dummy object attached to a unit

[CrazyGDIfan123`]

whats the best way to attach a dummy object to a unit? this is actually for ra3, but same stuff anyway

the purpose of this dummy object is to have a model which is easily scaled (ra3 exclusive), so i want it 100% fixed on the unit without any tendency to move independently

I'm not familiar with Red Alert 3 scripts, but try this attach update:

<AttachUpdate
id="ModuleTag_Attach"
Range="500"
CloseEnoughRange="20.0"
Teleport="true"
UseGeometry="true"
DetachWhenParentHealed="false"
ScanForNewParentWhenDetached="false"
DetachWhenParentOutOfSlavedRange="false"
InitialAttachDelay="0.0s"
ParentStatus="CAN_ATTACK"
Flags="FIND_BEST_PARENT UNCONTAINED_ONLY SAME_PLAYER_ONLY"
>
<ObjectFilter Rule="NONE" Relationship="ALLIES">
<IncludeThing>*This Object Carrying the Dummy*</IncludeThing>
</ObjectFilter>
</AttachUpdate>

For "ParentStatus" if Can_Attack doesn't suit the needs pick from this list:

Then most likely the Object carrying the attached object would then need to spawn this dummy object. Hope that helps!
