Question by ZilvinasKrasauskas · Sep 18, 2016 at 02:10 PM · 2d-platformerjumpinggroundground detection

Jump if ground is detected

Hello! I have a feeling this kind of thing has been asked a lot of times, and I'm sorry for having to ask once more. I'm a Unity beginner & a C# novice. I've watched multiple tutorials, read the documentation and tried out multiple ways to achieve what I'm trying to. The result I'm looking for is that my stickman, with a polygon collider 2 could only jump when it hits a box collider 2d, which is my ground. Right now it can just jump a lot of times. I tried doing a cooldown and numerous other ways but nothing is working for me for some reason. I'm going attach my code without any attempts in it if anyone could show me how they'd do it. using UnityEngine; using System.Collections; using UnityStandardAssets.CrossPlatformInput;

 public class Controls : MonoBehaviour
 {
     public float JumpSpeed = 40.0f;
     public float moveForce = 1;
     Rigidbody2D Body;
     private Animator anim;
 
     void Start()
     {
         Body = this.GetComponent<Rigidbody2D>();
         anim = GetComponent<Animator>();
         Body.isKinematic = false;
         Body.freezeRotation = true;
 }
 
     void FixedUpdate()
     {
         Vector2 moveVec = new Vector2(CrossPlatformInputManager.GetAxis("Horizontal"), CrossPlatformInputManager.GetAxis("Vertical")) * moveForce;
 
         if (CrossPlatformInputManager.GetButtonDown("Jump")) 
         {
             Jump();
         }
         Body.AddForce(moveVec);
         anim.SetFloat("hSpeed", Mathf.Abs(Body.velocity.x));
 
     }
     void Jump()
     {
             Body.AddForce(Vector3.up * JumpSpeed);
     }
 
 }

Does your player have a box collider?

//jump variables

 bool grounded = false;

 float groundcheckRadius = 0.2f;

 public LayerMask groundLayer;

 public Transform groundcheck; //create an empty gameobject which will be used for checking ground. Attach the gameobejct just below the player.

 public float jumpheight;


void FixedUpdate()

 {
     //check if we are on ground

     grounded = Physics2D.OverlapCircle(groundcheck.position, groundcheckRadius, groundLayer);

          
     //for jump
     if (grounded && Input.GetAxis("Jump") > 0)

     {

         grounded = false;
         myAnim.SetBool("isGrounded", grounded);
         myRB.AddForce(new Vector2(0, jumpheight));

     }
 }
