Satellite Dish Controller v2

Feature-rich single satellite dish script: fast automatic trader tracking, interrogation, and more! This script will automatically scan the sky for all visible trader contacts, locating them quickly with a modified gradient descent algorithm, and record traders and their positions in its internal stack for your use. It will interrogate each located trader if the dish is capable of doing so. This script is a rewrite of my older Satellite Dish Controller taking advantage of new features. It completely supersedes the old script in functionality, but it is not backwards-compatible if you use the advanced features of the older script. Usage d0: Satellite dish (any size) d1: (optional) Companion script (a user-provided IC for custom control) The dish is expected to be on while this script is running. The script will use the dish's max power setting during interrogation, and will attempt to conserve power otherwise. This script will not automatically call down traders, nor will it keep contacts visible in general to save power. You are recommended to place a separate vertically oriented dish for those purposes, or make use of this script's more advanced functionality. Advanced usage When this script first detects a new contact, it will attempt to yield control to the script located at d1 (see below), or directly enter tracking mode if no such script is found. During tracking mode, the script will continually update the following values in its internal stack: Address Value 10S The last known SignalID of the contact with ContactSlotIndex S 10S + 1 Current tracking state for the above contact (0: tracking, 1: located, 2: contacted/ignored) 10S + 2 The last known angle offset (in degrees) between the dish and the above contact, or -1 if unknown 10S + 3 The Vertical setting of the dish for the above angle 10*S + 4 The Horizontal setting of the dish for the above angle The ContactSlotIndex value S is provided by the game and takes the following values: ContactSlotIndex Trade
