How do I stop my character from jumping infinite times?

Questions & Answers
1

I am trying to make my character jump only once, but it can jump as many times as the “W” key is pressed. Another problem is that it can just stick to a wall, basically meaning it can easily climb walls when it is not supposed to. Here is my code, any help would be greatly appreciated: public float moveSpeed;
public float jumpHeight;
Rigidbody2D character;

void Start()
{
	character = GetComponent<Rigidbody2D>();
}

void FixedUpdate()
{
	if (Input.GetKey(KeyCode.S))
	{
		character.velocity =  Vector3.down * moveSpeed;
	}
	else if (Input.GetKey(KeyCode.W))
	{
		character.velocity =  Vector3.up * jumpHeight;
	}
	else if (Input.GetKey(KeyCode.D))
	{
		character.velocity =  Vector2.right * moveSpeed;
	}
	else if (Input.GetKey(KeyCode.A))
	{
		character.velocity =  Vector3.left * moveSpeed;
	}

}

Hey. There are several ways you can ensure that multiple jumps do not occur. You can disable the “W” input until he lands using a yield WaitForSeconds() function. Or you could disable it with OnCollisionExit, and re-enable it with OnCollisionEnter (with the ground).
Hope this helps:)
