As I visit for the first time in almost 7 years, I feel the need to make at least one post so that I'll know how long I was gone when I poke my head back in around 2024. How's everyone doing? Seems a bit quieter around here.

General Discussion / Re: See my algorithm to upscale pixel art

That's a nice algorithm! Does it perform as well on smaller pieces?  There was a paper at this year's SIGGRAPH about this subject:  Some of their results are better than others, and I'd be curious to see how your algorithm compares to theirs. Can you post some of the pictures they used run through your algorithm? I'd be especially curious to see the Yoshi, since that's one they didn't do a very good job at.

Shiny. I was new to Tzigla so I just made an account using my Google login. The merging should be useful for other Tzigla users, though! :y:

I'm not sure how active Tzigla is these days, but Pixelation authentication appears to be broken. The authentication link just takes me to the Pixelation front page.

*pokes head in*

*looks around*

Man, this place really doesn't change, does it? I leave for... *checks recent posts* really? Almost 3 years? Man, time flies. Anyway, I leave for three years and the place still looks pretty much the same as ever. Well, I suppose "ever" is a relative term, since there was more turmoil, server changing, and new skins back in the day... What I'm trying to say is "hi guys, how's it going?"

[EDIT] Also, what's up with all the Guests viewing remarkably random topics? There are two looking at the election results from '05, others viewing (or printing) topics from '07 where most of the picture links are broken, etc. Are these bots? Spammers looking for text for their next opus? Actual people who like reading unusual things? [/EDIT]

General Discussion / Re: Help, Sprite animation for Iphone game.

Firstly, welcome to Pixelation! Sit down, relax, learn some stuff.

Inserting images is straightforward. Just use img tags!
Code: [Select]
[img][/img]The above code will insert the image found at the specified url into the post.

As for how to make sure your sprites look right on the iPhone screen, that's partly a matter of resolution and ppi (pixels per inch). The iPhone 4 has a pretty high ppi, since it packs a 960-by-640-pixel resolution into a 3.5-inch screen: about 330 ppi! Compare that to a computer monitor, which fits (for example) a 1920-by-1080-pixel resolution into a 20-inch screen: only 110 ppi. So a sprite that's 110x110 pixels will be about an inch square on a computer monitor, but only 1/3 of an inch square on the iPhone screen.

All of that is mostly irrelevant, though. When making pixel art, you don't tend to care too much (you have to care some) about the intended resolution. The most important part is that 1 pixel is 1 pixel. So pick a pixel resolution (say, 32x32 or 64x64) and stick with it. It will be smaller on the iPhone screen, but that's okay! Everything is smaller on the iPhone screen :) Make your sprite in the intended resolution and it will look fine on the iPhone screen. Just remember the overall resolution when putting together mockups and comparing your sprite to the whole.

That was all kind of rambly, so I hope it made sense. If you'd like some clarifications, feel free to ask. Let's see some art!

Pixel Art / Re: Animated Bird sprite
« on: December 21, 2011, 05:18:44 pm »
Nice looking bird! I don't really have any critiques on the bird itself, but have several related to the animation.

My biggest critique is on the timing. The down stroke seems to have very little force behind it since the upstroke is just as fast. Also, the body should not rise in phase with the wings. The body should be highest 1-2 frames into the up stroke and lowest 1-2 frames into the down stroke, since momentum will keep it in motion until a sufficient force has been exerted to move it. Also, if you can swing it with your resolution, making the body movement more of a sine wave (faster in the middle, slower/hesitating at the top and bottom) would help.

Also, I'm not sure the tail waggle works for me. It looks much too wobbly. I think a tail wave would work, just not quite that quick.

Quick searching found this animation, in which you can see the force of the downstroke, the timing of the body rise and fall, and a more appropriate tail wave. Obviously your bird is in a much different style, but the timing principles should be applicable.

Overall, good start; I look forward to seeing the next iteration :-)

Holy crap guys, this looks awesome!  Good call giving this one a predefined palette; the last one definitely had the "way too many colors" problem.  Nice work, everyone!

*Throws hands up* I don't know!  I swear!  I was asking the same thing last time I was here!  *Looks around frantically* Why don't you ask one of the mods?  They might know better!

Hey guys.  I somehow managed to wander away from Pixelation for several months; I think school happened >_<  Glad to see you're all still here, unlike last time I was gone for more than a couple weeks.
