[Help] Making my character give sanity aura around other player with a maximum of 2 players near

[Alexander Lynx]

Hi! I'm making my first mod because i wanted to add a character i made in the game, i'm not really good at coding so i was wondering if someone could help me with a perk! 

Basically what i want my character to do is to give a sanity aura (Like a gloomer) to other players around, with a maximum of 2 players near my character (If there's 1 person near he will still give sanity aura)

But when there are 3 or more players near my character, he will give an insanity aura instead 

 

I know that is it possible to make a character give sanity aura, but i'm not so sure if something this specific can be made 

Many thanks for the help!

These should get you all the information you need to make that perk.

Before you start, though, you should familiarize yourself with Lua and DST modding. Start with the newcomer post, do the Lua Crash Course linked there, perhaps browse my tutorial collection for some information about different parts of a mod.

It tells you what's wrong right here:

[string "../mods/Alexander The Lynx/scripts/prefabs/alexander.lua"]:135: 'end' expected (to close 'if' at line 106) near '<eof>'

It expected an "end" to close your if-statement started at 106, but the if-statement is closed (going by your indentation) but the for-loop isn't closed. You need to close your for-loops with "end", just like the if-statements. Did you do the Lua Crash Course? It's very different compared to most other languages. You have to understand its object-model and weird syntax, in order to write anything good in it. For example, have fun coding without the "continue" keyword

I could finally get the code to not crash! XD 

But whenever i select my character this shows up in the log:

It seems your "names_gold_alexander.xml" isn't present or is named wrongly, or that the xml-file hasn't been edited to refer to the right texture.
