Rotating & fixing the position of an object to one spot
So I've been trying to fix my object to the middle of screen and rotate it with the left and right arrows. I've managed to get it to rotate after some research but it's just constantly rotating. I'm trying to make the object rotate while being able to still shoot. I've been stuck on this code for a bit now and can't seem to fix it to a position and get it to rotate without getting an error/nothing happening/wrong thing happening. Here's the code I've been working with:
using UnityEngine; using System.Collections;
public class PlayerScript : MonoBehaviour { public static int lives = 3; public float speed = 1f; public float turnSpeed = 50f; public float horMin = -6f; public float horMax = 6f; public float vertMin = -4f; public float vertMax = 4f; public GameObject projectile; public Transform socketProjectile; // Use this for initialization void Start () {
}
// Update is called once per frame
void Update () {
float transV = Input.GetAxis ("Vertical") * speed * Time.deltaTime;
float transH = Input.GetAxis ("Horizontal") * speed * Time.deltaTime;
transform.Translate (transH, transV, 0);
Vector3 pos = transform.position;
pos.x = Mathf.Clamp (pos.x, horMin, horMax);
pos.y = Mathf.Clamp (pos.y, vertMin, vertMax);
transform.position = pos;
if (Input.GetKey (KeyCode.LeftArrow))
transform.Rotate (Vector3.up, -turnSpeed * Time.deltaTime);
transform.Rotate (Vector3.up, turnSpeed * Time.deltaTime);
if (Input.GetKeyDown (KeyCode.Space)) {
Instantiate (projectile, socketProjectile.position, socketProjectile.rotation);
}
}
}
Alright. I'll tackle this one part at a time!
Camera: If you want your player to stay in the middle of the screen, you'll have toi make the camera follow the player. You can do this by making a camera controller script, and setting the cameras transform to that of the player, plus the initial offset.
Vectror3 offset = transform-player.transform;
transform = player.transform+offset;
Next you can make your ship stop turning by changing the getkey to getaxis. This removes the need for an if statement, and is generally more preferred than getkey. You can have more than 2 axis, and can set them yourself in unity by going to Edit > Project Settings > Input.
Update()
{
transform.Rotate (Vector3.up, Input.GetAxis("Rotational")*turnSpeed * Time.deltaTime);
}
