Ok so Im making a market system in my game where players can make stuff with their job and then sell it to other players. I have it set up where they put the item up on the market at a certain price. And then all other players can view it.

What I cant figure out how to do is display all items on the market to a buyer and allow them to choose an item. I was thinking of making a pop up grid and that would display all the information, but not sure how to do the verb so they can only see the buy verb when looking at this grid.

Make it so theres a wall/desk/something with density blocking the buyers from the obj
obj/Fine_Jewelery
    icon='Fine.dmi'
    icon_state="Jewelery"
    var/sellprice=2000
    var/owner
    var/forsale
    verb/ForSale()
        if(src.forsale==1)
            src.forsale=0
            usr << "[src] is no longer for sale!"
        else
            src.forsale=1
            usr << "[src] is for sale!"
            
    verb/Buy()
        set src in oview(2)//if you put it behind glass, they can pick it up
        if(src.forsale==1)
            switch(alert("Would you like to buy [src]","Purchase?","No","Yes"))
                if("Yes")
                    usr.contents += new/obj/Fine_Jewelery
                    usr.gold -= src.sellprice
                    src.owner= "[usr.name]"
                    del src
        else
            usr << "This [src] is not for sale!"
            return
            
    verb/Get()
        set src in oview(1)
        if(src.owner==null)
            src.Move(usr)
            src.forsale=0
            owner= "[usr.name]"
            view() << "[src] belongs to [usr]"
        if(src.owner==usr.name)
            src.forsale=0
            src.Move(usr)
            view() <<"[usr] got their [src]"
        else
            src.forsale=0
            src.Move(usr)
            view()<<"[usr] picked up [owner]'s [src]"
            src.owner= "[usr.name]"

Actually that isnt exactly what I was refering too. They arent gonna be anywhere near the actual object they are just gonna see a list of items and select what they want to buy.

But i figured out a way, i used the click command and added it to a grid so when they click on it in the grid it ask them if they want to buy it. But thanks for the input

Also remember that checking boolean vars (true or false) is better than using ==1 or ==0/null/"".

Something like this could work:

mob/verb
    show_market_window()
        if(!client) return
        winshow(src, "myMarketWindow")
        verbs += new/mob/verb/buy //window is visible, so show the verb
        verbs += new/mob/verb/hide_market_window
        verbs -= /mob/verb/show_market_window
    hide_market_window()
        if(!client) return
        winshow(src, "myMarketWindow", 0)
        verbs -= /mob/verb/buy
        verbs += new/mob/verb/show_market_window
        verbs -= /mob/verb/hide_market_window
    buy()
        if(winget(src, "myMarketWindow.is-visible") != "true") verbs -= /mob/verb/buy //hide the verb if the window has been closed
        ...

mob
    //hide the verb
    New()
        . = ..()
        verbs -= /mob/verb/buy
        verbs -= /mob/verb/hide_market_window
    Logout()
        verbs -= /mob/verb/buy
        verbs -= /mob/verb/hide_market_window
        return ..()


Only add the verb if the player is viewing the window. You could also prevent players from closing the window by disabling it in the interface and making your own close button, which calls hide-market-window.

Can't the window be closed by ALT-F4, regardless, though?
