2D character controller

I am trying to create a character controller for a 2d platformer (I mean without a rigidbody). I have looked online but could not find any good tutorials. Does anyone know where a good tutorial for this is? Or is it better to just try to find things that are related to it, and piece information together? And if so, can I get some pointers on where to start? Thanks.

 

I have exactly such a thing here: 2D Animation Methods in Unity. Be sure to download the demo project, since Gamasutra mangles the code a bit.

 

Where is the example project?

 

Oh nevermind I found it

 

How would one implement collisions and walls into this?

 

Will I show a C# script for 2D character controller?

 

What?

 

Will I show the script?

 

Say yes if you want.

 

Yes

 

And, it will be with a rigidbody2D

 

And to move you need to use WAD.
W to jump, A to move left, D to move right

 

Code (CSharp):

1. using UnityEngine;
2.  
3. public class Player : MonoBehaviour
4. {
5.     Rigidbody2D Rig2D;
6.     public float Speed = 5f;
7.     public float JumpForce;
8.  
9.     void Start()
10.     {
11.         Rig2D = GetComponent<Rigidbody2D>();
12.     }
13.  
14.     void FixedUpdate()
15.     {
16.         if (Input.GetKey(KeyCode.A))
17.         {
18.             transform.position -= transform.right * Speed *
19.                 Time.deltaTime;
20.         }
21.         if (Input.GetKey(KeyCode.D))
22.         {
23.             transform.position += transform.right * Speed *
24.                 Time.deltaTime;
25.         }
26.     }
27.     private void OnCollisionStay2D(Collision2D Collision2D)
28.     {
29.         if (Input.GetKeyDown(KeyCode.W))
30.         {
31.             Rig2D.AddForce(new Vector2(0, JumpForce * 50));
32.         }
33.     }
34. }

sorry, still quite Buggy...

 

Please name your script "Player"

 

Hmmm not quite what Im looking for

 

And what do you want?
What game do you want to make?
Do you make your terrain with tilemap?

 

Oh, yes, there is a bug, you can clim up the wall.

 

A controller that doesnt use rigidbody mainly because it has difficulty handling slopes and isnt quite as easy to fine tune as a character controller

 

No rigidbody?!

 

Yes.... a character controller that functions without a rigidbody

 

than i don't know how to do it

 

Why no rigidbody?

 

Because, if there is a slope then the rigidbody may slide down/get stuck when moving up it which is not ideal for some platformers

 

Well, I will try to find a way to fix it.

 

using UnityEngine;

public class CharacterController2D : MonoBehaviour
{
public float WalkSpeed = 10;
public float JumpForce = 5;

void Update()
{
var Move = Input.GetAxis("Horizontal");
transform.position += new Vector3(Move, 0, 0) * Time.deltaTime * WalkSpeed;

if (Input.GetButtonDown("Jump") && GetComponent<Rigidbody2D>().velocity.y == 0)
{
GetComponent<Rigidbody2D>().AddForce(new Vector2(0, JumpForce), ForceMode2D.Impulse);
}
}
}


here is my 2d characterController. If you want to copy this make shore that you have a rigidbody on your player and freeze position x and freeze rotation z on contraints in your rigidbody component and change your scripts name to CharacterController2D or else its not gonna work.

 

Code (CSharp):

1. using UnityEngine;
2.  
3. public class CharacterController2D : MonoBehaviour
4. {
5. public float WalkSpeed = 10;
6. public float JumpForce = 5;
7.  
8. void Update()
9. {
10. var Move = Input.GetAxis("Horizontal");
11. transform.position += new Vector3(Move, 0, 0) * Time.deltaTime * WalkSpeed;
12.  
13. if (Input.GetButtonDown("Jump") && GetComponent<Rigidbody2D>().velocity.y == 0)
14. {
15. GetComponent<Rigidbody2D>().AddForce(new Vector2(0, JumpForce), ForceMode2D.Impulse);
16. }
17. }
18. }
