Events

All the scripts under events group are called when something happens

For example:

• pn_on_player_join is called when a player (included yourself) joins the lobby.
• pn_on_player_quit is called when a player (included yourself) leaves the lobby.

Tips

• Create an object that lists all the available games online and allows to join
• Create a button to host a new game
• use pn_send to send messages with an id of your choice
• with pn_send you can send a string a number or an array
• inside the script pn_on_receive use a switch statement to handle the messages
• don't send too much data, this library uses HTTP connection / mysql database, to avoid performance issues.
