Animating a sprite in 2 directions

Unity Engine
1

Hi, haven’t been using unity for long and my knowledge of C# is quite lacking. I have a 2D sprite for a platformed which I’ve assigned a run animation to. I’m having trouble assigning code so that the animation will play both when he’s running right and left (currently it’s just left). Here’s the code:

voidMoveCharacter (){
if (Input.GetKey (KeyCode.LeftArrow)) {
run = true;
} else {
run = false;
}

if (Input.GetKey (KeyCode.Space)) {
jump = true;
} else {
jump = false;
}

animator.SetBool (“run”, run);
animator.SetBool (“jump”, jump);
}

Any help with this? Thanks!

Hi,

I’m new too, but I think have a solution for you.

Why not just simply rotate the x axis to the negate.

Like that:

void Flip(){
        Vector3 theScale = transform.localScale;
        theScale.x *= -1;
        transform.localScale = theScale;
    }

ahem you have only if (Input.GetKey (KeyCode.LeftArrow)) { there

You need to take account also RightArrow. :roll_eyes:

something like that ?

voidMoveCharacter (){
if (Input.GetKey (KeyCode.LeftArrow)) {
run = true;
jump = false;
} else {
run = false;
}

if (Input.GetKey (KeyCode.Space)) {
jump = true;
run = false;
} else {
jump = false;
}

animator.SetBool (“run”, run);
animator.SetBool (“jump”, jump);
}

Sir (or madam), I’m going to make you a big favor: what if you’d take it slowly and carefully read what was written… and then try it again.

Good luck.

No I get that, I know how to code it for left OR right, I just can’t figure out how to do both…

You can achieve what you want to do by using an operator after the Input for the left. Have a look at these pages:

If you need more help, don’t be hesitated.

@sandbaydev : I don’t want give all the code… I just want explain.

You can detect ! See that:

using UnityEngine;
using System.Collections;

public class playerControlScript : MonoBehaviour {
    public float maxSpeed = 50;

    private Vector2 movement;
    private bool isRight;

    void Update () {
        movement = new Vector2(
            inputX * maxSpeed,
            0);

        if (inputX > 0 && isRight == true) {
            Flip();
            isRight = false;
        }

        if (inputX < 0 && isRight == false) {
            Flip();
            isRight = true;
        }
    }

    void FixedUpdate()
    {
        rigidbody2D.velocity = movement;
    }

    void Flip(){
        Vector3 theScale = transform.localScale;
        theScale.x *= -1;
        transform.localScale = theScale;
    }
}
