2D multiple direction movement with arrows problem

Questions & Answers
1

Hello,

I am creating a 2D horizontal shmup and I can’t find what’s the problem with movement.

  1. Movement without firing works fine.
  2. Movement with firing (spacebar) with keys WASD works fine.
  3. Movement with firing (spacebar) with arrow keys when moving x axis positive (right) + y axis positive (up) works fine. Same with both axes negative.
  4. Movement with firing (spacebar) with arrow keys when axes are opposite (I.E. x negative, y positive) doesn’t work. The character moves in single direction.

Here is the code (problem is probably within Update() function):

using UnityEngine;
using System.Collections;

public class PlaneParameters : MonoBehaviour {
	public float fireRate = 0;
	public float Speed = 2;
	public float movementSpeed = 2;
	public Transform bulletPrefab;
	private float timeToFire = 0;
	private Transform firePoint;

	void Awake (){
		firePoint = transform.FindChild("FirePoint");
		if (firePoint == null){
			Debug.LogError ("Can't find Plane child FirePoint");
		}
	}

	void Start (){
	}

	// Update is called once per frame
	void Update () {

		// movement with camera
		transform.Translate(Vector3.right * Speed * Time.deltaTime);

		//player input movement
		if (Input.GetButton ("Horizontal")){
		transform.Translate(new Vector3 (Input.GetAxis("Horizontal") * movementSpeed * Time.deltaTime,0f,0f));;
		}

		if (Input.GetButton ("Vertical")){
		transform.Translate(new Vector3 (0f,Input.GetAxis("Vertical") * movementSpeed * Time.deltaTime,0f));
		}

		//restrictions within screen
		var pos = Camera.main.WorldToViewportPoint(transform.position);
		pos.x = Mathf.Clamp01(pos.x);
		pos.y = Mathf.Clamp01(pos.y);
		transform.position = Camera.main.ViewportToWorldPoint(pos);

		//firing

		if (Input.GetKey (KeyCode.Space) && Time.time > timeToFire){
			timeToFire = Time.time + 1/fireRate;
			Instantiate(bulletPrefab, firePoint.position, firePoint.rotation);
		}
	}

	void OnCollisionEnter2D(Collision2D col) {
		if (col.gameObject.tag == "Enemy")
			{
			Application.LoadLevel("restartScreen");
			}
		}
}

Any ideas what’s wrong?

Thanks in advance.

I think I did not understand the problem…
When you press, for example, Right (X-positive) and Down (Y-negative), the movement is happening in only one of these directions?

I guess you could you try removing the “if(GetButton(“Vertical/Horizontal”))” before the

transform.Translate(new Vector3 (0f,Input.GetAxis(“Vertical”) * movementSpeed * Time.deltaTime,0f));
