anyways I just wanted to converted to scratch blocks

object version

if <((Point Z) - (Camera Z)) <[1]> then 
hide
else
set [depth mult v] to ( (FOV) / ( (Point Z) - (Camera Z) )
set [Draw X v] to (( (Point X) - (Camera X)) * (depth mult))
set [Draw Y v] to (( (Point Y) - (Camera Y)) * (depth mult))
set size to ([100] / (depth mult))
go to x: (Draw X) y: (Draw Y) // Add this to actually move the sprite!
show
end

pen version

define draw to x:(x) y:(y) z:(z) // Pass point coordinates as inputs
if <((z) - (Camera Z)) < [1]> then
// Do nothing (don't draw if behind camera)
else
set [depth_mult v] to ((FOV) / ((z) - (Camera Z)))
set [Draw X v] to (((x) - (Camera X)) * (depth_mult))
set [Draw Y v] to (((y) - (Camera Y)) * (depth_mult))
go to x: (Draw X) y: (Draw Y)
set pen size to (depth_mult)
pen down // Or use "stamp" if you want to draw a dot
pen up
end

What is this?

One day, I'll make a 3D Raytraced Platformer on scratch. Maybe.

true, cuz IM MAKING CSV CODER WHICH IS 2D/3D engine
bro is trying to one-up Gl00B now ggs guys we're cooked the war of the

well its 2D/3D so why not? Glue3D doesn't have 2D so I think it's a good thing.

because 2d games are already very easy to make in scratch

some 3D minecraft games are made with raycasting in scratch. but the original one we played is created with 3D projection

That would be so hard bro idk why anyone would do that

since some people can do that like 2.5D 3D or 4D

of the 3d engines? watch voxelbear's newest video to see another 3d engine
I didn't know voxelbear made a 3d engine!!!

it was not from voxelbear

actually, the projection formula is just

go to x: x/w y: y/w z: z/w
go to x: x/z y: y/z

ive actually made one before

I thought he meant 3d engine where you make stuff in it I found out it's actually a platformer

I would like to show you some info about CSV Closer but SCRATCH DIDNT LET ME POST THIS ALL BECAUSE I SAID 5.13D
