You will find a functions reference in the readme.txt in the zip of the dll.
You can also download the source of the "game" that I used to test the plugin
It demonstrates the following:
a) establish connections (interact with object on which Roger is standing at the beginning)
b) transmit player character coordinates (NPC SHADOW is put to the received coordinates)
c) transmit a string (the locationname at the current mouse position is sent)
d) transmit an integer (the object shape at Roger's position is sent, so that the picture is updated)
For local testing use 127.0.0.1 as ip. Then the NPC will act like Roger's shadow and follow him whereever he goes. The status line will tell the object name under your current mouse pointer position. The first 2 pictures will show the same shape like that on which Roger is standing or walking over.
b) and c) aren't designed for use with multiple connections. For a single connection to another test game the NPC will show the other player's position, the upper left picture will show the shape at this position. The status line will tell the locationname at which the other player is pointing with the mouse.
For more questions, please feel free to ask everybody except me
: It's not like "one click and your game is a network game". There's a lot of scripting to be done. And there are still questions how to handle possible synchronization problems.
