Hey I'm not sure I'm doing this right, as my tiles arent...spaced right?

So basically as the picture will show the whole tile isnt confined to one square and, I have no idea how to fix this. It’s driving me crazy and I wanna use this program as it allows me to make maps for Pokemon with just Pokemon Assets. This is my first time with the program by the by. It looks as though its by design but when objects are so close I tend to get unwanted bits with it.

Your tileset’s tile size is set incorrectly, this tileset looks like it should have tiles half the size you’ve given them. So, if they’re 32x32, try 16x16.

You can edit this in Tileset Properties, click the Edit button on the Image property to change the tile size.
