Can you provide detailed reproduction steps? I cannot get the game to crash with a map with a terrain with more than 4 characters or when defining a terrain type with more than 4 characters. (Both of those cases show an error in the GUI for me.) Bit hazy here as it was ages ago but I had a similar ...

Correct. Note that putting Lua in an event doesn't fully isolate it from the rest of the scenario though. It will only be executed when that event fires, but that code can change global variables, move units around, and do many other things that affect code running elsewhere in the scenario. On the...

...If you put the Lua code inside a... And of course, if you put the Lua code in an event or menu item, it will be executed only when that event or menu item fires. Interesting, thanks. I hadn't realised you could "isolate" lua code from everywhere in a campaign except for one event... Bu...

Hi everyone, Thanks for all your help and patience, much appreciated. I now have a short lua snippet in my campaign that does what I want (it's not fully tested yet and I need to check it's replay safe but the actual logic works). I'm a long way from being familiar/confident with lua but at least I ...

So that's true everywhere?
Oops...
Ah well, I've learned something!

Cheers!

...I want to learn lua better... Heh, I am currently going through the exactly same process starting from a position of knowing zero lua. Note that the wiki isn't quite right so don't make my mistake of spending *hours* debugging something that will never work... :augh: Good luck. Cheers! -- Spanne...

I'm trying to remove unit with id=$unit.id from array of units "side_7_retreat_micro_ai"...

Just curious, but why lua?
A [for] loop would do that - and for me anyway, it's a lot easier to debug!

Cheers!

As you're dealing with one unit, I think you can maybe dispense with [modify_unit] and put the [filter] in [object] ? It would save a bit of space - but it's nothing like what you want to do so maybe something to consider if no-one else suggests anything better? [insert_tag] might be able to do what...

However, if you only store those units purely to associate them with the micro_ai I think you could replace all your code with: I think that's quite different. The first looks like "If you're not in the water/swamp or near some location RIGHT NOW you get assigned the mai". The second look...

Glad you got it sorted, and I learned that [music] works there.

Cheers!

I've not used that particular micro_ai but you don't need to use a loop. Instead, inside your [micro_ai][filter] you could just have find_in=units_to_micro_ai However, if you only store those units purely to associate them with the micro_ai I think you could replace all your code with: [micro_ai] si...

I want to play a short bugle call and show a picture on the scenario start screen. Picture works fine. (well, it won't scale; can the picture's size be changed? The text window covers the bottom, would like the pic not to overflow into the text window) Music won't play. It was placed in the "a...

@gnombat Are you sure that's not supposed to be wml.tag.variable ? Heh, I trusted the wiki and didn't know about wml.tag.variable... Thanks for pointing this out! @Ravana wiki is wrong, wml.variable does not exist. It was supposed to be wml.tag.have_unit and wml.tag.variable. Lua also knows some com...

A couple of quick things you might try: See if there's anything helpful in the logfile. Purge the cache (main menu->preferences->cache) and try again, the error might re-appear (and also be in the logfile which saves faffing around with screen grabs if you're lucky). Sorry if this is bit terse, was ...
