MovementHandler (Crouch, Sprint, Slide, Prone)

wravager · November 7, 2021, 7:18pm

You really made this guy post an entire License agreement for a simple script

legs_v · November 7, 2021, 7:20pm

This isn’t github, you can give you the code.

ToldFable · November 7, 2021, 10:31pm

The animations might be invisible because you don’t own them. I’m pretty sure it’s a security feature.

@GiantDefender427 try setting these models on sale

https://www.roblox.com/library/7932221054/CrouchWalk
https://www.roblox.com/library/7921074914/Slide

Also, a critique on the code:

Since this runs on the Client side, you can eliminate the Player parameter. Just say Player = game.Players.LocalPlayer since it doesn’t make sense to call this on any other player.

GiantDefender427 · November 7, 2021, 10:33pm

Well those animations aren’t really high quality so i never thought people would want to be using them, but yes I can put it on sale no problem.

GiantDefender427 · November 7, 2021, 10:34pm

I have also included the Key frame sequence if you look inside the animation objects.

ToldFable · November 7, 2021, 10:53pm

oh sorry, i didn’t see that part of your post

LucasMZ_RBX · November 11, 2021, 5:23am

It’s nice to have a LICENSE but realistically no one cares in Roblox development.

I believe if you have your code published to Roblox you’re stuck under specific conditions anyway.

GiantDefender427 · November 11, 2021, 5:27am

Oh no I have 2 topics now what do I do?

GiantDefender427 · November 11, 2021, 7:36am

Update

I got some feedback from professional developers and I think they have a strong point, so I made a few changes. Now you can put the script in StarterPlayerScripts and that’s all, no worries if the character dies, script automatically adjusts.

hypnoticrunner12 · November 24, 2021, 5:08pm

It doesn’t work even though I put my own animation only thing I changed in the script was
States.Crouch and States.Slide to True can you please help me? Is there a way to change Keybinds and how would I configure a prone system in your script?

-- State

local States = {}

States.Sprint = false
States.Crouch = true
States.Slide = true

-- Load Animations

local CrouchIdleAnim = "rbxassetid://8087634282"
local CrouchWalkAnim = "rbxassetid://8087642001"
local SlideAnim = "nil"

Screenshots

GiantDefender427 · November 24, 2021, 5:20pm

You need to change the AnimationId property of the Animation, not the variable.

Doing that will definitely cause errors, and does not seem to be necessary. To change the keybind refer to the BindAction function of ContextActionService, as that is what is used for player input.

Prone system is till not yet confirmed due to quality. In Crouch the camera does not move accordingly, in Slide as well. Till I ensure quality, I won’t be looking forward to Prone.

robloxapp-20211126-1702562.wmv (2.2 MB) Ps: sorry for the “rain” it’s an in-game weather system I was testing

PPlayer31 · November 27, 2021, 2:51pm

I know that this is completely inaccurate to the topic, but your weather system causes strain on the server.
You should add some more particle emitters and cull them according to the players camera. ALL OF THIS SHOULD HAPPEN ON THE CLIENT. In order to clone stuff and put them to the workspace FROM THE CLIENT, simply put the stuff to clone in ReplicatedStorage. I do not intend to ctiticize, I intend to help. Sorry for the irrelevant to the topic disturbance.

GiantDefender427 · November 27, 2021, 4:05pm

PPlayer31, next time please take this to the messages.

PPlayer31 · November 28, 2021, 3:07pm

OH YES I FORGOT! Sorry for that!

Synthlwave · December 9, 2021, 1:12am

Quick question, for the animations would we move the player down or does the script handle that?
And what about the Animation priorities

GiantDefender427 · December 9, 2021, 2:55am

I did not understand what you mean by this…

CivilVivii · December 9, 2021, 3:50pm

He basically means - when making a animation, or the animations for crouching, does the script move the player’s humanoidrootpart/character down automatically, or do we have to manually animate the character down.

GiantDefender427 · December 9, 2021, 5:54pm

No the animation does not move the HumanoidRootPart, and I don’t know the need to move it in the first place… if it is to move the Camera, Humanoid.CameraOffset is what will be used. And if it is about moving the body parts down, yes the Animation does that.

GiantDefender427 · December 10, 2021, 6:14pm

Update

Alright everyone update night(I’m in India so bear with me), today’s changes are:

Animation speed depending on WalkSpeed
Camera moves up and down while Sliding and Crouching

This time the code is also a lot better formatted and placed so hopefully things will be a bit easier to understand, that’s all!!

Make sure to drop your feedback and a like down below

For the one’s who are wondering, I will be adding Prone in the next update, I am trying not to rush things so stay tuned!
