Slope detection?

[TeodorUzumaki (23ky)]

Could someone explain me how can I detect slopes? I thought on doing for example

local result = workspace:Raycast(root.CFrame.UpVector * (-8), root.CFrame.lookVector, Params)

for getting the normal but then I’m stuck and don’t know what to do

What do you need to use the slope detection for?

[TeodorUzumaki (23ky)]

I’m using it for sliding I’ve already got everything but the slope detection and acceleration

I don’t need you to write the code just a quick explanation if you could

Maybe this could help?
rbx documentation on raycasting

A short explanation would be:

Raycasting shoots invisible lines to detect stuff for you.

Yeah i know but to detect the slope angle etc? Dont I need to calculate the surface normal and then something else

[RobloxPlayer_9384 (somerandomperson)]

Sorry, for that I can’t help. I haven’t used Raycasting before tbh

So I wouldn’t know how to detect the angle of the part.

Have you tried searching before posting? It seems there are multiple topics that talks about slope detection.

Detecting velocity against a slope (surface normal)

I’m trying to find the slope of an objects’ movement relative to it’s “forward” face. I’m trying to see how steep the current path is. I’ve tried comparing velocities and relative positions but those have tons of edge cases. I think what I need to do is take the surface normal of the “ground” underneath the object & do some dot product magic using the objects velocity? What would that look like. [image]

Help with slide mechanic, slopes not being detected correctly

For my slide mechanic, I wanted players to have the choice to slide down slopes, but I’ve been having trouble correctly detecting a slope that travels down. My code so far is this: local slope = false local params = RaycastParams.new() params.FilterDescendantsInstances = {workspace.Living} params.FilterType = Enum.RaycastFilterType.Blacklist local dist = 5 local results = workspace:Raycast(root.CFrame.p, -root.CFrame.upVector * dist, params) if results then local normal = results.Normal …

How can I check if a player is on a slope?

Im trying to make a roll mechanic so that a player rolling down a slope can get a speed boost as they go to down if their rolling. But Im not sure how Im supposed to check if their on a slope.

[TeodorUzumaki (23ky)]

Yeah I searched for a lot and checked almost every single topic about this however these 2 you last sent I haven’t seen them so I’ll check them and if I can’t get an answer I’ll come back here.

Marking this as the solution however I didn’t really use this but I finished what I wanted to do.
