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 demonstrate how you can add a weapon drop system into your mod, where the currently equipped weapon gets thrown away when the ConCommand DropPrimary is triggered. I also talk about some of the issues that exist with this feature and provide some fixes for them. Please let me know what you think and I will 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 episode, I demonstrate how to add Thexa4s PBR shader for the Source engine. Unfortunately, this only seems to be an UnlitGeneric version, plus I cannot tell you how to make textures that make use of this shader, so apologies for this! 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 episode, I introduce an alternative method for shader authoring and show how to get into a position to be able to compile custom shaders for your mod by using a modified compiler by SCell555. Please let me know what you think and see you for whatever I decide to do next, thanks for watching!

Hey everyone and welcome to another session of Matchmade Firefight games in Halo: Reach! I played the Halo: The Master Chief Collection version of 2 player Firefight for this video, with my brother James @eternalknuckles1993 though without his input. Consider the fact that from now on, I dont have a lot of control over what game modes and maps I play on for this series going forward. Please let me know what you think in the comments and Ill see you next time for whatever I decide to do next!

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 showcase how to add radial fog from the 20th Anniversary update to Half-Life 2 into a Source 2013 Singleplayer or Multiplayer mod. For Singleplayer mods, the inclusion of this feature requires the compilation of shaders (which is why this video is part of the Shader Authoring set of videos). I need to give a massive thank you to @WadDeIz_Real for making the guide that I followed in the video! Keep in mind that you need to use the Perl/DirectX SDK method to compile shaders if you choose to add this, or get this video to 50 likes, then I will add the code to my GitHub! Please let me know what you think and see you for whatever I decide to do next, thanks for watching!
