Question Detaching triggers

Detaching triggers was created by Sascha
I'm wondering if I'm doing something wrong with detaching triggers? The help file says this:
Code:
Detach removes a trigger to one instance of a mob/obj/room, for testing or other purposes. The command only removes the trigger temporarily, until the room/obj/mob is reloaded via reboot, zreset, load.

I have a room where after a condition is met, the trigger on the room detaches itself. That part works fine. But the trigger does not come back when the zone resets, either via the regular reset time or via zreset. The trigger only comes back if I go into redit for the room, hit S for script, and then quit out.

In this example, the trigger is in place:
Code:
[22016] Just Inside the Gate [ NO_MOB ] [ Field ][T 22099] A sprawling encampment stretches north to northeast from inside the gate that separates the camp from the forest outside. A barricade surrounds the camp as far as the eye can see, tall enough that it would give an Ogier pause before trying to climb it. To the south is a checkpoint in the barricade that has tall hinged gates that look scarred from years of use. [ Exits: n s ]

Now, the condition has been met and the trigger is detached:
Code:
[22016] Just Inside the Gate [ NO_MOB ] [ Field ] A sprawling encampment stretches north to northeast from inside the gate that separates the camp from the forest outside. A barricade surrounds the camp as far as the eye can see, tall enough that it would give an Ogier pause before trying to climb it. To the south is a checkpoint in the barricade that has tall hinged gates that look scarred from years of use. [ Exits: n s ]

But then at reset it does not come back:
Code:
510H 110M 92V > zpurge Purged zone #220: Zone 220 - Tutorial - Trolloc camp setting. [ (GC) Vivienne purged zone 220 (Zone 220 - Tutorial - Trolloc camp setting) ] 510H 110M 92V > The sun rises in the east. 510H 110M 92V > zreset Reset zone #220: Zone 220 - Tutorial - Trolloc camp setting. [ (GC) Vivienne reset zone 220 (Zone 220 - Tutorial - Trolloc camp setting) ] 510H 110M 92V > l [22016] Just Inside the Gate [ NO_MOB ] [ Field ] A sprawling encampment stretches north to northeast from inside the gate that separates the camp from the forest outside. A barricade surrounds the camp as far as the eye can see, tall enough that it would give an Ogier pause before trying to climb it. To the south is a checkpoint in the barricade that has tall hinged gates that look scarred from years of use. [ Exits: n s ] 510H 110M 92V >

And if I go into redit it does come back:

Code:
510H 110M 92V > redit -- Room number : [22016] Room zone: [220] 1) Name : Just Inside the Gate 2) Description : A sprawling encampment stretches north to northeast from inside the gate that separates the camp from the forest outside.

This might be a regression. It is supposed to reattach based on the configuration in the zone file.

What do you see in zedit in this room?

I feared that was what you'd respond :)

We have two ways of attaching a trigger to a room.

Either, we attach through redit, like you do above, or through zedit, like this:
Code:
[Command list] 0 - Attach trigger name here... [12099] to room

And, set up like this, the trigger will reattach on zone reset - after all, the list in zedit is the basis for the zone reset code.

So, the next question, can we make the other trigger reset as well? Not as easily, no.
I think we might need to add the lines to the zone file when we edit a room trigger list, and vice versa.

The point here is that the list in redit shows a snapshot, so to speak, and the snapshot is saved/loaded on reboot. The zedit list shows a preferred state to return to on zone reset. Once we remove the script attached to the room, there is no record of it ever existing until the next time we load the world files (through redit or copyover).

The "correct" way of doing it would probably be to make redit save to the same list as in zedit, before existing commands for that room, and not save scripts directly on the room.

I've created an issue on github dealing with this: github.com/tbamud/tbamud/issues/47

Meanwhile, with this explanation and by changing affected rooms, this now works as intended. I would not have figured this out with the help files... :) Thank you, Thomas!

The messy problem with this is that when attaching via zedit, the trigger attaches over and over and over again. The zone had been empty overnight and this morning there were twelve of the same triggers attached to the room. Does this hurt anything? I have no idea. Sure is spammy on the eyes, though.
