How to control the behavior a collider has when falling on an edge

[fluid otter]

Hello, I’m trying to control the behavior of my capsule collider so that it behaves the way I want when falling on an edge. I’m still not sure how to do what I want which, in the end, on paper, is pretty straightforward :

You know how gravity makes a Rigidbody fall ? And you know how if a Capsule collider is on an edge with the center not touching the ground, it kinda slides off to end up falling ?

Well with regular physics, it will slide faster the further away from the edge the capsule “sphere center” is.

What I want is for it to slide off as quickly as needed so that we keep that 9.81 m/s2 vertical acceleration. Which would give that effect :

Apparently I should hook into the contacts and perform what I want based upon them using Physics.ContactModifyEvent, but I don’t know how to do this.

Can someone please help ?

Thanks !

can i propose an alternative solution?

Yeah sure go ahead so long it does what I need, it’s good 😊

why not just compute the vertical velocity the player should have at every height. like at 20 m above the ground it has n downward velocity or at 10 m above the ground it has n + idk velocity

and if the player doesn't have that velocity, set the y velocity to the velocity it is supposed to have

The gravity calculation is to complex for that plus it takes into account a time scale for time slow down/stop powers. It wouldn’t work that way. Also, how do you jump ? Or anything ? That would bring a million conditions to make that work. Hooking into contacts certainly is the way to go, I’m just not sure what to do

when you fall, is gravity the only thing that can affect your velocity?

for your solution, how will you modify the contact point?

[fluid otter]

No, other actions can affect velocity, and about the contact point, I have no idea, hence my question x)
