I assume you attached the movement script to your modeled rocket, right? If you had the Debug.Log statement for KeyCode.Space, does it print to console that you pressed space?
The only other thing I can think of is that maybe your rocket is too heavy? Did you try reducing the mass further to see if the rocket moves. Additionally you could also create and initialize a new variable to boost the thrust output; multiply the (Vector3.up) with your new variable to see if you can get the rocket going.
Thank you for your reply but I tried many things but it doesn’t fly. I increased or decreased the rigidbody’s strength, it still didn’t fly. stays in place. I threw a mesh collider into my own rocket. I don’t know if there is a problem with this. I just realized this. I locked some positions. It is going at a very good speed in the x direction, but not in the up direction. It just doesn’t go up.
Can you show the rocket’s values in the inspector? You showed both together, but I would like to see the rocket by itself.
I think If you unlock the z-axis position it should fly.
You have applied rotations to the model, so your rocket’s z is now pointing up (or down). If you click here
and change it to ‘Local’ you should see that.
But, you don’t necessarily want to unlock the axis. What you want to do is rotate the model without affecting the rotation. To do that, you need to remove the rocket’s visual (model) from the game object, and make it a child of the rocket.
Simple way:
Scene
|- Rocket
|- Model
Another way:
MeshFilter and MeshRenderer)
Scene
|- Rocket
|- Model
thank you very much. you are really professional. Now my rocket is flying. thank you for your help 
My rocket is flying now. I was glad for that, but early. 
. now it doesn’t go left and right when flying 
. what should i do?
Can you show the movement code?
{
[SerializeField] float itmehizi = 100f;
[SerializeField] float donmehizi = 100f;
Rigidbody rb;
AudioSource ses;
// Start is called before the first frame update
void Start()
{
rb = GetComponent<Rigidbody>();
ses = GetComponent<AudioSource>();
}
// Update is called once per frame
void Update()
{
ProcessUcma();
ProcessDonme();
}
void ProcessUcma()
{
if (Input.GetKey(KeyCode.Space))
{
rb.AddRelativeForce(Vector3.up * itmehizi * Time.deltaTime);
if (!ses.isPlaying)//eğer spaceye basıldığında ses çalmıyosa sesi çal
{
ses.Play();
}
}
else //değilse çalma
{
ses.Stop();
}
}
void ProcessDonme()
{
if (Input.GetKey(KeyCode.D))
{
donus(-donmehizi);
}
else if (Input.GetKey(KeyCode.A))
{
donus(donmehizi);
}
}
void donus(float DonBuFrame)
{
rb.freezeRotation = true; //burada dönmeyi dondurduk
transform.Rotate(Vector3.forward * DonBuFrame * Time.deltaTime);//buradaki forward (0,0,1(z)) görevi görüyor.
rb.freezeRotation = false; //burada dönmeyi tekrar açtık
}
}
Looks fine, can you show the rocket after the above changes?
can you connect to my screen with teamviewer? you can solve the problem by yourself
No, I’m not going to do that. You could upload your project somewhere and I can look at it
ok now i will upload a video on youtube
Upload the Unity project. Not a video. Zip it up and put it somewhere that I can download it and open
You have an error in the console. You did not attach an AudioSource to the rocket. Once you do that, the rocket will turn
Finally happened. You tried so hard to solve this. thank you very much 
Hi @hamza99,
Welcome to our community! 
I’m glad to see that bixarrio was able to help you. Is the problem solved?

yes, problem solved. thank you very much. I’m very new to learning unity. If I have any new questions, I will ask again.
