[TF2] Real-Time Strategy Camera Controls

AI_ · **Author**

This is a proof-of-concept implementation for a Real-Time Strategy (RTS) camera control setup with support for screen-space to world-space point-and-click selection. It is written in pure SourcePawn and only requires SourceMod running on a Team Fortress 2 server.

Please note the cursor and other movement speeds and sensitivity settings have been hard-coded and should be edited and configured for your implementation. Users may also have specific preferences that depend on game settings and server latency.

Custom bots used during testing and demonstration are not part of this release.
