[Solved] Undeclared function IsTerrainWalkable

[APproject]

Hey.

So I imported a spell from a Spell section. It has this code among all of the code:

        if IsTerrainWalkable(x1, y1) then //If the terrain is passable the you'll dash, if not then trigger ends.
            call SetUnitX(caster, x1)
            call SetUnitY(caster, y1)
            set cur_dist = cur_dist + Offset //This counts how many times you've moved.
            call SaveReal(udg_Rush_Hash, id, 2, cur_dist)
        else
            call PauseTimer(t)
            call DestroyTimer(t)
            call DestroyGroup(g)
            call SetUnitAnimation(caster, "stand") //Resets the animation.
            call FlushChildHashtable(udg_Rush_Hash, id)
        endif

When saving the map JNGP gives me errors saying Undeclared function IsTerrainWalkable, also another error points to endif saying Cannot convert null to boolean.

I don't have a lot of knowledge on Jass, almost none. I tried to google it up, I found that this function is based on vJass. In the base map from which I copied this, it works, when I copied to another map - not. How to solve this so that map runs properly without errors?

Thanks.

Which spell? What error is it giving you on the second map?

Make sure you have all the required libraries for the spell.

 

[DracoL1ch]

find that func in the source map and copy it too, obviously

Give us the link to the spell.

Are you normally working with GUI or why do you struggle using JASS/vJass?

IsTerrainWalkable is a function from library TerrainPathability. You'll need this library in your map,
so your code can draw on it.

This is the spell.

Errors happen on my map, original map has no errors, same coding though.

I work with GUI mainly. So I need to copy this library code to my map? Test map is not available there.

EDIT: Oh, I copied the code into the map and now it works perfectly. Library was missing after all. Thanks a lot.

Good to hear.

Just ask if you need help with the spell configuration or if you run into
unexpected bugs.

Mmmh such code is in my beloved spell section. That's alarming.

I am guessing the spell code was in a scope instead of in a library and so you didn't get an explicit "missing library" error. This is a good reason to always use libraries instead of scopes in vJass.
