top down 2d game, aim weapon with mouse. please help
So i have tried some different solutions on this but every piece of code i have tried gives me the same result. im trying to make a 2d top down game where you can shoot. i have a weapon in front of my character which shoots. when my mouse is close to the character it seems accurate but the further i go the less accurate it becomes for some reason.
the blue line is just something i added to easier watch how unaccurate it is btw.
my code is
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerController : MonoBehaviour {
Rigidbody2D rbody2d;
Animator anim;
Vector2 mouseDir;
Vector2 movement;
Vector3 mousePos;
public GameObject weaponSlot;
public float moveSpeed = 5f;
// Use this for initialization
void Start () {
rbody2d = GetComponent<Rigidbody2D> ();
anim = GetComponent<Animator> ();
}
// Update is called once per frame
void Update () {
//player animation based on velocity
if (movement != Vector2.zero) {
anim.SetBool ("isWalk", true);
} else {
anim.SetBool ("isWalk", false);
}
//sets the animation direction based on mouse position
if (mouseDir != Vector2.zero) {
anim.SetFloat ("input_x", mouseDir.x);
anim.SetFloat ("input_y", mouseDir.y);
}
}
void FixedUpdate() {
//gets the position of the mouse
var mousePosition = Camera.main.ScreenToWorldPoint (Input.mousePosition);
Quaternion rot = Quaternion.LookRotation (weaponSlot.transform.position - mousePosition, Vector3.forward);
weaponSlot.transform.rotation = rot;
weaponSlot.transform.eulerAngles = new Vector3 (0, 0, weaponSlot.transform.eulerAngles.z);
mouseDir = new Vector2 (mousePosition.x - weaponSlot.transform.position.x, mousePosition.y - weaponSlot.transform.position.y);
//sets up the horizontal and vertical Vector buttons
movement = new Vector2 (Input.GetAxis ("Horizontal"), Input.GetAxis ("Vertical"));
//movement if horizontal or vertical buttons is pressed
rbody2d.MovePosition (rbody2d.position + movement * moveSpeed * Time.deltaTime);
}
}
if anyone can help me you would really make my day. i have been stuck on this for so long and it was just something i noticed today right when i though my next objective was to make some levels :P
Well, I have this. Put this script in the object you want to move.
public Transform controlThisObject; //Here can be the transform of the weapon
private Vector3 mousePos;
void Update(){
MouseL();
}
//Mouse Look script
void MouseL(){
//Gets mouse position, you can define Z to be in the position you want the weapon to be in
mousePos = new Vector3(Input.mousePosition.x, Input.mousePosition.y, 10);
Vector3 lookPos = Camera.main.ScreenToWorldPoint(mousePos);
lookPos = lookPos - transform.position;
float angle = Mathf.Atan2(lookPos.y, lookPos.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
}
It'll make an object rotate with the mouse pointer(the object will face it), the sprite/object will be facing to the right at the start. It works for me. I use in a top down 2d game, is a ship game.
