Is there difference between Quaternion.Euler(Obj.transform.rotation.x,Obj.transform.rotation.y,Obj.transform.rotation.z) and Obj.transform.rotation?

Question

I was trying to design a weapon that fires bullets a few degrees less or more than the angle it makes when following the mouse. I was using this code to launch a projectile:

GameObject bullet = Instantiate(bulletPrefab, FirePoint.transform.position,Gun.transform.rotation);
bullet.GetComponent<Rigidbody2D>().AddForce(bullet.transform.up * -2000);

It was working well. Then i changed it into this when i was trying to change trajectory of the bullet.

GameObject bullet = Instantiate(bulletPrefab, FirePoint.transform.position,Quaternion.Euler(Gun.transform.rotation.x, Gun.transform.rotation.y, Gun.transform.rotation.z));
bullet.GetComponent<Rigidbody2D>().AddForce(bullet.transform.up * -2000);

and it started to fire it only downwards even if i move the mouse to different position and i didnt understand why.

Is there any difference between Gun.transform.rotation and Quaternion.Euler(Gun.transform.rotation.x, Gun.transform.rotation.y, Gun.transform.rotation.z) ? And is there any solution to this problem?

Answer 1

当你得到 rotation.x 你得到四元数 (x,y,z,w) 的 x 分量，在你的情况下你需要欧拉角所以得到 rotation.eulerAngles.x
