"Write a system for a Euphoria movement system"

Creating a Euphoria movement system from scratch would be quite complex and beyond the scope of a simple script example. However, I can provide you with a basic idea of how to approach creating a custom character movement system in Roblox.

1. Create a new folder in ServerScriptService and name it "EuphoriaSystem".
2. Inside the EuphoriaSystem folder, create a new ModuleScript and name it "EuphoriaModule".
3. In the EuphoriaModule script, you can start by writing functions for different character movements, such as walking, jumping, and crouching. You can use the Humanoid object and its properties (WalkSpeed, JumpPower, etc.) to control the character's movement.

Here's a basic example of how you can start writing the EuphoriaModule script:

```lua
local EuphoriaModule = {}

function EuphoriaModule:Walk(character, speed)
    character.Humanoid.WalkSpeed = speed
end

function EuphoriaModule:Jump(character, power)
    character.Humanoid.JumpPower = power
    character.Humanoid.Jump = true
end

function EuphoriaModule:Crouch(character, crouching)
    if crouching then
        character.Humanoid.HipHeight = 0.5
    else
        character.Humanoid.HipHeight = 2
    end
end

return EuphoriaModule
```

4. In a server script, you can require the EuphoriaModule and use its functions to control the character's movement based on player input or other game events.

Here's an example of how you can use the EuphoriaModule in a server script:

```lua
local EuphoriaSystem = require(game.ServerScriptService.EuphoriaSystem.EuphoriaModule)

game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAdded:Connect(function(character)
        -- You can call EuphoriaSystem functions here to control the character's movement
        EuphoriaSystem:Walk(character, 16)
        EuphoriaSystem:Jump(character, 50)
        
        -- You can also listen for player input or other game events to trigger the EuphoriaSystem functions
    end)
end)
```

This is just a basic example to get you started. You can expand the EuphoriaModule script with more advanced movement functions, animations, and physics to create a more realistic and immersive movement system.
