Description of Capx

This test capx has 2 tilemap objects. It loads small one into bigger one. The loaded cells are shown directly, but the unused cells has still drawn.

Steps to Reproduce Bug

• Run this capx
• Touch any tile, the tile ID will show in text object.

Observed Result

The tile ID will return -1 means that it is an unused cell. It works correctly. But the cell still draws.

Expected Result

Draw nothing at unused cell ( tile ID = -1 ).

( The workaround is set the size of tilemap equal to the source tilemap. )

Sounds similar to a bug I reported in the past, which was closed.

I'd prefer seeing the tileAt return the correct id of the tiles that are still being drawn, and also allow offsetting the loading of the tiledata so that you can load sections at different places.

Prominent

It seems not really to be similar. expression:TileAt works correctly, but displaying does not.

Yeah, that is what happens in my case.

We just have different views on how it should be handled. I think it's better to allow more choices to the user rather than limit them.

It is not "limitation".

Since set the size (instance width and height, in pixels) of tilemap could fix the drawing problem, it is better to save and load the size of tilemap.

Yeah, that's true. There are a lot of ways the tilemap object could be improved.

Thanks, should be fixed in the next beta.
