A Practical Example of IPC
Since the last examples were a bit simple, I wanted to go ahead and make a script that used IPC in a cool way. Well, not to toot my own horn, but I fucking delivered; and i'm open sourcing it. This script is far from perfect, but its a good start, and I took care of all the complex math already.
The purpose of this script is to run up to 20 drones around the map that will mimic the exiva's casted by the main player, and communicate that data back to said player. All of the results will display on a HUD, showing things like "very far to the east of thais" or "far south of venore". If any of the drones encounter the target player (readas: if he's close by, next to the drone, or above/below the drone), the script will say something like this in the server log:
The target player is near "My Exiva Dude 3" in "Thais".
If the target player is far or very far from all of the drones, though, some magic takes place. The script will use some moderately advanced trigonometry to triangulate the position of the player, based on the areas from each exiva. It does this by calculating a region that the target player MUST be inside of. From there, it looks at a list of known towns and hunting spots (thanks to @Rydan, @Fatality, and @kimse for helping me with these lists) in that region, and tells you the top six locations where the player might be. If there's no known locations inside of the area, it will tell you the center xy position and the outline of the polygon, so you can take a look at the data on tibia.xyz or another mapping site. If all else fails, you will still have a large list of exiva results to help locate the player on your own.
Before I jump in to the actual code, I'd like to note that me and @kimse have determined the optimal locations for each drone without the need for PACC: Thais Bless, Folda Boat, Carlin Temple, Kaz North, Ab Boat, Demon Oak Reward, and Venore Boat. If you exiva from either Darashia Carpet or Darashia Boat on the main character, this will cover the entire map very well.
With further talking, here's the code.
