[1.10] Spawning an entity with ForgeData


Recommended Posts

My custom mob spawner (now rewritten to not extend vanilla mob spawners in any way) is spawning mobs.

However, the data I set to the mobs (via ForgeData), when they're spawned via the server, is not synced with the client. Here's the log I'm generating when mobs spawn:

[02:09:43] [Server thread/INFO] [STDOUT]: [com.kallgirl.souls.common.block.Summoner.SummonerLogic:updateSpawner:139]: set entity data
[02:09:43] [Server thread/INFO] [STDOUT]: [com.kallgirl.souls.common.NoMobSpawning:onMobJoinWorld:27]: successful spawn: Pig
[02:09:43] [Client thread/INFO] [STDOUT]: [com.kallgirl.souls.common.NoMobSpawning:onMobJoinWorld:30]: mob had no data: Pig


How can I ensure that the custom data I set on the entity, when spawning it, is also set on the client entity that is spawned?


By printing the stack trace I was able to find where the entity enters the client, but it seems like the code (NetHandlerPlayClient:961) doesn't have support for forge's ForgeData. Is this a bug, an oversight, or am I doing something wrong/missing a step?

The ForgeData tag has never been automatically synced. If you want the data available on the client, you need to sync it yourself.


That said, you shouldn't need it on the client. Cancelling EntityJoinWorldEvent on the server will prevent the entity from being sent to the client at all.
