Hello everyone and welcome to a new (probably short) series of videos I do involving the source code from Valve for Half-Life 2, and some guides on how to do stuff with this code. In this episode, I followup on the full holster sequence tutorial I did a while ago by resolving an issue that I talked about at the end of the tutorial, while also fixing some issues that I didn't realize existed. These issues include the Gravity Gun's effects being present on other weapons, weapon viewmodels disappearing when grabbing then dropping physics props repeatedly, performing attacks when throwing physics props and glitchy reload animations when switching weapons. I outline my fixes for these problems and the reasons why these issues occur in the first place. I also try out a live recording style for this video, hopefully you like it! Please let me know what you think and see you for whatever I decide to do next, thanks for watching!

Hello everyone and welcome to a new (probably short) series of videos I do involving the source code from Valve for Half-Life 2, and some guides on how to do stuff with this code. In this alternative introductory episode, I go over how to download (and get into a position to compile) the 2013 source code on Linux operating systems using what is known as the docker or container method, including the Steam Deck! I do not, however, go over how to get into a position to debug the code (I actually dont know how to do this right now on Linux!). Please note this only applies to the Source 2013 Singleplayer code and the pre-Team Fortress 2 32-bit version of the Source 2013 Multiplayer code. Please let me know what you think and see you for whatever I decide to do next, thanks for watching!
