I think a simpler solution to the problem of replacing only 1 broken part is to not have multiple object OCLs. Just have each wall object OCL only 1 other wall object or a hub. In this system hubs become functionally redundant and are just there for looks.

Another useful thing to OCL is the gate object, AmericaCheckpoint, which only lets your own team through.

The anti stacking weapon works fine, but i have found you cannot OCL multiple wall segments because then the enemy will drive through your wall as if it does not exist. You can only OCL one wall segment at a time so that the bounding box is recognised.

The anti-stacking weapon is:

Weapon WallCoreWeapon
  PrimaryDamage = 2000.0
  PrimaryDamageRadius = 1.0
  AttackRange = 1.0
  DamageType = LAND_MINE ;does not affect other structures
  RadiusDamageAffects = ALLIES ENEMIES NEUTRALS
  DelayBetweenShots = 5
  ClipSize = 1
  ClipReloadTime = 100000
  AutoReloadsClip = No
End

And the way to use it is to have each wall object fire it (make sure all wall objects use WallArmor and not StructureArmor so that LAND_MINE damage can kill them):

  Behavior = FireWeaponUpdate ModuleTag_NoStack
    Weapon = WallCoreWeapon ;Prevents stacking of wall objects
  End

That way when it is OCLed it will fire the weapon and destroy any previous walls which occupy the same place.

Because of the problem of bounding boxes not working if you OCL more than one object at a time, i suggest you just have 2 OCL upgrades, one that makes 1 wall segment forwards, and one which makes a wall segment backwards, so you can build in a straight line forwards or backwards, one piece at a time.

If you are doing one piece at a time then the anti stacking weapon is not needed.

On second thoughts, if you are doing forwards and backwards OCLs then it is needed because the wall object will have to have UpgradeDie modules removing both upgrades, which makes it possible to stack walls (if you make a piece and build both upgrades to make a new wall in front and a new one behind the piece, and if 1 of those is destroyed, then both upgrades become available again).

Now i am trying to fix problems with my GLA wall, which is supposed to spawn a barrage balloon to blow up any aircraft that try to fly past it. The balloon is not working yet (i think i cannot use SpawnBehavior to spawn it, it will have to be an ObjectCreationUpgrade).

I am also going to have angry mob people manning the barracades. The GLA wall can also be stealthed.

As for the China wall, i am going to make it mined and also use a different w3d model which works better.

And the American wall has a radiation emitter weapon, and the hubs respawn the wall bits in between.

As for the gate object, it cannot be OCLed because the model is facing the wrong way. You could get a dozer to build it separately if you want to use it.
