CCL quick start

In the Character Controller Library (CCL), traditional character abilities (run, climb, jump, swim, etc.) are easily configurable through scripting. For custom character mechanics such as dashing, aiming, wall‑jumping, and more, see custom abilities.

Enable CCL

The CCL is opt-in through Studio's Avatar Settings window. To enable it:

1. Enable the CCL beta through File ⟩ Beta Features ⟩ AvatarAbilities Character Controller Library.

2. From the Avatar tab, open Avatar Settings.

   

3. Select the Movement tab on the left side of the window and, in the Abilities section, select Character Controller Library.

   

4. All of the standard abilities like Running, Jumping, and Climbing are enabled by default. To disable any of them at runtime, uncheck the associated box.

   It's not recommended to disable Running, as doing so will prevent characters from moving along the ground. Additionally, you should always keep Getting Up enabled if Falling Down is enabled, as a mismatch will allow characters to fall down (trip) but never get back up.

Configuration

Through a script that runs from ServerScriptService, you can experiment with the built‑in ability attributes. You can also modify specific controllers to adjust the physical simulation of the character and its interaction with the environment, such as the character's base movement speed.

Attributes

At runtime, CCL exposes each built-in ability as a Configuration in the character's Abilities folder. This folder usually lives under AbilityManagerActor, but it can live directly under the character in setups without an actor. Use AvatarAbilities.getAbilityConfigurationForCharacter() to access an ability configuration from either setup.

Each ability contains easy-to-configure attributes such as those noted in the table below. Some attributes correspond to legacy Humanoid properties. This relationship identifies equivalent settings, not bidirectional synchronization. The compatibility layer copies changes from these Humanoid properties to the corresponding ability attributes. Jumping attributes initially use the corresponding StarterPlayer character properties.

The abilities in a character's Abilities folder may vary, depending on which abilities you enabled/disabled. Confirm available abilities and their valid attributes before you attempt to configure them via scripting.

To set ability configurations for all characters through a script:

1. Create a new server-side Script within ServerScriptService and rename it to AbilitiesScript.

2. Copy and paste the following code into the new script. This example multiplies the base movement speed for the Running ability by 2. Feel free to adjust other ability attributes such as those described in the table above.

   Script in ServerScriptService

   local Players = game:GetService("Players")
   local AvatarAbilities = require("@rbx/AvatarAbilities")
   
   local function waitForAbilityConfiguration(character, abilityName, timeout)
   	local deadline = time() + timeout
   	while character.Parent and time() < deadline do
   		local ability = AvatarAbilities.getAbilityConfigurationForCharacter(character, abilityName)
   		if ability then
   			return ability
   		end
   		task.wait()
   	end
   	return nil
   end
   
   local function onCharacterAdded(character)
   	local running = waitForAbilityConfiguration(character, "Running", 10)
   	if running then
   		-- Double base movement speed
   		running:SetAttribute("SpeedMultiplier", 2)
   	end
   end
   
   local function onPlayerAdded(player)
   	if player.Character then
   		onCharacterAdded(player.Character)
   	end
   	player.CharacterAdded:Connect(onCharacterAdded)
   end
   
   Players.PlayerAdded:Connect(onPlayerAdded)
   for _, player in Players:GetPlayers() do
   	onPlayerAdded(player)
   end

Controllers

In the CCL, a core ControllerManager instance within the character model, alongside child controllers such as a GroundController, handle the physical simulation of the character and its interaction with the environment. Abilities then interact with the ControllerManager and its descendants to modify controller behaviors or switch between controllers.

Properties for the ControllerManager and its controller descendants are summarized in the tables below, although these tables are not exhaustive; please consult the API classes documentation for additional property options.

To set controller configurations for all characters through a script:

1. Create a new server-side Script within ServerScriptService and rename it to ControllerScript.
2. Copy and paste the following code into the new script. This example increases ground‑based moving/turning speed as well adds a slight acceleration and deceleration time. Feel free to adjust other properties such as those described in the tables above or for each class as documented (ControllerManager; GroundController; AirController; ClimbController; SwimController).

local Players = game:GetService("Players")
local AvatarAbilities = require("@rbx/AvatarAbilities")

local function waitForAbilityConfiguration(character, abilityName, timeout)
	local deadline = time() + timeout
	while character.Parent and time() < deadline do
		local ability = AvatarAbilities.getAbilityConfigurationForCharacter(character, abilityName)
		if ability then
			return ability
		end
		task.wait()
	end
	return nil
end

local function waitForChildOfClass(parent, className, timeout)
	local deadline = time() + timeout
	local child = parent:FindFirstChildOfClass(className)
	while not child and parent.Parent and time() < deadline do
		task.wait()
		child = parent:FindFirstChildOfClass(className)
	end
	return child
end

local function onCharacterAdded(character)
	-- Running provisions the ground controller when it registers
	if not waitForAbilityConfiguration(character, "Running", 10) then
		return
	end

	local controllerManager = waitForChildOfClass(character, "ControllerManager", 10)
	if controllerManager then
		local groundController = waitForChildOfClass(controllerManager, "GroundController", 10)
		if groundController then
			-- Double the move and turn speeds
			groundController.MoveSpeedFactor *= 2
			groundController.TurnSpeedFactor *= 2
			-- Add slight acceleration and deceleration
			groundController.AccelerationTime = 0.2
			groundController.DecelerationTime = 0.4
		end
	end
end

local function onPlayerAdded(player)
	if player.Character then
		onCharacterAdded(player.Character)
	end
	player.CharacterAdded:Connect(onCharacterAdded)
end

Players.PlayerAdded:Connect(onPlayerAdded)
for _, player in Players:GetPlayers() do
	onPlayerAdded(player)
end
