Blood Splatter System not working

Help and Feedback Scripting Support
#1

So, I revamped my blood system, and I’m having issues where when a player takes a certain amount of damage blood spills, but now the blood isn’t spilling when the player takes a certain amount of damage. Can anyone help?

I’ve already tried to make it where whenever the humanoids health changes, blood occurs when you take damage but that didn’t work either.

here is the script:

local Module = {}

local RunService = game:GetService("RunService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local TweenService = game:GetService("TweenService")

local BloodAssets = ReplicatedStorage["BloodAssets"]

local BloodSounds = BloodAssets["Sounds"]
local BloodParticles = BloodAssets["Particles"]
local BloodPrints = BloodAssets["BloodPrints"]

Probably not what is going to help you, but try using the RaycastData parameters to Enum.RayCastFilterType.Exclude, hope it helps.

I’m about to try that out, thank you!

#4

Tell me if it helped :smiley: Oh and you could try using task.spawn instead of all of those coroutines, but it’s kind of the same, maybe a bit more optimized! @dd_y09

#5

It didn’t help, but I appreciate you trying. :+1:

#6

Thanks, hope you will find the solution soon!
