(See the best response by A.T.H.K.)
Code:
mob/Creature/Enemies/Elf/DeathCheck()
    if(prob(20)) 
        new/obj/WoodSword(src.loc)
        ..()
    if(prob(20))
        new/obj/WoodShield(src.loc)
        ..()


How would i go about making monsters randomly drop things? The code I use above doesnt seem to be doing anything, and i'm new to coding so I have no clue what i'm doing wrong. Would somebody help point out my derp?

I think this is one of the best examples as it allows for a list of items with easy programming.

I am getting errors with that code, and i don't know how to fix them, sorry I just started coding.

Drops.dm:1:error: list: undefined var
Drops.dm:1:error: =: expected a constant expression
Drops.dm:9:warning: O: variable defined but not used

Yes well I said it was a good example :)

Copy and pasting things never work..

var/list/loot = list(
  /obj/Weapon/Sword = 65, // 65% chance
  /obj/Weapon/BiggerSword = 30, // 30% chance
  )

mob/proc/Die()
  for(var/a in loot)  // For each loot item...
    if(prob(loot[a]))  // If the player gets lucky...
      var/obj/O = new a  // Make the item and drop it at the mob's location
      O.loc = src.loc
  del(src)  // Kill the mob, or whatever custom procedure you have

I'm still having problems with them not dropping anything, it says no errors though. Am i supposed to add something else to make it work?

Sorry I made a mistake I missed the a after new, I have fixed the original code.

Still not dropping anything, My code looks exactly like that.

You do realise it won't drop an item all the time right?

Have you set up the objects in the list correctly? have you set icons for the objects?

How are you calling Die()

I'm calling Die() in my DeathCheck
    DeathCheck(var/mob/Killer)
        if(src.HP<=0)
            if(src.client)
                world<<"[Killer] Killed [src]!"
                src.HP=src.MaxHP
                src.loc=locate(23,86,1)
            else
                Killer<<"<b>You Killed [src] for [src.Exp] Exp!"
                Killer.Exp+=src.Exp
                Killer.LevelCheck()
                del src
                Die()
                RepopWorld()

I've set up icons and everything for the items i can use them, just not get them to drop.
this is my drop code
var/list/loot = list(
    /obj/WoodSword = 50,
    /obj/WoodShield = 50,
    )
    
mob/proc/Die()
    for(var/a in loot)
        if(prob(loot[a]))
            var/obj/O = new a
            O.loc = src.loc
    del(src)

I just looked at my code and realised i put Die() in after deleting the mob.... it drops now, thanks for the help :) How would i go about making each mob drop different things though?

mob/var/list/loot = list()

mob/Monster
    loot = list(  
    /obj/Weapon/Sword = 65, // 65% chance
    /obj/Weapon/BiggerSword = 30, // 30% chance
    )
    
mob/proc/Die()
  for(var/a in src.loot)  // For each loot item...
    if(prob(loot[a]))  // If the player gets lucky...
      var/obj/O = new a  // Make the item and drop it at the mob's location
      O.loc = src.loc
  del(src)  // Kill the mob, or whatever custom procedure you have
