3 Wazat's Nexuiz Grappling Hook

8 Installation instructions:
9 --------------------------
11 1. Place hook.c in your gamec source directory with the other source files.
13 2. Add this line to the bottom of progs.src:
17 3. Open defs.h and add these lines to the very bottom:
19 // Wazat's grappling hook
21 void GrapplingHookFrame();
22 void RemoveGrapplingHook(entity pl);
23 void SetGrappleHookBindings();
25 float GRAPHOOK_FIRE = 20;
26 float GRAPHOOK_RELEASE = 21;
27 // (note: you can change the hook impulse #'s to whatever you please)
29 4. Open client.c and add this to the top of PutClientInServer():
31 RemoveGrapplingHook(self); // Wazat's Grappling Hook
33 5. Find ClientConnect() (in client.c) and add these lines to the bottom:
35 // Wazat's grappling hook
36 SetGrappleHookBindings();
38 6. Still in client.c, find PlayerPreThink and add this line just above the call to W_WeaponFrame:
42 7. Build and test the mod. You'll want to bind a key to "+hook" like this:
45 And you should be done!
