Unity hoverboard in 10 steps (short tutorial)

I tried to explain how to make a hoverboard in Unity in 10 steps. For the physics material 'friction combine' setting, instead of 'minimum' you need to use multiply to make it frictionless.

[@matt10y27]

What the heck this is actually a really elegant solution.

[@carterearles9528]

Your videos are the best. They’re short, simple, and in the end you understand everything cause all the code is yours. Keep it up man!

[@spliter88]

I always have trouble with that last step

[@Raul-pg1pf]

[@ryan.j113]

Pshh nah it's like sooo easy
First you gotta... uhh... Y'know... Ummm

Codeer be the one to save me with all these innovative elegant solutions thank you for sharing

[@jishanahamed8592]

Surely the kind of tutorial needed as well as deserved!!!
Keep up the good work!

[@rishabh999100]

We need more man. I remember seeing this on Twitter. Keep it up 👍

[@NapeTheGreat]

How the absolute heck do you not have more subs??? I’m definitely going to attempt this (probably as a vehicle instead of a hover board)
Great video! I love this style of tutorials!

[@jelmervdbij1672]

man this is some top tier content, keep it up!!!

[@bernardo5733]

Adding an inclination to the hooverboard when one side is higher in relation to the ground could be a good idea. That little drift which happens casually in movies when spaceships turn when being chased. Although, nice work, your game it's getting really interesting.

[@generichuman_]

I would also suggest finding the lateral component of velocity (side to side) and adding a force to counteract this a bit, so you don't slide sideways as much. This also allows you to reduce the drag quite a bit while still retaining control when turning. And adding a slight roll torque to the board when turning adds some realism.

[@ERBaruin]

This is so cool man. Good work!

[@artemiyzubarev7068]

Last step: add a game to your hoverboard.

[@croissantsa]

this is amazing

[@timothygooding9544]

great thing about this is that it can be used for multiple things, I'll see if it works for a boat

[@arnaudrousseau2608]

Hi, I love your work! How did you attach th player to the hover board? I can't have a good look with a transform.parent ...

[@eruphin3601]

I wonder if it's mostly the same and possibly even having lesser steps if it's just a literal board that stays on the ground but can still move the same

[@HigaroVeloso]

These lines you use, do you draw them by script or is it a feature of the unity debug?

[@Zotelio]

Hi man, i've followed your tuto, but my board side flip when is floating over a sphere.
I've not understand well how to add force at position, how do you calculate the force to apply it ?

[@blaccy5991]

to add force at position just use rigidbody.AddForceAtPosition();

[@jmas2593]

@@blaccy5991 what do we put in the parameters

[@blaccy5991]

You could up the mass, drag and angular drag buuttt.....
you could also follow these steps:
1. Make a hoverboard script
2. Make a vector3 array
Vector3[] Points;
3. Make a function called Balance where you raycast down from your points and apply forces at the points
Example:
for (int i = 0; i < points.length; i++)
float amount = // distance between points[i] and raycastHit
rb.addForceAtPosition(points[i], vector3.up * mathf.abs(amount));
4. Add damping based on height of point - desired height using the code I wrote before.
5. Up the mass, drag and angular drag 😁

[@anytech1876]

I am noob in noob in unity so can you just paste the whole script here😭

[@generichuman_]

For the force, use a raycast that travels the distance you want the board to hover above the ground (desiredHeight). Then use Mathf.Pow((desiredHeight - hit.distance), 2) * someConstant. The power factor just gives the force an inverse square feel which is more realistic for a force field, and the constant is a scaling factor you can tweak until the hover seems right. I would also use ForceMode.Acceleration for adding forces, so it isn't dependant on the rigidbody mass.
It also helps to add a transform below the hoverboard and set this as the boards center of mass (rigidbody property). This will lower it's center of gravity.

[@coprguy58]

just a lil question : how do we raycast just tell me how or the code so i could understand cuz I use visual scripting (in 2021 version)

[@takumifujiwara2073]

how do you change the height at which it hovers?

[@TheEarlyAstrotype1024]

Someday I will create a wipeout like game

[@jixs4v]

Or you could just cheese it and animate the collider and position through code

[@TheEarlyAstrotype1024]

What if the raycast points are in the front, back, left and right. In the edges instead of corners?
Also what if you put 9 raycast points? Let's say the 4 raycast points in the corners are shorter and the other 5 raycast points (front, back, left, right and center) are longer.

[@raphaelguionaud7839]

The more raycast points you have the more accurately you will be sampling the height of the terrain, so in theory it can only make the movement of the hoverboard look more realistic. However if performance is an issue a small number like 4 should probably be enough. Another consideration is how much is the terrain actually varying? If the terrain is mostly smooth and only changed height gradually you won’t get that much of an advantage by sampling the terrain lots and lots of times compared to only a few times.

[@TheEarlyAstrotype1024]

@@raphaelguionaud7839 Thanks for telling me about this. I was thinking about the hover physics for anti-gravity racing ships like Wipeout Omega Collection. I also wanted it to work on really rough terrains, racetrack borders and racetrack edges that don't have borders. This is when I thought putting four raycast points on the corners might not be good for the hover physics I want. Game physics can affect the gameplay a lot, so I have to be considerate about it.
Just thinking about these things in game development really interests and amazes me a lot.
