Hello Developers!
I’ve actually tried coding this on my own, but it did not work. So I decided to ask the community for help.
So there’s a footstep particle script located inside the player’s character. The particle appears when the player walks. But the problem is that I don’t know how to change the particle color depending on the color of the part the player is walking on.
This is the particle script:
--Variable --
local player = game:GetService("Players").LocalPlayer
player.CharacterAdded:Connect(function(char)
local humanoid = char:WaitForChild("Humanoid")
local leftFoot
local rightFoot
-- Rig Check --
if (humanoid.RigType == Enum.HumanoidRigType.R6) then
leftFoot = char:WaitForChild("Left Leg")
rightFoot = char:WaitForChild("Right Leg")
end
--Particle Create --
local particle = workspace.ImportantParticle.ParticleEmitter
--Values --
local On = false
-- Cloning the particle --
local pClone = particle:Clone()
pClone.Parent = leftFoot
local rpClone = particle:Clone()
rpClone.Parent = rightFoot
pClone.Enabled = false
rpClone.Enabled = false
-- Humanoid Movement
while true do
local val = humanoid.MoveDirection
if ((humanoid.FloorMaterial ~= Enum.Material.Air) and (val.X ~= 0 or val.Y ~= 0 or val.Z ~= 0)) then
if (On == false) then
On = true
pClone.Enabled = true
rpClone.Enabled = true
end
else
if (On) then
On = false
if (pClone ~= nil and rpClone ~= nil) then
pClone.Enabled = false
rpClone.Enabled = false
end
end
end
wait()
end
end)
I’m pretty sure your supposed to use raycast, but I’m not really familiar with it.
You would be correct. Raycasting is probably the best option for this.
Example
local origin = leftFoot.Position --Where the ray will begin from
local direction = Vector3.new(0,-1,0) --World Down
local distance = 5 --Studs
local CastParams = RaycastParams.new()
CastParams.FilterType = Enum.RaycastFilterType.Blacklist
CastParams.IgnoreWater = false
CastParams.FilterDescendantsInstances = {myChar} --Put any instance you want to ignore into this table
local castResult = workspace:Raycast(origin, (direction*distance), CastParams) --Perform the raycast
if(castResult)then
local color = castResult.Instance.Color --Get color value of part hit
pClone.Color = ColorSequence.new(color)
rpClone.Color = ColorSequence.new(color)
end
local event = game.ReplicatedStorage.FootstepParticle
event.OnServerEvent:Connect(function(plr)
local char = plr.Character
local humanoid = char:WaitForChild("Humanoid")
local leftFoot
local rightFoot
-- Rig Check --
if (humanoid.RigType == Enum.HumanoidRigType.R6) then
leftFoot = char:WaitForChild("Left Leg")
rightFoot = char:WaitForChild("Right Leg")
end
--Particle Create --
local particle = script.ParticleEmitter
--Values --
local On = false
-- Cloning the particle --
local pClone = particle:Clone()
pClone.Parent = leftFoot
local rpClone = particle:Clone()
rpClone.Parent = rightFoot
pClone.Enabled = false
rpClone.Enabled = false
local direction = Vector3.new(0,-1,0) --World Down
local distance = 5 --Studs
local CastParams = RaycastParams.new()
CastParams.FilterType = Enum.RaycastFilterType.Blacklist
CastParams.IgnoreWater = false
CastParams.FilterDescendantsInstances = {char} --Put any instance you want to ignore into this table
local castResult = workspace:Raycast(leftFoot, (direction*distance), CastParams) --Perform the raycast
if(castResult)then
local color = castResult.Instance.Color --Get color value of part hit
pClone.Color = ColorSequence.new(color)
rpClone.Color = ColorSequence.new(color)
end
-- Humanoid Movement
while true do
local val = humanoid.MoveDirection
if ((humanoid.FloorMaterial ~= Enum.Material.Air) and (val.X ~= 0 or val.Y ~= 0 or val.Z ~= 0)) then
if (On == false) then
On = true
pClone.Enabled = true
rpClone.Enabled = true
end
else
if (On) then
On = false
if (pClone ~= nil and rpClone ~= nil) then
pClone.Enabled = false
rpClone.Enabled = false
end
end
end
task.wait()
end
end)
I’m really sorry if the script is really messy, just had to rush everything.
I see. That’s because its terrain I believe. That makes things more complicated. I’m not entirely sure we can pick up the color from raycasting terrain. But let me do a test or two here and I’ll post back. Might have to keep a record of colors to use for certain materials.
Oh well. I did figure out how to get the material color of the terrain. But if its a part then check the color value set on the part.
Here how to get the material color of the terrain or part:
if(castResult)then
local color
if(castResult.Instance.Name == "Terrain")then
--Get Terrain Material Color
local material = castResult.Material
color = game.Workspace.Terrain:GetMaterialColor(material)
else
--Get Part Color
color = castResult.Instance.Color
end
pClone.Color = ColorSequence.new(color)
rpClone.Color = ColorSequence.new(color)
end
Idk. This should be done on the client side though. Especially since its a client effect and we are using the position of the clients foot.
Make sure you remove the local prefix of the color variable in the terrain color section. That was a mistake, I’ve corrected that in the code I posted.
if(castResult.Instance.Name == "Terrain")then
--Get Terrain Material Color
local material = castResult.Material
--local color = game.Workspace.Terrain:GetMaterialColor(material)
color = game.Workspace.Terrain:GetMaterialColor(material)
else
I think it’s more likely related to your use of the instance method :FireServer() to transmit data to the server. RemoteEvent instances are restricted/limited in the types of values/data they can exchange between the server & the client.
