The author assumes that anyone reading this FAQ has
already read the manual that came with Mapedit. Sometimes
I will tell you the keys also, but that is just to try
and make it easy for the reader. Sometimes I don't
say the key. If you read the manual I feel you will benefit greatly from this FAQ, and in your own MAP making. At this time it is unclear if there will be a user question section,like planned, at the end of this FAQ. It is possible, but we will have to be patient. I can be reached by E-MAIL at JEChap@msn.com. Please do not send me
This FAQ was originally started based on the demand for a FAQ that
would help people create MAPs for Blood using MAPEDIT. I saw a lot of
questions. A lot I could answer so I decided to start a FAQ. I will show
you how to do many things, from creating a sector, to blowing up walls and
II. What is MAPEDIT?
MAPEDIT is a program used to make Blood MAPs. Originally Build,
MAPEDIT now supports new features, for the new BUILD engine. (BUILD was the
engine used in Duke Nukem 3D, and being used in Shadow Warrior). You use
MAPEDIT by drawing the sectors in a 2D area. Then you can switch to a 3D
edit are using the keypad 'ENTER' and change the height, shading, textures,
palettes, and a bunch more. Also in 2D mode you will edit, what I like to
call the hard code section, its what make the levels do what they do. And
I like to call what you do in 3D edit mode cosmetic code. Its more for looks
then for how everything works. However they both contribute equally much to
making an exciting MAP for Blood.
III. Simple Editing to get your feet wet
To draw a sector in MAPEDIT place the mouse cursor where you want to
start and press 'SPACE' continue the process until you close the sector.
The lines will be white. This means that they are solid walls, and you
can not pass through them, or see the other side of them. Make sure that
the white arrow is inside the sector that you just created, if it is not,
then move the mouse cursor inside the sector and right click with the mouse.
then press the keypad 'ENTER' to enter 3D mode. In 3D edit mode use
PgUp / PgDn to change the height of the floor and ceiling or the sector that
the mouse cursor is pointed on, or selected. Using '['/']' will change the
slope of the Floor or ceiling (not walls). Use 'V' to select a texture for
a surface (i.e. Wall, Floor, Ceiling). First it will show all the textures
currently used in the MAP; however, it will only show the textures for that
kind of texture; for example, if you are editing the floor texture it will
only show the textures that you have used on the floor. Press 'V' again and
you will be able to see all the textures. (Not all the Textures are meant
for Walls, they are also for Sprites and other things (We will talk about
that later)). You can add more sectors inside of the sector you created by
following the same process as before but inside the sector. The lines
will be white and you will have created a column-esque structure in your
MAP. To make the sector so that you can walk through it or change the
height. have the mouse cursor over one of the walls (in 2D mode) and press
ALT-S. The walls of that sector will now become red. You can go into 3D
edit mode and you will see that it looks like the sector is gone. Its there
it just has all the same attributes as the sector that it came from. You
can edit the height and textures and whatever of it. Lift the floor to make
a counter. You can create a lot of things with this simple feature, be
creative. To view the properties of a sector press F5 and to edit them
hit ALT-F5. Remember to have the mouse cursor inside that sector first.
This feature will become important later on in this FAQ.
IV. Adding Sprites
You can add sprites from either 2D or 3D edit mode. To add a sprite
from 2D edit mode move the mouse cursor to the spot that you want to insert
the sprite, then press s. you will see a little blue circle with a stem.
The stem is the direction that the sprite is pointing in. This is a face
sprite, that's all that all that you can create from the 2D edit mode.
Sometimes when you place a sprite in 2D mode the height of it is below or
above the ceiling. For this reason I like to place the sprite in 3D mode
first and then go back to 2D mode to fine tune the position or whatever,
unless its a sound sprite, then it doesn't really matter. In 3D mode you can
place two different kind of sprites. To make a face sprite put the mouse
cursor on the floor and press 'S'. You will see all currently used sprite
textures, press 'V' and you will see all art tiles. To make a wall sprite
place the cursor on the wall, towards the top, and press 'S', then the rest
of the process is the same as the face sprites. To switch between the kind
of sprite after it has been created use 'R'. There are three possible kinds
of sprites in Blood, Wall (Flat), face, and floor sprites. face sprites
always face the player. Wall sprites remain facing the same direction, and
floor sprites remain facing the same direction but are looking up(or down).
To create Enemies or Ammo the best way is in 3D mode instead of using 'S',
use ALT-'S', A pop-up menu will appear, follow the menu to get what you want.
This way you don't have to do any of the editing in 2D to make sure that they
serve the appropriate purpose. However, in case you are wondering how you
would edit them in 2D, here is what you do. Create the sprite. Then in 2D
edit mode press ALT-F6 on the sprite. A box will come up where you can edit
the properties of the sprite. The first box that is selected is where you
would have to change for enemies, ammo, or keys to take effect. Locate the
appropriate Type of what you want and hit 'ENTER' to save. Use 'ESC'
to cancel while you are editing. you can view the properties of any sprite
by just using F6. This box allows many features in MAPEDIT. More on those
V. Making Z-Motion Sectors
Z-Motion Sectors can be used to create some really cool effects in
Blood. They are used for lots of things, from destruction to
changing the height of water. They are used for doors and elevators to.
To make a Z-Motion Sector you must edit the properties of the sector by
using ALT-F5. Change the Type to Z-Motion. To adjust the positions for the
Z-Motion Sector go to 3D edit mode. Select where you would like the Sector
to be in the OFF position. when you find it press ALT-F3, the position is
now changed. Pressing F3 will show you the OFF position. ALT-F4 and F4 work
the same way for the ON position. Selecting a Busy Time for the OFF->ON
(going from OFF position to ON, ON->OFF is just the opposite) or ON->OFF
will tell how long it takes to go from the one position to the other. If you
select a waittime this is how long the sector will wait before returning to
the other position. Very useful for doors that you want to close after they
have been opened by the player. It is helpful when editing to leave the
sector in the ON position so you can see by it, but be sure that the state is
OFF. Usually you should press 'O' on the sides of the Z-Motion sector so
that the textures stay in the same place and don't change with as the sector
changes its Z-Position.
To make a Z-Motion Door create the Z-Motion sector like explained
above. Select the Textures as you please, although its not necessary, it
is essential to have the Textures be what you want in the MAP. Select the
TRIGGER ON: Box for WALLPUSH. This way whenever the player pushes (uses
the action key, on a wall it will activate the sector. If its ON, then it
will go OFF. If OFF then ON. Or if Interruptible is set then in between in
one direction to the other).
To make an elevator create the Z-Motion sector like above. Select
the Textures that you want. This time Make sure that your ON and OFF
positions are always open and have the same amount of space in between them.
That way they will look like an elevator. To make an Elevator trigger when
the player steps in the elevator select the TRIGGER ON: box for ENTER. This
To make the user press the action key to activate it select PUSH. WALLPUSH
to make the player press the action key on the wall. You can select multiple
trigger options. We will discuss how to make it trigger by other Triggers
in the Trigger Section.
Z-Motion Sectors are used to create many of the cool special effects
in the Blood Levels. If you want a Wall to fall then you use Z-Motion
Sectors. If you want to blow a hole in a wall then you use Z-Motion Sectors.
VI. Making Sliding Sectors
To make a sliding sector make the sector that you want to slide.
Make the sector. Change its type to Slide. A new sprite type gizmo
appears on the screen. Place the sector in the on position and put the arrow
part of the sprite on the sector, and the stub end of the gizmo where you
want the part that you have the gizmo pointing to go. The gizmo doesn't
really have to be pointing to anything on the sector it just makes it easier
for me, so I recommend that way. It makes it easier to see for me. Make sure
that the State is OFF. That way when the level is started the sector will be
where the stub part of the gizmo is. Again the busytime and waittime do the
same thing as for the Z-Motion Sectors. To make the texture stay relative to
the sector and not stay in the same spot hit 'R' on the surface of the
sector. They can also be triggered all the same ways as Z-Motion Sectors.
!!!This is not how you make Sliding Doors, due to the fact that you can't
have a sector slide between sectors. This is for the Same reason as for
why the Rotating Sectors can't go between sectors!!!
-Sliding Doors are explained in Chapter XVI: Sliding Marked
VII. Making Rotating Sectors
To make a Rotating Sector first create the sector in the on state.
Then make the type Rotating, keeping the state in OFF. A rotating
sprite will be created. This sprite tells the sector how much to rotate. It
does not point in the direction that the sector will rotate. Instead it
tells how much to rotate. When it points to the right it is at 0. When the
angle is negative the sector will rotate counter-clockwise. If the angle is
positive then the sector will rotate clockwise. The angle number will tell
how far. Use it from the 0 to whatever. And just rotate everything in your
mind so that the 0 angle is the way the door is, and then the angle pointing
is at the place where the door will be. (By the way: The number used for the
sprites angle is from the ON Position to the OFF. To figure out the OFF
position the Build engine just goes backwards from the ON position to the OFF
based on how far it would rotate to get to that ON position. Sometimes this
can make it seem like the positive number is for counter-clockwise.)
Make sure never to have the sector rotate into another sector. The
Build Engine renders a whole sector at a time (The one closest to you, and
then continuously further away), and has a mask file which won't let the
engine write to the screen in any place that had been drawn to before.
That way you get Hidden Surface Removal. If the sector goes into another
sector that is closer to you then you will only see the part of the door
in the other sector. Very Ugly!!!
Again this kind of sector can be activated just like Z-Motion or
VIII. Making Water
There is two basic kinds of water. The kind that you stay on top and
you dip down and here the sound effects, and the kind that you can go under.
First I will explain the first kind of water.
To make water that you stay above and dip down in, make a sector like
normal and have the floor texture be one of the water textures. Then to
define how deep you dip down change the depth field. It ranges from 0-7.
This is called the GOO depth field. The engine has no information about
anything under the water. There is nothing there. It just makes sounds
so that it sounds like water (when jumping in it), and it adjusts the height.
To make the kind of water that you can go under, make two sectors.
The first sector is for above water and the other is for below water. Make
the floor of the above sector a water texture, and make the ceiling of the
below sector have the same texture as the floor on the above sector. Create
two sprites, one in each sector. Change the type of the sprites so
that the above sector sprite is Upper Water. and the type of the
below sector sprite is Lower Water. !!!Very Important: Make sure that the
sector for above and below water is identical in 2D mode. That's the shape
and size. The heights and certain properties can be different but you have
be able to come out of the water in every place you can come in. That's just
common sense!!!. In 3D mode you will see that they are arrows pointing up
and down. Down for above water and up for below water. Put these sprites on
the ceiling for below water, and on the floor for above water. Make sure
that these sprites are in the exact same location in both sprites so that
they are aligned correctly. Edit data field one on the sprites. Put the same
number in them. This tells the engine which sector to look to for above or
below the sector. Edit the sector property for below the water. Check the
box next to underwater so that it will be blue under water and you will be
able to float, and suffocate.
IX. True Room over Room Sectors
Room over Room sectors are almost identical to water sectors.
Instead of selecting a water texture for the ceiling and floor of the sectors
put texture #504 on them. Make the type of the two created sprites
Upper Link and Lower Link. Put the number in data field one again. Do not
make it underwater since its not. That's all there is to it.
To make a sprite or wall translucent press 'T' on it. To make a wall
Translucent it must be a masking wall. Masking walls are between the floor
and ceiling of a sector and are visible blocking objects with sectors on both
sides of it. You can make any sprite Translucent. To make a window you can
take either method. I prefer sprite just to make it gibable, or breakable in
this case. create a wall sprite, put it where you want the window, select
the texture for the window, and then press 'T' to select the translucency
level. There are only three levels, all none, or 50/50.
To make translucent water you actually create two Room over Room
Sectors instead of two water sectors. However the two sprites are still
labeled upper water and lower water. However you use texture #504 instead
of the Water texture. Instead you create sprites for the water. Create
the sprites to fill the space on the floor of the above water sector. Make
the sector a floor sprite, and make it on the floor. Use Ctrl-PgDn to put
it exactly on the floor. Then make the sprites translucent using 'T'. Its
kind of like faking translucent water by making two room over room sectors
with a water translucency sprite to make it look like water. You only need
the sprite on the above water sector because you will see it from below when
it goes above the ceiling.
Mirrors are very easy to make. Just change the texture of what you
want the mirror to be (must be a wall), to texture #504. That's all there
is to it.
Triggers are very useful, whether they are from trigger switches or
event triggers. First, to make a trigger switch create whatever you want
to be triggered. Then create a sprite for the switch. I recommend using
ALT-S that way the type will already be set to Toggle Switch.
Give the sprite an unused Transmit Channel (Must be >=100), and give the
sector (or whatever) that you want to be toggled the same Receive channel.
(By the Way: Transmit and Receive Channels are labeled as Tx and Rx in
MAPEDIT.) Change the CMD of the switch to Toggle. Make sure its checked to
send at both ON and OFF. Have it trigger on Push. That means whenever the
player uses the action key on it will be triggered. (Note: sometimes you
don't want a switch that toggles all the time. Maybe you might want a 1-way
switch. Just change the type of it to 1-way switch. Plus there are
Different CMDs to use. They will partially listed below).
To make something trigger on an event, such as Entering a room.
Create the sector that is going to be the room. Give it an Unused Transmit
Channel. Make it transmit going ON and OFF. Have it be triggered on ENTER.
Make the CMD Toggle. Make whatever you want to be triggered and give it
the Receive channel that same as the Transmit on the other Sector.
Then it will be activated whenever someone steps into that room.
(Note: That example is for entering a room only, everything is similar to
that so that should be enough to get you experimenting and easily figuring
You also use Triggers to tell when the player has found a secret.
To do this Set the CMD to #64 which is 0. Set the Transmit Channel 2. That
is the reserved channel for secrets. Check off 1-shot to ensure that the
player only gets credit for the secret once. Select send on OFF->ON. You
can anything activate it. To have it say "found a secret" when the player
enters the room, select Trigger on ENTER. That's all.
CMDs: ON: Turn the Object (Whatever you have it set to) to ON
OFF: Turn the Object to OFF
Toggle: go from OFF->ON or ON->OFF
Link: to link Objects together
Lock: To lock the Object
Unlock: Unlock the Object
Toggle Lock: go from Locked->Unlocked or Unlocked->Locked.
Also on what's being triggered you can change things like how many
times it can be triggered and such. For example, if you want something
to only be triggered once check off 1-shot. If you want it to be able to
change its state while in the middle of transition check off interruptible
XIII. Light Switches
To create a light switch first create the sector or sectors to be
shaded by the switch in the OFF position. Create a switch and give it an
unused Transmit Channel, and set the CMD to Toggle. In the sector or sectors
that will be effected create the corresponding Receive Channel. Go into the
FX section under the Sector properties. In the lighting section check off
ceiling, walls, and floor to shade the whole sector. Set the amplitude to
the amount that you want the shade to change. + is darker, and - is brighter.
You can use anything to trigger lighting effects, not just switches.
XIV. Making Walls Blow up with holes
To make holes in walls make the sectors where the hole will be. Make
these sectors Z-Motion. Put the sectors in the position that you want for
when the hole is open. Save each sector of the hole in the ON position.
Use ALT-F4 incase you forgot. Then close the hole and save all the sectors
in the OFF position. Put all the sectors state in the OFF. Put a wall
sprite on the wall where you want the hole to be (doesn't have to be but
would be kind of stupid for it not to be) using ALT-S in 3D mode, and select
misc-Wall Crack. In 2D give the Wall Crack sprite an unused Transmit Channel
and give all the sectors for the hole the corresponding Receive Channel.
On the sprite make the CMD: ON. Have it send when going ON. For the sectors
check off the 1-shot.
To add explosions when the hole is created, make sprites, and change
the types to hidden explosions. Give them the same Receive channel
as the Sectors. Use the waittime to decide when the hidden explosion will
go off. It is better to have the explosion last with multiple blows then to
have one great big one at the same time. Or at least that is my visual
preference, and I guess Monoliths too, as that is the way all the levels that
have exploding walls do it.
You can make a wall blow up by making anything transmit CMD: ON, to
XV. Z-Motion Sprites
Z-Motion Sprites are loosely similar to Z-Motion Sectors. They both
use ALT-F3 and ALT-F4 to change their heights. But they react use them
very differently. First Create the Sector that the sprite will be in, then
create the sprite. Change the Type of the sector to Z-Motion Sprite.
Set the Sprite in the OFF position. Save the position using ALT-F3. Then
move the floor to the amount that you want the sprite to move, and press
ALT-F4. After that put the floor back to where you want it and then mark
the sprites that you want to move. Use 'K' to mark the sprites.
(NOTE: This was the hardest thing to figure out. With the help of Philip
Buchan, we figured it out. I knew about the marking, and the sector being
Z-Motion Sprite, which is the easier part. And he somehow figured out how
to change the heights using the floor. Thanks Phil!!!)
XVI. Sliding Marked
Sliding Marked is used for Sliding either walls or sprites. This
works very much similar to Sliding Sectors. First Create the sector that
the sprite or wall will slide through. If it is a sprite place the sprite
inside the sector. Make the Sector type Slide Marked. A Sprite will appear
that is exactly the same as for Sliding Sectors except that it is for
Sliding Marked. Again it can be anywhere but helps to be on the thing that
you want to slide. to mark something for slide use the 'K' key. The sprite
or wall will turn Blue. If you press 'K' again, it will turn Green. Blue
means to go in the direction that the arrow sprite indicates, and Green
means the opposite. So if you wanted to make a gate, one side would be green
and the other would be Blue. That way they would join and separate together.
Use the busytime and waittime of the sector just like you would for anything
else. To toggle this from a switch give the sector the Receive channel.
If you want the player to push on the sprite to have it slide, Give the
sprite the Transmit Channel that corresponds to the Sectors Receive Channel,
mark it to send on PUSH, going ON, going OFF, and change the CMD: to Toggle.
To do this with walls (i.e. to make sliding Doors) you must make the
sector that slides marked in a special way. The following Diagram tries
to show you. The lines are white.Red is two lines together. The numbers
indicate in what order to make the lines. This is for a single door.
If you can notice from
this diagram after step 1 you go back to the end of
