I've been trying to make a player respawn with a certain potion effect active, using the Forge PlayerEvent.Clone event. However this is only called on the server-side, so when my potion effect is added, the effect takes place, but it doesn't show in the inventory on client-side. I've tried to resolve this by sending a message (implementing IMessage) to the client, on which this method is called:

Minecraft.getMinecraft().thePlayer.addPotionEffect(new PotionEffect(3, 9000, 0));

However, for whatever reason this does not work. It doesn't make any difference to the outcome.

 

What I'm really asking is more of a general question, not necessarily limited to the player respawn event. How does one let the client know that a potion effect has been applied, when it was applied only on the server side, for whatever reason? Must one use some sort of vanilla packet, or am I missing something stupidly obvious? Any help is much appreciated.

Thank you. With the PlayerRespawnEvent it works. But why doesn't the PlayerEvent.Clone work, just out of interest?

OK. Cheers for the help!
