Potentially unwanted behaviour with trebuchets

Game Version:

  • Release (101.101.32875.0)


Trebuchets have some weird behaviour when a group of trebuchets are controlled. When a right-click attack command is issued to a group of unpacked trebuchets and not all of these unpacked trebuchets have the target within their firing range, some weird behaviour will occur.

Reproduction Steps:

  1. Unpack a group of trebuchets in a manner where a target is within range for some of the trebuchets, out of range for others
  2. Issue a right-click attack command at the target
  3. ALL thebuchets will start packing
  • Trebuchets which initially had the target within their range will pack and then sit idle
  • Trebuchets which did not have the target in range, will pack and unpack within the target range (they do not seemingly start attacking the issued target though, just unpack within the range)

Expected behaviour

  • Trebuchets which have the issued target within their initial range will start firing the target and never start packing
  • Trebuchets for which the target was out of range for, will pack, move within the target range, unpack, and start attacking the issued target

Can confirm this for the latest patch as well (version 101.101.32911.0 4395365) running the Steam version.

Actually tested this thoroughly taking unit stances into account. There are 2 possible unit stances for trebuchets; “Aggressive” (this is the default) and “No Attack”. Let’s say we issue a right-click attack on an enemy target.

[1 - POTENTIAL BUG] Packed trebuchets within range of the target will unpack on the spot regardless of their unit stance, but once unpacked, only trebuchets set on “Aggressive” will actually fire! Trebuchets set to “No Attack” will not start firing unless you issue another right-click attack on the target. Not sure if this is a bug or intended behavior but it was consistent in all of my tests.
Similarly, packed trebuchets outside firing range will always move in range and unpack, with only “Aggressive” trebuchets actually firing, and unpacked trebuchets outside firing range will pack, move in range and unpack, once again with only “Aggressive” trebuchets actually firing.

[2 - BUG] If some trebuchets are within range while others out of range, then behavior is consistent with the above if they are all packed. However if the trebuchets that are in range happen to be unpacked, they will always pack and stay idle, while the ones out of range will always behave as described in [1].

[3 - BUG] Different kind of thing, but still on trebuchets, so I’ll mention it in this thread. Double clicking trebuchets doesn’t select all of them if some are packed and others are unpacked (or even if some are in the process of packing/unpacking). For some reason the game doesn’t seem to recognise them as the same unit, but as 2 types, either packed trebuchets, or unpacked/packing/unpacking trebuchets (unpacked = already unpacked, unpacking = in the process of packing).
Specifically, if you double click on a packed trebuchet, only packed trebuchets will be selected. If you double click on an unpacked trebuchet, unpacked AND packing/unpacking trebuchets will be selected. So the game thinks packed trebuchets are different to unpacked/packing/unpacking trebuchets. The intended behaviour should be that all trebs should be selected no matter their current mode (packed, unpacked, packing, unpacking).


As far as I know, 1-Bug and 3-Bug are the same as the trebuchet behaviour in the HD version, so I’m not sure, if this really is a “new” bug. 3-Bug can be annoying, however, I kind of got used to this strange behaviour and always double click on packed and unpacked once while holding down shift… this is not a real solution, I know. :wink:
2-Bug sure is a bug and I can’t imagine that this is an intended behaviour. Might be solved with one of the next patches.

However: I really don’t like the behaviour of trebuchets automatically packing and moving to a target if you place an attack command to ta target out of range. This automatic behaviour might be usefull if you’re attacking; if you use trebuchets for defense, you definitley don’t want that. Really annoying, especially together with 2-Bug…:triumph:


Yes, I am also not a big fan of automatic packing. It often happens, that I want to check, whether trebuchet can attack enemy building, but if it is out of range, then I want trebuchet to continue destroying buildings which are currently in range and only later move larger distance forward to attack several enemy buildings with one packing-unpacking cycle.
Currently I have to constantly press “stop” in order to stop trebuchet from automatically packing, unless I want it to pack-unpack just for moving 1-2 tiles forward for one building.

There was a very popular suggestion in beta forums, that when unpacked trebuchet is selected, then it should should show specific cursor for out of range target. This would allow to easily know, whether trebuchet can attack target immediately or does it need to pack. I think, that this cursor should have appearance of sword + packing trebuchet, representing that selected trebuchet needs to pack. This cursor should also be displayed, if other units are selected along with out of range unpacked trebuchet.

Also when trebuchet starts automatic packing for out of range target, then it should stop packing and start attacking when I right-click on in range target.

I think that this automatic packing feature is in the same boat as new health bars, new waypoint behavior and easy drag military. All these are changes to AOC/HD gameplay and should be toggleable in order to please everybody, including those used to old behaviors. Cysion has said, that QOL changes will be toggleable and automatic trebuchet packing should also be toggleable like those other changes.
Option might be called “Unpacked trebuchet behavior when ordered to attack out of range” and have values:

  1. Do nothing
  2. Pack and attack automatically
  3. Pack and attack automatically when double-right-clicked

Game Version:

  • Build (101.101.33059.0 4403463)
  • Platform (Steam)


In DE trubuchets now automatically pack if you tell them to attack a building outside their attack range. Then they move within range and unpack. However if I have multiple trebuchets and some of them are within range of the target and some of them are outside of it, then all trebuchets pack. Those that were outside the range, now move within range and unpack and attack as expected. However those inside the range pack unnecessarily and stand there without doing anything. The expected behaviour is that those trebuchets which are already within range of the target should not pack and shoot at it directly regardless of whether there are other trebuchets in the selection.

Reproduction Steps:

  1. Create a few trebuchets. Send some of them within range of an enemy building and keep some of them outside of it.
  2. Unpack all of them. The ones near the enemy buildings should be able to shoot.
  3. With all of them selected, give a command to attack an enemy structure. All of them will pack.

Here 2 trebuchets are firing at the castle and two are not.

I right click the enemy castle with all of them selected. All of them pack.

Now the back trebuchets move ahead and start upacking while the front ones stand there and do nothing.

This bug is still present and very frustrating. Also, this is not ‘potentially unwanted’ behavior. this is a bug. clear as day. I suggest renaming the thread to reflect this.

I’ve noticed everyone’s descriptions are a bit long winded and confusing.
So to summarize:
When targeting an enemy unit/building with unpacked trebuchets; if ANY of the selected trebuchet are out of range of selected target, ALL trebuchet will pack and only the one outside of range will move, unpack and attack. attack stance makes no difference for this particular bug.

Easily reproducible. in my example I used the scenario editor but this happens in any game mode as far as I know.


Thank you for reporting this.

Came here to report this myself.
This needs fixed, I lost an ‘army’ of 20 trebs to a few onagers due to this nonsense.
Back trebs in range, Front trebs target is too close, “lets pack ALL the trebs selected so we die like morons”.
Enemy moves away. Front trebs in range. Back trebs target is too far, “lets pack ALL the trebs and not attack anything like morons”.
Ok, let me try to only select the ones in range, nope, still one out of range, which one is it, nope not that one, nope not that one, nope not that one, nope not that one, nope not that one, aaand im dead.

it seems the devs aren’t really interested in fixing the plethora of problems STILL present in this game. hopefully this is due to focus on aoe4, and that aoe4 will be the saving grace. Though I hope for everything, I expect nothing.

Very well said. I have been playing all versions of AOE II starting from the original release in 1999 and this is the most annoying “feature” of AOK DE. I don’t want my trebs to auto-pack; any chance this will be made an option rather than a mandatory “feature”. Thank you.

A post was split to a new topic: [36202] Trebuchets unpack before moving into range of their target

Treb vs Treb/bombard canon combat? No longer effectively possible due to the “auto pack feature” in AOK DE

How you used to be able to play in AOK/AOK TC/AOK HD

Yeah, would like if auto pack feature would be optionable. Especially good would be to have mouse cursor automatically indicating whether trebuchet target is out of range.

When right-clicking on out-of-range target, then it should be possible to cancel unpacking and change target by right-clicking on in-range target. Instead I have to press “stop”. This is quite annoying and I prefer how trebuchets worked in AOC/HD.


@GMEvangelos Have developers considered making trebuchet automatic packing for out-of-range targets feature optionable, like many other QOL features? Or even better would be to get cursor for out-of-range targets :slight_smile:
