First example: mountains

Suppose we have the following map to fill with mountain tiles:

And we have the following images to fill it:

• tile1:
• tile2:
• tile5:

We will use the following three rules to fill the mountains. Beware: Spaces into maps do matter!

[terrain_graphics]
        map="
.   1
  .
.   1
  .
.   1
  1
1"
        [tile]
                pos=1
                type=m
        [/tile]

        probability=30
        no_flag="base"
        set_flag="base"

        [image]
                layer=-1000
                name=tile5
        [/image]
[/terrain_graphics]

[terrain_graphics]
        map="
.
  1
1"
        [tile]
                pos=1
                type=m
        [/tile]

        probability=30
        no_flag="base"
        set_flag="base"
        [image]
                layer=-1000
                name=tile2
        [/image]
[/terrain_graphics]

[terrain_graphics]
        [tile]
                x=0
                y=0
                type=m
        [/tile]
        probability=100
        no_flag="base"
        set_flag="base"
        [image]
                layer=-1000
                name=tile1
        [/image]
[/terrain_graphics]

The first rule, regarding the biggest mountains, will apply first. It will include, with 30% probability, the big 5-tile mountain range. This will make, for example, something like this.

The second rule will then apply. Note that the previous rule had set the "built-m" flag, thus preventing the mountains from the second rule to overlap the place where the first mountains already have been placed. The result will be something like that:

The, the last rule, with 100% probability (the probability key could have been omitted) will apply. It will place a mountain tile on the places where no other mountain tile was placed. The final mountain range will look like that:

Village with a tower

To add a building with a tower that spans over 2 hexes, you may use the following rule (T being the character representing the building hex)

[terrain_graphics]
     map="

T"
     [image]
         name=tower # a 36x72 image
         position=vertical
         base=36,108
     [/image]

[/terrain_graphics]

Reference

Map:

'.' means "this rule does not apply to this hex" (i.e: no image will be set to this hex, this hex will not be checked for flags, etc).

'*' means "this rule applies to this hex, but this hex can be any terrain type".

Flags:

no_flag="built-m" means that the rule only matches if the flag "built-m" is not set.

set_flag="built-m" means that the rule, upon matching, sets the flag "built-m".
