Using Waypoints in Game

ID:2904086

Project Overview:
So in this Game, the map of the Game is the map of another Game.... Players can move the Camera all across the Map, but the can't actually move their Player unless they set a WayPoint...
I am a really noobie person with some aspects of BYOND...
I want to create a WayPoint that only the player will see.
Code:
obj
     WayPoint
          icon = 'WayPoint.dmi'
mob
    var
          WayPointLocation

mob/verb/setWaypoint()
    set name = "Set Waypoint"
    usr.WayPointLocation = usr.loc
    usr.WayPointLocation += new /obj/WayPoint
    


mob/verb/removeWayPoint()
    usr.WayPointLocation = null
    usr.WayPointLocation -= new /obj/WayPoint


mob/verb/toggleWayPoint()
    if(!usr.Waypoint)
        setWaypoint()
    else
        removeWayPoint()


Problem description: Compiles properly but it doesn't allow me to place a WayPoint on the map... Has an error for usr.loc being src...

Also, I don't know how to make it a multiple instance in which 10 different clients would each have their own WayPoint and not see each others WayPoint.

Sorry for having no clue on where to start.

Tried to improve my code:

mob/player/var/WaypointActive = 0
mob/player/var/target_loc
mob/player

    verb/SetWaypoint()
        var/obj/waypoint/W = new
        src.WaypointActive = 1
        W.set_target_loc(locate(x, y, z), usr)
        src.target_loc = W.target_loc

    verb/RemoveWaypoint()
        var/obj/waypoint/W = locate()
        src.WaypointActive = 0
        target_loc -= W

    proc/UpdateWaypointVisibility()
        for(var/obj.waypoint/W in world)
            if(W.owner == usr)
                if(src.WaypointActive == 1)
                    W.target_loc += W
                else if(src.WaypointActive == 0)
                    W.target_loc -= W
            else
                return 1


There are no errors and the code looks clean but it doesn't do anything and doesn't throw an error in the game until I click remove waypoint (Create Waypoint does nothing and throws no errors)

Sorry for blowing up my own Post...
I realized I hadn't done it correctly...
So I attempted to fix up my code...

// mob/player.dm
mob/player/var/WaypointActive = 0
mob/player/var/target_loc
mob/player

    verb/SetWaypoint()
        var/obj/waypoint/W = new
        src.WaypointActive = 1
        W.target_loc(locate(x, y, z), usr)
        W.target_loc = src.loc
        UpdateWaypointVisibility()
        

    verb/RemoveWaypoint()
        src.WaypointActive = 0
        UpdateWaypointVisibility()

    proc/UpdateWaypointVisibility()
        for(var/obj.waypoint/W in world)
            if(W.owner == usr)
                if(src.WaypointActive == 1)
                    W.target_loc = new(W)
                else if(src.WaypointActive == 0)
                    del(W)
            else
                return 1


Now it doesn't throw an error on compile and when I use either SetWaypoint() or removeWaypoint() the both do not throw an error inGame but there is nothing happening from these verbs, it should be putting a blip on the map...

It does nothing but doesn't throw a single error...

obj
     WayPoint
          icon = 'WayPoint.dmi'
          var/xobj=3
          var/yobj=3
          var/zobj=3

            WayPointLocation=W
            contents+=W


mob/verb/removeWayPoint()
    usr.WayPointLocation= initial(usr.WayPointLocation)


mob/verb/toggleWayPoint()
    if(!usr.Waypoint)
        setWaypoint()
    else
        removeWayPoint()

I made my version

I got it working the way I wanted:

// mob/player.dm
obj/WayPoint
    icon = 'MAP/Waypoint.dmi'

var
    WayPointLocation = 0

mob/player
    var/tmp
        obj/WayPoint

    verb/setWaypoint()
        set name = "Set Waypoint"
        if (!WayPoint)
            WayPoint = new /obj/WayPoint
        WayPoint.loc = locate(usr.x, usr.y, usr.z)
        WayPointLocation = 1
            
    verb/removeWayPoint()
        if (WayPoint)
            WayPoint.loc = locate(1, 1, 1)
        WayPointLocation = 0
        
    verb/toggleWayPoint()
        if (!WayPointLocation)
            setWaypoint()
        else
            removeWayPoint()

I believe loc will return to null in load game. Because this var is reference, to call and use. You can storage the obj is contents, then it be restaured in the world with the player. I know 2 ways, seccond could be a world savefile with all obj. You can give this obj, in creation person, we will live forever.
