rigidbody2D only jump while grounded
Hello I am a new user to Unity and I am currently using JavaScript. Right now i have a question on how to make it that my rigid body can only jump while being grounded. Right now you can press W over and over and go flying up into the sky. I am using the code
pragma strict
var jumpSpeed: float = 10;
function Start () {
} function Update () { if (Input.GetKeyDown (KeyCode.W)){
rigidbody2D.velocity.y = jumpSpeed; }
}
Any help would be greatly appreciated! The ground i am using is completely flat!
In the future use the 101/010 button to format your code. The quotation button does not work well for code.
You'll get a better answer for your question if you describe your ground. There are several ways to detect if you are grounded...some specific 'y' value, raycasting down and checking the distance, detecting a collision with the ground to name three.
If you want the character to move and jump on inputs, you can use CharacterController.
Following commented code is right for you.
var groundCheck : Transform;
var b_grounded : bool = false;
function Start ()
{
groundCheck = transform.Find("groundCheck");
}
// Update is called once per frame
function Update () {
b_grounded = Physics2D.Linecast(transform.position, groundCheck.position, 1 << LayerMask.NameToLayer("Ground"));
print(b_grounded);
}
}
I'm not familiar with javaScript but i've c# code which be can used to detect character is grounded or not,
using UnityEngine;
using System.Collections;
public class GroundTest: $$anonymous$$onoBehaviour {
// Use this for initialization
private Transform groundCheck;
bool b_grounded = false;
void Start ()
{
groundCheck = transform.Find("groundCheck");
}
// Update is called once per frame
void Update () {
b_grounded = Physics2D.Linecast(transform.position, groundCheck.position, 1 << Layer$$anonymous$$ask.NameToLayer("Ground"));
print(b_grounded);
}
}
Hey hirenkicha I cant use Character Controller because I am using the new Unity 2D features. Is the script still viable to use?
yes.. you can use. Just add a layer to the ground sprite as "Ground" and a gameobject named "groundCheck" at the feet of the character which will check for the ground layer
Thank you! Now I just need to fix my darn $$anonymous$$ono Develop, sorry for being slow, I literally just joined this morning:)
