Spread

On Tiberiums

Flag:	Spread
File(s):	Rules(md).ini
Values:	Signed integers: All whole numbers from -2147483648 to 2147483647; in rare cases, only from -32768 to 32767.
Applicable to:	Tiberiums

Specifies the spread rate, in frames, of this Tiberium/ore type. In other words, this flag determines the delay between each spread check. Once this many frames has passed, each OverlayTypes instance of this Tiberium type will roll a dice to determine if they will actually spread. The global flag TiberiumSpreads can be used to disable spread for all Tiberium types for a particular game or map.

On Warheads

Flag:	Spread
File(s):	Rules(md).ini
Values:	Signed integers: All whole numbers from -2147483648 to 2147483647; in rare cases, only from -32768 to 32767.
Default:	1
Applicable to:	Warheads
Logic related to Spread, as a whole or in part, is obsolete in Red Alert 2 and/or Yuri's Revenge.

Specifies the radius, in pixels, of each damage falloff step of this warhead. This is measured from the point of impact outwards, in a circle. In effect, the warhead itself forms the epicenter of the explosion.

This illustration shows all damage falloff patterns in Tiberian Sun. On each step from the epicenter, damage is decreased by 50% from the previous step. Note the maximum area of effect and the four corner Cell Spots which are excluded from it.

Bugs/Side-Effects/Unexpected Limitations

Even if MinDamage is set to 0 or lower, warheads are hardcoded to deal at least 1 damage point to all cell spots within the maximum area of effect, excluding some special warheads like EMEffect.
