Moving in one direction at the time

[Laran]

Hello.

I would like to move my character only in one direction at the time (only left, or only top etc). It works correctly but the problem is that when I move horizontally I can go up and down (by pressing W or S) while still pressing A or D (which is OK), but when I move vertically I have to stop pressing W or S to move left or right. I know why this is happening, but I don’t know how to fix that. Here is my code:

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour {

	//Public variable to change speed of the player
	public float MovementSpeed = 20f;

	void Start () {
	
	}

	void Update () {

		float forwardSpeed = Input.GetAxis("Vertical") * MovementSpeed;
		float sideSpeed = Input.GetAxis("Horizontal") * MovementSpeed;


		//This variables will be used to check whether player is pressing keys assigned to Horizontal and Vertical
		bool statusHorizontal = Input.GetButton("Horizontal");
		bool statusVertical = Input.GetButton("Vertical");

		//By default character is not moving
		Vector3 speed = new Vector3 (0, 0, 0);

		//This is stupid, but in original Tanks 1990 player was able to move forward OR to the side
		if (statusVertical == true)
		{
			speed.z += forwardSpeed;
		}
		else if (statusHorizontal == true)
		{
			speed.x += sideSpeed;
		}
		
		
		CharacterController cc = GetComponent<CharacterController> ();

		cc.SimpleMove (speed);

	}
}

Yes, I’m going something a 'la Tanks 1990 to learn Unity.

Figure out this kind of logic can get ugly. I think this is what you are trying to do:

using UnityEngine;
using System.Collections;

public class PlayerController1 : MonoBehaviour {
	
	//Public variable to change speed of the player
	public float MovementSpeed = 20f;

	private bool prevStatusVertical;
	private bool prevStatusHorizontal;
	private bool moveHorizontal;

	private CharacterController cc;
	
	void Start () {
		cc = GetComponent<CharacterController> ();
	}
	
	void Update () {
		
		float forwardSpeed = Input.GetAxis("Vertical") * MovementSpeed;
		float sideSpeed = Input.GetAxis("Horizontal") * MovementSpeed;
		
		
		//This variables will be used to check whether player is pressing keys assigned to Horizontal and Vertical
		bool statusHorizontal = Input.GetButton("Horizontal");
		bool statusVertical = Input.GetButton("Vertical");

		if (statusHorizontal && !prevStatusHorizontal) 
			moveHorizontal = true;
		if (statusVertical && !prevStatusVertical || !statusHorizontal)
			moveHorizontal = false;
		
		//By default character is not moving
		Vector3 speed = new Vector3 (0, 0, 0);
		
		if (statusVertical && !moveHorizontal)
		{
			speed.z += forwardSpeed;
		}
		else if (statusHorizontal)
		{
			speed.x += sideSpeed;
		}

		prevStatusVertical = statusVertical;
		prevStatusHorizontal = statusHorizontal;
		
		cc.SimpleMove (speed);
	}
}
