[1.14.4] [Solved] Persisting player health on dimension change


FireController1847

Recommended Posts

I'm currently working on a mod that allows a player to have more than their maximum amount of health. I've got the health modifier down, but what I don't understand is what happens when the player changes dimension. It appears that the modifier goes away. This would be fine, except... well, this is best explained with an example: Let's say I have 20 hearts. If I'm at full health, then go through a nether portal, my modifier is re-applied and I get the appropriate amount of 20 hearts back. However, my health is down to 10. My question is, how do I remember and persist the player's health as they go from one world to another?

 

My code is currently available here, and below is a code snippet of my changed dimension event:

@SubscribeEvent
  public static void onPlayerChangedDimension(PlayerChangedDimensionEvent event) {
  debug("PlayerChangedDimension{Event}");

  // Fetch Capability
  PlayerEntity player = event.getPlayer();
  IMoreHealth cap = MoreHealth.getFromPlayer(player);

  // Re-add health modifier
  LevelHearts.applyHealthModifier(player, cap.getTrueModifier());
}

It worked! Awesome, thank you!

 

I don't suppose you'd be willing to help me understand what this piece of code does? I kind of get that it's making a packet for the attribute, but what is this "sendToTrackingAndSelf" method?

It sends the packet to all players whose clients are tracking the entity (i.e. all players within X blocks of it) as well as the entity itself (if it's a player).

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

So in reality, what's happening is the attribute is lost on the client-side but not on the server side, which allows it to recover itself without having to re-initiate it?

Yes. The client loses the attribute (which may be a Vanilla bug, I'm not sure), but the server retains the correct value and re-syncs it to the client.

    • If you are using AMD/ATI, check for driver updates on their website - do not update via system
    • Hi, Create a new class that extends "Block" class and you need json for it in resources/assets/modid/blockstates directory and resources/assets/modid/models. You can generate json for it using a tool like misodes model generator. Here, atleast, are blocks explained at forge docs.  Don't forge to look at vanilla code, like Magma Block is a good reference if you're trying a "green fire block".  Modid should be replaced with your actual forge mod namespace!
