Whay is Raycast()?

Ben 2.0 · 16 Jan 2022, 18:48

I was messing with trying to make a 3D renderer when I tried to create a custom function called raycast(). However it appears this is already a function in FUZE. I can't find anything about it in the help page so I was wondering if anyone has already made a demo.
If you could link the post or give the ID that would be great thanks!

It appears to be undocumented

Oh...
Then why does it turn blue when I type it in the code editor like other functions?

@ben-2-0 I mean it is in the language but it is an experimental feature that may or may not be eventually made official. I will see if I can find out what the parameters are if you want to try it

Parameters are currently a position and direction in the form of a vector. The only output is a very large number that starts with 34. Thanks for looking into it @pianofire.

I can't remember right now if this was officially implemented. It was intended to return a distance value from a 3D intersect. For example, if you wanted to measure the distance from four wheels of a vehicle on a sloped surface you would then be able to rotate the vehicle to match the slope. So the position is the point you want to check from. The vector is a 'ray' cast out in the direction given. The return 'should' be the distance from the point the Ray intersects with another 3D object.

Again however, I can't recall if it was fully implemented so it could do with some testing to be certain.

I was using it in a 2d area so that would be why I got a strange output.

@jonboy Would that be collision with the actual object or with the object's collision box?

watched this a while back, would be great to have this fully implemented

Jonboy · 17 Jan 2022, 14:53

@vinicity Collision box only - at least I think so! (so sorry..)

Just a single ray so far untill I get the distance height scales worked out.
Been trying this for a while, I'v managed to get it fully working using scratch casting 60 rays using distance to control brightness and scaling.

Very cool, if anyone wants to see what I made, let me know.

Show us!
