Countdowns and Players

Hey there!

I am currently developing a Survival Games Plugin.
Everything works fine, but when i try to make a Countdown like:

10
9
8
7
...

I did the code like this:

$this->api->chat->broadcast("10");
sleep(1);
$this->api->chat->broadcast("9");
sleep(1);

and so on. But when i test it ingame it says "Starting Game..." and
waits for ten seconds. Then it posts erverthing at the same time.
Everything else is working!

Also, i have got another question.
I already have a "spawn" listener.
This listens for when a player spawns, right?
How can i get the name of the person who spawned?

I hope some of you can help me with my problems!

Thanks!

He also needs to make a public variable to store the number. I suggest PocketMine Team to make a schedule remove API or I made it by myself.

Yes you can remove it with:
$server->query("DELETE FROM actions WHERE ID = ".$id.";");

But I think I also need to remove the schedule from the array in the code.

It should work fine, but the only problem is the id.
You can't use the traditional $this->api->schedule() because you can't get the id then.
you need to insert it in the actions table from the database manualy

I saw $this->api->schedule() returns the ID in Array, I mean I may need to do unset().

Oh the schedule function returns the id.
so it's easy:

PHP:

$id = $this->api->schedule(); // to make a scheduled task

$server->query("DELETE FROM actions WHERE ID = ".$id.";"); // to remove it

Lol, SQL thingy.
