Join cmd execute

What is the line code to un a commande when a player join the gamr

Look at the code for JoinCommands by @PixelGuy75. The code is simple to understand(especially for you).

I did look at the code put i want to run the comande /colored when a player join

I have no choice now but to tell you to learn PHP, and the PocketMine API.

Its just to have colored text is only 1 line

Try to add § + color ID in the message configuration
Example: " §aHello player!"
(The message should be green)

My idea was without editing the source code. I didn't try JoinCommands but I think that commands and messages can be edited from configuration file.
I think editing source code is not needed for colored messages
