NPC functions - Egate2

[ZeikJT]

I don't know what works on an NPC and what doesn't so I'll list some commands that can be used on entities:
entity:EyeAngles( )
player:SetEyeAngles( Angle )
entity:SetAngles( Angle angles )

For the weapon, do the regular routines not work?
player:HasWeapon( string WeaponClass )
player:GetWeapons( )
player:GetWeapon(String Weaponclassname)( )

Thanks a bunch! These will be useful whether I use them for these NPC functions or not. I was using SetAngles() though.

I can't say if regular routines work, since I didn't know what regular routines were. I'll try them.

You can always look here for entities:
Entity - GMod Wiki

Here for players:
Player - GMod Wiki

Here for npcs... very disappointing though:
NPC - GMod Wiki

Oh and this function is also important and not directly linked to on npc page:
NPC.StartSchedule - GMod Wiki

EDIT: On testing I found that GetActiveWeapon returns the weapon entity the npc is using. So that should work fine for detection.

Yeah I know about those first links, but the last one solves a fair few problems for me, thanks!

No problem. Since there are so many functions in red it could be helpful for you to test these things via console.
Some noteworthy commands to use for debug in console:
lua_run
lua_run_cl
You put that in the console followed by lua code and it will run, example:
lua_run print(ents.GetByIndex(1):GetName())
lua_run PrintTable(debug.getinfo(_R[4].GetNPCState))

You can test out the NPC functions from there without having to code, restart, code, restart...
If you want you could even dump the _R table, specifically subtable 4. It has a lot of the NPC available functions:

lua_run file.Write("global/_R4.txt",table.ToString(_R[4],"_R[4]",true))

or for the entire _R table:

lua_run file.Write("global/_R.txt",table.ToString(_R,"_R",true))

or for the WHOLE _G table, it includes _R:

lua_run file.Write("global/_G.txt",table.ToString(_G,"_G",true))

It will dump to a garrysmod/garrysmod/data/global/ folder, you can change that if you want to.

Updated with relationship functions and E:npcGiveWeapon(S)

Any chance of checking to see if an NPC has a certain type of relationship towards an entity?

if(A:Likes(B)) ...

EDIT: Got bored, and decided to make a patch implementing this functionality.

   local entity = checkEntity(rv1)
   local target = rv2
   local disp = 3

Gonna try and test this since I'm pretty sure I screwed up the arguments somehow.

EDIT[2]: Forgot the return type, lol
EDIT[3]: E:npcHate(E) works now, the others should, as well.

Okay I didn't add all those because there are a lot, but I did rewrite them into one function:

function DispToString(number)
   if(number == 1) then return "hate" end
   if(number == 2) then return "fear" end
   if(number == 3) then return "like" end
   if(number == 4) then return "neutral" end
   return 0
end

registerFunction("npcDisp", "e:e", "s", function(self,args)
   local op1, op2 = args[2], args[3]
   local rv1, rv2 = op1[1](self,op1), op2[1](self,op2)
   local entity = checkEntity(rv1)
   local target = checkEntity(rv2)
   local disp = entity:Disposition( target )
   if( !entity:IsNPC() || disp == 0 ) then return "" end
   return DispToString(disp)

end)

This should return a string of the NPC's disposition. "hate", "fear", etc. I'll test it later, and for now it's added to the files on the first post.

Okay. I've fixed the functions in my post so they actually work if added as-is. I've tested E:npcHate(E) and E:npcLikes(E) so far, the others are pretty much just copypastes with changed disp values.

This seems pretty cool! Its justa a shame that most servers don't allow npc's...
This would be cool to turn Npsc's into guards to protect a base...
