Flag:	Flat
File(s):	art(md).ini
Values:	Boolean values: yes or no, true or false, 1 or 0
Default:	no
Applicable to:	BuildingTypes, Animations

States if this building or animation lays flat on the ground. This flag helps the game's drawing logic in determining layers and where to draw it.
For animations, this flag also moves the animation 3 pixels up on the Y-axis, and has code for disabling the animation's shadow (in TS animation shadows don't work anyway).

The attack height (the height set by the FLH tag) affects the Flat tag if the H value (from FLH) is a negative value that will affect the height of the animation. The more negative The animation will be much lower (only H=-1 to H=-9 is supported. Values ​​greater than 9 will Make the animation disappear and heard only the sound)

H=-9

The Tiled=yes tag destroys changes made to H values.
tag YDrawOffset can compensate for changed H values The value inside the YDrawOffset tag must be negative equal to the negative H value. Example: H=-9 YDrawOffset=-9

Note

• The Flat tag has side effects. When used with large animations or animations that are too tall
  

Bugs/Side-Effects/Unexpected Limitations
