Hi,

![](https://canada1.discourse-cdn.com/flex035/uploads/mapeditor/original/2X/2/27fcda463f0069863909c220a0a0637a8c1d88de.gif)

does Tile Collision Editor should work this way? I able change x,y, width and height of shape in Properties View but this is not what I expected.

Tile size: 192 x 256  
Tiled v. 1.0.3

Have a nice day 🙂

You must have enabled _View \> Snapping \> Snap to Fine Grid_. Try setting it to _Snap to Pixels_ (or _No Snapping_, to disable snapping completely).
