I'm currently in class and, rather than paying attention, decided to work on a Capture the Flag script. I just tested this by putting the flags on a basic map with crappy grass turfs and a circle for the player.. bla bla bla. Unfortunately, Entered() isn't being called when I actually enter. I read the documentation on Entered() and... yeah. I'm starting to wonder if I overlooked anything.

// CTF.dm
// This script handles the capture the flag
// game.

var/obj/GameObjects/CTF/Flags/Flag = new('Flag.dmi', "Flag")

mob/attackable/player
    var
        team = "red"
        obj/GameObjects/CTF/Flags/Flag/takenFlag

    proc
        GiveFlag(obj/GameObjects/CTF/Flags/Flag/f)
            src.overlays += Flag
            takenFlag = f
            //slow the users speed here

        TakeFlag(scored = 0, mob/attackable/player/p)
            src.overlays -= Flag
            if(!scored)
                src.takenFlag.GiveFlag(p)
            else
                src.takenFlag.GiveFlag()

            src.takenFlag = null

obj
    GameObjects
        CTF
            Flags
                Flag
                    var/taken = 0
                    var/score = 0
                    var/team = ""
                    layer = MOB_LAYER + 1
                    icon = 'Flag.dmi'
                    icon_state = "Not Taken"

                    Entered(mob/attackable/player/O) // Originally just O.. I just breifly tried changing the type of the var
                        if(istype(O, /mob/attackable/player))
                            var/mob/attackable/player/p = O
                            if(p.team != src.team && !src.taken)
                                src.TakeFlag(p)

                            if(p.team == src.team && p.takenFlag)
                                src.ScoreFlag(p)

                    proc
                        GiveFlag(mob/attackable/player/p)
                            icon_state = "Not Taken"
                            taken = 0
                            if(p)
                                world << "[p.name] has [(p.team == src.team) ? "returned the flag to [src.team]." : "scored [src.team]\'s flag for [p.team]."]"

                        TakeFlag(mob/attackable/player/p)
                            icon_state = "Taken"
                            taken = 1
                            world << "[p.name] has taken [src.team]\'s flag."
                            p.GiveFlag(src)

                        ScoreFlag(mob/attackable/player/p)
                            p.takenFlag.GiveFlag(p)
                            p.TakeFlag(1)
                            src.score++

I think you want Crossed() instead. Entered() is called for movable objects when something is placed in its contents, not when they step on/in it.

I always thought Entered() was still possible of checking if something is inside of it. *shrugs* I know crossed will do the job though. Haven't tested it but it should work flawlessly. Thanks.

You're not inside a bag if you're standing on top of it, right?

Enter/Entered are called when something is added to the source's contents, while Exit/Exited are called when something is removed from the source's contents. Idea for creating a stackable items inventory system.

If it's a bag of holding, you are never technically inside of it. You are actually in a parallel reality.

Anyway, Enter/Entered() are only called when you actually call Move(). It's not triggered by any other means of adding to contents. Be mindful of this.

This is part of why I never recommend setting locations manually, because you can't rely on accurate Entered()/Exited() parity.
