Here is some code for a town portal scroll. The name and ui Name can be changed for the name of the town teleporting to.
The coordinates in set teleport target can be changed to where you want to go.

The first number is level then x then y then elevation.

I can not find a way to deactivate the teleporter after it is used though.

dX,dY = 0,0 --Targets Party's cell if cast on a wall
end
--spell cast and tagged for the champion who cast it.
spawn("teleporter_1", party.level, party.x, party.y, party.facing, party.elevation).teleporter:setTeleportTarget(1,27,19,0)

Why not, instead of spawning a portal, have the scroll set the parties location to where you intend it to teleport the party to?

If you want the town portal to work like in Diablo where you can go back, add a teleporter in the editor near the place where the scroll brings the party to, and have the scroll find that teleporter by name, and just set its position to where the party used the scroll.

I tried to have setPartylocation but I guess I did not get the code exactly right.

I don't know where you came up with this, but this function doesn't exist...
Make sure whatever you're trying to pass is written here or somewhere here.

What you need in your situation is this:

Would this be correct?

defineObject{
name = "ratanscroll",
baseObject = "base_item",
components = {
{
class = "Model",
model = "assets/models/items/scroll_recipe.fbx",
},
{
class = "Item",
uiName = "Ratan Town Portal Scroll",
gfxIndex = 456,
weight = 0.3,
stackable = true,
traits = { "potion" },
},
{
class = "UsableItem",
sound = "teleport",
onUseItem = function(party)

party:setPosition(27, 19, facing, elevation, 1)




end


},
},
}

You're attempting to return a variable and not a value.
If you want to get the parties facing, you'll have to do party.facing , same goes to elevation. (Although I suggest elevation to be set, to prevent the party from falling from hights or getting stuck in the ground.)

party:setPosition(27, 19, 0, 0, 1)


?

Yup.

You could use party.facing to get their current facing.
