Using this code for the ActionDismantlePart

modded class ActionDismantlePart {
    protected override bool DismantleCondition(PlayerBase player, ActionTarget target, ItemBase item, bool camera_check) {
        Fence fence = Fence.Cast(target.GetObject());

        if (fence && GetDayZGame().GetCodeLockConfig().OwnerOnlyDismantle()) {
            CodeLock codelock = CodeLock.Cast(fence.GetCodeLock());

            if (codelock && !codelock.IsOwner(player.GetIdentity().GetId())) {
                return false;
            }
        }
        return super.DismantleCondition(player, target, item, camera_check);
    }
}

But in game, I do not get the option 'dismantle gate' so I most likely miss the box in the model to aim at ?

Maybe the question would be, what triggers the dismantle gate option ? is it a selection in the model ?

So I've gotten a few steps further

I found out I'm not getting the Dismantle Gate (my custom door) option because probably the ActionCondition is not correct even, I think if I understand correctly that the ActionCondition enables the DismantleCondition right ? Does OnPartDismantledServer in the custom door c file validate the ActionCondition for dismantle ?

I've fixed it by looking at classes from Codelock mod, I needed to import some classes to get codelock functions.
