Angband 64 x 64 pixel tileset

[d_m]

Hi Shockbolt,

I'm not sure when the official version comes out, but I created a special version of Angband for you that supports PNG and has a 64x64 tileset (currently the 32x32 tileset upsampled to 64x64). I didn't want to check the 64x64 tileset into the main branch until we have your actual artowrk.

If you modify the 64x64.png file to contain your tiles it should work. However, this doesn't (currently) support the special 3D walls, so you'll have to create a single 2D block wall for now (sorry). I still hope to get that working but I figured you'd rather have this to work with for now.

Let me know if you have questions.

For any other tile authors: I'm hoping to make it much easier to add new tilesets to Angband--right now the easiest way to create new tiles is to replace a previous tileset at the same size.

Awesome! I've started adding tiles now, using RogerN's previously posted tilepicker

I must be doing something wrong, the tiles come out with a bit of defects.

What I did was open up the 64x64.png file, change the mode from index to RGB (this in order to add my own tiles, as photoshop wouldn't allow additional layers without doing this).
Then I added my own png tiles and save the file as 64x64.png in RGB mode(with a transparent background)

This produce the error seen in the screenshot below. Saving the file with index mode produced a pure white background for the tiles, no transparency.

So the screenshot below was when you saved the file in RGB, or in indexed mode, or both? Did you get any kind of message?

If you can send me the 64x64.png file you're using I can try to figure out what's going on (either in the GIMP or in the loading code). My email is @plastic-idolatry.com.

Sorry for the confusion.

no worries, it's a work in progress for all of us

The above is a screenshot when saving the tileset in RGB. Indexed mode produces a pure white background, even though the background is transparent when saving it in photoshop.

Wouldn't you need to save it in RGBA? No alpha channel, no transparency, after all.

Oh, good point. I think that's probably the issue!

Using photoshop: In RGB mode, you only *get* the option of interlaced or not when saving the file to PNG. I've tried every way I can think of now and still I get the same errors.

Can you convert it from indexed to RGBA before you copy your tiles to it? what do you select to create your tiles?

I have to convert it from indexed to RGB in order to import anything into the 64x64.png tilesheet, unless I do that, I can't add a layer ontop of it.

I discovered that if I paint directly into the RGB using nothing but pure colors, everything works fine when I save the tilesheet as PNG RGB. As soon as I add any of my tiles that don't have a clear colored edge, such as many of the "old tiles" have, it starts messing up, giving off visual defects.

Unfortunately I am not familiar with Photoshop, all I can do is ask questions of what might be needed to convert the file to have transparency.

Do you want me to e-mail the file I made when I sent you those screenshots? It is already 32 bit, so it may be easier to paste your tiles into. However, it is also 9.6 MB. Also, the edges of the upscaled terrain tiles are blended together so show a line. (Same for any upscaled tile where pixels on both sides of the edge are used.)

You could always try and send it to smaugs_treasure (a) msn.com , that one handles larger e-mails, but I'm not sure if it does any good as it's when saving the files that the troubles appear.

Blue Baron:

I unzipped the tilesheet you sent and put it into the Angband folder, and it seemed to work, the tiles looked normal against a black background as obviously it's meant for another version.

But just opening the 64x64.png file you sent me in photoshop, then saving it without any modifications to it's settings or anything produced the error seen below, the same error I got with my own tilesheet earlier, everything goes white(no transparency) It's like Angband hates files saved from Photoshop:


Settings within Photoshop:


Error after just importing the tileset, saving it then running Angband:

[Blue Baron]

I have sent it. I have also sent a compilation of your tiles that were in TOME beta 28, since it may help and probably can't hurt. In both files I already premultiplied the color and transparency.

Ah, the second Angband tileset was delayed, didn't get it until now. As a result of that, my previous post was about the ToME tileset you sent.

It's as I suspected, the current PNG support code doesn't handle shades of grey but needs a solid border around each object, creature in the tile. I have transparency now with the latest tileset sent to me, but the edges of each object within the tile is sharp like a bmp tile.

But, don't stress with the code, adding these tiles can wait until it's fully functional later on.
