Block & Entity Hooks

BlockEntityHooks​

dev.architectury.hooks.block.BlockEntityHooks

BlockEntityHooks.syncData(myBlockEntity);

syncData(BlockEntity) pushes a block entity's current data to nearby clients (it marks the block as changed so the server resends it). Call it after changing data you want clients to see.

Server-side only

syncData throws if called on the logical client. Guard with if (!level.isClientSide()) { ... } first.

EntityHooks​

dev.architectury.hooks.level.entity.EntityHooks

@Nullable Entity entity = EntityHooks.fromCollision(collisionContext);

fromCollision(CollisionContext) returns the entity behind a collision context (for example, inside Block#getCollisionShape), or null if there isn't one.

PlayerHooks​

dev.architectury.hooks.level.entity.PlayerHooks

if (!PlayerHooks.isFake(player)) {
    // a real player, not a fake/automation player
}

isFake(Player) reports whether a player is a "fake" player (such as those some automation mods use). Handy when you only want to react to genuine players.

ItemEntityHooks​

dev.architectury.hooks.level.entity.ItemEntityHooks

IntValue lifespan = ItemEntityHooks.lifespan(itemEntity);

lifespan(ItemEntity) returns the item entity's lifespan as an IntValue you can read (and, on NeoForge, modify). On Fabric it's a read-only value of 6000.
