How do I change the fuel-air bomb explosion into a nuclear one with the effects same to China's nuclear missile?

You'll need to go into WeaponObjects.ini and change DaisyCutterGas.

Taking a bit of a guess, this:

Behavior = SlowDeathBehavior ModuleTag_04
DestructionDelay = 1000
DestructionDelayVariance = 100
FX = INITIAL FX_DaisyCutterIgnite
FX = FINAL FX_DaisyCutterFinalExplosion
Weapon = MIDPOINT DaisyCutterFlameWeapon
Weapon = FINAL DaisyCutterDetonationWeapon
End

Should become this:

Behavior = SlowDeathBehavior ModuleTag_04
DestructionDelay = 50
FX = FINAL FX_Nuke
Weapon = FINAL DaisyCutterDetonationWeapon
End

this is Generals and not zero hour, right?

so there is no weaponobjects.ini in the directory

Ok then, for generals it's in FactionUnit.ini. Same change though.

---

Now this time, how do i change what unit the paradrop sends in? Like tanks or tomahawks would be great.

ObjectCreationList.ini. Search for SUPERWEAPON_Paradrop

---

Now what do I do to change the unit type? And How do I do multiple unit types in one drop?

Replace AmericaInfantryRanger with whatever you want. You can find the full name of each unit by searching for it in factionunit.ini


Make another payload line.

---

Please specify how to make another payload line.

How do I make another payload line, Specifically?

Copy and paste the line with payload written in it...

---

Now how do i seperate them each?

Now for the superpowers themselves: Can I make the US have the nuclear missile silo? I know this isnt a superpower but I need to know if it works.

yes, you can , but actually, the US have the nuclear missile silo. the superweapon general already has (supposed to), but she only has the particle uplink cannon in the game. Go to superweapon.ini to look for the data for super weapon general, and scroll down to find america neutron missile something like that (NOTE: there is another called cruise missile, dont find that one). I think the neutron missile is in the second last. Just change the prerequisites and add
SupW_Command_ConstructAmericaNuclearMissileLauncher
to your USA command set.

if you are doing this on generals, then just add the Command_ConstructChinaNuclearMissileLauncher to your USa commandset
