My dashing script is not working even after i tried raycasting, what do i do now?

Asked 88 views1 answers

So, i recently started making the combat system for my game. First thing i made was the "dashing system" (not really dashing, but the idea behind it is that every time the player presses E, they teleport a few studs forward with any NPCs that are infront of them before the teleport get knocked up and stunned)

Well, first problem i ran into was that the player can teleport not only through walls, but if they are too chonky, they can teleport inside them.

Someone recommended that i use raycasting, which i learned and used in the script below, which of course, still has problems

local UIS = game:GetService("UserInputService")
local player = game.Players.LocalPlayer

local deb = false

player.CharacterAdded:Connect(function(char)
	
	local char = player.Character
	local Hum = char:WaitForChild("Humanoid")
	local HRP = char:WaitForChild("HumanoidRootPart")
	
	UIS.InputBegan:Connect(function(input, gpe)

		if gpe then return end
		
		local RayPos = HRP.Position
		local RayDirection = HRP.CFrame.LookVector * 50
		local RayParams = RaycastParams.new()
		RayParams.FilterDescendantsInstances = {
			
			game.Workspace["Drooling Zombie"],
			game.Workspace.Baseplate
			
		}
		
		RayParams.FilterType = Enum.RaycastFilterType.Blacklist
		RayParams.IgnoreWater = true
		
		if input.KeyCode == Enum.KeyCode.E and deb == false then
			
			local ray = workspace:Raycast(RayPos, RayDirection, RayParams)
			
			if ray then
				local collision = ray.Position
				
				if collision then
					deb = true

					Hum.WalkSpeed = 0
					Hum.JumpPower = 0
					HRP.Anchored = true

					task.wait(1)

					HRP.Position = collision

					task.wait(0.25)

					Hum.WalkSpeed = 16
					Hum.JumpPower = 50
					HRP.Anchored = false

					deb = false					
				elseif not collision then
					deb = true

					Hum.WalkSpeed = 0
					Hum.JumpPower = 0
					HRP.Anchored = true

					task.wait(1)

					HRP.CFrame = HRP.CFrame + (HRP.CFrame.LookVector * 50)

					task.wait(0.25)

					Hum.WalkSpeed = 16
					Hum.JumpPower = 50
					HRP.Anchored = false

					deb = false
				end
			end			
		end
	end)
end)

Well, the problem with it is that there are no errors, but, when the ray has collision the HumanoidRootPart gets teleported and it makes the camera all janky because it leaves the rest of the player behind.

Also, even if there are no errors, if the ray has no collision, then the script flat out does not run, at all, even if i have an Elseif statement inside that clearly states that "if there's no collision just do this"

I really need help with this one homies. I appreciate any of it.

You're not checking collision at all, you're just checking if ray.Position exists, which it does. To check if the intersection has collision, you get the part the ray intersected at and check its collision by checking if the CanCollide property is true or false.

To avoid HumanoidRootPart leaving the rest of the limbs, use PivotTo().

local UIS = game:GetService("UserInputService")
local player = game.Players.LocalPlayer

local deb = false

UIS.InputBegan:Connect(function(input, gpe)
	if gpe then return end

        if input.KeyCode == Enum.KeyCode.E and deb == false then
		local char = player.Character
		if not char or not char.Parent then
			char = player.CharacterAdded:Wait()
		end
		
		local Hum = char:WaitForChild("Humanoid")
		local HRP = char:WaitForChild("HumanoidRootPart")
		
		local RayPos = HRP.Position
		local RayDirection = char:GetPivot().LookVector * 50
		local RayParams = RaycastParams.new()
		RayParams.FilterDescendantsInstances = {
			workspace:WaitForChild("Drooling Zombie"),
			workspace:WaitForChild("Baseplate")
		}
		
		RayParams.FilterType = Enum.RaycastFilterType.Blacklist
		RayParams.IgnoreWater = true
		
		local ray = workspace:Raycast(RayPos, RayDirection, RayParams)
		if ray then -- if `ray` intersected at a part (if not, will return nil)
			local hit = ray.Instance
			local pos = ray.Position
			
			if hit.CanCollide then -- if `hit` is collidable
				deb = true
				
				Hum.WalkSpeed = 0
				Hum.JumpPower = 0
				HRP.Anchored = true
				
				task.wait(1)
				char:PivotTo(CFrame.new(pos))
				
				task.wait(0.25)
				Hum.WalkSpeed = 16
				Hum.JumpPower = 50
				HRP.Anchored = false
				
				deb = false
				return -- stops the entire function, preventing the rest of the code to run
			end       
		end
		-- this part of the code will run if `ray` didn't intersect at any part (nil), or if `hit` is non collidable
		deb = true
		
		Hum.WalkSpeed = 0
  		Hum.JumpPower = 0
 		HRP.Anchored = true
		
		task.wait(1)
		char:PivotTo(char:GetPivot() + RayDirection)

		task.wait(0.25)
		Hum.WalkSpeed = 16
		Hum.JumpPower = 50
		HRP.Anchored = false
		
		deb = false
	end
end)

Thank you, it worked. Man i feel like an idiot now, but either way, this was really helpful. I appreciate it
