Heroes 5.5 WarGame Edition - Tactical Edition.

No, catapults and ballistae, for example, are tracked by functions like AttackerWarMachineMove, provided the player can control them; the function does not trigger during an automatic shot. Crystals, as well as walls and hives, belong to the SpellSpawn type; their movements cannot be tracked in principle, but their death can be detected; there is a function for this, as I see, it needs to be checked.
