Hello developers :smiley:
I’ve been trying to develop a realistic goalkeeper using IK, BodyVelocity and AlignOrientation. (Ragdoll as well)

The problem emerges when I use ragdoll when the GK is diving.
Here is a video

The results of the radgoll are not I was looking for. I’m looking for the ragdoll follows the dive and the orientation don’t change so much like in real life or in videogames.
This is an example of I want:


The ragdoll’s script (it’s a module script) for the GK is this:

local module = {}
local PhysicsService = game:GetService("PhysicsService")

local function getNearestPlayer( position )
	local Players = game.Players:GetChildren();
	local dist = math.huge;
	local ret = nil;
	for i=1,#Players do
		local Player = Players[i];
		local Character = Player.Character;
		if ( Character ~= nil ) then
			local Root = Character:FindFirstChild("HumanoidRootPart");
			if ( Root ~= nil ) then
				local t = (position - Root.Position).magnitude;
				if ( t < dist ) then
					dist = t;
					ret = Player;
				end
			end
		end
	end

	return ret;
end

local RootLimbData = {
	{
		["WeldTo"]			= "LowerTorso",

I’ve tried to modify the alignOrientation (Didn’t work) and I was thinking in a solution but my mind is clear rn.

If you have any suggestions or ideas, it’ll be greatly appreciated! :smirk_cat:
Thanks for reading!

#2

function module:activate(Char)
print(“Ragdolling”)
local Character = Char
local Humanoid = Character:FindFirstChild(“Humanoid”)
local HumanoidRoot = Character:FindFirstChild(“HumanoidRootPart”)
if HumanoidRoot == nil then
print(“Cannot create ragdoll: HumanoidRootPart not found”)
return
end
local Position = HumanoidRoot.Position

-- Disable ragdolling during certain actions (e.g., diving)
if IsGoalkeeperDiving() then
    print("Goalkeeper is diving, skipping ragdoll activation")
    return
end

-- Ragdoll activation code
-- Your existing ragdoll activation code here...

end

– Function to check if the goalkeeper is currently diving
function IsGoalkeeperDiving()
– Insert your logic to determine if the goalkeeper is diving
– For example, check if the goalkeeper is in a specific animation state
return false – Return true if the goalkeeper is diving, false otherwise
end

#3

Thank you for your suggestion! I appreciate your help. However, my goal is not to disable the ragdoll during the dive but to make the ragdoll follow the dive motion more realistically.

Specifically, I want the ragdoll to retain the diving orientation and position without drastically changing when the ragdoll activates. In real life or video games, when a goalkeeper dives, their body follows the motion fluidly even when they lose control. I’m looking for a way to achieve that smooth transition. :cat:
