Im trying to make sonic inspired slope momentum, like in this game I found called “Roly Boi Playground” and adjusting player tilt to slopes, but im not sure how I have tried but im new to scripting kinda and need some help making this for regular momentum heres what i have so far.
local accelerateRate = 10
local decelerateRate = 500
local max = 100
local min = 16
local plr = game.Players.LocalPlayer
local chr = plr.Character or plr.CharacterAdded:Wait()
local rootpart = chr:WaitForChild("HumanoidRootPart")
local humanoid = chr:WaitForChild("Humanoid")
humanoid.MaxSlopeAngle = min
humanoid.WalkSpeed = min
local lastPosition = rootpart.Position
game:GetService("RunService").Heartbeat:Connect(function(dt)
if humanoid.MoveDirection ~= Vector3.new() then
humanoid.WalkSpeed += dt * accelerateRate
humanoid.MaxSlopeAngle += dt * accelerateRate
else
humanoid.WalkSpeed -= dt * decelerateRate
humanoid.MaxSlopeAngle -= dt * decelerateRate
end
lastPosition = rootpart.Position
humanoid.WalkSpeed = math.clamp(humanoid.WalkSpeed, min, max)
end)
I have TRIED EgoMoose wallstick but I do not know how to make it momentum based any help is appreciated!
I’m looking to create a system where the player can reach a maximum speed of 75 on flat ground, but can exceed that speed when going down slopes. Right now, the code limits acceleration to that 75 speed and doesn’t take advantage of the additional speed from downhill movement. Feel free to tweak the code as needed; I’m open to any improvements! also reply if this doesn’t make sense I don’t want to come off rude
Currently your code also controls the slope that the player can walk up. Is this also something you’re looking for?
Is controlling just the WalkSpeed fine?
If so, you can just do a downwards raycast, then you can get the angle of the ground below using:
local function projectOntoPlane(v, planeVec1, planeVec2)
-- Compute the normal of the plane
local normal = planeVec1:Cross(planeVec2).Unit
-- Compute the projection of v onto the normal
local projOntoNormal = normal * v:Dot(normal)
-- Compute the projection onto the plane
return v - projOntoNormal
end
local function getSlopeAngle(raycastNormal, moveDirection)
local up = Vector3.new(0, 1, 0)
moveDirectionRelativeSlope = projectOntoPlane(raycastNormal, moveDirection, up).Unit
return math.acos(moveDirectionRelativeSlope:Dot(up))
end
then change your max walk speed to be 75 + [some function of the slope angle] and use your acceleration code above.
I don’t know too much about ray casts because my small pea brain can comprehend them, BUT I’m going to start reading the article to understand more so I can tell if something doesn’t count as a solution. You are a natural thank you also, where do I implement this in my other script
Raycasts send a probe in a line from a starting position in a direction (the direction is equal to the final position minus the starting position). It detects the first surface in the way of the “ray” that it sends out.
You would do a raycast starting at the HRP down maybe 3 studs.
You would calculate the slope in the Heartbeat connection and use it to max out your WalkSpeed (e.g. maxWalkSpeed = 75 + math.deg(slopeAngleFromFunction) / 90 * 50 -- gets a value of 75 for flat ground and 75 + 50 for vertical ground and etc).
