Flat

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

Specifies whether or not this building's or animation's image lays flat on the ground. Normally, the object's Z-axis extends in upward direction in 3D-space. If this flag is enabled, the Z-axis for this object is laid out "flat" in the northwest direction on the XY-plane of reference. The specific algorithm can be found in the coordinate system of this RA2DIY forum post.

On animations, this flag disables the animation's shadow (note that in Tiberian Sun, animations cannot have shadows 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

"and has code for disabling the animation's shadow (in TS animation shadows don't work anyway)"

• In fact, the shadow logic on this tag still works. The actual shadow color will not work. But if you try adding other colors to the shadows. Shadow colors will work as normal.

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

• Shadows of images defined in the Projectile section will be displayed normally.

Bugs/Side-Effects/Unexpected Limitations

• If Projectile has Image=Voxel x any Then Voxel x have Flat=true in the Art.ini or Artmd.ini section will cause Voxel to not work efficiently

• If the vehicle animation Voxel is currently playing. while the unit is tilting will produce strange results.

  Flat=yes (Tilting)

The FLH level can be adjusted or the YDrawOffset tag can be used to resolve this issue.
