FOSS gamedev and creative worlds

I found a string of rainbows underground, but there is no pop-tart cat in sight. That's not normal, is it? The error seems to be repeatable too. I deleted map.sqlite, to force the map generator to try again. The same odd catless rainbow showed up.

The seed is 4666977680476765976, and the rainbow is at (301,-128,206) to (313,-128,206). It's mostly in a wall, if you try to teleport there.

I fiddled with the Lua a little to get the expected location of the cat, but I don't have enough experience with Lua to decipher how the cat generating algorithm actually works, or why it's doing this. The cat should be at (316, -129, 206), with a facing of 3 (not sure what direction that is), and a rainbow length of 14. Since the rainbow is only 12 blocks long, I suspect the cat and the rainbow are being generated, and then the cave is being generated, wiping out the cat and two rainbow blocks. But that's just a theory.

I don't think you should really concern yourself with this, but the nyancat will be around somewhere.

...but there is no pop-tart cat in sight.

POP TART CAT? REALLY I'S "NYAN CAT"

Watch this from start to end. It's really enlightening:

Hmm. I got busy and lost track of this topic. Sorry for the late bump.

If it is around, it is detached from its rainbow. It wasn't on either side. I won't concern myself with it though, like you said. Whether it is a problem or not, I don't have the skills to figure it out. I'll focus on things I CAN fix. Like the bug in the bucket. Speaking of which, I still need to write up my post with the fix ..... I still haven't even posted that the bug exists ....

The creator of the cat named it the poptart cat. As he is its creator, I use his name for it, not the name given to it by someone who paired it with annoying music. Plus, "nya" is the Japanese word for "meow". So basically, people are calling a cat with a breakfast food body a "meow cat". Is "meow" the best description for it? I think not. Plus, "meow cat" is sort of redundant. Sort of like a woof dog, or a ribbit frog.

I don't really care what other people call it, it doesn't bother me, but I'm stubborn, and insist upon calling it by its true name.

I hate to break it to you, but annoying music being looped for ten hours isn't exactly enlightening.

Nyancats generate under -31.

I don't know what's up with that. According to this post (http://minetest.net/forum/viewtopic.php?pid=40202#p40202) a poptart cat spawns at a height of 24. Try it. It's actually there. I'm not sure how the height_max thing works, but it isn't keeping all the poptart cats underground. Just most of them.

The creator calls it poptart cat, but the internets decided to call it nyan cat.

The original creator of the pop tart cat *also* calls it a nyan cat in some of the stuff he sells.

Sorry for the late reply. I somehow missed this when the topic was still active.

He calls it that to make money because that's the name people know it by. He ALSO says that to him, it will always be called poptart cat.

Also, while working on an unrelated project, I found the reason for the catless rainbow. It's a mapgen issue. C++ generates most of the map, then calls the Lua scripts, then goes back to C++ mapgen. The second time in C++, it generates more caves, poking holes in everything. This is why the cat was gone, this is why partial trees show up, and this is why floating plants can be found in deserts.

Bug? I don't know. But at least I understand why the cat is gone.
