Changing border tiles within a scenario

[Jamie]

I am trying to change a few border tiles within a scenario following the instructions on this page:http://wiki.wesnoth.org/TerrainMaskWML and I am having no success at all after trying many different configurations. Here's my latest effort (with most of the map redacted):

Code: Select all

    [terrain_mask]
    x,y=0,0
    mask="border_size=1
    usage="map"

 _f    , _f    , _f    , _f    , _f   
 _f    , Wog   , Wo    , Wog   , _f      # original map line is  _f  , Uh    ,Wwr    Uh  , _f
 "
	[rule]
	   old=Uh
	   new=Wog
	   terrain=Wog
	[/rule]
	[rule]
	   old=Wwr
	   new=Wo
	   terrain=Wo
	[/rule]
	[/terrain_mask]

I see there is no link to [rule] in the wml reference though there is a place-holder for one. So I have two questions:

• 1) can this code be made to work with some tweak?
  2) is there another way to change the map border from within a scenario?

Here's what I have tried so far:

• the whole map with x,y=1,1 instead of 0,0
  a smaller piece with border=0 with x,y set to cover just this patch
  putting the "old" codes in the mask instead of the new ones
  with and without rules
  moving the location of the final quote mark

Yeah, [terrain_mask] is difficult to grasp, badly documented and possibly buggy.
I think [store_locations] stores border tiles as well. (At least the code in the engine has a with_border parameter.) Then you could just use {FOREACH ...} and make the changes you want with a [switch][case] list and [terrain].

If by “wml reference” you mean the “WML Tags” sidebar, that means that you are on the page that defines [rule].

Thanks for the tip. I'll look into that.

Oh, I see. Yes I found that definition left something to be desired and was looking for something more on the index and syntax pages. I didn't realize it's not linked from the "terrain_mask" page because that's where it's defined! It's helpful to know that it works that way, thanks!
