WML trigger action for each Gg^Vov

[vorwi]

Hi

My goal is to make big trees to work as villages on my map
but I can't use "village overlay" on big trees cause it make them dissappear

So I came up with solution to put that overlay over grass(Gg^Vov)
and then put image of the big tree like this:

Code: Select all

{PLACE_IMAGE "terrain/forest/great-tree-tile.png" 5 3}
{PLACE_IMAGE "terrain/forest/great-tree.png" 5 2}

I'm not going to do this for each tile by hand
and I couldn't find anything like this via google

Is there anyway to do this something like that:

Code: Select all

[terrain_mask]
	map="custom_map.map"
        [if]
            terrain=Gg^Vov
            [then]
            	{PLACE_IMAGE "terrain/forest/great-tree-tile.png" $x $y}
		{PLACE_IMAGE "terrain/forest/great-tree.png" $x $y-1}
            [/then]
        [/if]
[/terrain_mask]

Thank You

[store_locations] with a terrain filter to an array, then use for/each?

[store_locations] with a terrain filter to an array, then use for/each?

Can I store whole map?


Could You show me your idea with example?

[white_haired_uncle]

Code: Select all

[store_locations]
        terrain=Gg^Vov
        variable=big_trees
[/store_locations]
[foreach]
    array=big_trees
    [do]
        {PLACE_IMAGE "terrain/forest/great-tree-tile.png" $this_item.x $this_item.y}
        {PLACE_IMAGE "terrain/forest/great-tree.png" $this_item.x $this_item.y-1}
   [/do]
[/foreach]
{CLEAR_VARIABLE big_trees}

Of course, you may need to modify the second PLACE_ITEM line, I can never keep track of where you can use an expression like that and where you need to express it differently.

Thanks!
You are amazing!

Now it works

Here's the final result in case someone bumps into this topic with same problem:

Code: Select all

[event]
        name=prestart
        [store_locations]
            terrain=Gg^Vov
            variable=big_trees
        [/store_locations]
        [foreach]
            array=big_trees
            [do]
                [set_variable]
                    name=y_sub_1
                    value=$this_item.y
                    sub=1
                [/set_variable]
                {PLACE_IMAGE "terrain/forest/great-tree-tile.png" $this_item.x $this_item.y}
                {PLACE_IMAGE "terrain/forest/great-tree.png" $this_item.x $y_sub_1}
            [/do]
        [/foreach]
        {CLEAR_VARIABLE big_trees}
        {CLEAR_VARIABLE y_sub_1}
[/event]
