New Bunny Hoppy Movement Code

SnarlyZoo · January 11, 2024, 7:34pm

In the AirMove() function change this block of code from this:

local wishSpeed = wishDir.Magnitude

wishSpeed *= moveSpeed

if wishDir ~= Vector3.new(0, 0, 0) then
	wishDir = wishDir.Unit
end

To this:

if wishDir ~= Vector3.new(0, 0, 0) then
	wishDir = wishDir.Unit
end

local wishSpeed = moveSpeed

We can just set wishSpeed to moveSpeed now because wishDir.Magnitude will always be 1 when the wishDir is a unit vector.

Hi,

Can the model be updated with the latest code?

Thanks

coo1ifyy · January 12, 2024, 12:57am

One last question,

Is the default values accurate to CS:GO? Just wondering, if not I’ll play with the values. I asked this since in order to gain a slight bit more of speed you just have to hold either A or D and look the direction and you gain around 1-2 units of speed.

SnarlyZoo · January 12, 2024, 7:02pm

No I just messed with the values until it was to my liking. I’ll be honest I’m not very good with vector math so I don’t even really know what changing each value does lol.

However I would not set sideStrafeSpeed greater than 1 otherwise you can easily gain speed super fast.

1Hate_M0nKEYZ · January 12, 2024, 7:07pm

The animation is surprisingly great, reminds me of CS GO, good job👍

I noticed something while playing with this. It bugged me quite a bit, even though it was such a small thing that it took me a while to realize it was happening.

here’s the problem:

here’s a fixed version:

and here’s a side-by-side of the two:

for anyone wondering how to fix this here is the solution I used in the video above:

	local camY, camX, camZ = camera.CFrame:ToOrientation()
	local cameraCFrame = CFrame.new(camera.CFrame.p) * CFrame.Angles(0, camX, 0)
	local inputVel = Vector3.new(sideMove, 0, forwardMove)

	local wishDir = cameraCFrame:VectorToWorldSpace(inputVel)
	wishDir = Vector3.new(wishDir.X, 0, wishDir.Z)

you just apply this in the groundMove function and the airMove function and it should fix that problem.

Here’s the full default code but with the fix:

local ContextActionService = game:GetService("ContextActionService")
local RunService = game:GetService("RunService")

local player = game:GetService("Players").LocalPlayer
local camera = workspace.CurrentCamera

	groundCheck.Parent = character
	
end)

Vergoblis · January 30, 2024, 4:24pm

Is there any way to make the movement code work with external forces?
Like, for example: If you’re rocket jumping then you don’t keep any of the acceleration from the blast and slow down mid-air, is there a way to be able to boost off the rocket jump?

smoothmove138 · February 16, 2024, 6:33pm

I added this for game controller support. i could not figure out mobile support though. I just use default humanoid movement for mobile in my game

local function onMoveThumbstick(_, _, inputObject)
	local x = math.round(inputObject.Position.X)
	local y = math.round(inputObject.Position.Y)
	
	-- no left or right
	if x == 0 then
		onLeft("actionname", Enum.UserInputState.End)
		onRight("actionname", Enum.UserInputState.End)
	else
		-- right
		if x == 1 then
			onRight("actionname", Enum.UserInputState.Begin)
			onLeft("actionname", Enum.UserInputState.End)
		end
		--left
		if x == -1 then
			onLeft("actionname", Enum.UserInputState.Begin)
			onRight("actionname", Enum.UserInputState.End)
		end
	end

	-- no up or down
	if y == 0 then
		onUp("actionname", Enum.UserInputState.End)
		onDown("actionname", Enum.UserInputState.End)
	else
		--up
		if y == 1 then
			onUp("actionname", Enum.UserInputState.Begin)
			onDown("actionname", Enum.UserInputState.End)
		end
		--down
		if y == -1 then
			onDown("actionname", Enum.UserInputState.Begin)
			onUp("actionname", Enum.UserInputState.End)
		end
	end

smoothmove138 · February 16, 2024, 6:40pm

@SnarlyZoo Thank you for posting this movement script, i love it in my game

SnarlyZoo · February 16, 2024, 7:12pm

Yo thats sick, if you wanted to use the default PlayerModule controls you probably could so that way you could have all the different default Roblox input stuff. I always like making my own input code instead of using Roblox’s but I am pretty sure there is some sort of method called GetMoveVector() or something either in PlayerModule or PlayerModule:GetControls().

coo1ifyy · April 13, 2024, 7:36pm

I don’t like how you can easily be fast by simply holding D and W, how do I fix that?

SnarlyZoo · April 14, 2024, 12:08am

In the function AirMove() always apply friction. So change it from this:

if forwardMove ~= 0 then
	ApplyFriction(1, true)
end

to this:

ApplyFriction(1, true)

coo1ifyy · April 14, 2024, 1:24am

This keeps the bhopping functionality right?

Cause, when I played around with this, I couldn’t find any solutions to even fix this.

YourForgottenPast · April 15, 2024, 3:11pm

Btw I found a really helpful video on this on youtube

SnarlyZoo · April 15, 2024, 7:34pm

Yeah I would honestly follow his tutorial than use my code.

I made this script a while ago, and there’s a lot of things I would change, so I might remake it sometime.

dallasparade · May 26, 2024, 11:13am

the crouch and sprint options are missing, are they supposed to be? i’m very confused (i don’t script)

In the video its just bhoping without crouch jumps

ik this is a pretty old post but its the only one that looks promising… the camera isnt moving and in its “default” position???

ironoshea · December 18, 2024, 8:13pm

I have the exact same error, however, when I play in Studio it doesn’t affect anything, yet my Character cannot move when playtesting in an actual roblox game.
