Hello!

I've done everything according to the FPS tutorial and made myself an extension. When i try to call a function from unity i get this in the logs.

Code: Select all

I have no idea what am i doing wrong so please somebody help.

[appels]

when you send the 'chip' command it hit on this rule : ludis.corePoker.Table.AddChips(Table.java:110)

Somehting must be wrong there.

[Mastereve]

There all that AddChips() does is adding 20 to chipCount who is public and member of Player.

[appels]

whats on line Table.java:110 ?
It's hitting on it for some reason...

[Mastereve]

player.chipCount += 20;

Actually is this legal in Java? I am very new to it.

[appels]

so chipCount is known variable in the player class ?
maybe post the complete file if it's not to long

I wanted to see the other one, where it's getting the error in : Table.java:110

package ludis.corePoker;

      PokerPlayer player = getPlayer(fromUser);

   }
   
   public void processUpdateChipCount(User user) {
      
      PokerPlayer player = this.getPlayer(user);
      
      this.AddChips(player);
      extension.clientUpdateChipCount(player);
   }
   
   public void AddChips(PokerPlayer player) {
      
      player.increaseChipCountBy(20);
   }
}


I actually modified it a bit but still same error.

[appels]

Hard to tell but i'm guessing it's hitting on this function :

public void AddChips(PokerPlayer player) {

player.increaseChipCountBy(20);
}

does the 'increaseChipCountBy' function excist somewhere ?

[Mastereve]

Yes it's in player. Is there any API for writing stuff in the log so i can trace stuff around?

[appels]

You can use the trace command : trace ("my debug message");

Your saying that the function excists in the player class... pokerplayer class ?
because i can't see it in the scripts.

[appels]

yeah now it's in there, if that doesn't work you will need to trace the steps and see where it goes wrong.
The Code looks ok to me unless i missed something

[Mastereve]

Found what was causing this. I've traces player and it is null. For some reasons it does't get populated with information.

EDIT Found everything. Thnx for the help. This thread can be closed.
