Looking fairly in depth, into how the eyes in The Legend Of Zelda - Twilight Princess work.
A HUGE thanks to Ben Jones. Without his invaluable research this video would not have been possible!
Check out his fantastic work here:

As a game developer myself, I hope to bring some unique insight into the minds of the developers who made some of my favourite games.

How did Nintendo achieved the Ink in Splatoon to overlap each other without some strange texturebugs? Could be an interesting question.

@Lizzymun 9 жыл бұрын

LumianPrivat or the ink at all. It looks so good

@JusticeJanitor 9 жыл бұрын

LumianPrivat I'm going to take a guess here and in programming terms, surfaces are a type of object. Something like InkedSurface. That surface probably has a color attribute and when something happens that would trigger a color change, that attribute is changed and that change is displayed in the next view refresh. That's just a guess, it could be something completely different.

@DVD892 9 жыл бұрын

JusticeJanitor My guess is that there is an invisible texture above the ground which has 3 values: no ink, ink1 and ink2. Depending on who shoots the ink, it pastes a texture of ink1 or ink2 on the texture and the game colores it at the end. Now that Nintendo said that in the next update a team can have 2 ink-colors it could be with more textures, e.g. ink3 and ink4

@ClassicGameJunkie 9 жыл бұрын

LumianPrivat I've been looking into it, there's a bunch of possible ways they could do it, and I'd rather avoid guesswork that may be wrong. I'm keeping my eyes peeled for more info as I'd love to do an episode on it!

I'd like to see how some of the shaders worked in Mario Galaxy - the specular rim lighting on everything, the water effects (probably not too interesting given that you just covered sunshine) and things like the fur effects on the Queen Bee. Also how they managed to display so many Pikmin on screen (I believe this ties into that wacky Mario 128 story from way back). Or Mode 7 on the Snes! I just keep editing this post with questions...

One aspect of video game art that I have noticed that a lot of lay-people don't seem to fully understand, is the difference between textures and geometry or polygons. I often see people referring to "missing textures" that are actually examples of missing geometry. Most game engines replace textures that are missing with a default texture, usually an image in a gaudy color like pink or purple with noticeable text. That way the missing textures are readily apparent to the developers so that they can fix them.

Most game devs use a similar shape within the characters head for the teeth, right? I'm guessing that based on some of those common "look inside the characters face" bugs from games like Assassins Creed Unity. I wonder if Twilight Princess used a similar 2d style approach to characters teeth, or if the mouth was handled some other way.

here's one that's interesting, in the legend of zelda the minish cap, there are the picori, who (it's a sprite based game) move their heads to follow link around the screen while not moving the body? how did they make the sprites follow objects? Masaeanela is a let'splayer who pointed that detail out in the 2nd episode of her series on it, which made me wonder about it. in fact, how do they make heads track an object in any medium? Also, how do they make a sprite for an object change depending on what it is doing? and how do developers attach hitboxes and hurtboxes to sprites? sorry, I have a lot of questions.

@SP8inc 7 жыл бұрын

Well, about the hitbox, I think it depends on the engine. For example, in Game Maker, a 2d game engine, you can simply assign a hitbox to any given sprite, in different shapes.

@SuperShadow64 7 жыл бұрын

Okay, I have a better handle on how they get the look of the eyes now. A bit more technical, though, how did they get Wind Waker Link's eyes to dynamically follow the action and look at important objects in his field of view? Head tracking in general is pretty difficult for me to conceptualize. I know that when done poorly you get an Exorcist effect, so how is that prevented? Just discovered this series via Extra Frames and I already love it to bits. Cheers uwu

Hey ClassicGameJunkie, I was wondering how Source games use skyboxes. In games like TF2 there are the stages with collision and then the enviroment around them, you can't access the enviroment without noclipping, noclipping into the enviroment causes it to go black, but theres a small spot around the map where the skybox is located in a much smaller form, if a player noclips there and another player on the collisioned area looks at the skybox the player who noclipped to the small section looks much more larger. How does this work? Thanks in advance.

This is a curious question if you think about it. Any game with a save function must be able to read the memory card for that to work, and any game that can trigger the controller rumble can, naturally, do so whenever it wishes. It's likely just a line of code that tells the console when to vibrate, with which motors and for how long. The only unusual thing is the unorthodox way they used these functions, to brilliant effect.

BeatsByRik If you mean file size: More powerful hardware that is able to work alongside more aggressive compression techniques in real time. Heavily compressed data can be inflated quickly in real time as it is required and loaded into RAM for execution. In the past this would have been too computationally intensive. So, more and better textures in less space that you can use more easily. Also many more gpu filtering and lighting effects.

As with most game design solutions, there's more than one right answer, and it's really a question of art direction and optimisation.
