Question by RealSkizze · Aug 23, 2019 at 09:10 PM · 2d game2d-platformer2d-physicsforceforces

How to i add force in a angle i have got?

I have an angle and I want to add force in that direction. It is a 2d game here is the code for the script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;

 public class PlayerController : MonoBehaviour
 {
     public float movementSpeed = 3.0f;
     float movement = new float();
     public float shootdirection;
     public float recoildirection;
     public Vector2 flydirection;
     Rigidbody2D rb2D;
 
     private void Start()
     {
         rb2D = GetComponent<Rigidbody2D>();
     }
 
     private void Update()
     {
         
     }
 
     private void FixedUpdate()
     {
         setvalues();
     }
 
     void setvalues()
     {
         shootdirection = GameObject.Find("Arrow").GetComponent<PointerController>().z_rotation;
         recoildirection = GameObject.Find("Arrow").GetComponent<PointerController>().thrustdirection;
     }
 
     void blast()
     {
         
     }
 }

Hi, you should have included what angle exactly you mean.

I assume you want to add a force to the player along the recoil direction, no?

I am currently not at my machine, so I can only give you a pointer, as I can't double check the code if it works. Also, I have no idea what a pointer controller is, so I'll just try to find a general purpose solution for you (I can't find that in the documentation (aside from open-VR, which seemed odd considering 2D)).

I'd go with Rigidbody2D.AddForce(new Vector3 (0,0, whateverZRotationYouNeed)).

All in all, I think the issue is in working with said PointerController. While it might be a nice shortcut, anything that is not findable in the documentation is hard to work with.
