Download the 4 sprites and 12 scripts of "Ultrafast 3D Raycast…" and open it in Scratch Project Notes
Use the arrow keys to move. Up/Down is forward/backward. Left/Right is turn.
This is a fast raycaster based on the code of my previous one. The rendering time has gone down from 500 seconds to 5 on average! Major changes for more optimization:
- Rendering is wireframe.
- The room is rendered in much larger (and less detailed) chunks
- Better distance coloring
Soon to support:
- Collision detection
- More speed
- 3D sprites
I'm so close to making this realtime speed...I just need some sort of new optimization and I'll be there :D

If you want, check out my project: (link to project) . It's a near real-time visible-map raycasting engine that I'm going to use for a 3d fps. It's going to slow down, though, because of the game
faster
This rpg is cool. Is maya your friend or foe? In this rpg, what does the rick gun do? Please reply.
Him replying? im sorry, but it just that people that are famous NEVER REPLY. (no offense...)
(view all replies)0.808 online
cool
i downloaded it in 1.4, clicked on "edit", then "set single stepping", then "turbo speed", then "start single stepping", and got the rendering time down to 0.1 SECONDS!!!
wow
Wow this is awesome
how does this work? and this wold run alot faster if there were more rendering sprites.
*needs
yes, he need to take out the repeat blocks. I have one that you can't even notice the render time, I can upload it for you.
really good raycasting, but is it possible to make the rendering quicker?
no repeats, I can upload one where you don't even see it rendering if you want...
Awesome!
A long time ago they were doing ariel views.Then they had like 500 costumes but only recently are people starting to make proper zooming rotating 3d games.It´s not long before they have collision.
WTF! i cant even play this so called "racing" game!!!
wow. his is not a racing game. were the !@#% did you get that idea
It's not a racing game, smart one. It's a "Raycasting" engine.
absolutley amazing
NOT cool too slow cause you have to wait
COOOOOOOOOOOOOLLLLLLLLLLLLLL!!!!!!!!!!!!!!
how long does it load?
loading is sssssslllllooooowwww
amazing. slo tho. scratch just isnt designed 2 b fast w/ this kind of computation.
is it even possible to get out??? Not that I don't like it I think it's really cool. I like blackbird1676's idea
I don't get it
u should hide ur varibles and make a sshooter out of this
0.811
AWESOME!
I don't get it
You're definitely on to something.
Um, it is not "ultrafast."
I have an idea! It's be odd, but take out the wall separation! I mean the vertical lines.
0.715!!! YES! YES! YES! You have passed "The JasonFox 3D Test Of Excellence!" I have found the chosen one! Marcus, ready the airship.
man, this is awesome!!!
dude!!!!! how is everyone saying this is so great i love it this is so great its nxt gen what the heck is the point
what the heck
NICE:D
0.809!! But I only have a screenshot of 0.813
pretty cool, by how much do the arrow keys rotate your view?
the lowest i got it down to was: 0.969!!!
The lowest I got was 0.884
(view all replies)i feel like this is randomly rendering different walls...i got lost. but dam, great programming.
For me I only get to see walls :/, but I did get it down to .1 seconds rendering time :)
This is incredible! Keep up the good work!
I think scratch 3d would be amazing and you have gone really far, but I think the next thing to do would be to make real-time rendering, before adding color, greater speeds, collision detection, and stuff like that.
wow... really nice!
cool
This is on the front page, because I told Kerero about it!
ultra fast?! this is kinda slow no ovvence
When he meant ultra fast he meant for a scratch raycaster. Those are usually very slow.
ok, you make something faster.
(view all replies)ovvence? you mean offense
(view all replies)make it in real time it would be SWEET reminds me of those old old old arcade games with the wire frames lol
What do you do? You just sit there and watch lines come up on the screen?
This is neat, that would be awesome if this was in real-time. You could make a game out of this if that happened. I'm gonna see the scripts.
Please make a realtime one! It'd rock!
hmm, i dont think that this could be made into a scratch game. its to slow.
good!!!
where did you get the music from?
Nice shadows. I'm not sure if this is really 3-D or not.
It's confusing, the walls look random, I can't see the overall map.
This is great!
Wow! Amazing!
i wanna make 3d stuff!
Very cool drawings and how do you know so much numbers?
VERY GOOOD . GOOD WORK
Pretty good! I'm going to try to optomize it more.
True 3D.
Cool race tray! The race tray graphics look real 3D looking! :D It looks like a 3D simulation of a construction place when you stand in the area of the construction site. Great race tray! :D :D :D :D
