Minor As discussed in this SpigotMC thread, when using either ChunkPopulateEvent or ChunkLoadEvent and checking for mob spawners being created/existing and trying to replace it with another material, it sends this warning into the logs:
[07:52:10 WARN]: Tried to load a DUMMY block entity @ BlockPosition{x=186, y=37, z=327} but found not block entity block Block{minecraft:diamond_ore} at location
[07:52:10 WARN]: Tried to load a block entity for block Block{minecraft:diamond_ore} but failed at location BlockPosition{x=186, y=37, z=327}
These are the two pieces of code used:
@EventHandler
public void onChunkPopulate(final ChunkPopulateEvent e) {
final Chunk chunk = e.getChunk();
for(BlockState blockState : chunk.getTileEntities()) {
if(blockState instanceof CreatureSpawner) {
blockState.getBlock().setType(Material.DIAMOND_ORE);
}
}
}
@EventHandler
public void onChunkLoad(final ChunkLoadEvent e) {
if(e.isNewChunk()) {
for(BlockState tileEntity : e.getChunk().getTileEntities()) {
if(tileEntity.getBlock().getType() == Material.SPAWNER) {
final Location location = tileEntity.getLocation();
tileEntity.getBlock().setType(Material.AIR);
}
}
}
}
