<A NAME="define-unit-type"></A>
<H3>define-unit-type</H3>
<H4>Description</H4>
Define the unit types in game it is based on the UDTA.<P>
The default unit types are defined in <A HREF="../../data/ccl/units.ccl">
$FREECRAFT_LIBRARY/data/units.ccl</A>. This could also be defined in own
levels. <P>

<DL>
<DT>ident</DT>
<DD>The unit-type unique identifier. It is used to reference unit-types in
game. F.E: "unit-knight", "unit-gold-mine".
</DD>
<DT>name</DT>
<DD>The unit-type name shown in the game. F.E: "Knight", "Gold Mine".
If the name is too long, it is split at space.
</DD>
<DD></DD>
<DT>graphics</DT>
<DD>Defines the graphics used to display the unit-type in game. This could
be an array "#( summer winter wasteland swamp) with different files for the
tilesets. Or an indentifier "unit-xyz" if the graphics from an other unit-type
should be reused.<P>
Examples:
<DL>
<DT>#( "knight.png" () () () )</DT>
<DD>For all tilesets are the same graphics "knight.png" used. </DD>
<DT>#( "gold mine (summer).png" "gold mine (winter).png"
"gold mine (wasteland).png" "gold mine (swamp).png")</DT>
<DD>"gold mine (summer).png" is used for the summer tileset.<BR>
"gold mine (winter).png" is used for the winter tileset.<BR>
"gold mine (wasteland).png" is used for the wasteland tileset.<BR>
"gold mine (swamp).png" is used for the swamp tileset. </DD>
<DT>"unit-knight"</DT>
<DD>The graphics from the unit-type "unit-knight" is also used for the
this unit-type (here paladin).</DD>
</DL>
</DD>
<DT>pixel_size</DT>
<DD>Size of the unit-type graphic in pixeln. A list of X (width) and Y (height)
sizes. F.E. '( 72 72 ), '( 96 96 ).</DD>
<DT>animations</DT>
<DD>Identifier to reference the animation sequences (scripts) for the
unit-type. F.E. "animations-knight", "animations-gold-mine".</DD>
<DT>icon</DT>
<DD>Identifier to reference the icon shown in game for this unit-type.
F.E. "icon-knight", "icon-gold-mine".</DD>
<DT>speed</DT>
<DD>The speed shown for this unit-type in game. (NOTE: this is
only shown and *not* used). F.E. 10, 13.</DD>
<DT>overlay</DT>
<DD>Define the overlay shown if this unit is constructed (build).
Currently are available:
<UL>
<LI> 6 land construction site
<LI> 7 human shipyard construction site
<LI> 8 orc shipyard construction site
<LI> 9 human oil well construction site
<LI>10 orc oil well construction site
<LI>11 human refinery construction site
<LI>12 orc refinery construction site
<LI>13 human foundry construction site
<LI>14 orc foundry construction site
<LI>15 wall construction site
</UL>
NOTE: this will be changed to identifiers sometime.
</DD>
<DT>sight_range</DT>
<DD>Sight range (in tiles) of this unit. F.E. 6, 14.</DD>
<DT>hitpoints</DT>
<DD>Hitpoints for this Unit. F.E. 90, 1000</DD>
<DT>magic</DT>
<DD>Flag to determine whether this unit is a spell user. 0 = false (not a magic

<DT>costs</DT>
<DD>Define the costs to build (or aquire) this unit. It is an array of #(
time gold wood oil) or #(time gold wood oil ore stone coal). Time is in frames
to build this unit.
Gold is the amount required to build this unit. Wood is the amount required
to build this unit. Oil is the amount required to build this unit.
F.E.: #( 200 2000 1000 200 ).<P>
NOTE: This is extendable more costs could be added. (using 6 resources insteed
of 3. Or redefining the gold resource into a crytal resource)
</DD>
<DT>tile_size</DT>
<DD>Define the unit-type size in tiles. NOTE: currently only buildings could
be bigger than one tile. A list of X (width) and Y (height) sizes.
F.E. '( 1 1 ), '( 2 2 ).
