Selecting a turf where the player is standing

Basically, I want to be able to edit a turfs contents that a mob is standing on (so I can delete stacking objects for a build code).

Thanks for the quick response.
Also, how do you search the contents to find if that type of object is already created? My current code is;

obj/build/Click()
    if(!togglebuild)
        for(var/obj/build/X in usr.contents)
            X.togglebuild=0
        usr << "You have selected [src]"
        togglebuild=1

        while(togglebuild)
            var/obj/O = new()
            var/turf/C = usr.loc
            O.icon = src.icon
            if(C.contents.Find(O))
                return
            O.loc = locate(usr.x, usr.y, usr.z)
            O.density = src.density
            sleep(1)
    else
        usr << "You have deselected [src]"
        togglebuild=0

I'm not following precisely what you're trying to do here, but I suspect you'd benefit from the locate() procedure. For example:

for(var/obj/build/X in usr.contents)
    X.togglebuild=0


is better written as:

X.togglebuild = !(locate(/obj/build) in usr.contents)


locate reference: http://www.byond.com/docs/ref/info.html#/proc/locate

Are you looking specifically for any subclass of /obj/build, or one that matches src.type?

obj/build/Click()
    if(!togglebuild)
        for(var/obj/build/X in usr.contents)
            X.togglebuild=0
        usr << "You have selected [src]"
        togglebuild=1

        while(togglebuild)
            var/obj/O = new()
            var/turf/C = usr.loc
            O.name = src.name
            O.icon = src.icon
            for(var/obj/B in C.contents)
                if(B.type == /obj)
                    del(B)
            O.loc = locate(usr.x, usr.y, usr.z)
            O.density = src.density     
            sleep(1)
    else
        usr << "You have deselected [src]"
        togglebuild=0


Basically, I am trying to prevent more than 1 turf-like object being on that turf at once. Without doing this, it will just continue placing objects down even when I'm standing still and that is unessessary. The if(B.type==/obj) code works, but it will become broken when I add items, and they are lying on the floor.

I see.

Assuming all of your 'turflike' objects are of type /obj/build:

mob
    var
        buildtype = null

    Move()
        .=..()
        if(. && buildtype) if(!(locate(/obj/build) in loc)) Build()

    proc/Build()
        if(!buildtype) return
        var/obj/o = new buildtype(loc)
        o.name = name
        o.icon = icon
        o.density = density

obj/build/Click()
    if(usr.buildtype)
        usr.buildtype = null
    else
        usr.buildtype = type
        if(!(locate(/obj/build) in loc)) usr.Build()


Completely untested. Will post explanation/fix bugs after dinner.

EDIT: Okay, thought about this slightly more, and you seem to have a player's-mob-passes-attributes-onto-construction paradigm for this thing that I'll attempt to emulate. Assume all 'turflike' objects are of type /obj/build:

mob
    var
        buildtype //We'll store the type of the object we're building in a mob variable
        
    Move()
        .=..() //Do the default Move() behaviour, and put the succeed/didn't succeed result into the variable '.'.
        
        if(.) //If we successfully moved...
            Build() //Then do some building
            
    proc/Build()
        if(!buildtype) return //If we're not building anything, just return
        
        if(istype(buildtype, /obj/build)) if(locate(/obj/build) in loc) return //If we're building a 'turflike' object and there's one in our square already, don't bother
        
        new buildtype(loc, src)
        
obj
    build
        New(loc, mob/m)
            .=..(loc) //Make a new object, put it on 'loc'
            
            icon = m.icon
            density = m.density //Set built object attributes
            name = m.name
    
        Click()
            if(usr.buildtype) //If we're already building something
                usr.buildtype = null //Cancel it.
            else
                usr.buildtype = type //Otherwise, set the buildtype and build on the turf
                usr.Build()


The advantage of this approach is that you don't have that infinite loop spinning all the time. And it should work for 'item-like' build objects when you throw those in.

Note that I'm not an expert on the building-game genre, and don't know quite how this is all supposed to work - this is mostly supposition based on your responses and the code you've shown.
