This is how we made the grappling hook found in the Obsidian Conflict Mod. The code was written by Hyperjag3 and Skidz. You can find an improved version on YouTube created by user MaestroFenix, and you can grab the code from GitHub to try it out in your own mod.
If somebody would like to take this apart and write some documentation on how it works, that would be nice. I just don't have the time to do it unfortunately.
The weapon is designed for multiplayer, but should work fine in a single player mod once you swap out references to hl2mp. It uses the crossbow model.
NOTE: If you include this code in your mod in some way, please give the Obsidian Conflict team credits in your mod's readme file. Thank you :)
This code was uploaded on 2009, and outside of leaving the part of making the client version of the code, it contains some bugs like moving on all the directions the player or not pulling always. However, a new version has been made:
- Replaced the spring method for vectors. It gives higher control to the player instead of just flying on all the directions.
- Added a rappel mode, so now players can descend/brake their falling speed safely.
- The grapple hook can fire now the "hook" faster (this could be done just with a viewmodel that has a fast reload, but it has been fixed at the code).
- Replaced the bolt and rope for a beam, to make it more pretty.
- The "hook" now can be seen right both in first and thirdperson. Before, due the way it was made, it looked fine at thirdperson, but it was moved at the viewmodel.
- Uses the Gravity Gun as model.
Apart of giving credits to the Obsidian Conflict Team, you also have to give credits to Maestro Fénix, who is the creator of this improved version.
You can see a video demostration of it here.
