Unity2D, how can I make a solid game object on Unity 5?

Hi guys, today while I was creating the player's movements I noticed that the ground was not solid, I tried to put a collider on the player and also a rigidbody2D and for the ground only a collider, but it does not work the same. I also tried using LayerMask but nothing, please help me this thing is leading me to madness xD.

Here is the code :

Code (CSharp):

1.  public class PlayerController : MonoBehaviour {
2.          public bool variablesOnAwake = true;
3.          private Rigidbody2D rb;
4.          public float moveSpeed;
5.          public float jumpHeight;
6.          public Transform groundCheck;
7.          public float groundCheckRadius;
8.          public LayerMask whatIsGround;
9.          private bool grounded;
10.          void Start() {
11.              if(!variablesOnAwake) {
12.                  rb = GetComponent<Rigidbody2D>();
13.              }
14.          }
15.          void Awake() {
16.              if(variablesOnAwake) {
17.                  rb = GetComponent<Rigidbody2D>();
18.              }
19.          }
20.          void FixedUpdate() {
21.              grounded = Physics2D.OverlapCircle(groundCheck.position, groundCheckRadius, whatIsGround);
22.              //////////////JUMP
23.              if(Input.GetButtonDown("Jump")) {
24.                
25.                  Debug.Log("Is Jumping");
26.                  rb.velocity = new Vector2(rb.velocity.y, jumpHeight);
27.                
28.              } else if (Input.GetButtonUp("Jump")) {
29.                
30.                  Debug.Log("Isn't jumping");
31.                
32.              }
33.            
34.              ////////////MOVEMENTS
35.              if(Input.GetKeyDown(KeyCode.D)) {
36.                  rb.velocity = new Vector2(moveSpeed, rb.velocity.y);
37.                
38.              } else if (Input.GetKeyDown(KeyCode.A)) {
39.                
40.                  rb.velocity = new Vector2(-moveSpeed, rb.velocity.y);
41.                
42.              }
43.          }
44.      }

 

Not solid, as in the player is falling through the ground?

You have a sprite for the player & one for the ground? The ground has a collider (not marked as 'trigger') and the player has a collider + a rigidbody2D which is dynamic?

 

Oh now i see, all my ground colliders were setted to trigged! Thx a lot, another question... Can you provide to me a good player controller script for a 2D platformer game?

Take a look at Unity's 2d asset.
