Hi there.
I am new to Unity, I am experimenting with their learning projects.
I made the first rocket project and decided to dabble a bit in it, to experiment several new things. But I got this weird bug in which the ship goes through what I belie it is a very thick wall. I initially wanted to make some labyrinths which would have considerable thinner walls. I have had a very similar issue on another project that I tried to make a long time ago. This same snappy move and the object goes through solid materials.

Here is a short video description of what is happening:

Here is the movement code:

First check gamepad has movement input:

 Vector2 stickDirection = moveDirectionAction.ReadValue<Vector2>();
        if (stickDirection.sqrMagnitude > 0.01f)
        {
            targetDirection = stickDirection.normalized;
            isMoving = true;
        }

Then

        if (isMoving)
        {
            // Smoothly rotate towards the target direction using easing (Slerp)
            transform.up = Vector3.Slerp(transform.up, targetDirection, rotationSpeed * Time.deltaTime);
            
            // Kill any physics spin from collisions so we don't resume spinning when we let go
            rb.angularVelocity = 0f;
            
            // Thrust in the direction the player is currently facing 
            Vector2 thrustDirection = transform.up;


            float currentSpeed = rb.linearVelocity.magnitude;
            
            // Exponential Dropoff
            float speedRatio = currentSpeed / maxSpeed;
            float dropoffMultiplier = Mathf.Exp(-3f * speedRatio); 
            
            // Boost logic
            bool isBoosting = boostAction.IsPressed();
            float currentThrust = isBoosting ? (thrustForce * boostMultiplier) : thrustForce;
            
            float appliedForce = currentThrust * dropoffMultiplier;


            // Enforce a higher max speed if boosting, else normal max speed
            float currentMaxSpeed = isBoosting ? (maxSpeed * 1.5f) : maxSpeed;


            if (currentSpeed > currentMaxSpeed)
            {
                rb.linearVelocity = rb.linearVelocity.normalized * currentMaxSpeed;
            }
            rb.AddForce(thrustDirection * appliedForce);
        }

First, the movement was snappy, I added a rotation speed.
Then, after hitting walls/meteorites, after rotating the ship, when left neutral, it continued the rotation from when it hit the meteorite, before I rotated it with the controller. So I had to kill that inertia.
I don't use any boost in my screen rec, and this behavior was there from the start, even before I used controls (when the ship only moved towards the mouse cursor).

I feel like this is a simple fix/setting, but as I am just beginning, I am really lost :D

Thanks everyone for your help.
