Walkable chasm terrain -- need help

[arobinson]

I am trying to write a new user campaign where a mage can turn a chasm (Qxu terrain) into a walkable terrain (a magical barrier of air to let the unit walk across) . Basically I want it to look exactly like Qxu, was probably going to submerge the unit but have a different movement and defense type than Qxu (probably mirror a cave tile - Uu)

I have tried a few things, but it never seems to want to pick up the chasm transitions, and I always get a void terrain with chasm wall transitions on the sides. Here is what I have at the moment that is not working (some lines I tried commented out).

Code: Select all

[terrain_type]
    id=airbridge
    #symbol_image=chasm-tile
    name= _ "Passable bridge of air"
    string=Qa
    aliasof=Qxu
    mvt_alias=Uu
    #mvt_alias="+,Uu"
    #def_alias="-,Uu"
    #submerge=0.4
    #unit_height_adjust=-4
    editor_group=RotE
[/terrain_type]

Is there an easier way to do this (maybe just change the movement type of a terrain in a scenario file)? If not, what must I do to get my custom tile to look like a chasm tile but with a different movement and defense value?

I may have to go with putting in a bridge instead if I cannot get this determined, but I would prefer, for story reasons, to have it be a chasm.

Thank you

Edit of course right after I posted, I got it to work like this:

Code: Select all

[terrain_type]
    id=airbridge
    symbol_image=chasm
    name= _ "Passable bridge of air"
    string=^Ba
    aliasof=Qxu
    mvt_alias="+,Uu"
    def_alias="-,Uu"
    submerge=0.4
    unit_height_adjust=-4
    editor_group=RotE
[/terrain_type]

But please let me know if there is a way to improve on this code (for example the aliasof, should I be setting this?)

Thanks

    def_alias="-,Uu"

That's the best best method of doing what you want that I can think of, and it looks about right to me. That's the way the impassable overlay (^Xo) works, too. The + and - in the alias definitions are redundant though.

Thank you for the feedback, that is all I wanted to know

Hi.
Willing to experiment for a similar problem, I copied arobinson's terrain_type block in a terrain/Terrain.cfg file in my campaign folder:

Code: Select all

[terrain_type]
    id=airbridge
    symbol_image=chasm
    name= _ "Passable bridge of air"
    string=^Ba
    aliasof=Qxu
    mvt_alias="+,Uu"
    def_alias="-,Uu"
    submerge=0.4
    unit_height_adjust=-4
    editor_group=RotE
[/terrain_type]

The terrain characteristics are right but the terrain appears as a black hexagon. How can I fix that ?

What's the issue with placing your walkable chasm terrain on top of the base chasm terrain that provides the correct appearance?

If I put both in the same location in the map file, as ^Ba Qxu, then I have either the right appearance but the tile can be entered.
If I put both as Qxu ^Ba, then I have the black hexagon.

But maybe I don't understand what you mean ?

Is there an example somewhere, maybe in a standard campaign, of this kind of modified tile ?

You can look in the add-on campaign Rise of the Elementalist (scenario: "Further Studies") to see the walkable chasm.

Thanks a lot @gnombat, I was able to make it work with a look at this campaign.

I'll summarize for the next reader stumbling on this question.
Here are the needed parts (in the context of a campaign):

_main.cfg

Code: Select all

{~add-ons/name_of_the_campaign/terrain}

terrain/Terrain.cfg

Code: Select all

[terrain_type]
    id=airbridge
    symbol_image=chasm
    name= _ "Passable bridge of air"
    string=^Ba
    aliasof=Qxu
    mvt_alias="+,Uu"
    def_alias="-,Uu"
    submerge=0.4
    unit_height_adjust=-4
    editor_group=RotE
[/terrain_type]

terrain/Terrain_graphics.cfg

Code: Select all

{TERRAIN_BASE Qxu^Ba chasm/regular}

In maps
Use Qxu^Ba instead of the standard Qxu tile, for example:

Code: Select all

map_data="Gg, Gg, Gg, Gg, Gg, Gg, Gg, Gg, Gg, Gg, Gg, Gg, Gg, Gg, Gg, Gg, Ww, Gg
Gg, Gg, Gg, 1 Gg, Gg, Gg, Gg, Qxu, Ww, Gg, Ww, Ww, Gg, Ww, Gg, Gg, Gg, Gg
Gg, Gg, Gg, Gg, Gg, Gg, Qxu^Ba, Ww, Ww, Ww, Gg, Gg, Gg, Gg, Gg, Gg, Ww, Ww
"

Are you editing the map file manually in a text editor? If so, combining a base and overlay terrain means concatenating them without a space, as Qxu^Ba. If you put a space, the first one will be taken as a location ID instead, not a terrain.

If you edit the map in the map editor, it handles this for you correctly.

Yes, that was the main problem. That's why I added all the files in my answer, because maybe somebody as stupid as me might come later.

Thanks for the detailed explanation, I didn't know about the location ID thing.
