A new QuakeC mod by Harlequin (3 this week and counting!). Get it at
ftp.cdrom.com or alt.binaries.games.quake.
Jetpack v1.0
by
Harlequin (dtebben@alumni.caltech.edu)
Operating Systems Supported
---------------------------
Anything that can run Quake.
How It Works
------------
It's a new powerup, a jetpack a la Duke3D. Jetpacks can be placed on
maps as items in their own right, or they can replace biosuits on
existing maps. Jetpacks let you fly (obviously) and have a neat hover
mode so you can rain death on unsuspecting ground-pounders. Intuitive
interface (I don't know what Duke's is like, never played it).
How To Use It
-------------
First you need to compile the mod using QCC. Get a version suitable
for your OS from ftp.cdrom.com or http://www.stomped.com. If you want,
you can also get the latest QuakeC code, version 1.06, from
ftp.idsoftware.com/pub/unsup (or something like that) -- this patch was
created using v1.06 code, but should run just fine under 1.01. 1.06 has
lots of bugfixes and I recommend getting it. After you install QCC, copy
all the files your QuakeC directory (/qcc/v101qc if you're using 1.01)
into a new, empty subdir named "jetpack" off of your Quake directory. Now
unzip jetpack.zip into the jetpack subdirectory, answering "yes" to
any queries about overwriting files. Run QCC in that directory and
it will generate a file called progs.dat. To use the mod, run Quake
with the command-line argument "-game jetpack".
After picking up a jetpack (they'll be in places where biosuits used to
be), you can fly by pressing and holding down jump after you're already in
the air. The simplest way to do this is to double-jump. You'll fly at
approximately running speed in the direction you're facing. Hover mode,
which is always on, means that you cannot sink while thrusting with the
jetpack. This allows you to aim downwards or sideways without leaving
the air, so you can shoot people below you. If you want to drop, let go
of the jump button.
Documentation & Notes
---------------------
By default, jetpacks replace all biosuits. You can assign a random
chance of replacing biosuits with jetpacks in the jetpack.qh file. If
you make a map and want to put jetpacks on it, give them the classname
"item_jetpack". Then you may want to assign the probability of replacing
biosuits to zero, in case you want jetpacks and biosuits on the same map.
While flying, flames shoot out from behind your character. I didn't
want to force players to use any special .mdl files, so I couldn't really
put a jetpack on the player model, but this is almost as good.
Fuel is consumed only when actually firing the jetpack. There's enough
fuel for about 15 seconds of burn, and you are warned a few seconds
before your fuel runs out.
Jetpacks respawn every 60 seconds in deathmatch mode.
The jetpack automatically corrects for sv_gravity, but there is a slight
margin of error. I suspect it may vary based on system performance.
If you die while carrying a jetpack, it and any remaining fuel will be
recovered by whoever picks up your backpack. Picking up additional
jetpacks (or backpacks containing fuel) adds to your fuel store.
Including Jetpack In Another Mod Package
----------------------------------------
This should be very easy. Include jetpack.qh and jetpack.qc in your
progs.src (right below defs.qc), and read the file changes.txt so you
can cut & paste the few minor changes I made to id's code. If you can
code, you can change the biosuit to replace whatever item you want (it
just involves cutting a few lines out of item_artifact_envirosuit and
pasting them into another spawn function).
Known Bugs
----------
None.
