Getting somethingto follow you...

client
    Northwest()
        var/mob/monster/M = new (usr.loc,usr)
        M.dir = usr.dir
        step_towards(M,usr)

Anyways, whenever I create the mob, it doesn't follow. :9
Would I do this by using step_to, or a totally different thing?
What I mean is...

O = Player
M = Monster
X = Ground

XXXXXX
XXXPMX
XXXXXX

That's the player going left.

XXXXXX
XXXPXX
XXXMXX

And that's the player going up. ;o
How would you go about doing that?

What you're doing above there should be creating a NEW monster everytime you move Northwest...

1) Stop using usr in proc's.

2) Make the Monster(or what seems more like a pet) have it's own proc to follow a player.

To do so, you can set a variable to the monster indicating who it has to follow(in this case the Player). Then in the monster's new proc, spawn a proc which constantly follows(using step_towards) the variable(the player) and then loops itself(using while?), but make sure you put a sleep() in the loop, or it'll create major lag up to a point the game crashes.

3) You dont need M.dir = usr.dir.

"usr" has to be put in, as of it's the client.
I could've used "C", but I needed a fast example.
Well, thanks.

No instead of usr you can use mob. So...

mob.density = 1
mob << "Haha it sucks to be you"

...are the correct ways of doing the player, in client/procs, or atleast I think.

Ahhh, well... >_>... I was using Northwest just for a test, and now another question...

        create_monster()
            if(src.monsters.len >= 3)
                for(var/mob/monster/M in src.monsters)
                    src << "You have too many monsters!"
            else
                var/mob/monster/M = new(src.loc,src)
                M.owner = src
                M.name = "Drakee"
                src.monsters += src

;o
<font color = red>
runtime error: Cannot read null.len
proc name: create monster (/mob/verb/create_monster)
usr: Hell Ramen (/mob)
src: Hell Ramen (/mob)
call stack:
Hell Ramen (/mob): create monster()
</font>
It can't read the "len" part I suppose, but I can't think of any other way to do it. :(

I don't know about checking sizes of lists but an easier approach would be to make a new variable called something like monnum and check against that:

        create_monster()
            if(src.monnum >= 3)
                for(var/mob/monster/M in src.monsters)
                    src << "You have too many monsters!"
            else
                var/mob/monster/M = new(src.loc,src)
                M.owner = src
                M.name = "Drakee"
                src.monsters += src 
                src.monnum ++

Now it has a type mismatch. :(
<font color = red>runtime error: type mismatch
proc name: create monster (/mob/verb/create_monster)
usr: Hell Ramen (/mob)
src: Hell Ramen (/mob)
call stack:
Hell Ramen (/mob): create monster()</FONT>
Should I use...
if(src.monsters.Find(M,Start = 1,End = 0)
M.name = "Drakee [pick("A","B",C"]
?

Well, thanks for the help so far. :D

[Edit]: Note, this is only if I create more then one... later I'm going to make it so if(tmon = 2),M.follow2(),etc.

What line is this on and show me how you've defined the monsters variable.

mob
    var
        list
            monsters
        monttl
            
    verb
        delete_monsters()
            del(src.monsters)
        create_monster()
            if(src.monttl >= 3)
                for(var/mob/monster/M in src.monsters)
                    src << "You have too many monsters!"
            else
                src.monttl ++
                
                
                var/mob/monster/M = new(src.loc,src)
                M.monsternum = src.monttl
                M.owner = src
                M.name = "Drakee"
                src.monsters += M //Right here


:o
That's how I'm doing it, I don't get what you mean... so, yeah. =/
[Edit] It's the "src.monsters += M" part. :o
Line 158, I figured out Debug Mode. :D

Both of those errors are because you didn't actually create the monsters list; you declared it, but you didn't actually give it a value. Set it to list(), like so:

mob
    var
        list
            monsters = list()


Now you can also get rid of that dodgy monttl variable and use monsters.len, which is a whole lot more reliable because you don't have to remember to increment/decrement it all the time.

Also, don't delete src.monsters; that will delete the list, not the monsters. To delete the contents of this list, you have to do this:

for (var/mob/monster/M in src.monsters)
   del M


And finally, why are you looping through src.monsters to say "You have too many monsters"? You'll just end up with the message getting displayed three times for no reason.
