Friends ArrayList

[MyMommyLovesMe]

Hello MinecraftForge, can you please help me? If you can do it yourself that would be wonderful but I'm trying to get the Player's IGN once you hit them. Is there a way of doing that.

 

OBJECTIVE:

If you a hit player it will add them to a ArrayList called "Friends" once you hit another player it will clear the ArrayList and add the other player, so my idea is like

 

if(Player is hit)

Friends.clear();

Friends.add(Player's Display Name);

To get access to when Player1 hits Player2, I would recommend you subscribe to the LivingHurtEvent and check if both attacker and victim are players, along with whatever other parameters you require.

 

You can get access to the Player's display name from Entity#getDisplayNameString. (Player's extend Entity.)

If you are going to do anything with that however, for example saving it, to compare later, I would heavily recommend you use the UUID instead, and simply translate it to the Player's name from the UUID. If the player ever change his name, a name-dependent system will break.

Nah, Its not going to be permanent once you close MC and reopen its suppose to not save or do anything, everything is reset, its just temporary friends. I wouldn't need anything to worry about changing names Probably should've mentioned that...

1. Version?

2. Sided mod (present on server) or client-only?

3. Should friend list be ever saved (quit/join world/server)?

4. The logic you described:

 

if(Player is hit)

Friends.clear();

Friends.add(Player's Display Name);

 

...will end up with List being of size == 0 or 1. Is this desired outcome? If yes - don't use List. Make direct reference to EntityPlayer (or null).
