<h2 align="left">The Basics<a name="THE_BASICS"></a></h2>
<p align="left">Once you start editing in viDOOM you should be
greeted by a screen similar to the following (no prizes for
guessing the map number):</p>
<p align="left"><img src="ed_sect.gif" width="640" height="480"></p>
<p>At the top of the screen is a title bar which shows the
following information, going from left to right:</p>
<ul>
<li>The edit mode. This is either 'Sector', 'Linedef',
'Thing' or 'Vertex'.</li>
<li>The position of the mouse pointer in the map.</li>
<li>The current scale</li>
<li>Whether movements are locked to the current grid scale.</li>
<li>The grid scale. The first number indicate the grid scale
that objects are snapped to. The second number indicates
how big the graphical grid displayed is (the blue lines
in the picture above). This second number changes
automatically as the display is zoomed in and out.</li>
<li>Below this is a line where specific edit modes can show
extra information.</li>
</ul>
<p>Note that the information bar at the top of the screen will
also indicate what format the level you're editing is in. If the
background to the title bar is blue, this map is in the original
DOOM format. If the background is red then the map is in the
extended HEXEN format.</p>
<p>The main central part of the screen is made up the map being
edited.</p>
<p>Spread around the bottom of the screen are information boxes
that display details of the object the mouse pointer is currently
over. The size and information in these boxes changes with the
edit mode.</p>
<hr>
<h2>Basic Mouse Operation<a name="BASIC_MOUSE"></a></h2>
<p>The mouse acts in exactly the same way, independent of the
mode. </p>
<p>Moving the mouse over an object will change it's colour,
indicating it can be selected. Simply left click over an object
to select it. If the control key is pressed while selecting the
object the object is selected in addition to any others currently
selected.</p>
<p>If the shift key is pressed then while the left button is held
down a selection rectangle can be dragged out. Any objects within
this box once the button is released will be selected (DOOM map
designers note - in this instance objects are selected in order
from the lowest numbered object up). If the control key is
pressed along with the shift key then the objects in the box are
selected in addition to any others currently selected.</p>
<p>On pressing the right button a pop-up menu is displayed. If no
objects are currently selected then the menu just has the insert
option. If objects are selected when pressing the right mouse
button (please see the <a href="overview.htm#HOVER_SELECT">overview</a>
to see how the right button can also be made to select objects
the pointer is currently over) then a menu is shown with options
specific to each edit mode.</p>
<p>If the left mouse button is pressed without the control key
and the pointer is not over any object then the current selection
is cleared.</p>
<p>If the mouse has a middle button then this can be used to move
objects once they have been selected. This basically a short cut
for pressing the right button then selecting the 'Move' option.</p>
<hr>
<h2>General Key Commands<a name="GENERAL_KEY"></a></h2>

modes in viDOOM. These are as follows:</p>

displayed with object numbers (and perhaps some extra
identifying information). Selecting one of the objects
from this list will select that object, whereas
cancelling the list leaves the current selection as is.</p>
<p>Note that it may not be possible to see the selected
object in it's selected colours if it is not on top of
the stack of overlapping objects. </p>
<p>Also bear in mind, that though sectors can be moved so
they overlap, and these can be picked using this method,
a DOOM level should never have overlapping sectors.
Unless you want the Cyberdemon to come and take you away
in the night. </p>

</table>
<p><strong>Note 1:</strong> In viDOOM it is not permissible to
delete objects that are still in use by other objects, i.e. it is
impossible to delete a vertex that is still used as one of the
anchor points for a linedef - the linedef must be deleted first.</p>
<p><strong>Note 2:</strong> When scaling or rotating multiple
objects the objects are rotated/scaled around the centre of the
imaginary box enclosing all the selected objects. Also grid
locking is not honoured in this mode.</p>

<h2><a name="SECTOR_MODE"></a>Sector Edit Mode</h2>
<p>For a basic description of a SECTOR see the <a

<h3><a name="SECTOR_DISPLAY"></a>Display in Sector Mode</h3>
<p>When in sector mode the display will look like this:</p>
<p><img src="ed_sect.gif" width="640" height="480"></p>
<p>When in this mode sectors are drawn in red, vertexes are not
shown and things are drawn as a cross just to indicate their
position.</p>
<p>At the bottom of the screen is a box which shows the details
of the sector the pointer is currently over.</p>
<p>Also note that if the tag highlighting mode is enabled any
linedefs that have a tag number matching the one for the sector
the pointer is over will be drawn in white. Note that the
highlighted linedef will not appear if is in a sector that's
selected and highlighted.</p>
<h3><a name="SECTOR_KEYS"></a>Extra Keys in Sector Mode</h3>
<p>The following extra keys can be used while in sector mode.
Keys that work on selected sectors will temporarily select the
sector the pointer is over if no sectors are selected.</p>

<h3><a name="SECTOR_INSERT"></a>Sector Insertion</h3>
<p>When you insert a sector a popup menu is displayed where you
can select a type of sector to create.</p>
<table border="1" cellpadding="3">
<tr>
<td valign="top" nowrap><strong>Create unbound sector</strong></td>
<td valign="top">This will create a sector that is
unbound to any linedefs/sidedefs. It will have a normal
type as defined in the <a

of zero and a floor height, ceiling height and light
level as defined in the <a
href="overview.htm#DEFAULT_SECTOR_LIGHT_ETC">config file</a>.
The floor and ceiling flats will be set to the <a
href="overview.htm#EMPTY_TEXTURE_NAME">empty texture name</a>.
After it's creation the sector number will be displayed
onscreen.<p>Note that no further editing of the sector
can take place until some sidedefs/linedefs have been
manually bound to the sector, as the sector cannot be
visibly selected until they have.</p>
</td>
</tr>
<tr>
<td valign="top" nowrap><strong>Create polygon</strong></td>
<td valign="top">On selecting this you will be asked for
the number of sides to the polygon (3-64). After entering
this a cross hair will be displayed. Press the left mouse
button when the cross hair is over the point where you
want the centre of the sector. Then the sector will be
drawn and you can drag it into shape (defining it's size
and rotation) using the mouse. Note that when defining
the centre and size/rotation that grid snapping can be
toggled on/off and the usual zoom in/out and map
positioning cursor keys are active.<p>You will be asked
then for the following information:</p>
<ul>
<li>A <a href="overview.htm#LINEDEF_CLASSES">class</a>
and <a href="overview.htm#LINEDEF_TYPES">type</a>
of linedef (e.g. scrolling walls, normal,
switches) out of those defined in the config
file. Note that for an HEXEN format map a special
action will be asked for instead.</li>
<li>The new sectors floor height, ceiling height and
light level. If the sector is being defined
inside another sector that sectors floor, ceiling
and light level will already be in the dialog
when it appears. Otherwise the <a
href="overview.htm#DEFAULT_SECTOR_LIGHT_ETC">default</a>
values will be used.</li>
<li>A further linedef type that defines the linedef's
flags, as defined in the <a
href="overview.htm#LINEDEF_DEFAULTS">config file</a>.</li>
<li>The style in which the sector should be painted
as defined in the <a
href="overview.htm#SECTOR_STYLES">config file</a>.</li>
<li>If the sector is being defined within another
sector you will be asked if you wish make the
right sidedef point outwards from the new sector.</li>
</ul>
</td>
</tr>
</table>
<h3><a name="SECTOR_DELETE"></a>Sector Deletion</h3>
<p>It is not possible to directly delete a sector in viDOOM as it
religiously enforces the fact that objects cannot be deleted if
other objects are still bound to them. And once all the linedefs
bound to a sector have been deleted, the sector is no longer
selectable! However, when saving, any sectors that have no
bounding linedefs will be automatically deleted.</p>
<h3><a name="SECTOR_POPUP"></a>Sector Popup Menu</h3>
<p>On selecting sectors and pressing the right mouse button to
get the sector popup menu the following options will be
presented:</p>
<table border="1" cellpadding="3">

<td valign="top" nowrap><strong>Change type</strong></td>
<td valign="top">Changes the sector type. The <a

<p>At the bottom of the screen are three boxes which shows the
details of the linedef the pointer is currently over, and any
associated right and left sidedef. Note that in the screenshot
above the type of linedef is show as the hex number and the <a
href="overview.htm#LINEDEF_CLASSES">class</a> of linedef. This
can be altered in the <a
href="overview.htm#SHOW_FULL_LINEDEF_INFO">config</a> file so
that the linedef type is show as as it's hex number and the name
defined for the linedef <a href="overview.htm#LINEDEF_TYPES">type</a>
in the config file if you are using a display with an higher
resolution. An example of the alterative info for the same
linedef is shown below.</p>
<p><img src="ed_lninf.gif" width="396" height="72"></p>
<p>Also note this if the tag highlight mode is on then if the
linedef the pointer is over has a non-zero tag number any sectors
with the same tag number are highlighted in white. E.g. in the
display above the pointer is over a linedef set to teleport, the
tag indicating which sector the teleported object will arrive in.
The sector above and to the right of the line has this tag and is
highlighted. Note that only linedefs not already selected in the
highlighted sector will be highlighted.</p>
<p>Note that in HEXEN maps the showing of full linedef info
switch is ignored, and the full action special name shown. In
addition to this the special arguments are displayed:</p>
<p><img src="ed_l_hex.gif" width="274" height="110"></p>
<p>Note that in this mode the tag highlighting will be based on
any special action arguments called "tag".</p>

<p><strong>Note:</strong> When prompted whether to fix a

<p><strong>Important Note:</strong> That it may not be
advisable to use this on all linedefs if there are lots
of lifts in the level. viDOOM (due to wanting to remain
completely config file driven for types) is unable to
realise that some textures that look like they shouldn't
be there will come into play when the lift is activated.
This may be changed in the future so that sidedefs that
are pointing into a sector tagged to a linedef of a
specified class are not checked.</p>

<h3><a name="STAIR_CREATION"></a>Stair creation</h3>
<p>This joins the two selected linedefs with steps. Before
starting this option a couple of caveats should be noted:</p>
<ul>
<li>Lines must be non-zero in length and not share any
vertices.</li>
<li>viDOOM assumes that the steps join up the left sidedef of
the linedefs together. This will generally be the case
anyway, and if it isn't remember to <strong>Swap sides</strong>
on the linedefs as required before starting (the sides
can be swapped back once the steps have been defined).</li>
<li>If the linedefs already have a left sidedef, this will be
deleted in preference for the new one facing onto the new
sectors.</li>
<li>Not too much error checking goes on. If you do define the
most bizarre looking steps you've never seen on an
automap before, there is a fair chance they won't work
when you play them.</li>
<li>If the steps pass through a sector, it must be the same
sector.</li>
</ul>
<p>i.e. the following two examples are OK, L1 and L2 can be
joined with stairs:</p>
<p><img src="ed_ex1.gif" width="204" height="97"></p>
<p><img src="ed_ex2.gif" width="204" height="97"></p>
<p>But the following example, where stairs would cross both
sectors S3 and S4 is not allowed:</p>
<p><img src="ed_ex3.gif" width="204" height="97"></p>
<p>(Actually, it would be allowed, but wouldn't look too nice
when you played the level...)</p>
<p>Having got the excuses over with we can now go onto the
process involved with creating the steps. On selecting this
option you will be presented with a display like the following:</p>
<p><img src="ed_step.gif" width="640" height="480"></p>
<p>As can be seen the steps have been drawn and their are a
couple of help boxes displayed. The box in the lower left of the
screen shows the following information:</p>
<ul>
<li>No of steps</li>
<li>The difference in floor height between each step</li>
<li>The difference in ceiling height between each step</li>
<li>The step drawing mode (<strong>Straight</strong> or <strong>Curve</strong>
mode).</li>
<li>Which side is being moved when in <strong>Curve</strong>
mode.</li>
</ul>
<p>On the left is a box giving a quick help on the following
keys:</p>
<table border="1" cellpadding="3">
<tr>
<td valign="top" nowrap>+</td>
<td valign="top">Increase the number of steps in the
staircase (maximum 128)</td>
</tr>
<tr>
<td valign="top" nowrap>- </td>
<td valign="top">Decrease the number of steps in the
staircase (minimum 1)</td>
</tr>
<tr>
<td valign="top" nowrap>C</td>
<td valign="top">Change between <strong>Straight</strong>
and <strong>Curve</strong> drawing mode. In straight mode
straight lines are drawn between the linked vertices on
the two linedefs. In curve mode a curve is defined
between the two points by moving the pointer.</td>
</tr>
<tr>
<td valign="top" nowrap>S</td>
<td valign="top">Swaps between the two walls when
defining the curve of the walls in <strong>curve</strong>
mode.</td>
</tr>
<tr>
<td valign="top" nowrap>R</td>
<td valign="top">Swap which vertices are paired up from
the two linedefs. For instance in the example above
switching the vertices would give the stairs a butterfly
shape rather than corridor seen above.<br>
Obviously, the butterfly effect is <b>not</b> what is
wanted...</td>
</tr>
</table>
<p>After moving the stairs to the position you want you can press
ESC to cancel the process or press a mouse button to lock the
stairs in position and carry on with the creation.</p>
<p>At this point you will be asked if the ceiling should also be
stepped. Selecting <strong>No</strong> means that the ceiling
will stay at a constant height (the highest ceiling height out of
the two linedef's sectors), otherwise the ceiling will be stepped
accordingly.</p>
<p>Now the steps are created. Note that in the created steps the
pegging modes defined for the sector style the stairs will be
painted in is ignored and pegging modes and Y texture offsets
will be set appropriately to line up textures on the sides of the
steps.</p>

</ul>
<p><strong>Tip:</strong> If you select vertices that are
bound to linedefs in another sector, once the creation of
the sector has been completed viDOOM will ask you if you
want to merge the new linedef from the new sector with
the old one.</p>

<h2><a name="MULTI_MODE"></a>Multi Edit Mode</h2>
<h2><a name="MULTI_DISPLAY"></a>Display</h2>
<p>When in multi mode the display will look like this:</p>
<p><img src="ed_multi.gif" width="640" height="480"></p>
<p>When in this mode linedefs are drawn as grey arrows, the arrow
direction corresponding to direction of the linedef - i.e. the
right side of the linedef is on the right side of the arrow.
Vertices are displayed as white points with a grey selection box
around them.</p>
<p>Things are drawn as a circle (indicating their size within the
game) with an arrow indicating their direction. Note different
classes of things are drawn in different colours (these colour to
class pairing are defined in the <a
href="overview.htm#THING_CLASSES">config file</a>)</p>
<p>At the bottom of the vertexes is a box which shows what object
type (vertex or thing) the pointer is currently over and it's
number.</p>
<h2><a name="MULTI_OPERATION"></a>Operation</h2>
<p>Multi selection mode is given just as a way of manipulating
things and vertexes, allowing them to be moved, rotated and
scaled in unison. Note that linedefs and sectors are not
selectable as these are inherently moved just by moving the
vertices.</p>
<p>All keys are honoured in multi selection mode, but keys for
insertion and deletion are ignored. Also the locate object number
keys (F8 and Shift + F8) are ignored.</p>
<h3><a name="MULTI_POPUP"></a>Multi Edit Popup Menu</h3>
<p>On selecting vertices and things and pressing the right mouse
button to get the multi edit popup menu the following options
will be presented:</p>
<table border="1" cellpadding="3">
<tr>
<td valign="top" nowrap><strong>Snap</strong></td>
<td valign="top">Snap the selected things and vertices to

<h2><a name="MERGE_MAP"></a>Merging Maps</h2>
<p>Pressing F3 in any edit mode will allow a different map to be
merged in with the currently edited map.</p>
<p>First you will be asked if you wish to temporarily load a PWAD
and load the first map from it (note that the 'first' map means
MAP01 if editing DOOM II maps, and E1M1 if editing DOOM maps). If
you select <strong>Yes</strong> then you will be prompted for a
PWAD file to read. If you select <strong>No</strong> you will be
asked for a level to load from the currently loaded WADs.</p>
<p><strong>Tip:</strong> The idea of this question is that you
can save PWAD files with a structure you wish to re-use in
multiple maps as the first map. Any linedefs in this map that
have a left sidedef bound to sector number -1 will have the
sector number reset to the sector in which the merged structure
has been placed. Note that if you do insert structures this way
and don't opt to have floors/ceilings automatically adjusted then
it is generally a good idea to check the sidedefs to make sure
they have all their necessary upper/lower textures.</p>
<p>After choosing the map to merge in, a vector display
representing the linedefs from the map that can be moved around
the screen with the mouse is displayed as shown in the screen
below.</p>
<p><img src="ed_merge.gif" width="640" height="480"></p>
<p>On the bottom left is a box giving a quick help on the
following keys:</p>
<table border="1" cellpadding="3">
<tr>
<td valign="top" nowrap>, (comma)</td>
<td valign="top">Rotate the map 1° to the left.</td>
</tr>
<tr>
<td valign="top" nowrap>. (period)</td>
<td valign="top">Rotate the map 1° to the right.</td>
</tr>
<tr>
<td valign="top" nowrap><</td>
<td valign="top">Rotate the map 10° to the left.</td>
</tr>
<tr>
<td valign="top" nowrap>></td>
<td valign="top">Rotate the map 10° to the right.</td>
</tr>
</table>
<p>Pressing ESC will cancel the operation while pressing a mouse
button will place the map where it currently is.</p>
<p>If the merged map is assumed to be a structure (i.e. it has
left sidedefs whose sector fields are set to -1) you are then
asked whether you wish to adjust the floor heights. If you do
select to adjust them then the sector that is in the middle of
the merged in WAD has it's floor height taken. The floors and
ceilings are adjusted in the new sectors so that the lowest floor
is at the same height as the surrounding floor, but the
difference in heights between the new sectors themselves are
maintained. After this you are asked whether to adjust the
ceiling heights. If you do the ceiling height of the same sector
is taken and the new sector's ceilings adjusted to match the
surrounding ceiling (note that ceilings will not be moved if
moving them places them lower than the floor).</p>
<p>You will then be asked whether tags within the map should stay
as they are or be adjusted so that they are different from tags
used in the map being edited. After this the map will be inserted
and then a notice displayed showing by how much the various
objects in the merged map where adjusted.</p>

<h2><a name="LUMP_EDIT"></a>Lump Editing</h2>
<p>Pressing the HOME key provides you with the lump editing menu.
This menu is different depending on whether the map you are
editting is a DOOM format map or an HEXEN format map.</p>
