Custom Dvars in Scripting

Created on: January 07, 2017, 07:06:44 am

How do you make a custom dvar?

When I run this code it crashes my game.

Code Snippet

Plaintext

function bank()
{
    players = GetPlayers();
    for (i = 0;i<players.size;i++)
    {
        players[i].balance = players[i] GetDvarInt("bank_points", 0);
    }
    
    level thread deposit();
    level thread withdraw();
}

I'm trying to use it to make a bank that saves your points between games but I can't get it to work.

Help fixing the dvar or any other way to save a variable between games would be greatly appreciated.

prob coz your "getting" a dvar that doesnt exist "before setting" it then trying to use it

also i believe GetDvar is global, so shouldnt be used "on" a player

Dvars are different in Black Ops 3. The number after the dvar name, in this case 0, is the default value to set the dvar if it doesn't find it.

I think this is the problem I was having because this code works:

Code Snippet

Plaintext

function bank()
{
    level.balance = GetDvarInt("bank_points", 0);
    
    level thread deposit();
    level thread withdraw();
}

Now I just have to figure out how to get it to work with individual players.

Also, are dvars supposed to save when you completely close the game? Does this only happen in the mod tools or in the regular game too? Right now it only saves when you leave the map and start the map again without closing the game.

youd need getCLIENTdvar for that, but according to the api that doesnt exist, previously this has only worked for host or via csc so im guessing at least for now thats still the case

Code Snippet

Plaintext

could do getDvarInt( "bank_player_" + int, "0" );

or something and track the players with "int"

i believe the old ugx mod did something similar back in the old days

Now when I set the dvar it sets it to 1000 and then it immediately goes to zero:

function bank()
{
    players = GetPlayers();
    for (i = 0;i<players.size;i++)
    {
        GetDvarInt("bank_player_" + i, 0);
        players[i].order = i;
    }
    
    level thread deposit();
    level thread withdraw();
}

function deposit()
{
    trig_depo = GetEnt("deposit_trig","targetname");
    trig_depo SetHintString("Hold ^3[{+activate}]^7 to Deposit into Bank[Amount:1000]");
    trig_depo SetCursorHint("HINT_NOICON");
    while(1)
    {
        while(1)
        {
            trig_depo waittill("trigger", player);
         
            if (player zm_score::can_player_purchase(1000))
            {
                player zm_score::minus_to_player_score(1000);
                SetDvar("bank_player_" + self.order, GetDvarInt("bank_player_" + self.order)+1000);
                IPrintLn("Deposited $1000(New Total = " + GetDvarInt("bank_player_" + self.order) + ")");
                player PlayLocalSound("purchase_accept");
            }
            else
            {
                player PlayLocalSound("purchase_deny");
                IPrintLn("Not Enough Money");
            }
            break;
        }
        wait(0.25);
    }
}

function withdraw()
{
    trig_with = GetEnt("withdraw_trig", "targetname");
    trig_with SetHintString("Hold ^3[{+activate}]^7 to Withdraw From Bank\n[Amount: 1000][Fee: 100]");
    trig_with SetCursorHint("HINT_NOICON");
    while(1)
    {
        while(1)
        {
            trig_with waittill("trigger", player);
            
            if (GetDvarInt("bank_player_" + self.order) >= 1000 && player zm_score::can_player_purchase(100))
            {
                player zm_score::add_to_player_score(1000);
                SetDvar("bank_player_" + self.order, GetDvarInt("bank_player_" + self.order)-1000);
                IPrintLn("Withdrew $1000(New Total = " + GetDvarInt("bank_player_" + self.order) + ")");
                wait(0.01);
                player zm_score::minus_to_player_score(100);
                player PlayLocalSound("purchase_accept");
            }
            else if (player zm_score::can_player_purchase(100))
            {
                player PlayLocalSound("purchase_deny");
                IPrintLn("Not Enough Money");

            else

                IPrintLn("Insufficient Funds(Total = " + GetDvarInt("bank_player_" + self.order) + ")");
            }

self.order

Should be:

player.order

I got it to work finally. I changed the order variable to use the player's name because that works better if you play a game with someone else. The name_split parts are to get it to work with a guest account because the space in the name messes with the dvar. I have one more question, do dvars usually save their values after the game is closed completely?

No they dont, you can try and use

Code Snippet

Plaintext

SetSavedDvar( <dvar>, <value> );

and otherwise you have to use stats to be able to save it between games.

EDIT:
one thing you might want to think about: dvar's can be very easily changed by the player using the console ( not sure about a saved-dvar, but i think as well ). Easy way to get points

I couldn't find "SetSavedDvar" in the BO3 API.

How do you use stats?
