Jumping and moving forward a Unity2d character?

Question

VMware

Good day! I would like to ask how to implement so that the character can jump and move forward at the same time when pressing one space ? And the second point, how to make the jump force when holding the space bar?
The game will be something like a jumper game in VK only 2d.

Vector2 jump = (transform.up * jumpForce) + (transform.right * 50);

        if (Input.GetKeyUp(KeyCode.Space))
        {
            rb.AddForce(jump, ForceMode2D.Impulse);
        }

Answer 1

Use the character's velocity .
