(See the best response by Lige.)
Code:


mob/proc
    Flying()
        if(ShipStateNum==0)
            ShipState="Rest"
        if(ShipStateNum==1)
            ShipState="Hover"
        if(ShipStateNum==2)
            ShipState="Flying"
    Speed()
        if(ShipSpeed==0)
            ShipSpeedStat="Stop"
        if(ShipSpeed==1)
            ShipSpeedStat="Slow"
        if(ShipSpeed==2)
            ShipSpeedStat="Medium"
        if(ShipSpeed==3)
            ShipSpeedStat="Fast"
mob
    verb //make hidden??
        EnterShip() //FIX LATER
        CheckShip()
            Flying()
            Speed()
            usr<<"You are at [ShipSpeedStat] speed and [ShipState] state."
        Stop()
            ShipSpeed=0
            ShipStateNum=0
            Flying()
            usr<<"EMERGENCY STOP EMERGENCY STOP EMERGENCY STOP. You are now at [ShipState] at [ShipSpeedStat] :[ShipSpeed]!"


Problem description: The result I get from using CheckShip(), CheckShip(), Stop(), Stop(), CheckShip(), Stop():
You are at speed and state.
You are at speed and state.
EMERGENCY STOP EMERGENCY STOP EMERGENCY STOP. You are now at Rest at :0!
EMERGENCY STOP EMERGENCY STOP EMERGENCY STOP. You are now at Rest at :0!
You are at Stop speed and Rest state.
EMERGENCY STOP EMERGENCY STOP EMERGENCY STOP. You are now at Rest at Stop :0!

However I'm suppose to be able to see Stop:0 instead of just 0 in the third and fourth line. What is causing this?

You're not calling your Speed() proc after changing the ShipSpeed var in the Stop verb.

Ah, lol I see what I did now. Ugh, I confused myself by switching the flying to different purposes while building it. It should have been CheckShip() instead of Flying(). While we're at it. I have a CheckParking var just above that. I'm trying to make CheckParking=1 below turf/Space/landingzone. However it keep saying reestablishing var as global or duplication of var. How do I fix this?

I'd need to see a code snippet to help you out. A few ideas come to mind, but I'm not sure how you're approaching this or what it is you're trying to do, exactly.

[in CoS.dm]
mob/var
    ShipParking=0

[in Vehicles.dm]
obj
    FlagCruiser
        Inside
            landingLevel
                ShipParking=1
                icon='FCIlandingLevel.dmi'

Alter the mob's var under the turf/object's behavior.

Example:

mob
    var
        my_var = 0

turf
    special_turf
        Entered(atom/movable/a)
            if(ismob(a))
                var/mob/m = a
                m.my_var = 1

        Exited(atom/movable/a)
            if(ismob(a))
                var/mob/m = a
                m.my_var = 0

obj
    neato
        proc
            change_mob_var(mob/m)
                m.my_var = !m.my_var
        Click()
            change_mob_var(usr)

Well this particular var was going to be used for if the ship is able to slow down to a hover. As for example if it's in outer space, low enough on a planet or in a flagship. I suppose I might be able to change it. However I don't understand why that var wouldn't work. A density var would, albeit it's a built-in var.

There's nothing wrong with the variable. It's that you are trying to apply the variable to the wrong object prototype.
