I modified my 3d engine a bit and divided x, y, and z by w before projecting, and this appeared on my screen. It would be in 3D but my virtual parallax barrier looks horrible in screenshots so I turned it off. There was a lot of extrapolating and pattern recognition involved, since I don't know that much about 4D math.

Oh, I thought that's what you wanted. The width of your sprites is 64, and you can't make a sprite loop its UVs, but if you made 4 sprites, each with a width of 16, that would fix your problem. By the way, you could say "I MOD 16" instead of "I-16*FLOOR(I/16)".

Might want to take your UV coordinates and divide by 4. But I haven't seen your code yet. So I might be wrong.

I just looked at your projection formula, and it seems really weird, especially when DEPTH is set to higher values. Notice the concave face of the cube on the left. I use X'=X/Z*ZOOM Y'=Y/Z*ZOOM Where ZOOM controls perspective distortion. I usually set it to 256.

If you use "IF B AND 4" instead of "IF B==4", then you can press multiple buttons and the IF statements will still trigger.

Yeah, I learned 3D stuff back in Petit Computer. If you need any help, I'd be glad to!

Nice! Great to see another person with knowledge of 3D!

Raytracing would be way too laggy, seeing as it demands the ability to process 240x more rays than raycasting.

I don't know much about raycasting but I think you can fix the fish eye by just narrowing your field of view. Taking all the angles and dividing by a set amount might do the trick.

Experimenting with a virtual parallax barrier. It's animated so that you don't notice the black stripes when it's running, but when it's a single frame, you can clearly see them. Concept stolen from K4KVPRP.

Ok. [TWR] means that TWR is the name of your active project. It's the folder where your programs will save. You can change it by going to "Manage Projects/Files" on the main menu and clicking the "Change Active Project" button.

"Syntax Error" means you did something wrong in your code. I can't help you fix it until I see your code.

Big update to my 3D engine! New features, and comments describing how to use it. Demo code is actually a game now! Key: 83NVK3H4

(LOCATE:1) means that the first parameter of LOCATE is causing the error. Keep in mind that you said DISPLAY 1 right before LOCATE and that means you're on the 40x30 lower screen.

If EGG_EX>39 or EGG_EY>29, it triggers an error because you're asking it to print outside the screen boundaries.

Well, RND has two parameters now. The first one is the seed ID, which is from 0-7, and the second one is the max value.

Thanks! I didn't know about that. DEF is still new to me.

If you get an error at 0:2039 that means program slot 0 and line 2039. Try looking there.
