I'm curious about this too, also how that game does colliders is curious to me since your katamari can be made up of any object in the stage how the game properly computes collusion without making you proxy jump or just otherwise bug out is interesting to me.

+JamesFLivingstone I think katamari uses a single sphere collision model and scales it depending on how much is stuff is collected.

GANONdork123 that would make sense I guess there's a system in place to detect particularly large objects aswell, like if you have a huge oblong attached to your katamari it makes it harder to roll.

+Kally Wally Whoops! Apologies for that, this is why I shouldn't record audio when tired!

+ClassicGameJunkie Can you do these more often? they're great!

+jontiways I really wish I could, they just take a lot of time to put together! Hopefully I'll have the next one up soon!

+ClassicGameJunkie I can understand that, They're just so damn interesting, just how you break it down, its so damn clear. Totally appreciate all of this. :)

+jontiways Thank you for the kind words!

it may feel dated by today's standards but the voice acting, writing and story is some of the best of the time. This along with the second one and defiance make an amazing story. there are five games but the soul reaver and defiance games are the highlights. they were written by the same woman who wrote for the uncharted games. only these were far darker and not light hearted. it's like a quality in line with both games but complete opposite moods. This is what real vampires are. Lol

yeah the animation technique is nowadays known as morph targeting. it's used for blinking eyes in most modern games

It's not endless, the way games work is by loading the shit that is seen, and not loading what's not seen. Eventually the engine would have run out of calculations and you will hit an end, or crash before that.

There are at least two ways to do this. One way is linewise scrolling, where you have say cloud layers or ground layers that needs to scroll at different speeds - you simply register a line interrupt handler, and in this interrupt handler routine assign the playfield X scoll register to a corresponding value per line or per section from a table that you computed earlier. You will see this in Battletoads and in one place in Kirby near the end of the game, and in MM6 at the Tomahawk stage outdoors. Resetting the XY scroll registers in line interrupt handler is also how all those huge MM6 bosses against black background move. They are much too wide for more or less flicker free sprite graphics, so they are in the background layer. Other way is tiled scrolling, using MMC3 mapper chip or a more powerful mapper chip in the cartridge. The mapper partitions CHR ROM presented to the NES graphics processor, 8K in size, into several smaller sections, and allows to map them each to a location within a much larger physical ROM chip. You part out the smallest page you can, like 1KB, and put the parallax graphics in there, and duplicate them 8 times at different rotations in the ROM chip. So every time you need to shift the tiled parallax section compared to the rest of the background, you just tell the mapper chip to remap the part of the CHR ROM to a new location. It gets a bit complicated at times, but the basic idea is this same one. Also MMC3 and similar mapper tricks are the ONLY way to do large scale background animation, as happens all across Kirby and here and there in MM6, because you simply can't rewrite the tile map nearly quickly enough, as it's on a heavily contended and weirdly synchronised port, so almost every time you try to write there, your CPU simply stops until the write can succeed.

+Tatjana L. As I understand it, the whole world model changes, and its collision goes with it. Both worlds don't exist on the same map - they ARE the same map, the model (and its collisions) just animates to a new shape. There's one puzzle early on where you stand on one end of a scale in the material realm, then switch to the spectral realm and use the other end of the scale as a platform, since objects (i.e. Raziel's body) in the spectral realm can't affect objects in the material realm. Most of the puzzles work like this - do something in the material realm, move somewhere in the spectral realm. And of course, push blocks. Push so. many. blocks.

+Kally Wally Yes this is correct, I would have gone into how the collision works but research never led me to a definitive answer!

+ClassicGameJunkie can see it being tricky and not for runing meshes (holes, disconnected and falling off enemies) and all the "sections" had an animation? and how about more? and so on that could be intressting.
