Making Map Tilesets

Step 1: The texture
First you need a texture. You can create it yourself or take it from other games. I make a path tileset. So I create a 768x384 pixel image, and insert the textures. But the area doesn't have to be filled completely.

When you are done you save the image as .png!



Step 2: Koopuzzle
Now you download Koopuzzle here: https://bit.ly/2Znxi0W

Open Koopuzzle go to File > Import Image.

Select your just created image.

And now you can start creating your tileset!

To create an object press "Add".

In the "Object List" you can see all objects you created.

Now click on "Object 0" and cut the area with + and -.

You can also set the "Repeat" setting to define what should happen when the texture is finished. Recommended is Repeat.

Mark the object parts in the box above and insert them by pressing the left mouse button in the area below.

When you have created and edited all the objects you need go to "Object Groups" and press "New Group".

You can name this group as you like and drag the objects into the corresponding group.

Step 3: Import tileset into Koopatlas
When you are satisfied with the tileset, select File > Save as...

Now you save it under a meaningful name like "Mountain Paths" in the Tileset folder of Koopatlas.

Then open Koopatlas, click on "Add Tile Layer" and select your tileset.

And done!

Make sure that you insert your tileset compressed in NewerSMBW > Maps > Texture!
