Dies beschreibt die Erstellung des Greifhakens, wie er in der Obsidian Conflict Modifikation zu finden ist. Der code wurde von Hyperjag3 geschrieben.
Wenn jemand dies fortführen und eine Dokumentation über die Funktionsweise schreiben will, wäre es nett. Ich habe leider nicht die Zeit, das zu tun.
Die Waffe wurde für einen Multiplayer entwurfen, sollte aber gut in einem Singleplayer funktionieren, wenn Referenzen zu hl2mp entfernt werden. Es verwendet das Armbrust-Modell.
Hinweis:Wenn du den Quellcode in deiner Modifikation einbinden willst, dann dem Obsidian Conflict Team entsprechende Credits in der Readme-Datei deiner Modifikation. Danke. :)weapon_grapple.h
