How do I use Attributes?

[gaveitatry]

I figured out how to put NPCs in the game, but I can't figure out how to use or apply Attributes.  I tried selecting a tile on the Editor and clicking Warp.  It then prompted me to choose which map and x, y coordinates.  I assume that is where the player will end up once they walk onto the warp tile.  And I think that the visual interface window shows which map and x, y coordinates I selected.  But then what?  I don't see an apply button.  In the NPCs tab, you can double click a tile and a spawn image will appear in that tile.  Am I missing something?

The attributes and tiles tabs work similarly in which you must use the Pen tool or the Rectangle tool to place them.

Once you are on the correct tool you can click and/or click-drag where you want the attributes.
