I have made a script that takes the SetHintString() and makes it a Hud instead. My hud shows up with Press and hold &&1 to, blah blah blah, so I want to change that to the players use button. I have been trying to parse the string by turning it into tokens and then concatenate it back together, but StrTok with not work on this:

    &"ZOMBIE_WEAPON_PPSH_2000"

If I print
If I change the above to something like "Press &&1 to buy ppsh", then I am only left with trying to figure out what the users USE button is. I tried:

    usekey = getKeyBinding("+activate");

but am having no luck with that either.

I can get a string, that I pass in, to parse and I replaced &&1 with USE, but this isn't really what I set out to do.

    //I thread FixHint("Press &&1 to buy ppsh") and it works like I want except for use button.

    FixHint(hint_string){
        tokens = StrTok(hint_string," ");
        new_hint = "";
        for(i=0;i<tokens.size;i++){
            if(tokens[i] == "&&1"){
                new_hint = new_hint + " USE";
            }else{
                new_hint = new_hint + " " + tokens[i];
            }
        }
        return new_hint;

    }

Above comes out, Press USE to buy ppsh, for the strings, but when it is &"ZOMBIE_WEAPON_PPSH_2000", it crashes the map to the menu screen and says Error: Attempted to overrun string in call to va().

Lastly, I was trying to use:

player isLookingAt(trigger);

but it kept return 0, even when I was looking at the trigger. Any help with a function that works like that one sounds like it should, or what I may be doing wrong?

Press [{+activate}] to blegh.
Edit: That string error, have you precached the string as well as set it in a str file and then included in your map's ff patch?

    hint_string = get_weapon_hint(self.zombie_weapon_upgrade);

   //which returns
   return level.zombie_weapons[weapon_name].hint;

    add_zopmbie_weapon("zombie_ppsh", "Press and hold &&1 to buy PPSH [Cost: 2000]", 2000, "vox_ppsh", 5);

    StrTok(hint_string, " ");

y are u trying to make it a hud? isnt a hintstring good enough?
