Rigidbody2D speed boost when entering a trigger

Questions & Answers
1

I am making a 2D game and I want a 2D rigid body to get a speed boost when entering a 2D trigger, but I cannot get it to work. The object is not getting a speed boost. I am new to coding and am coding in C#. Here is the script I have.

	void OnTriggerEnter2D(Collider2D other) 
	{
		rigidbody2D.AddForce(Vector2(10, 0));   
	}

If you just call rigidbody2D then you’re referring to the triggers. Put other. In front of it

You need to access Rigidbody2D of Collider2D other that is entering the trigger. Keyword new is required for constructors.
void OnTriggerEnter2d (Collider2D other) { other.GetComponent<Rigidbody2D> ().AddForce (new Vector2(10f, 0f)); }

If you use Unity5, you can use the “Area Efctor 2D” compoent to make this
