_GPL" map seemed to loose it's rain when I tried to run in under 77b4).

For now I guess I'll go back to looking through the Spring source code to see if I can find it myself.

Cheers.

You don't get an error in Infolog, just a crash or non-functional Gadget?

[tinnut]

No errors in Infolog and Spring just runs fine without crashing.

My Initialize() call-in's both run for synced and unsynced, but my gadget:DrawWorld() call-in from my unsynced code isn't, and neither is my gadget:GameFrame(framenumber) from my synced code.

Even when I trim the code down to just the above call-ins and have them both do nothing other than a Spring.Echo so that I know that they've run, they still don't work.

I might try a clean install of Spring tonight and maybe look closer through the gadgets.lua code as well as the related c++.

[Argh]

Hmm. Strange. gadget:DrawWorld() and gadget:GameFrame work just fine over here, although I should note that GameFrame is a sync operation, IIRC. If you'd care to post some code, I'll give it a whirl, see if I can pin it down.

Thanks for your assistance Argh.

I did a clean install of 77b4 and found that the LuaRules in my map didn't work for the latest versions of BA or CA, but did work for an older mod that didn't have any LuaRules scripts in it, so it must be some conflict happening.

This gives me somewhere to start at least :)

I noticed from the log file that when I launch BA (or CA) with my map that one of the LUPS lua scripts fail, but when I use my map with its lua removed, there are no errors. I'll work back through the source and see what's run and when.

You're supposed to use LuaGaia in a map, LuaRules is only for mods.

[Forboding Angel]

That's not entirely accurate KDR, but unfortunately I dunno how to explain why I would say that. Argh could prolly explain what I mean.

[jK]

KDR is right.

The only reason why LuaRules gadgets in maps get loaded is because the current VFS can't differ between mod and map files (they are just handled as zip/base files).

PS: also this example shows why -> the map LuaRules gadgets could crash the whole LuaRules enviroment or interact with the mod gadgets in way the modder didn't predict/want.

[Argh]

All right... so we move them to the LuaGaia folder... is that all, or this there something else that needs to be done?

[jK]

you have to setup the gadgetHandler enviroment:
* copy main.lua,draw.lua,gadgets.lua etc. (or link the basecontent ones)

[Argh]

Cool, that basically means I'll just have to move the files, np.

BTW, kudos:

* fixed a bug in lua's fontHandler (it was the bug, which decreased the fps by >50% and was fixable by reloading luaui)

That was obnoxious

[tinnut]

Thanks for all the info guys.

I'll convert my stuff over to LuaGaia although this will mean loosing some functionality due to the restrictions that LuaGaia has to work under compared to LuaRules. I had suspected that using LuaRules in a map was a bit of a hack, but it was worth trying at least.

Some of the stuff I was trying to do would have been quite unbalancing for some mods, but the worst offenders were mostly meant as a laugh.

Cheers.

Would you please post said widgets? I have a map concept im working on, and I would like to build on your work
