Unity gMetrix Module 9

A programmer set up a UI button and added a GameObject with the following code to the On Click event: private void LoadGame () { Debug.Log("Load game code here ... "); } The goal is to call LoadGame when the button is pressed, but the method is not showing on the functions dropdown button.

What is causing this issue?

• LoadGame will not show if there is only a Debug.Log method inside.

• LoadGame should be public in order to be shown on the dropdown.

• SceneManagement namespace is not added to the script.

• Ul buttons can't be used to load other scenes.

Answer explanation

Only public methods can be accessed when using an On Click event.

The code below is causing an error. What is most likely the cause of the error? private void OnCollisionEnter2D(Collision collision) { }

• OnCollisionEnter2D needs to be public to collide with another GameObject.

• OnCollisionEnter2D scope can't be empty.

• OnCollisionEnter2D only works with a Collision2D type of parameter.

• OnCollisionEnter2D should have a Collision return type.

Answer explanation

OnCollisionEnter2D only works with Collision2D type of parameter. When OnCollisionEnter2D gets called, the parameter receives a Collision2D type

True or False: OnTriggerEnter2D works only if the GameObject with the code inside has either a BoxCollider or a BoxCollider2D component setup.

• True

• False
