![Valve Source Code 2013 Tutorial (Episode 20.5): Fixing Issues With The Hopwire [Black Hole] Grenade @TheMaster974](https://i.ytimg.com/vi/K5gSCSOMuh0/maxresdefault.jpg)
Uploaded November 2025 | Updated September 2026, 22 hours ago
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 Hopwire tutorial I did a while back by resolving a game crash that happens in Source 2013 Multiplayer mods, possibly as a result of the 64-bit update, as well as fixing a bug that occurs when the black hole grenade tries to consume Gunships and Dropships. I also go over how to make the screen flash occur if the player has a line of sight to the Hopwire when it detonates and how to make the Hopwire usable again if all ammo is exhausted. Please let me know what you think and see you for whatever I decide to do next, thanks for watching!
