Click() & oview(1) in Developer Help

Sorry for more questions,

I seem to have come across a issue trying to get the Click() proc to work with oview().

Such as having to be next to the .obj to click it and have it function?

Is there a work around this? maybe I Should just use verb and set category to null then use a macro for objects..

Kind of at a loss I tried a few things looked at the Ref didn't get much and read a few guides in hopes maybe someone did it themselves then looked for a lib that had something similar to figure out how clicking a object next to the player works...

Click()
  if(src in oview(1))
    //do stuff

Yeah I tried that however
           Click()
                    if(src in oview(1)||src.open == 0)
                        src.icon_state = "door2"
                        src.open = 1
                        src.density = 0
                        src.opacity = 0
                    else if(src in oview(1))
                        src.open = 0
                        src.density = 1
                        src.opacity = 1
                        src.icon_state = "door1"


It works for the first click but closing does not work without oview(1) the thing works completely but from any range possible

Think a moment about what you're doing there.

If the NPC is in oview(1) OR the door is open
Do A
else If the NPC is in oview(1)

You're using OR. Even if src.open is a false value, the NPC will be in oview(1) of usr, and thus the else will never trigger.

if(!(src in oview(1))) return
// Make it simple. If the NPC isn't in user's oview(1), do nothing
if(!open)
  // open it
else 
  // close it

Okay I see, I tried to use Else if() so I could put arguments in there but I see where I was going wrong with what I thought it meant should have thought more about what I was doing.

                Click()
                    if(!(src in oview(1))) return
                    
                    if(!open)
                        src.icon_state = "door2"
                        src.open = 1
                        src.density = 0
                        src.opacity = 0

                    else 
                        src.open = 0
                        src.density = 1
                        src.opacity = 1
                        src.icon_state = "door1"



I have it down like this now I was a bit confused when I read the operators guide for ! , thanks to you I understand how (!) works now

May I ask one more question? if you dont mind?

It's a free forum, go ahead.

And about the ! operator, it's used to check every false value ("", null, 0), and is used to check TRUE/FALSE values, such as your "open" variable.

if(open)
// if "open" has a true value
//such as 1 or a text string (not-empty)

if(!open)
// if "open" has a false value.
// such as an empty text string "", null, or 0.

In response to Emasym (#6)
I didn't take full advantage of (!) here either... but my main issue is

When you have a item equipped your unable to Drop any item? and that was making a if statement to check if the player has something equipped? and now I cant drop anything pretty much until I un-equip a item...

obj/items/
verb/get()
set src in oview(1)
src.loc = usr
verb/drop()
if (!usr.EQW)
usr << " You must take it off before you can drop it"
src.loc = usr
else
loc = usr.loc


I see the problem but how do I make it allow me to drop items below the tree of obj/items avoiding it counting every item as stuff under .EQW

You set the value of EQW to that item, and on Drop() you check whether EQW equals src (the item being dropped).

obj/items
  verb/Equip()
    if(usr.EQW)
      usr<<"You un-equip [usr.EQW]"
    usr.EQW=src
    usr<<"You equip [src]"
  verb/Drop()
    if(src==usr.EQW)
      usr<<"You've got that equipped!"
    else loc=usr.loc

Is this equip() verb setup to Unequip and Equip at the same time What is usr.EQW=src doing exactly?
#10 May 2 2010, 2:05 am
In response to DeathBane (#9)
It wasn't meant to equip/unequip, just to equip. But in case there was something equipped, it'd unequip that. It's a very simply system, nothing complex.

A verb doing both would be something like;

verb/Equip()
  if(!usr.EQW)
    usr.EQW=src
    usr<<"Equipped [src]"
  else if(usr.EQW==src)
    usr.EQW=null
    usr<<"Unequipped [src]"


The unequip will only work if you Equip() the exact item you've got equipped.
I wouldn't recommend such a system, because it's just confusing.

yeah just as you were posting I messed with it and did something that does both will problems occur later with it?

obj/items/equip/
    verb/equipw()
        set name = "Equip"
        if(usr.EQW)
            usr<<"You unequip [usr.EQW]"
            src.suffix= ""
        else
            usr.EQW=src
            usr<<"You equip [src]"
            src.suffix = "Equipped"


I can drop items normally even when stuff is equipped now though so it is working just not sure if I should be avoiding stuff like this (was told Shortcuts are normally bad in programming

In response to DeathBane (#11)
Well, you're not setting usr.EQW to null when unequiping, so that's one problem.

Another "problem" would that that, no matter which item you use Equip() on, if you've got something equipped, it'd unequip it.

And what do you mean by "Shortcuts" ?

I added usr.EQW= null to unequip

also the way its working it does not seem to be unequipping
the suffixes still switch which makes me think they are set on the right usr.EQW=src or usr.EQW= null

anyway I can check?

also just what i heard from a friend on msn told me, he said shortcuts in programming is bad because you want the code as flexible as possible sometimes longer is better...

(is the F1 Ref in the Dream-maker good to use also?)

Everything combined
mob/var/obj/EQW // object variable

obj/item/verb
 Drop()
  set src in usr.contents
  if(src!=usr.EQW)
  loc=usr.loc

 Get()
  set src in oview(1)
  loc=usr

 Equip()
  set src in usr.contents
  if(usr.EQW)
   usr.EQW.suffix=""
   usr<<"You unequip [usr.EQW]"
   usr.EQW=null
  else
   usr.EQW=src
   src.suffix="Equipped"
   usr<<"You equip [src]"

That is rather flawed logic though.
Instead of explicitly returning if the condition is NOT meet, why not simply keep things modular and call the object's function if the condition is meet, then handle everything else in that object's function.

Something as simple as
Click()
    if(src in oview(usr, 1))
        activate()

With the door's activate defined as
activate()
    density = !density
    opacity = !opacity
    icon_state = "door[denisty]"


Now you can handle the same functionality for multiple objects.
