 o Sketch the character on paper or digitally. Define size and proportions suitable for a
2D game.

2. Design Sprites

o Open your design software. Create a new canvas (e.g., 32x32 or 64x64 pixels for
retro styles).

o Draw and color the character. Focus on creating the base pose for the idle animation.

3. Create Idle Animation Frames

o Create 2-4 slight variations of the character's pose (e.g., subtle breathing
movements).

o Save each frame as a separate PNG file.

4. Import Sprites into Unity

o Add the following script for basic movement:

using UnityEngine;

public class PlayerMovement : MonoBehaviour

public float moveSpeed = 5f;

public Rigidbody2D rb;

 private Vector2 movement;

void Update()

// Input for movement

movement.x = Input.GetAxisRaw("Horizontal");

movement.y = Input.GetAxisRaw("Vertical");

void FixedUpdate()

// Apply movement

rb.MovePosition(rb.position + movement * moveSpeed * Time.fixedDeltaTime);

4. Test Movement

o Press Play in the Unity Editor to test the movement system.

if (other.CompareTag("Player"))

Destroy(gameObject); // Remove the coin

o Attach this script to the coin object and ensure the player has the "Player" tag.
