Quick question - am doing a custom sprite for my hold. How do I make parts of it transparent, i.e. round the edges, I don't want my creation to be a square Is there a specific input colour that DROD sees as transparent? Or does the file have to be of a specific time and include transparency?

I think it was something with a .png file and an alpha layer... but I could be wrong.

Most games use magenta though.

Just tried out magenta - it's not that.

Sorry, thought it was grey, due to having Iceworks theme! It looked right! It's actually just having transparency in the PNG.

Use RGB 192,192,192.

I believe it only makes #c0c0c0 the transparency color if one of the corners (Top left? Or was it one of the others?) is set to #c0c0c0...

np: Radiohead - The National Anthem (Kid A)

I think this was the case in 2.0, but was changed in 3.0 so the 192-gray color may be anywhere in the sprite.

I think it was only if any corner was that color.

Using the color Transparent (use a program that can put Transparent in a PNG) will make no change to the current graphics. As in, if you make some 22x22 squares be Transparent and make it be a mod for Tar, then Tar will look exactly the same.

Using the color 192x192x192 will make nothing display to overwrite the current color of said pixel displayed on the monitor. As in, if you make some 22x22 squares be 192x192x192 and make it be a mod for Tar, then you won't be able to see Tar at all, because instead of changing some pixels blue, the pixels will stay gray or green for the ground it's on.

Of course, these are exaggerations. Nobody would want to make a 22x22 square be entirely 192x192x192 or Transparent; you'd only want certain pixels to be those colors.

As Mr. Imer pointed out in the previous post, this was the case in 2.0 but is no longer the case in 3.0. In 3.0, it is not necessary to make one or more corner pixels #c0c0c0 to "enable" transparency in that tile.

Yeah, I've managed to get my custom sprite working with transparency where it should be. No need to use the grey. Yay, I've invented a new creature to battle! A semi-genuinely new one, no other creature in the game moves quite like it.

I believe using grey #c0c0c0 is the officially supported way to do transparency in imported DROD tiles, though. I thought I'd heard of some cases where using PNG transparency seems to work but ends up producing buggy behavior with certain combinations of factors.

How precisely should one use grey #c0c0c0? I've used PNG transparency in 3.0.0 and it works perfectly in all rooms that I've tried it in so far.

Huh. When I use tranparency, I get black. I'm using Paint.Net for transparency, BTW.

I was using the GIMP (Gnu Image Manipulation Program, basically open source Photoshop) and it worked fine.

Based on your history, I feel it's safe to ask whether or not you are using JPEG? You have to use PNG; JPEG doesn't support transparency.

Well, then I don't know what it is. In some programs you need to make sure that you have transparency enabled on the image; I haven't used Paint.NET because there isn't a Mono version (and I don't have Mono installed anyway) and I'm too lazy to compile it myself.

On an unrelated note, I've been looking for something to do, and so I'm compiling Paint.NET under Mono on my computer

You shouldn't have to recompile. I think the problem is heavy use of p/invoke and such, anyway.

Well, so far I've discovered that I can't get the installer to work under either Mono or Wine (without getting .NET for wine).

And the only working copy of the actual Paint.NET requires me to download the SVN versions of Mono and MonoDevelop.

Just install the GIMP

You make the unfair assumption that I don't have it installed. I suffere the same desire as many other advanced computer users - the desire to have more programs than could possibly be nessecary for a particular task.

That sounds good. What happens when you import that file from the Character Management screen?

Huh. That file has an alpha (transparency) channel. Removing the alpha channel made it work. Now I really wonder what DROD is doing here.
