You're going to hate me for this (again), but deep within Perpetuum is (sadly or not) still a 2D game. If you build vertical walls, it doesn't matter if it's 100m or 100km high, the bottom and the top will still be just 1 tile apart from each other.

oh the things would could do if this wasnt the case

also i hate the look of these "sheer cliff" TF walls. come on people have a bit of style!

PS. I got my Highways & stopped playing b4 they came in & have never used them! ...... Irony much ?

sploit! sploiters!

Need image hotlinking..

You know, you can try to do the same with our base. You r welcome.

There is no obstacle, that's what I was trying to say. If you put a base right at the bottom of a vertical wall, and the top of the wall is passable, then in the eyes of the undocking mechanism it's perfectly fine.

This is again a feature that I've seen before used for defense as a sort of gate (since it has relation control), noone complained then. Now that someone is using it for attacking, it's suddenly an exploit...

And again, wise Alex coming in with solution: introduce "rally point".
"Rally point" works like similar in RTS games: you must define a point where your grunts..err...corpmates will deploy.
It will define itself automatically after terminal was deployed, or modified by CEO.
Rally point should be passable for each bot to any tile what around a terminal. Any terraforming, what intersect or disrupt this passage from terminal to rally point will be restricted. Any weed will not be able to grow there.

Three questions:

#1 I'd like to discuss this as what it is: a group using a forward base to just teleport over walls. Is this a mechanic that is legitimate? Is this is a mechanic that is wanted? If either of those questions is answered with 'no', something should be done about it. If both answers are 'yes' ..... just give us a device we can shoot (independent from LOS) somewhere and use as a tp target (10, 20, 30m ... or however expensive you'd like it to be). The fact that it was used by 'someone' as a gate shouldnt affect this discussion at all here (i, for one, wasnt aware of it, for example).

#2 Why am I being placed roughly 50-80m, on average, from the terminal when i undock, yet the distance CHAOS could teleport was 220+?

#3 Is it intended that there is almost no (?) minimum distance between terminals of different factions?

Edit: I actually like Alexadar's suggestion. A customisable rally point that can be placed in a 100m circle from the terminal would be quite nice.

mqx:

#1 It's not intended but legitimate, as you can defend yourself against it. And since it's not intended, we have to think about how we solve it.

#2 I think you are still thinking in bee-line here, which is not how this works. The top of the wall can be however far from the terminal if it's only a few tiles apart. (Again, the disadvantage of vertical walls.)

#3 I'm sorry, I didn't get that. Which different factions do you mean?

#1 No, it simply requires you to build a few steps into your vertical wall design so the bottom of it gets further away from the top.

#2 There is no vertical tile distance because there are no tiles inbetween. You have to imagine this looking top-down (or by simply looking at the map).

#3 No, I think it is 1000m.

Very interesting. There is, however, a guns vertical angle limitation - how does it work and why a such or similar system can't be implemented to terraforming and stuff?

Here's how we deal with things we find questionable:

Just before our base was destroyed, we found a bug. We tested it, discussed it, and thought it'd be clearly exploitative. It would've allowed us to destroy every single base in the game. no matter how many turrets it had, or what kind of tech they were. So, did we go and test it out in the field cuz we could and no one knew about it? Nope, we reported it, and waited ... not using it for a whole month until it finally got patched.

Now, chaos uses mechanics that arent known to most of us. All i'm asking for are definite rulings on their legitimacy, and limitations. If these tactics are being allowed, i think every corp should know about them. hence the detailed discussion of the details here.

Edit, and i did mean vertical distance. the teleport after undocking placed them around 200m vertical (2d) distance. This isnt considering height and was checked using the radar marker.

mqx:
Here's how it works: a standard terminal has a configured radius of 6 tiles, plus a spawning distance of 1 tile. This means that someone leaving the terminal should appear roughly somewhere between 60m and 70m around the center of the terminal. (1 tile= 10m, but only when it's perfectly flat)

Now, this is only the "perfect situation".

If something is blocking the randomly picked tile in that thin donut around the terminal, then the server starts to search for suitable tiles around that tile in a spirallic way. This way it is possible to get past the above mentioned 70m, but this mechanic is necessary to avoid situations where you are unable to leave a terminal due to the environment.
