Modding The Harvester

I don't think what you want can be done in TW. The Tiberium logic has too many hard-coded components, like the docking requirement.

Unless of course the MARV in Kane's Wrath used some long-undiscovered logic from C&C3 to create its drive-and-collect ability.

You could try giving the harvester a dummy weapon that automatically kills nearby Tiberium and receives a bounty for each "kill".

That sounds like a good idea. I don't have the Kane's Wrath expansion so if someone could post the marv.xml file code I could take out the behavior elements that allows it to scoop up tiberium.

Unfortunately the KW files have not been released and cannot be extracted either

I was looking at the xml files for the "bounty" behavior code, but I can't find it. In fact a search shows there's no file with the word bounty in it. Where do I get the "bounty" behavior code from? Turning the tiberium into something that can be killed with a money value doesn't sound too hard...

I haven´t used this code often, only seen it in one of Asuka´s and Stygs´ mods, so take this as more of a rough guideline - it should work this way, but I might be missing something.

First, you have to define the value of the crystals. To do so, add BountyValue="####" (where #### is whatever you want Tiberium to be worth) to the TiberiumCrystal´s and TiberiumCrystalBlue´s GameObject element (the first element that also defines cost, buildtime etc.).

Next, you have to enable the bounty by using an AttributeModifier. It should look like this:

<AttributeModifier
			id="AttributeModifier_TibBounty"
			Category="NONE"
			Duration="1s"
			StackingLimit="1" >
			<Modifier Type="BOUNTY_PERCENTAGE" Value="100"/>
		</AttributeModifier>

Now, all you need is a weapon that applies this to the crystals and then kills them. Make sure to have the Damage triggered after the AttributeModifier though (but before it runs out):

<WeaponTemplate
		  id="TiberiumReaper"
		  Name="TiberiumReaper" 
		  ProjectileCollidesWith  = "ALLIES ENEMIES NEUTRAL STRUCTURES WALLS" 
		  RadiusDamageAffects="ALLIES ENEMIES NEUTRALS" >
		<Nuggets>
			<DamageNugget
				Damage="99999" 
				DelayTimeSeconds="0.5s" 
				DamageType="CANNON" 
				Radius="10" 
				DeathType="NORMAL" >
				<SpecialObjectFilter Rule="NONE">
						<IncludeThing>TiberiumCrystal</IncludeThing>
						<IncludeThing>TiberiumCrystalBlue</IncludeThing>
				</SpecialObjectFilter>
			</DamageNugget>
					  
			<AttributeModifierNugget
				PartitionFilterTestType="SPHERE"
				AttributeModifierName="AttributeModifier_TibBounty"
				Radius="10">
				<SpecialObjectFilter Rule="NONE">
						<IncludeThing>TiberiumCrystal</IncludeThing>
						<IncludeThing>TiberiumCrystalBlue</IncludeThing>
				</SpecialObjectFilter>
			</AttributeModifierNugget>
		</Nuggets>
	</WeaponTemplate>

Add this to the harvester with a FireWeaponUpdate (FireWeaponCollide could work too) and you´re ready to go.

Note that AttributeModifiers seem to have a hardcoded minimum update frequency, so you might have to increase the delays and durations a bit.
