Having a pet monster follow you

ID:166198

I've tryed at least 4 diffrent libraries to learn off of and nothing has worked. The first time the monster spawned but did not follow the player, the second time the monster didnt spawn at all. I've tryed for awhile now. Could someone please show me how to make a system where you choose a verb, which then you choose a monster in you contents, then the monster follows you. Puting this in code rather than explaining in words helps me more.

Well... look up walk_to() ... call it upon the pet being created and the owner is known.... or something similar to that effect 
mob/pet
  var/mob/owner
  New()
    ..()
    if(owner) walk_to(src,owner,1)

well a few things.
1.wouldnt it be var/mob/monster due to the fact your making the monster spawn from your invintory and follow the player?
2.I've tryed it with New() and then the commands but it didnt work.(can't show you my code of it, because i deleted it)
3.Wouldn't the "if(owner) walk_to(src,owner,1) be under the verb that is releasing the monster to follow you?

It was just an example, trying to show you how to use it (walk_to) <.<

New() is called when the object is made, hence why it isn't working right now... which is why, as I said before, this is called an example.

Here's another example (Meaning learn from it, not to directly use it):
pet
  Click()
    if(src in usr.contents)
       src.Move(get_step(usr,usr.dir))//Relocates pet to 1 step ahead of usr
       walk_to(src,usr,1)
    else if(src in oview(1))
       walk_to(src,0)//to stop the walk_to proc... otherwise the pet would jump out of the inv
       src.Move(usr)//moves it back to the inv

Geesh... bite my head off, all I did was look at the example you gave and asked those questions, I didnt use it at all.
But now how do i turn it into a proc so i dont have to keep putting it into every monster? below is what I have so far
        verb/havemonsterfollow(mob/monster/Dragon/M)
            M.Follow()

mob/proc
    Follow(mob/monster/M)
        if(M in usr.contents)
            src.Move(get_step(usr,usr.dir))
            walk_to(src,usr,1)
        else if(src in oview(1))
            walk_to(src,0)
            src.Move(usr)

I couldnt get the above to even show up in the usr's tab. I know, I know "no usr in proc ahhhh" but I couldnt think of how to arrange it. I cant figure out what I did wrong, but I probely hurt it with usr, but I can't figure out how to make it come from the usr. Oh.....Im so confused :(::::

Sorry for snapping but I am a near-sleep state...

The problem is, you did not looked/understood walk_to() in DM Reference...


it is as follows:

walk_to(Object, Target, Minimum steps away (0 is default...), Lag time (0 is default))


So what you did in the proc was made you walk to yourself...


also, I noticed you called the Follow proc as "M.Follow()" but the proc is defined as "Follow(mob/monster/M)" ... meaning that the proc will not work because you never defined what the pokemon was (M.Follow)

Revise the way you made your proc, because you kinda messed it up... as "X.Follow(A)" looks like you want the X (pokemon.. M in your example) following the A but "mob/proc/Follow(../M)" makes M (A) follow src (X)

One cool thing about BYOND is being able to store an entire datum inside of a variable of another datum. This can be used in many very useful ways, pets and whatnot are one of those ways. I'll give you a nice commented example since I'm in a pretty good mood ;). Just remember, it's only an example, you need to learn from it and adapt it to your needs.
mob
    pets
        dog
    var
        mob/pets
            pet // Notice how I typecasted it as a mob above
    verb
        MakePet()
            if(usr.pet) 
                usr << "You already have a pet."
                return // Already have a pet, don't need another
            usr.pet = new/mob/pets/dog(locate(usr.x,usr.y-1,usr.z)) //Makes a dog!
            

client  // Best to do this in client so you don't have overhead from NPC's.
    Move()
        ..()
        if(mob.pet)
            if(get_dist(mob,mob.pet) > 1) walk_to(mob.pet,mob,1,3) // Move the pet towards the player.


Nice and simple.

ok i fixed it finally :D
<font color=green>*edit* except now I cant recall them :(*</font>
Thank you for your help. Below is what i did to fix it, is there anything I should change to avoid problems?
        verb/Have_A_Monster_Follow()
            set src in usr.contents
            if(src in usr.contents)
                src.Follow()
            

mob/proc
    Follow()
        if(src in usr.contents)
            src.Move(get_step(usr,usr.dir))
            walk_to(src,usr,1)
        else if(src in oview(1))
            walk_to(src,0)
            src.Move(usr)

You seem to have misread me... your verb was okay, it's just that your Follow proc (mob/proc/Follow) that needs changing... I would show you what to do but I need to go to sleep now

I made it quite awhile ago but it's pretty much solid. If you need any explaining just ask, although there are comments on almost every line. =p

It's a pretty straight-forward and simple demo on having one thing follow another. Excuse my nasty comments of old. :P

Geesh... bite my head off, all I did was look at the example you gave and asked those questions, I didnt use it at all.

You're making it seem like he is flaming you, which is wrong.

I'd suggsest being nicer to people who are trying to help you.

Nadrew, client.Move() needs to return ..(). By default, it returns 1 or 0 depending on whether it was successful, and the way you're doing it right now, you're overriding that behavior. So Fries, where Nadrew wrote ..(), you're going to want to write . = ..() instead.

In extension to this, the if() check would probably also want to check the . variable, to avoid the function call if movement failed. Granted, the proc will merely return if within the minimum distance, but it would be more robust to assure that movement actually occurred before forcing the pet to respond. Something like 
if( . && /* condition */)

I wasn't trying to make it seem like flaming, and I dont think GhostAnime thought so. I was just stating that I felt a snap, and that I didnt just copy and paste the code like many new people do, which is quite flusterating. If you look GhostAnime appologized and said he/she was sleepy. So I dont know where your coming from. Besides isnt this a little off topic?

Thank you all for the information! I've pretty much finished it, thanks to your help. If you have any suggestions for changes to the last code I posted above please tell me. Also I just made a proc to make the monster return to your inventory, so the fix is unneeded to make the code above work on the "else if" part.
