Get rid of "L" shape when creating walls now!

Finally, an actual good suggestion.

I always liked the idea @SalamanderRobot proposed as the fix.

And I think, ironically, AOE3 has a better walling system. Maybe we could use that too


Yeah its ironic that a more modern game has better mechanics… Like how units can have multiple modes of fighting or realistically use different pop. So ironic

But more importantly aoe3 grid system and the walls are calculated is vastly different.

Im up for it, but GL convincing your pro conservative buddies… Apparently nothing ever needs to change…

I do use L shape wall from time to time. in rare circumstances building turn out the way it is sometimes single command of L shape wall will cover entire area instead of having doing two commands of two straight wall to form L shape.

do not remove this.


Cool, but I like my idea with SHIFT and CTRL better :slight_smile: Middle-mouse button rolling while holding left-mouse button down in the salamander thing feels unnatural. I know of no other games or apps that use this; or if they do, it’s the last thing I’d try, and so have never stumbled upon it.

I don’t need the salamander thing, but the salamander thing is pretty cool

Also, I’m able to completely avoid dropping an L-shaped wall down 100% of the time. (That ability might make me an uber-elite AoE player, then, since it sounds like elite players struggle… based on words above.) I don’t, personally, know why this L-shape thing is such a huge deal… but if the devs add the SHIFT and CTRL modifiers I suggested anyways, then problem solved!

IIRC you mainly play SP… What kind of a troll are you?

People want to optimize this feature for online play, where players have hundreds of apm.

I disagree. I don’t mind “L”-shaped walls and probably want them 30% of the time. I say leave functionality as is; I’m used to it by now, and don’t mind making walls in sections or using whatever workaround(s) is/are required. The game is 20 years old; let’s not get too carried away with changes

Or, better yet (to suit everyone’s needs), I propose an enhancement:

  • Keep the existing functionality as is, but as you’re placing a wall (before you’ve let go of the left-mouse button to place it), be able to hold the SHIFT button to force it straight-shaped or CTRL to force it “L”-shaped. Problem solved! :slight_smile:

What the…

Thank you for the positive messages about the ‘Salamander thing’ :smile:

In fact, I am rather optimistic this could be implemented in the game for the following reasons :wink:

  1. Among the various topics about this walling stuff (Optimal Walling, Option for straight walls, Proposed improvement to wall placement, Age of Salamanders, this topic…), this feature seems to get love from the community.
  2. I do not have access to the code, but I think this feature should be quite straightforward to implement. When a straight wall is not possible, I assume the game is computing the junction point position between the two L-shape segments. In such a case, it could be done just by replacing this part of the algorithm by a function similar to the wall_end_points() defined here (JS section). If it is not the case, it should still be an easy feature to implement (way easier than any pathfinding improvement).
  3. AoE2 developers seem to take into account posts in this forum, especially if asked a lot by the community (so any help in promoting it is welcome :grin:). They even insisted on it in this video posted last week.

This choice of the mouse wheel is from the feedback I received on this topic, in order to be coherent with the gate rotation. The good news is that the gate rotation control can be tweaked in the options. So, it would most likely be the same here.

Here are some video samples: Hera, T90.

The ‘Salamander thing’ still allows to build the traditional L-shape wall (even two L-shape walls, you can test it in the JavaScript above).

PS: Before this post, I never called this idea the ‘Salamander thing’ (but rather the ‘Optimal Walling’… which was illustrated in the Age of Salamanders scenario about different QoL suggestions). But I am perfectly fine if you call this the ‘Salamander thing’ :smile:


The irony isn’t AOE3 being a newer game
The irony is that AOE3 is a bad game with a few good mechanics
The bad mechanics include that multi-pop idea of yours (units with 14 pop for example)

Correct, but you still can implement it

Unfortunately, that’s just your mindset
If you mean the balance topics that propose unbalancing units or mechanics that will automate stuff, then yes, the community is right to disagree.

Also, always the majority matters, not one person

Sorry to burst your bubble, but it turns out I play online multiplayer much more than SP with AoE2 DE. In fact, I can’t remember the last time I played it SP. With HD, I thought about it more, it was probably 35% SP. My apm is just fine, thank you… and no matter if it is SP or MP, the goal is the same – winning. I don’t magically play slower when playing SP. If there’s any issue with predictably placing wall shapes at present, I chalk it up to one of AoE’s charming quirks. But as a compromise, I gave a perfectly viable and sound solution. I fail to understand why anyone would be opposed to it, since it solves the very issue the thread points out and several others confirm as a problem.

I don’t appreciate being called a troll for having one sarcastic line. Keep it civil.

What parts of my words were confusing to you? I had actually tested my propsed mechanic in-game a handful of times – pretending and visualizing that my proposed functionality existed – and it seems like it would work perfectly well and would be a user-friendly idea. Did you actually physically try it or take a moment to truly visualize it?

In my testing, because my apm are so high, I hit a > v > s (hotkeys to build a wall in Dark Age), then envisioned what would happen while pressing SHIFT or CTRL key while holding the left-mouse button down to build the wall.

  • If using SHIFT, the wall would always snap to a straight line. If you moved your mouse, the straight line would snap to achievable angles. Let go of left-mouse button when you’re satisfied. (Much like in Photoshop where you hold a key to make a brush draw a straight line a d use your mouse/pen to specify the direction and angle of that straight line)
  • If using CTRL the shape would always be an L-shape. And while holding CTRL and left-mouse button down, where you moved your mouse would guide the direction and distance of where the wall would get placed. When satisfied, release left-mouse button.
  • If not using SHIFT or CTRL, the wall-building mechanic works how it has always worked. So, it remains expected behavior for those who are used to it for 20 years and prefer it over some forced alternative.

I fail to see how or why my idea would induce a, “What the…” response. Unless you didn’t really try it out or take a little time to visualize better; or, are just averse to fine-tuned/precise/predictable/user-friendly actions being possible with keys that are presently not used when placing walls. You’re welcome to disagree, but be a little more productive and civil, and a little less spammy

How would queuing commands work? Might have to change that shift key.

Im sorry your method sounds overly convoluted for what should specifically be a simple task.

Just have a setting in options. Job done. “everyone” is happy

It maybe only looks convoluted because I wrote a bunch of words to try and describe/clarify it for you, other readers, and devs. I’m sorry, but I don’t know you so don’t know how good your imagination/visualization skills are. But some people struggle with that; which isn’t bad, but it’s just a part of life; and those people often just need to see/experience ideas in-action (rather than words) to understand or have it sink in. Design and technical documents are often much longer with their text descriptions than tweet-length forum posts, and that doesn’t make them convoluted. I have a feeling you’re latching onto the number of words I wrote and immediately labeling it as ‘convoluted’ just because of that, rather than trying to follow and truly visualize the concept. Next time you’re in-game, start making a wall and hold SHIFT or CTRL down. It isn’t hard or convoluted.

Queuing can still be SHIFT. The SHIFT and CTRL for wall-building would only get activated while you’re in the process of building a wall. Not sure how that is so unclear? (While you are holding the left-mouse button down to show the game where you are thinking about building a wall (which is present gameplay functionality), you could press SHIFT or CTRL depending on your desired shape and the preview shape would dynamically snap to where it would go, depending on where you drag your mouse. It doesn’t seem very different from ‘the salamander thing’, if I’m understanding the salamander thing well enough… just more predictable shapes and use of SHIFT and CTRL rather than middle-mouse wheel.)

Setting in Options would be an inflexible archaic way that doesn’t please everyone. Like I said, I like that the present way allows either L-shape or diagonal, depending on where and how you move your mouse. I can’t be the only person who is okay with it. Furthermore, if you lock it to “L” via Options menu, you then can’t make straight lines, and vice versa? How in the world is locking it down like that better than my idea, or the salamander thing at that, and pleasing to everyone?

I don’t know what’s more bizarre.

That you say you deliberately want L shapes 30% of the times. L shapes are nearly never the most efficient solution.
That you can avoid unwanted walls 100% of the times. Really unlikely if you play at any decent tempo. It happens to me every game.
That you want to put the overall agreed intended behavior behind shift instead of the other way around. Doesn’t make any sense.

It’s like I’m reading the message of an alien.

  • If not using SHIFT or CTRL, the wall-building mechanic works how it has always worked. So, it remains expected behavior for those who are used to it for 20 years and prefer it over some forced alternative.

If neary everyone agrees then it’s not a forced alternative… Actually it’s the other way around. Everyone is forced to use this suboptimal algorythm.

Given that my issue most often is that only the last tile gets 2 walls next to eachother instead of the intended straight line, I’m not sure if Salamander’s suggestion will fix this.

I believe it’s most likely that they just remove the L algorythm, since that is the least effort and has to happen anyways if implementing Salamander’s suggestion. But if they choose to implement the latter I would see it as a clear improvement.


What I like the most about your suggestion is that it dynamically becomes the most used diagonal when you make a fully diagonal mouse drag, so it basically simplifies the walling system from this weird 2-faced algorithm into a single, simple system. I only dont know wether it would be best to start the diagonal at the start vs end point, but I guess you could make both accessible through scrolling but have the diagonal at the end as the default system.

Thank you all for taking the time to create and discuss this important topic! I can confirm that it is on the radar of the team as an oft-requested improvement, though I can’t say whether or when changes would be made. So for now, keep the conversation constructive and keep your eyes open for possible changes in the future! :+1:


I have a feeling the glitch being experienced is sometimes due to Internet lag or instability. No matter how smooth the game looks, I doubt it’s able to transfer all commands and algorithms going on 100% of the time with 100% perfection. Just a hunch I have, but possible. I can see it as a possible cause of the example SalamanderRobot posted for Hera’s occurrence, but not T90’s so much. In Hera’s, we see the L-shape briefly. That might have been the last time the cloud/game registered Hera’s shape desires (if he had some Internet data packets lost) until he let go of the mouse button. I don’t know, though. I don’t know how the game was coded or how commands are executed and sent to the game/cloud. It’s neither here, nor there, since GMEvangelos says they’re looking into it.

  • Similarly… sometimes when I instruct villagers to make a building and they instead sit in the foundation of it when I check back a minute later, I’ve felt that might be due to Internet lag/instability of some sort… because I’m pretty sure I never have that happen in Single Player games. Yet it happens almost every multiplayer match.

If it happens to work perfectly well in Single Player games not on a server (which is worth testing), then surely it must have something to do with internet lag, no? I’d be curious if anyone sees this errant wall-creation behavior in single player games.

If there’s a bug, obviously getting it fixed will be great.

People can and do play the game differently than you and people you watch on YouTube :smiley:

Truth be told, when I was writing the idea, I started to say let’s make the default be a straight line only, with SHIFT or CTRL as the modifier to make an L shape. (Personally, this would be my preference.) But as I thought about it more, the game does have a 20-year history, as always gets pointed out. So, maybe there are people who like that the game presently has a dynamic ability to go straight or L-shaped without having to hit a modifier key (as I don’t mind too much). Plus, maybe some people don’t like using the keyboard at all (or rarely) and so don’t have their hand constantly hovering over it like I, and probably you, do.

If a modifier key could be added, then I’ll leave it in the devs’ capable hands to decide if they want (a) ‘straight line only’ as the default with a modifier key to make the L-shape, (b) to do what I mentioned above, ( c) some ‘salamander thing’ solution, or (d) some other solution. As I said, my preference would be (a)

Thank you for sharing this, I am very pleased to learn it is on your radar! :smiley:

In case the developers team is interested, you can forward them this post explaining the core of this algorithm, but also this CodePen page with the demo and all the code freely available (the main logic is written in the wall_end_points() function in the JS section).

I did not exactly understand your example. Could you maybe post a screenshot of this? You can for instance use the ‘Salamander thing’ tool with the Clear Map and draw options to draw something describing it. :wink:

This choice is already available in the ‘Salamander algorithm’ :wink:
I just made the diagonal at the beginning as default, but this is just an arbitrary choice.

For the solution (a) ‘straight line only’, I assume you refer to something similar to what is implemented in AoE3.
I don’t know the code of AoE2DE, but I think this solution would be very difficult to implement.
Even if still using the buildings grid system to define the wall end points, this would mean that there are a very (very!) huge number of angles possible for the walls (given that walls can take all the map size).
AoE2DE is still using a 2D rendering system (see here for explanations about AoE1DE). It means that you would need to store (and load in-game) as many renderings as there are possible angles (increasing a lot the size of the game and affecting the performances on lower-end systems).
If you limit the number of angles, it means you still need a ‘salamander-like’ algorithm to join end points without a correct angle.
The implementation issues do not stop there as this would also impact other stuff like the collision boxes…
On top of that, this is not just a QoL feature, because it would add stuff which cannot be achieved in the game currently.
So, it could be nice, but it seems nearly impossible to apply this to AoE2DE :neutral_face:

To give more information about ( c ) ‘Salamander thing’:
For two wall end points, we can only draw a straight line if these two points are on the same row/column/diagonal (which is properly done in the current game implementation).
For all the other cases, we need to use straight lines connected by an intermediate point (to compute). The game always computes a L-shape in the current implementation.

The purpose of the ‘Salamander algorithm’ is to allow to choose between 4 solutions:

  1. diagonal attached to the first point (then horizontal or vertical) -> optimal in terms of tiles & cost
  2. diagonal attached to the second point (then horizontal or vertical) -> also optimal in terms of tiles & cost
  3. vertical attached to the first point (then horizontal) -> L-shape
  4. horizontal attached to the first point (then vertical) -> L-shape

The game currently only uses solution 3 or 4 (depending on the largest delta in X or Y coordinates).

If I understand properly (b) what you mentioned above, the SHIFT solution is similar to (a) straight line only (see comments above), while the CTRL solution is the game current implementation (always L-shape). In fact, I do not understand what is the difference between the CTRL solution and the ‘not using SHIFT or CTRL’ solution (except if you want to be able of building L-shapes when a single straight line is possible).

Maybe I am missing something. Could you tell me ? :wink:


I don’t have time to clarify much or respond in full, but, no, I don’t want an AoE3-like solution for any of this. I’d just want the game to snap to the possible angles it can make the wall at.

For example, if we go with (a) where straight line is the default, then wherever you drag your mouse, the game will snap the straight wall to its eligible angles to show you where it can be constructed. This is how the game currently operates. The only difference I propose from current game in (a) is that you will never see it go to the L-shape while dragging your mouse around. In order to see L-shapes for (a), you would need to hold SHIFT down. And those L-shapes would similarly snap depending on where youndrag your mouse.

L shape walls have to be removed!!!

Why would you ever make an L shape wall?

Agreed. It’s compounded by how incredibly difficult it is to delete the mistake. You can’t drag-select them, and if you double-click, you get existing walls too. So you have to click one by one. Contrariwise, if the game forced optimal diagonals and you wanted to build an L, all you’d have to do is shift + click two more points — a massively easier operation.


The fact that I’m able to do this in one L-shaped action makes me a very happy AoE2 player…
