- Wazat's Xonotic Grappling Hook
-
- Contact: Wazat1@gmail.com
-
-
-Installation instructions:
---------------------------
-
-1. Place hook.c in your gamec source directory with the other source files.
-
-2. Add this line to the bottom of progs.src:
-
-gamec/hook.c
-
-3. Open defs.h and add these lines to the very bottom:
-
-// Wazat's grappling hook
-.entity hook;
-void GrapplingHookFrame();
-void RemoveGrapplingHook(entity pl);
-void SetGrappleHookBindings();
-// hook impulses
-const float GRAPHOOK_FIRE = 20;
-const float GRAPHOOK_RELEASE = 21;
-// (note: you can change the hook impulse #'s to whatever you please)
-
-4. Open client.c and add this to the top of PutClientInServer():
-
- RemoveGrapplingHook(this); // Wazat's Grappling Hook
-
-5. Find ClientConnect() (in client.c) and add these lines to the bottom:
-
- // Wazat's grappling hook
- SetGrappleHookBindings();
-
-6. Still in client.c, find PlayerPreThink and add this line just above the call to W_WeaponFrame:
-
- GrapplingHookFrame();
-
-7. Build and test the mod. You'll want to bind a key to "+hook" like this:
-bind ctrl "+hook"
-
-And you should be done!
