Getting Started

This document describes the steps for creating and controlling a character.

Creating a Character

  • Right-click on the hierarchy window to open the creation dialog and select the Character option from the ECM2 category.

  • It will create an empty character (no visual representation) named Character.

Make sure its origin is set to (0, 0, 0) as this will save you troubles when parenting your model.

  • Parent your model to this newly Character GameObject. For this example, we'll use the included ECM2_Capsule model.

  • In the CharacterMovement component, adjust its radius and height values (this will automatically configure your character’s capsule collider) to better fit your character’s model.

Controlling a Character

In the previous section, we discussed the steps to create and configure our Character. However, at this point, we are unable to move or control it. We will address and resolve this creating a new CharacterInput script.

A Character encompasses a collection of methods designed to facilitate action execution. For instance, its SetMovementDirection method is employed to prompt the character to move in a specified direction (in world space).

Similarly, the Jump method initiates a jump, while the StopJumping method halts the ongoing jump—particularly crucial when a variable jump height is in use.

Likewise, the Crouch method is utilized to initiate the character's crouching action, and the UnCrouch method is employed to cease the crouching state.

The complete script is shown below:

using UnityEngine;
using ECM2;

namespace ECM2.Examples
    public class CharacterInput : MonoBehaviour
        // The controlled Character
        private Character _character;

        private void Awake()
            // Cache controlled character
            _character = GetComponent<Character>();

        private void Update()
            // Poll movement input
            Vector2 inputMove = new Vector2()
                x = Input.GetAxisRaw("Horizontal"),
                y = Input.GetAxisRaw("Vertical")
            // Compose a movement direction vector in world space
            Vector3 movementDirection =;

            movementDirection += Vector3.right * inputMove.x;
            movementDirection += Vector3.forward * inputMove.y;
            // If character has a camera assigned,
            // make movement direction relative to this camera view direction
            if (
                    = movementDirection.relativeTo(_character.cameraTransform);
            // Set character's movement direction vector

            // Crouch input
            if (Input.GetKeyDown(KeyCode.LeftControl) || Input.GetKeyDown(KeyCode.C))
            else if (Input.GetKeyUp(KeyCode.LeftControl) || Input.GetKeyUp(KeyCode.C))
            // Jump input
            if (Input.GetButtonDown("Jump"))
            else if (Input.GetButtonUp("Jump"))

Finally, add the newly created CharacterInput script to your Character GameObject. You should be able to move, jump and crouch!

Crouching and UnCrouching only modify the character's capsule collider.
