This tutorial will teach you how to customize
terrorist equipment and orchestrate terrorist behavior.
This tutorial assumes
that you are already familiar with UnrealED and know how to
load a simple custom map into Raven Shield. If this is not the
case, take a look at my earlier tutorial, Building
Your First Raven Shield Map, and then come back to this
one. I'm not going to spend much time in this tutorial dealing
with textures, lighting, or insertion points. I'll assume you
know what you're doing and can improvise these as you go
along.
To start out, let's build a
simple 4 room map. Set your grid to 128 units. Select any wall
texture you like, and then carve out a cube sized
Height=256,Width=768,Breadth=768. Now drag the builder brush
and carve out a second room exactly 128 units to the North and
128 units to the West of the first room. Repeat this procedure
two more times, so that you have four rooms, spaced out in a
diagonal line. Now let's connect the rooms, but we don't want
a direct line of sight between the rooms so we'll create right
angle hallways. Carve out a hallway to the North of the very
first room, sized Height=256,Width=640,Breadth=256. Carve
identical hallways North of the 2nd and 3rd rooms. Now carve
out a hallway to the East of the 2nd room, sized
Height=256,Width=256,Breadth=384 (this should connect the 1st
room to the 2nd). Carve identical hallways East of the 3rd and
4th rooms. Now, all four rooms are connected, and we'll be
able to design one encounter (to use a role-playing term) at a
time. Your map should look like this:
Add an
insertion zone in the first room (click
here if you need instructions for this). Open the Actor
Classes browser, expand "Info" and select "ZoneInfo". Right
click anywhere in the first room, and choose "Add ZoneInfo
here". Reposition the icon if necessary, making sure it isn't
embedded in any floors or walls. Open the properties for the
ZoneInfo icon, expand "ZoneLight", and set AmbientBrightness
to "128" and AmbientHue to "64". (This is a lazy way to light
a level, but lazy is good for testing and tutorials.)
Path Nodes
We need to add path nodes so
that terrorists and operatives can find their way around the
map. The insertion point itself serves as one path node. The
rule for path nodes is very simple: each path node must be
visible from at least one other path node, and they should not
be over 1000 units apart. Right click in the hallway corner
between the 1st and 2nd rooms and choose "Add Path Node Here".
An apple icon will appear. The icon should sit about 40 units
above the floor (if you add it from the 3d perspective view,
it will place itself at the proper height). Add a path node in
each hallway corner and in the direct center of each room
(except room 1, which has the insertion zone). Now, rebuild
your map, using the "Rebuild Paths" button, or the "Build All"
button (assuming you have "Build Paths" turned on in the build
settings). If any of your path nodes is isolated from the
others, an error message will appear. If this happens, select
the Actor name, click the "Go to Actor" button, and then
reposition that path node, making sure that it is within
visible range of another path node.
You do not need to
go overboard with placing path nodes. The AI is pretty smart,
it just needs help finding it's way around corners and across
long distances. But keep in mind that the AI does think for
itself, so it will wander off the beaten path sometimes. If
you've got a broom closet that you think will never be used...
it's a still good idea to drop a path node outside it just in
case a terrorist flees into the closet in a moment of
cowardice, so he can later find his way back out. Without path
nodes, if you leave your team a room or two behind and then
call them to rejoin you, they will object because they don't
know how to get to you. And without path nodes, you will need
to place waypoints every few feet in the planning stage;
whereas if you have good path nodes on your map, you can place
a waypoint on the far side of the map and the engine will auto
calculate the best path to get there.
Placing
Tangos and Hostages
Let's place some terrorists.
Open the actor class browser, expand "R6DeploymentZone", and
select "R6DZonePoint". Right click somewhere in the 2nd room
and choose "Add R6DZonePoint Here". Place two R6DZonePoints
anywhere in the 3rd room, and place two in the 4th room as
well. Open the properties for the very last R6DZonePoint you
added (in the 4th room). We're going to make this guy a
hostage. Expand "R6DZoneHostage". Set m_iMaxHostage to "1",
and m_iMinHostage to "1". Expand "R6DZoneTerrorist". Set
m_iMaxTerrorist to "0", and m_iMinTErrorist to "0". We haven't
setup the proper hostage rescue mission objectives (I'll cover
this in a future tutorial), so we won't be able to
extract/rescue this guy, but the terrorists will be able to
interact with him (in other words menace and kill him).
Let's throw in one random terrorist for tango hunt and
lone wolf missions. (Note that by default, random tangos will
appear in "mission" game types, however fixed tangos will not
appear in tango hunts. Random tangos can be removed from fixed
missions using the R6Availability settings.) Open the actor
class browser, expand "R6DeploymentZone", and select
"R6DZoneRandomPoints". Right click near the center of the
hostage room and choose "Add R6DZoneRandomPoints Here". Two
new icons will appear. The larger icon represents the random
tango who will spawn, and the smaller icon represent a
RandomPointNode, one possible position where he could spawn.
Open the properties for the R6DZoneRandomPoints (the larger
icon) and expand "R6DZone". Select m_aNode and then click the
"New" button. Reselect m_aNode and click the "New" button two
more times to create four random nodes in all. Drag each
random node to a separate corner of the room. Now, each tango
hunt game, a single terrorist will spawn in one random corner
of this room.
Several things to note
about random terrorist spawns: First, you should only ever
have one 'R6DZoneRandomPoints' actor in your entire map. All
RandomPointNodes should be created from this single
RandomPoint. Second, make sure that you create each
RandomPointNode using the steps described above. If you try to
duplicate a 'R6DZoneRandomPointNode' using [Ctrl]+w, it won't
work properly. Finally, please note that if the player
launching your custom mission selects a number of terrorists
higher than the total number of RandomPointNodes available on
your map, the game will attempt to fill every Node.
Kits/Templates
At this point,
rebuild and run through the map once in-game if you'd like
(choose "Practice Mission"). You'll see that all five
terrorists are identical twins, they all carry silenced MP5s,
and they all have Spanish accents. Let's adjust those accents
first. From the "View" menu in the editor, select "Level
Properties". Expand "R6Sound" and set m_eTerroristVoices to
"TN_German1". Close the level properties window.
Now
open the properties for the lone tango in the 2nd room. Expand
"R6ZoneTerrorist". At the bottom, expand "m_Template" and then
expand "[0]". These settings show us that by default, there is
a 100% chance to load a template named "Normal". Leave the
properties window for a moment, open the "View" menu in the
editor, and select "Show Template Browser". Scroll down in the
left column of Terrorist Templates, and double click on
"Normal". As we can see, the default terrorist has a 100%
chance to wear the R6TParamilitary01 skin, and a 100% chance
to carry a silencedSubMP5SD5. We could modify this template if
we wanted to, but I think it would be better if we created our
own template instead. Change the Template name from "Normal"
to "Abnormal". Set Assault to "100". Under Pawn chance, select
"100%, R6TParamilitary01" and click the "Remove" button. Now,
in the Pawn chance dropdown box, select "R6TSkinhead1" and
change "100" to "50". Click the "Add" button. Next, select
"R6TTropical1" from the dropdown box, keep the percentage set
to "50", and click the "Add" button again. In the "Weapon"
section, select "100%, SilencedSubMP5SD5" and click the
"Remove" button. Now, in the Weapon dropdown box, select
"NormalPistolP228", keep the percentage set to "100", and
Click the "Add" button. Finally, set Flashlight to "80". Click
the "Create" button at the bottom. This will create a new
terrorist template option named "Abnormal" without modifying
the "Normal" kit. Back in the properties window, with
"m_Template | [0]" still expanded, change m_szName to
"Abnormal". Now our terrorist friend will have a 50% chance of
being a skinhead and 50% chance of being a Miami Vice hood. He
will usually carry a flashlight, and will only be armed with a
pistol. He'll also be a pretty good shot. Note that templates
are stored in the "\RavenShield\template\" folder (".tpt" for
tango kits and ".tph" for hostage kits). If you create custom
templates, it is very important that you distribute the new
".tpt" and ".tph" files along with your map.
Let's
change the kits of the other three terrorists as well. Open
the properties for each one, expand "R6ZoneTerrorist",
"m_Template", and "[0]", and then assign an existing template
from the Template Browser ("Alpines-3", "Garage-5", etc., but
make sure the template actually exists). Click here if you'd like to see a labeled
picture of every possible terrorist kit (thanks to Trancer
for putting this together). On the last guy, change m_iChance
to "30" and keep m_szName set to "Normal". Then, expand "[1]"
and set m_iChance to "70" and m_szName t0 "Abnormal". This
tango will now have a 30% chance to appear as the familiar
clone with the MP5SD and a 70% chance to be born with our
custom pistol and flashlight kit. Of course, this also means
that there is a 35% chance he'll appear as a skinhead, and a
35% chance he'll appear as a beach bum. So between the
percentages you specify in the editor, and those you specify
in the template file, you can easily add a large random
element to exactly who the Rainbow team will be fighting each
time.
You should know how to assign kits/templates
now. Go ahead and assign a new template to the hostage in the
4th room (make sure it's a hostage kit and not a tango kit,
for obvious reasons).
Patrols
Let's add another tango to
the 2nd room and give this one a patrol route. Open the actor
class browser, expand "R6DeploymentZone", and select
"R6DZonePath". Right click in any corner of the 2nd room and
choose "Add R6DZonePath Here". Three icons will appear, one
large gingerbread man symbolizing the tango, and two smaller
icons identifying nodes in his patrol path. The position of
the larger icon really doesn't matter. Let's reposition the
smaller icons so that each is in a different corner of the
room. Select the larger icon, open the R6DZonePath properties,
and expand "R6DZone". Select m_aNode and then click the "New"
button. A third node in this path, will be created on the map.
Drag this node to a third corner of the room and open it's
properties. Expand "R6DZone". Set m_AnimChance to "100" and
set m_AnimToPlay to "RelaxWaitLookFar". This terrorist will
pace slowly between the three nodes. When he reaches the
third, he will peer into the distance and then retrace his
steps, continuing to patrol until the enemy is spotted.
Reactions
Move to the 3rd room, open up
the properties for one of the tangos, and expand
"R6DZoneTerrorist". Change m_eDefCon to "DEFCON_0" (highest
alert status--kudos to the developer who named this setting)
and and m_eEngageReaction to "EREACT_AimedFire". Switch to the
other tango in that room and set m_eDefCon to "DEFCON_5" and
and m_eEngageReaction to "EREACT_RunAway". Rebuild and save
the map. Load the map in-game and immediately type
"PlayerInvisible" into the console (open and close the console
with the "~" key). Now, hold your fire, and walk around the
map to observe the behavior of the terrorists. Notice that the
tango in DefCon_5 mode is pretty laid back: yawning, picking
gum off his shoe, and looking pretty bored with his
assignment. Meanwhile, the tango in DefCon_0 mode is aiming at
the doorway with his eye to the gun sights. You can switch out
of invisible mode if you'd like, but at this point the bad
guys' reactions upon spotting you will be pretty standard.
Action
Spots
Return to the editor. Open the actor class
browser and select "R6ActionSpot". Right click near the center
of the 2nd room and choose "Add R6ActionSpot Here". A question
mark icon will appear. (For some inexplicable reason, I
couldn't add an action spot on this map by right clicking; it
worked on other maps, so I ended up copying the object from
another map... I only mention it in case anyone encounters the
same problem.) Open the properties for the R6ActionSpot and
expand "R6ActionSpot". Set m_blInvestigate to "True", m_eCover
to "STAN_Crouching", and m_eFire to "STAN_Crouching". Rotate
the R6ActionSpot icon so that the red arrow points toward the
1st room. Note, that unless you tell the terrorists to stay
put, they will make a beeline for your position (or where they
think they heard you) regardless of any action spots. So open
the properties for our original "Abnormal" fellow in the 1st
room, expand "R6DZoneTerrorist" and set m_bAllowLeave to
"False". Now, if that tango hears trouble from the 1st room,
he'll take position on that action spot. However, once he
spots you, his survival instinct will take over and his
behavior may change...
Reinforcements
That 2nd room will be pretty easy to clear, so let's
allow the tangos to call in reinforcements. Select both tangos
in the 3rd room, open their properties, and expand
"R6DZoneTerrorist" again. Set m_iGroupID to "1". This of
course, assigns these two to an AI group named "1". Now,
select the patrolling terrorist in the first room. We're going
to make him a scout. Open his properties, and expand
"R6DZoneTerrorist". Change m_eEngageReaction to
"EREACT_Surrender". Select m_iGroupIDsToCall and then click
the "Add" button. Set [0] to "1", telling the scout to call in
reinforcements at the first sign of trouble.
Guarding Hostages
Finally, move to the
4th room and open up properties for the fixed (not the random)
terrorist in that room. Set m_bAllowLeave to "False",
m_eDefCon to "DEFCON_0", and m_eEngageReaction to
"EREACT_AimedFire". Change m_HostageShootChance to "100".
Select m_HostagZoneToCheck and click the "Add" button. Next,
click the "Pick" button. Left click the eyedropper on the
hostage icon (the pink gingerbread man) to identify the
hostage that we want this terrorist to shoot.
Conclusion
Play the map again, and
don't go invisible this time. As soon as the scout spots you,
he will surrender, but not before first calling for his
associates, who will immediately come running to kill you.
(Mr. DefCon_5 will humorously come to his friend's aid but
then run away as soon as he sees you.) Notice that the
EngageReactions and GroupIDsToCall do not kick in until the
terrorist has spotted you with his own eyes.
Once
you've cleared the outer defenses, move into position outside
the hostage room. Be careful, because as soon as the terrorist
inside sees you he will focus all of his efforts on
immediately killing the poor hostage. (Luckily, if he spawns
using the "abnormal" template we created, he will only have a
pistol and it may take him a few shots.)
I hope you found this tutorial helpful. If
there's anything I've gotten wrong, please let me know and
I'll correct the information. Email me if you have any
questions or mapping issues you'd like to discuss. -Beckett
