Question by alpayoguz97 · Mar 06, 2021 at 03:19 AM · transformvelocityaddforce

How can a object be prevented from falling ?

I tried to make projectile for a Spaceship for 3D game. But whenever I instanitate an projectile and make it move, ıt falls . I assume because of rigidbody but couldn't find how to fix. I want projectile to move forward and not fall.

Those are components of projectile

alt text

Those are codes I used to keep projectile from falling.

 public class Projectile : MonoBehaviour 
 {
 
 void Update()
     {
         //transform.position += new Vector3(-1, 0, 0) * 0.1f;
         //GetComponent<Rigidbody>().velocity = -transform.right * 100 * Time.deltaTime;
         //GetComponent<Rigidbody>().AddForce(transform.up * 0.000001f);
     }
 
 }

What do you want then ? From what I understand Lifes_great is right. If you want your projectile not to fall juste uncheck use gravity in the Inspector. Then just add a forward force in the same place where you instantiate the projectile. Something like this should work :
GameObject bullet = GameObject.Instantiate(projectile, transform.position, transform.rotation); bullet.GetComponent().AddForce(weaponCam.transform.forward * shootForce);
