yes i am having troub;e with some code for pac man. I am trying to make the ghost and i want you to transport to the lobby when touched by one,play lobby midi, and move randomly

heres what i have and it doesn't work. plz help

mob/ghosts/pinkGhost
icon = 'mob.dmi'
icon_state = "pinkghost"
Entered()
usr.PTS=0
usr.loc = locate(15,19,2)
usr<<"Sorry You lost all your points. Please try again"
usr<<sound('dw3castl.mid',1)
New()
walk_rand(src,7)
density = 0

Entered is not going to do it. Look up Bump() in the reference. Also, get rid of "usr"... doesn't belong in there anywhere.

Can we show me exactly i am not much of a wizard here and all the fancey words hurt my head

It's just a matter of swapping some words.

mob/player
Bump(var/atom/A) //called when player bumps into something
if(istype(A,/mob/ghost)) //if it bumped into ghost
PTS=0
loc = locate(15,19,2)
src<<"Sorry You lost all your points. Please try again"
src<<sound('dw3castl.mid',1)

ok like i did that exactly and made all the ghost names match and such but it would seem it doesn't work a blast

In response to RagnarofBurland
Oops, sorry about that. What I showed you would be if the player bumped into the ghost, not if the ghost bumped into the player.

mob/ghost
Bump(var/atom/A) //called when a ghost bumps into something
if(istype(A,/mob/player)) //if it bumped into player
var/mob/player/P = A
P.PTS=0
P.loc = locate(15,19,2)
P<<"Sorry You lost all your points. Please try again"
P<<sound('dw3castl.mid',1)

In response to English
P isn't defined. and i'm not sure how to!

In response to RagnarofBurland
Because you don't know what the ghosts are going to be bumping into (or at least I don't) you can't assume they will bump into a player. You have to use the checks I put in to make sure your only trying to effect players.

In this case P is just a temporary variable that I defined to let you treat what the ghost bumped into as a player (or whatever your default player mob is). One way to get arround doing that (but Spuzzum might not like it :p) is to just do it like this:

Bump(var/mob/player/P)
if(istype(P,/mob/player))
P.PTS = 0
//the rest like it was before

That will tell the compiler to assume what it's bumping into is a player.

You'll have to modify the types based upon what type your expecting the player to be in your game though.

Why not make a smarter ghost?
mob/Player
Ghost
    parent_type = /obj
    density = 1
    var
        mob/Player/target
        speed = 1 in 1 to 10
        dist as num
    Bump(var/atom/A)
        if(istype(A,/mob/Player))
            if(!A:client)
                world.log << "ERROR: [A] \[[A.type]] does not have a client."
                return
            spawn() alert(A:client,"Sorry, you've lost all of your points. Please try again!","Game Over")
            //A.client << sound('dw3castl.mid',1)
            del(A:client.mob)
    New()
        ..()
        while(1)
            sleep(11-speed)
            var/target_check = 0
            for(var/mob/M in world)
                if(M == target) target_check = 1
            if(target != null && target_check)
                if(dist == null) dist = 1e100
                else dist = get_dist(src,target)
                for(var/mob/Player/M in world)
                    if(get_dist(src,M) < dist + ((world.maxx + world.maxy/2)/10))
                        target = M
                        dist = get_dist(src,M)
                        break
                    else
                step_towards(src,target)
                if(get_dist(src,target) == target.density)
                    Bump(target)
            else while(!step_rand(src))

This ghost will select a target and, unless another player moves very close to the ghost, will relentlessly persue the target (instead of just walking randomly.) Good luck!

Ok i only have one problem lord of water. I just defined the PC as

mob
icon = "mob.dmi"
icon_state = "pacman"

how can i make this match your ghost bump code?
yes and when i add all my move and music play commands under the bump target i always get incorrect indentation!

aye yie yie time to go back to byond reference in a useless wallow of head pain

1 more thing! thank you for all the help. please still do what you can with the problem though because the code still is buggish

In response to RagnarofBurland
To make my code work, make the PC be /mob/Player instead of /mob. Also, I've updaded my code above to use your sound and message. Hope it works for you now!

ok well all the coding and such works now except i am getting words wierdest runtime error. Curse my rotten luck. i realize from the error its a density problem but whatcha gonna do

runtime error: Cannot read null.density
proc name: New (/testGhost/New)
usr: null
src: the testGhost (/testGhost)
call stack:
the testGhost (/testGhost): New(the ground (28,2,3) (/turf/ground))
RagnarofBurland logs out.
runtime error: Cannot read null.client
proc name: Bump (/testGhost/Bump)
usr: null
src: the testGhost (/testGhost)
call stack:
the testGhost (/testGhost): Bump(null)

In response to RagnarofBurland
You might want to show your proc /testGhost/New() here so that we can see what is wrong.
Apr 6 2002, 8:19 pm
In response to RagnarofBurland
Just a thought, with no code to see and all, but maybe you shouldnt set density to null, try setting it to 0.

In response to RagnarofBurland
hey i know this isnt a help thing but when do you expect to put your game out(cuz it sounds fun)

Bump(target)

//thats the code
