Conno1234	I made a game where I could attack, kill, and earn money but the mob being attacked couldn't fight back. I'm not sure how to make it so that when I attack them, they attack me. Please help! (P.S. The mob isn't another player online, it is just a figure sitting there.) I will take any answers because I have tried and failed many times. Thank you. :)

Conno1234	"Bump()" ??? What will this do? Is it a procedure?

Jun 8 2008, 1:20 pm
Darkmag1c1an11	Don't try Bump(), it will do nothing for you in this case. I have a couple of methods in my head to help with this, but I'll let Garthor or someone experienced come in, since I think my methods are inefficient.

Conno1234	Ok, but who is Garthor?

Jun 8 2008, 1:25 pm In response to Conno1234
Darkmag1c1an11	Garthor is a robot that's awesome at DM programming.

Jun 8 2008, 1:28 pm In response to Darkmag1c1an11
Conno1234	oh ok but does he talk to people and answer their Q's?

Jun 8 2008, 1:35 pm In response to Conno1234
Conno1234	Besides Garthor, you said that you had a couple of methods. Would you mind sharing them with me?

Giantpanda	It wouldn't be surprising.

Popisfizzy	Look it up in the ref (F1 in Dream Maker).

Garthor

Basically, you'll need to write an AI routine for the enemies. This is a very, very broad topic, and can cover a wide range of things. The simplest AI goes something like this:

1) Pick an enemy that we can see
2) While that enemy is still in range:
a) If we're close enough to attack, attack
b) Otherwise, step closer
c) Repeat
3) Repeat

So, we'll do something like this:

mob
  var/tmp/mob/target = null
  proc
    AI()
      while(src)
        //Find an enemy of type /mob/player
        target = locate(/mob/player) in oview(src)
        //while they're still in range
        while(target && (target in oview(src)))
          //attack if we can
          if(get_dist(src,target) <= 1)
            src.attack(target)
          
          //otherwise, get closer
          else
            step_to(src, target)
          
          //wait a little while before moving again
          sleep(10)
        
        //wait a little while before looking for a new target
        sleep(10)

There are about a million ways to improve on that, but that's a start.

Really?

mob/monsters/Bump(mob/player/MM)
    if(istype(MM))    // This is shorthand for istype(MM,/mob/player)
        src.Attack(MM) //attacks the player
        src.death_check(MM) //checks if it's dead

I've TESTED that - it works.

Onto moving monsters...

mob/var/mob/player/Target

mob
    monsters
        icon='monsters.dmi'
        New() //when any monsters are created
            ..() //make sure it happens
            spawn(5) 
                src.Wander() //starts Wander()

mob
    proc
        Wander()
            while(src) //a loop.
                sleep(5) //sleeps 5 ticks
                for(var/mob/player/MMMM in oview(1)) // how far you want the enemy to target a player
                    Target = MMMM //MMMM is the player in oview
                    break 
                if(Target) //if it has a target
                    walk_towards(src,Target,5) //walk towards them
                else //if not
                    walk_rand(src,5) //walk randomly

Garthor	That's bad code. Don't post bad code.

Garthor	It works in the limited case you've provided. It is, however, screwing up a number of things, like using usr in procs (AGAIN, I MIGHT ADD) and using walk_towards() like step_towards(). Bad code is bad code. Don't post it.

There isnt any 'usr' there. And I lulz'd at the bolded. fail 4chan meme is fail?????

Garthor	That wasn't a 4chan meme, it was simply a statement of identity. As for there not being any usr in it, that just shows your own ignorance. See: http://www.byond.com/docs/ref/info.html#/proc/oview Another reason you should refrain from attempting to help people.

Garthor	I linked you to the reference. The default center argument for oview() is usr. You did not provide a center argument for oview(). Therefore, it defaulted to usr, and you used usr in your proc.
