Making a jump with Rigidbody2D character

Questions & Answers
1

I’m trying out the newish Unity 2D features.

I’m trying to make a basic platformer. I’ve got left/right movement working with AddForce but I’m getting stuck on the jump. Here’s what I have:

	if (Input.GetKeyDown(KeyCode.Space) & grounded) {
		jumping = true;
		rigidbody2D.AddForce(jumpForce * Time.deltaTime);
	}

The problem with using the AddForce method is that to get the character to jump I have to set an quite high value to the jumpForce vector, and when adding a big force the character “teleports” quite high quite fast: it’s not a smooth jump.

How would you make a Rigidbody2D jump for a 2d platform game?

In my game I changed its velocity:

var jumpForce : float = 10.0;

rigidbody2D.velocity = Vector2(0,jumpForce);
