Lesson 3.1 Unity Learn - Player jump away instead of jump up

Greetings,

While following instructions of Unity Learn Unit 3 - Lesson 3.1, my player showed a weird behaviour and just jumped back spinning away instead of jump up and go down by gravity. Also when I look at Inspector, x, y and z are increasing.
I think the problem is related to "Vector 3" part, but I can't find the cause.

Player has gravity on and constraints are not checked. If I check constraints (except for Y), the player fly up indefinitely while Y stats on Inspector increases.

PS: I had to recreate the scenario because Unity assets pack for this lesson got errors.

Any idea about what is causing this Olympic movement?
Thank you in advance.





Code is below:

public class PlayerController : MonoBehaviour
{
private Rigidbody playerRb;
public float jumpForce = 10f;
public float gravityModifier;

// Start is called before the first frame update
void Start()
{
playerRb = GetComponent<Rigidbody>();
Physics.gravity *= gravityModifier;
}

// Update is called once per frame
void Update()
{
if (Input.GetKeyDown(KeyCode.Z));
{
playerRb.AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
}
}
}

 

Remove the semicolon from this line:

if (Input.GetKeyDown(KeyCode.Z));

 

Thank you, Valjuin.

I also found out that the axis of my project were changed and the camera too.
So my gravity was pulling left. That made my player "fall to the left".
Very junior mistake. =)
