New to unity but got a player setup with stand, idle and walk animations but really unsure on jump and running scripts. any help is appreciated, thank you in advance

So the first thing you have to do is add a RigidBody or RigidBody2D component to the Player GameObject.
Then you need to Put a collider/Collider2D component on the ground and make it a trigger, and then tag the Ground GameObject with a Tag like “Floor” (Just remember the name). This will allow you to detect if the player is touching the ground, and therefore can jump. Then you need a script like this:

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour
{
    private Rigidbody2D rb2d; // Store the Players RigidBody Component in the variable rb2d
    public float maxSpeed = 10f; // this is simply to let you mess with the player speed easily
    bool facingRight = true; // this will be used for the direction of the player while moving
    bool onGround; // used for jumping
    // Use this for initialization
    void Awake()
    {
        rb2d = GetComponent<Rigidbody2D>(); // Hooks into the RigidBody Component
    }

    //FixedUpdate is called at a fixed interval and is independent of frame rate.
    void FixedUpdate()
    {
        float move = Input.GetAxis("Horizontal");
        //Store the current horizontal input in the float moveHorizontal.

        rb2d.velocity = new Vector2(move * maxSpeed, rb2d.velocity.y); 
        // Set the Player GameObject's velocity to the Horizontal input of the player

        if (move > 0 && !facingRight) // If the player is moving right and is not already facing right
            Flip(); // Call the Flip Function
        else if (move < 0 && facingRight) // Same as Above for Moving Left
            Flip();
        if (Input.GetKeyDown("space") || Input.GetKeyDown("joystick button 2")) // if either Space or the A Button on a controller is pressed
        {
            if (onGround == true) // And if the player is on the Ground
                {
                rb2d.velocity = new Vector2(rb2d.velocity.x, 4); // Give the player Upwards velocity of 4 (Jump)
            }
                
        }
        
    }
    private void OnTriggerEnter2D (Collider2D floor) // On Entering the Collision of the Floor
    {
        onGround = true;
    }
    private void OnTriggerExit2D(Collider2D floor) // On exiting the Collision of the Floor
    {
        onGround = false;
    }


    void Flip()
    {
        facingRight = !facingRight;
        Vector3 Scale = transform.localScale;
        Scale.x *= -1; // Scale.x -1 Flips the Character, making them change direction
        transform.localScale = Scale; // set the characters scale to this new flipped scale
    }
}

Note that If you’re in 3D, You’ll need to change some of the above, so Vector2 becomes Vector3, with a rb3d.velocity.z part, and OnTriggerEnter2D is just OnTriggerEnter etc. If you need any other help, just ask =P
