Simple Jump Script Help
Hi Guys, I have a problem with my very simple jump script. Basicly i can jump, but before i land i can still keep junping. so when i press space before me player lands if i press space again he will keep jumping for ever. Please help me i am new to c#.
Thank You
using UnityEngine;
using System.Collections;
public class Jump : MonoBehaviour {
public float jumpPower = 1;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if (Input.GetButtonDown("Jump")) {
rigidbody2D.AddForce(transform.up*jumpPower);
}
}
}
use a bool to see if jumping
if(jumping) { //dont allow jump } else { //jumping is good }
i dont get what you mean should i change from float to bool? im a begginer
Use a variable to determine if your player is on the ground, and determine if it is true by using OnCollisionStay, like this:
using UnityEngine;
using System.Collections;
public class Jump : MonoBehaviour {
public boolean grounded = true;
public float jumpPower = 1;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if (Input.GetButtonDown("Jump") && grounded == true) {
rigidbody2D.AddForce(transform.up*jumpPower);
}
}
}
void OnCollissionEnter(){
grounded = true;
}
void OnCollissionExit(){
grounded = false;
}
and that will work better than checking if your jumping, because if he's falling he isnt jumping but you still shouldnt be able to jump.
Collision is spelled wrong and you should set grounded to false in the jump if clause.
the answer is good, but just disable the grounded in case you jumped
if (Input.GetButtonDown("Jump") && grounded == true) {
rigidbody2D.AddForce(transform.up*jumpPower);
grounded = false;
}
everything is great thank you. but when i land i cant jump again
