How do I rip a Tileset correctly?

(1/1)

OhNoezEinPandy:
Hello Everyone,

I just started on working on my first own project in Game Maker 8.1 // yuutuu engine.

The problem I have is not that I can't find the options to insert or create a background. It is actually the technique to bring the tiles to the shape of 32x32 pixels.

The technique I tried to use up until now was: go to vgmaps.com -> open the picture in MSpaint -> cut out the whole room out of where I think I have everything I need -> go into gamemaker and create a new background and go into edit -> resize the shit out of it till it kinda matches the 32x32 grid.

The result is often an unsharp/not correctly cutted tileset. Is that the correct way of doing it and I just need to be 100 times more precise? Or is there a much more comfortable way of doing it?

Edit: I think cutting out single tiles pixel by pixel is the best solution for myself currently. But I will appreciate any comment if this is actually the way everybody does it!

This is how I usually go about doing this.

I use a image editor called GraphicsGale.

Then I take a screenshot in whatever game I want to rip the tileset from.
You can also get already made maps from a lot of games here wich speeds up the prossess.

The cool thing about GraphicsGale is you can set up a grid and use the snap to grid tool wich works perfectly for tilesets. Usually they are in 16x16.



Then with the cutter and snap to grid tool, drag and drop everything that looks useful down in one compact tileset. Try to arrange the tiles in a square.



Select all the tiles with the cutter tool and select "All Frames" and "Crop".



And finally, since these are 16x16 tiles you want to double the size. Use "All Frames" and "Resample". Then increase the size by 200% and uncheck smooth.



There you go, a 32x32 tileset. Save and import it into GameMaker.
Hope this helps. Good luck.

Thank you Sephalos!

Your guide and the graphicsgale editor make my work easier by a lot.
