Alternatives to Humanoid.FloorMaterial?

Help and Feedback Scripting Support
#1

I’ve come across this problem where whenever I hold down the space bar to make the player jump, the FloorMaterial remains nil even after hitting the ground and jumping again. I use the Humanoid.FloorMaterial property for my double jump and it solely relies on the FloorMaterial property to make the double jump happen. Thus, my double jump doesn’t work and it looks like this:

As you can see in the video, the FloorMaterial property doesn’t properly detect the material of the baseplate and leaves it nil or Enum.Material.Air. I will provide my double jump script if that may help solve the problem.

Have you considered raycasting?

local function Get_Floor_Material()
local ray = Ray.new(char.HumanoidRootPart.Position, Vector3.new(0, -5, 0))
local hit = workspace:FindPartOnRayWithIgnoreList(ray, {char})

if hit then
print(hit.Material)
end
end

I’ll consider using this (30 characters)

#5

The ray works, but not on edges. Any way to fix this?

#6

You could cast 4 rays from each edge of the character.

#7

WorldModel:FindPartOnRay() returns the BasePart or terrain cell hit, the point of intersection, the surface normal at the point of intersection, and the associated Material hit.

local Height = (0.5 * RootPart.Size.Y) + Humanoid.HipHeight
local ray = Ray.new(RootPart.Position, Vector3.new(0, -1, 0) * (Height + .1))
local Hit, Point, Normal, Material = workspace:FindPartOnRay(ray, Character)

if Material then
print(Material) -- enum
end

I am not sure if you can get the Material using Hit.Material if Hit is a terrain cell, so much rather use the Material which :FindPartOnRay() returns.

Also, the distance between the RootPart and the ground won’t always be covered by casting a ray downwards 5 studs as different rigs will have different heights.
