Scanning area for certain terrain

[Kal_Ultor]

I attempt the following: If a unit, ID=Builder, is on a hexagon with woods there is an Option in the right-click menu displayed and he can recruit a transport galleon. My code is working. However, I struggle with the summoning position of the galleon which is not working. What I try to do, is that the galleon Spans in a 3x3 area below the keep of my leader, ID=Barbarossa, if there is tropical shallow water. But I can't geht this part to work. I think this is due to a failure in filtering for that area.

Code: Select all

#define Barbarossa_Startlocation
    [store_unit]
        [filter]
            id=Barbarossa
        [/filter]
        variable=Barbarossa_Start
        kill=no
    [/store_unit]

Pointing out that

Code: Select all

#define Barbarossa_Startlocation
    [store_unit]
        [filter]
            id=Barbarossa
        [/filter]
        variable=Barbarossa_Start
        kill=no
    [/store_unit]
#enddef

is never reached.

Filter says that if builder is on tree, all trees can be clicked.

[store_locations] stores location, not x or y. You might need to use radius. There is no guarantee Barbarossa_Start represents start location, its stored when menu item is used.

You might need to use radius.

I don't think so. I think all you need to do is put the x and y lines into one [store_locations] tag. If I understand correctly, that will store the locations you want. That will store 9 hexes in a 3x3 area. Each location will have an x and y in it. I'm pretty sure the fifth one -- which would be $location[5].x and $location[5].y -- will be the center, and you can spawn your ship there.
