SonMapEd (Sprite Mappings Editor)

Another bump, because I dealt with this:

It's not 'fixed' by default because that's a feature, but check the image import settings for a new option.

 

I added 2 new features in SonMapEd 1.04.

1: Rotate Sprite 90 Degrees CCW
The most obvious application of this feature is to create mappings for the horizontal and upside-down walking sprites used in Sonic 1/2/3. This changes the mappings/dPLC positions and size flags, moves the tile art around to match, and rotates the pixels within the tiles. If any other sprites use that same art, it gives the rotated sprite its own section of art data so as to not screw up those other sprites.

2: Duplicate Sprite and Tiles Together
When you want to import an image into a new sprite, now you can use this to duplicate an old sprite into new tiles instead of needing to create all the new mappings again before importing.

 

Tweaker was saying it would be nice if he could change existing tile pieces without adding new ones. I don't see how it's that much easier, but I added a way to do it anyway: hold both Ctrl and Shift and click on a pattern on the top-left to change the piece's size, or a tile on the bottom to change the piece's graphics. You must first select an individual piece using ' and ; unless the sprite has only 1 piece in it.

So... new version, again. 1.05.

He also alerted me to my startling lack of "formal documentation". Since writing documentation is pretty much my favorite activity (or not), I may have some of that ready before the next release.

 

Are you sure? I tried loading tile graphics from the rom extracter and I also tried loading the whole rom as a tile graphics file, and the old art was cleared as usual.

[After further discussion with SMPT, it seems the only problem is that some of the offsets for the rom extracter in offsets.txt extend past the end of the art in question. So it's not a problem in the program, much less in the newest version of the program.]
