Player flying into oblivion.

This is the second game im making and when i start the player just flies straight up into space. i know it’s something with the jump but i dont know what. here’s a sample of the code i wrote.

void Update()
if (grounded && Input.GetKeyDown(KeyCode.Space));
anim.SetBool (“Ground”, false);
GetComponent().AddForce(new Vector2 (0, jumpForce));

Thank you in advance

Please format code by highlighting and using the ‘101010’ button.

However even without being formatted, I can see there is a semicolon after the if() statement, which ends the if block and the next lines are run.

The mass is probably really low, so you jump with a lot of force.
