Impassable Terrain?

[Bullethead]

Simple question: how do you make impassable terrain, specifically steep cliffs and mountainsides? Units seem to be able to scale near-vertical hills so maybe you have to use a certain texture? If so, what's the number(s) of the texture(s) that make tiles impassable?

Thanks.

You have to use a cliff texture: 46-50, 63-67, 171-178.

Wow, an answer from The Man http://www.totalwar.org/ubb/smile.gif

Thanks, I'll give those a try. I'm trying to make a map of Helm's Deep from The Two Towers and it was disappointing when the orcs could climb the mountains to outflank the fortress http://www.totalwar.org/ubb/smile.gif

Well, this goes to show that a little knowledge is a dangerous thing.....

Again, I'm making a map for Helm's Deep from the Two Towers. This basically involves a castle in a canyon with sheer cliffs on both sides. The main castle wall is kinda shaped like a Y. The forked end butts into the cliff on one side of the canyon and the single end stretches across the valley floor into the cliff on the other side. Each segment of the Y has a gate in it. Inside the forked end there's an inner U-shaped castle wall, with a gate in the bottom part, surrounding a tower. From cliff to cliff, the canyon floor is about 8 tiles wide at the castle.

Before I knew which textures to use for the cliffs, troops could walk anywhere on the map, including on the nearly vertical cliff sides, and through the gates in the walls. However, once I applied the cliff textures, things got really screwed up. Now most of the valley floor, which is tiled with the default grass texture the map started with, is impassable. Troops can't even get to the gates now--a red X appears as the cursor gets close to them while still over the grass.

The actual cliff textures in the list above (I used only 171-178 for the snowy mountainsides) come no further down than the sheer parts of the cliffs. Then I blended the rocky stuff into grass using the appropriate textures (IIRC, #s in the low-mid 60s). But there are no cliff textures on the valley floor where the troops are supposed to be able to walk.

I tried moving the transitional, non-cliff textures up the sides of the canyon. This looks weird and also produced no effect on the impassable areas on the valley floor.

So what's going on?

Thanks.

We scan the map for cliff obstacles and make ellipses out of them. You can see them on the radar as grey ovoids when you load the map up. What's probably happened is that you've got two sets of cliff textures touching at right angles, and the game has made a single ellipse which contains all of them and a whole lot of 'accessible' ground besides.

It's not easy making cliff maps :)

AAAARRRGGGHHHH!!!!! http://www.totalwar.org/ubb/mad.gif This doesn't sound good.....

I do have 2 sets of cliff textures but they never touch. They run N-S up the edges of the map and always have at least 2 tiles between them even at the narrowest part. The canyon is sorta venturi-shaped, starting at the SE and SW corners and tapering to the narrows about 4 tiles below the center of the N edge, then opening out a bit before hitting the N edge.

Despite this, the gray ellipses run E-W along the N and S edges of the map. They almost meet in the middle, so the only passable space on the canyon floor is right in the center of the map http://www.totalwar.org/ubb/frown.gif

So what can I do to fix this? Must I start over and make the canyon run E-W? But if I do that, will the ellipses then run N-S so I'll have the same problem?

So I see. But why does it have to be that way?
