here is the code in ra2 to create a chemical missile effect:
[GasCloud1]
Image=CLOUD1
MaxDC=60
MaxEC=1000
Damage=50 ;gs
Warhead=Gas
StartFrame=0
EndStateAI=28
Translucency=50
WindEffect=0
BehavesLike=Gas
StateAIAdvance=4
NextParticle=GasCloudD1

[GasCloudD1]
Image=CLOUD1D
MaxDC=60
MaxEC=50
Damage=10
Warhead=Gas
StartFrame=0
EndStateAI=12
Translucency=50
WindEffect=0
BehavesLike=Gas
StateAIAdvance=4
DeleteOnStateLimit=yes

but the image "cloud1"only destroy the units in the centre of the image,if i add cellspread=10 in warhead "gas",it has no effect;how can i use it to destroy the farther units?

increase PercentAtMax=

[xttya]

in waehead "gas"? but if i set PercentAtMax=1,it also has no effect,i mean i want to get the effect as cellspread=4.

then you must create a weapon for you to employ the particle system and warhead you've created.

"Spread=10". to the weapon.
