Hello developers!

I’ve decided to rewrite a blood system created by @R0mAAn1CH for personal preference. Anyway, I’ve simply want the blood to stick to walls but don’t know how to do so.

local BloodModule = {}

BloodModule.CreateBlood = function(BAmount,Pos)
	
	for i=1,  BAmount do
		local BloodDrip = script.BloodDrip:Clone()
		game:GetService("Debris"):AddItem(BloodDrip,5)
		BloodDrip.Position = Pos.Position
		BloodDrip.Velocity = Vector3.new(math.random(-40, 40), math.random(0, 75), math.random(-40, 40))
		BloodDrip.Parent = workspace.Debris
		
		local DetectHit = coroutine.create(function()
			local OnHit = false
			
			game:GetService("RunService").RenderStepped:Connect(function()
				if not OnHit then
					local raycastParams = RaycastParams.new()
					raycastParams.FilterDescendantsInstances = {workspace.Debris, BloodDrip, Pos.Parent}
					raycastParams.FilterType = Enum.RaycastFilterType.Exclude

					local raycastResult = workspace:Raycast(BloodDrip.Position,Vector3.new(0, -1, 0),raycastParams)
					if raycastResult then
						if raycastResult.Instance.Anchored == true and raycastResult.Instance.CanCollide == true then
							OnHit = true
							local BloodPuddle = script.BloodSplatter:Clone()
							game:GetService("Debris"):AddItem(BloodPuddle,5)
							BloodPuddle.Position = raycastResult.Position
							BloodPuddle.Parent = workspace.Debris
							
							--//Tween
							local TweenGoal = {Size = Vector3.new(math.random(-10,50)/10,  0, math.random(-10,50)/10)}
							local Tweeninfo = TweenInfo.new(
								1,
								Enum.EasingStyle.Sine,
								Enum.EasingDirection.Out
							)
							local Tween = game:GetService("TweenService"):Create(BloodPuddle,Tweeninfo,TweenGoal):Play()

							BloodDrip:Destroy()
						end
					end
				end
			end)
		end)
		coroutine.resume(DetectHit)
		
		task.wait()
	end
	
end

return BloodModule

Anchor 'em.

Character Limit WOW!

There you go, i will rewrite it myself LOL. Let me know if it works as intended, didn’t test it, just wrote.

local BloodModule = {}

BloodModule.CreateBlood = function(BAmount,Pos)
	
	for i=1,  BAmount do
		local BloodDrip = script.BloodDrip:Clone()
		game:GetService("Debris"):AddItem(BloodDrip,5)
		BloodDrip.Position = Pos.Position
		BloodDrip.Velocity = Vector3.new(math.random(-40, 40), math.random(0, 75), math.random(-40, 40))
		BloodDrip.Parent = workspace.Debris
		
		local DetectHit = coroutine.create(function()
			local OnHit = false
			
			game:GetService("RunService").RenderStepped:Connect(function()
				if not OnHit then
					local raycastParams = RaycastParams.new()
					raycastParams.FilterDescendantsInstances = {workspace.Debris, BloodDrip, Pos.Parent}
					raycastParams.FilterType = Enum.RaycastFilterType.Exclude

					local raycastResult = workspace:Raycast(BloodDrip.Position,BloodDrip.AssemblyLinearVelocity.Unit,raycastParams)
					if raycastResult then
						if raycastResult.Instance.Anchored == true and raycastResult.Instance.CanCollide == true then
							OnHit = true
							local BloodPuddle = script.BloodSplatter:Clone()
							game:GetService("Debris"):AddItem(BloodPuddle,5)
							BloodPuddle.CFrame = CFrame.new(raycastResult.Position, raycastResult.Position+raycastResult.Normal)
							BloodPuddle.Parent = workspace.Debris
							
							--//Tween
							local TweenGoal = {Size = Vector3.new(math.random(-10,50)/10,  math.random(-10,50)/10, 0)}
							local Tweeninfo = TweenInfo.new(
								1,
								Enum.EasingStyle.Sine,
								Enum.EasingDirection.Out
							)
							local Tween = game:GetService("TweenService"):Create(BloodPuddle,Tweeninfo,TweenGoal):Play()

							BloodDrip:Destroy()
						end
					end
				end
			end)
		end)
		coroutine.resume(DetectHit)
		
		task.wait()
	end
	
end

return BloodModule
