In the script posted "AS IS", how are you getting the char id?
In other words, how GGMax is going to know which character are you referring to at some point?
Usually, GGMax uses 2 ways to ask about it, (e) and name, assuming I have an item named "mytable" the id = 2, so:
id = 2
name = mytable
so, GetEntityName(e) throw as result "mytable" and something such as:

function hello_init(e)
id = e -- gives you the entity id, or
id = tonumber(e)
end

now you would can to work as for example:
character(id).name = GetEntityName(id)
or
PlayerDist = GetPlayerDistance(id)

Perhaps you already know that, but just in case.

use the code tags to post your code
and this isn't AI code - from what i can see it seems like mostly valid code but no, it won't really "do" anything in GG.

Out of topic, but good to know.

Hello smallg, in the previous version of this forum, using the 'code tags' was easy.
Please could you teach us how we can do it now with this new version of the forum ?

Here is a small video posted on my Vimeo gallery (sorry, it is also not possible to use the 'video tag' for that purpose) :

https://vimeo.com/803027696

yes none of the tags work by default for me either but you can still type them

(without the spaces in the square brackets)

@ smallg. it is supposed to train AI, it loops until desired result and saves the file. I thought this would be like an AI trainer for better bots.

we can't see the whole code so it's impossible to say if it works as intended or not
