Lots of map links have been renamed to "Link" so I thought I'd put together a small tutorial on how to deal with that.

In the traditional way to write logic for moving between maps, you might write something like this:

function onPathAction()
    if isPokemonUsable(1) then
        if getMapName() == "Pokecenter Pewter" then
            moveToMap("Pewter City")
        elseif getMapName() == "Pewter City" then
            moveToMap("Route 3")
        elseif getMapName() == "Route 3" then
            moveToGrass()
        end
    else
        if getMapName() == "Route 3" then
            moveToMap("Pewter City")
        elseif getMapName() == "Pewter City" then
            moveToMap("Pokecenter Pewter")
        elseif getMapName() == "Pokecenter Pewter" then
            usePokecenter()
        end
    end
end

This looks fine and it would have worked in the past, but now, for whatever reason, the link from Pewter City to Route 3 is labeled as "Link".

You might think that what you need to do is call `moveToMap("Link")`, but that's not a good idea for one reason: if there's more than one link on the same map labeled as "Link", it could very easily fail and move to the wrong map.

The solution to this is very simple. All you need to do is hover over the cell that the link is on, and look at the (x,y) coordinate of that cell.





Then you can plug that data into your script, replacing 'moveToMap("Route 3")' with 'moveToCell(65, 33)'

function onPathAction()
    if isPokemonUsable(1) then
        if getMapName() == "Pokecenter Pewter" then
            moveToMap("Pewter City")
        elseif getMapName() == "Pewter City" then
            moveToCell(65, 33)
        elseif getMapName() == "Route 3" then
            moveToGrass()
        end
    else
        if getMapName() == "Route 3" then
            moveToMap("Pewter City")
        elseif getMapName() == "Pewter City" then
            moveToMap("Pokecenter Pewter")
        elseif getMapName() == "Pokecenter Pewter" then
            usePokecenter()
        end
    end
end

Those interested in helping me put together data that Pathfinder can use read below:

Show ContentSpoiler:

To make Pathfinder understand that a link name is invalid, we need to give it a "link exception".

This is done in Pathfinder/Maps/MapExceptions/LinkExceptions.lua

If you wish to make a new exception for a map, you first need to make sure that a link exception for that map doesn't already exist. If it does, add to it, otherwise make a new one. If you make a new one and it already had one for that map, then it will either overwrite the old one, or completely ignore your new one, depending on where in the code you place it.

Anyways, it's fairly straightforward to add to the list. To follow the example above with Pewter City -> Route 3, I added a new exception for Pewter City and gave it a link to Route 3:

...
linkExce["Tohjo Falls"] = {
   ["Route 27_A"] = {23, 32}, -- left
   ["Route 27_B"] = {46, 32} -- right
}
linkExce["Pewter City"] = {
   ["Route 3"] = {65, 33}
}
linkExce["Mt. Moon B2F_A"] = {
   ["Mt. Moon B1F_B"] = {17, 27}, -- left, towards route 4
   ["Mt. Moon B1F_D"] = {38, 40} -- right, towards route 3
}
...

You can create a pull on the Pathfinder repository if you want, or just message me the details here or on Discord.

What an elegant solution. Thanks for the effort and sharing Zonz.
