Solved Light update

I use $level->setBlock() to set blocks (for example, world editor).
But when I set blocks, the light update is broken.
I've turned on the light update function in server.properties and pocketmine.yml already.
So I want to use codes to do that.
After $level->setBlock(), how to update light using codes ?
Thanks for your help.

 

Level->updateAllLight(Vector3 $pos);
