Sliding

[woven raft]

How can I achieve a realistic slide like the one shown below.
I want the player to have an initial boost and build momentum as the go down the slope. I also would like the player to align with the slope.

How would I go about this?

vectorforce for momentum and speed
and raycasting and using the normal for alignign the player

one way u can do the slope speed up thing is check for a change in the character's Y. if that Y change is negative and ur on the floor u should gain speed,

how would I go about using raycast normals for player alignment?

[compact tiger]

i personally used a linearforce for when i did it since vectorforce i believe applies an impulse every frame? so the momentum would go up rather than down

[compact tiger]

you can use an alignorientation and use the raycast normal with cframe.frommatrix(

make sure ur aligning the rootpart, not the torso tho

i havent really used normals all that much, maybe something with alignOrientation like gamingNoob said

https://create.roblox.com/docs/reference/engine/classes/LinearVelocity so I should use this

oh ok

you could prolly search “how to align player with raycast normal” and find something on the devforum

also u probs shouldn't check if it's negative u really should be subtracting the speed from however ur handling the speed (so if the y change is negative and you subtract it, it's the same as adding to the speed but if the y change is positive and ur subtracting it then that works)

i remember seeing a video guide on how to make something similar

[compact tiger]

that's what i did but it can lead to some weird fling bugs so be careful with it

[woven raft]

oh ok

[compact tiger]

what i did to counter that is i checked if ur about to hit a wall with a raycast

[compact tiger]

lemme go try to find that video guide i mentioned

[uncut yacht]

wdym momentum goes up

[compact tiger]

like if u apply an impulse every frame, ur speed would go up since ur gaining more speed and ur character doesn't have time to slow down so ur momentum goes up

i think that's how it works idk tho

[uncut yacht]

oh wth thats weird ill test it out

[compact tiger]

i remember a while ago i tried to make a slide using vectorforce and i noticed that when i would slow down the force, it would slow u down very quickly
like u would start sliding, stay at max speed for a bit, and then within around 1-2 seconds you would insta slow down to minimum speed it was weird

Thank you so much
