Tilemap Blank Block ID?

Hello guys, I have a small doubt about the new system tilemaps, I was creating a system of random map and realized I didn't know how is the ID for empty blocks. I tried to found out through a text object, but the number that was generated is 536870911, and doesn't work ...

I wonder if it is possible to identify the blank blocks for comparisons.

Thx :)

well, I'm trying to do using array to capture only what I need.

Maybe this will solve partly the problem.

Did you ever figure out the problem? I'm getting the same number output as you "536870911".

Internally, it's -1, but you shouldn't need to use that, just use the 'erase tile' actions instead.

I think it's a bug that it returns that value for the erased tile IDs... might have a quick look and perhaps fix that for the next build.

Thx Ashley, I'm using the array to simulate the values ??for now has worked. (of course, if you have to know the ID of the empty space, the TileMap will be much easier to use, and do not need of a plugin array)

Ditto. It makes no sense

here's my CAPX

Fixed the CAPX to work: as Ashley suggested, adding an "erase tile if array value is -1" action works like a charm. Still, I'd love to see this fixed.

the problem persists if I completely fill an array with -1 and try to retrieve the -1 value by using set tile x,y

to tile array.At(array.CurX,array.CurY)

The array of course is working properly. The SetTile isn't. It returns that weird big number. It's worth a look
