SquirrelEDIT - a 16x16 sprite editor with C bitmap array export

[DW1992]

Hi Everyone,

So, instead of working away at completing the tasks on my wife's 'Honey-Do' list, I decided to write a little utility to help with sprite creation.

Introducing, SquirrelEDIT 1.0
and yes, it's named after my attention span... see the first sentence above...


SquirrelEDIT is a simple 16x16 pixel sprite creator / editor, but with a twist...
It doesn't just allow you to plot pixels on a 16x16 grid, it also generates the exact C code required to place your bitmap masterpiece into an array that you can simply copy / paste into your favourite IDE, like CodeWarrior, etc...


I made this while (continually) working on OPERATION : PewPew!
My side scrolling space shooter game, to make it easier to improve its sprites.

SquirrelEDIT should run on any 68K MAC with 1MB of memory and up, but I've only tested it with real hardware on an SE/30, LC475 and Colour Classic MYSTIC running System 7.x.x
Feedback for other versions / hardware welcome!

All your favourite paint style functions are here..

Flip horizontally
Flip vertically
Rotate clockwise
Add a border
Invert
Line
Bucket fill

Grid on/off
Tile view on/off (for creating a 3x3 grid, updated in real time so make creating tileable icons easier)

Use the arrow keys to move your sprite around the canvas.

You can also Save / Open your sprites for later use.

Here's an example of some sprites I created with it.
All the sprites shown here are included in the .SIT



I hope this helps someone will find this little tool useful.
I'd love to see any sprites you make with it and hear how they are being used in your own code!


Any questions / suggestions / comments / whatever... please contact me!

Updates (if any) will be posted here in this thread.

Very useful. Would it be possible to add color support?

Thanks Maxoakland, I appreciate the kind words and it's awesome that someone may find it useful!

As for adding a colour pallet...
I'm totally open to adding support for colour. Off the top of my head it will change a few ways my code functions, since it's specifically written for 1bit.
Let me do a little thinking and see what I can come up with.

I also received a DM asking if it would be possible to have the selectable option to create 16x16 and 32x32 sprites, which I think would be super handy for higher resolution systems requiring larger sprites.
I think if I'm changing it to include a 32x32 option, it would also be the ideal time to add support for a colour pallet and maybe a few other standard drawing tools, like undo, circle, and region select / move (assuming I can figure out some of the maths behind that...)

Thanks again!
I'll post updates ASAP.

I wrote something similar for Microsoft Basic in about 1992, and used it to develop a game called CrossFire (and I'm fairly sure that that name isn't unique either) that was distributed on one of TheMac cover CDs. Not that I've been able to find it since I lost my own TheMac collection. But if you fondly remember a space invaders style game, played by mouse, where you have two shooters and you only get the kill where your shooters missiles intersect, and if you played that game on your black and white Mac, and if that game was only marginally better than rubbish (definitely not my finest work, but I was young!) then you may have been playing my game. And if you have a copy of it, please could you upload it? I haven't seen it in nearly thirty years! In any event, neither my sprite editor nor CrossFire were a patch on SquirrelEdit and OperationPewPew.
