Title: Finding Units On A Tile
Post by: Sirbomber on July 15, 2010, 12:07:15 PM

Hey, does anyone know if there's a way to check what type of unit is on a specific tile?

Note that I'm not talking about simply detecting any unit on a tile using a trigger.  I want to check a specific location and grab the mapID of the unit on that tile (or return mapNone if no unit is there).

I don't know of any good way either.

I currently do it by running a RectEnum on one tile (the centre tile for buildings) and using GetNext(<unit>) to get the handle.

What militates against using a LocationEnumerator ? Im using it and it works for me.

What im using is something like

Code: [Select]

LocationEnumerator SpaceportEnum(LOCATION(tr.Location().x-2, tr.Location().y-1));
if(SpaceportEnum.GetNext(unitontile))
{
[Stuff, in my code i checked if its a spaceport with unitontileGetType()]
}

HFL, or the old GetTile hack. If you go HFL, use GameMapEx::GetTileEx, and check the tile.unitIndex field. I dunno how that works for structures (if at all), though, but it works for vehicles. A LocationEnumerator would probably work as well.

Oh, I should probably commit my HFL fixes (which includes a fix for the aforementioned function, which was horribly broken) to the SVN...
