Getting a "type expected" error on WaitForSeconds

Questions & Answers
1

Monodevelop is telling me “type expected” between the ( and 3 on the WaitForSeconds of the code.

public class dimensionswitcher : MonoBehaviour {
	IEnumerator Wait();
	yield WaitForSeconds(3);

	bool dimension1 = true;
	bool dimension2 = false;

	void Update () {


		//if player hits z they switch to dim2 and cant switch for 3 sec
			if (Input.GetKeyDown ("z"))
				if (dimension1 == true)

					dimension2 = true;
					dimension1 = false;
					transform.position = new Vector2 (transform.position.x, transform.position.y);
					Wait
		//same as before but switch to dim1
			if (Input.GetKeyDown ("x"))
				if (dimension2 == true)
					
					dimension2 = false;
					dimension1 = true;
					transform.position = new Vector2 (transform.position.x, transform.position.y);	
					Wait	

		}
	}

In C# yield must be followed by a return, and WaitForSeconds is a type, so the proper syntax is

yield return new WaitForSeconds(3);

Your code/script is malformed.

yield can not exist outside of a method that returns IEnumerator, your code need to yield and return or at the very least start a coroutine method.

also calling directly in the update method is bad, start a coroutine instead.

just noticed you’re also missing curly braces.

public class dimensionswitcher : MonoBehaviour
{

    bool dimension1 = true;
    bool dimension2 = false;
    bool waiting = false;

    IEnumerator WaitASec(float seconds)
    {
        yield return new WaitForSeconds(seconds);
        waiting = false;
    }

    void Update()
    {
        if (!waiting)
        {
            //if player hits z they switch to dim2 and cant switch for 3 sec
            if (Input.GetKeyDown("z"))
            {
                if (dimension1 == true)
                {
                    dimension2 = true;
                    dimension1 = false;
                    transform.position = new Vector2(transform.position.x, transform.position.y);
                    waiting = true;
                    StartCoroutine(WaitASec(3));
                }
            }
            else if (Input.GetKeyDown("x"))
            {
                if (dimension2 == true)
                {

                    dimension2 = false;
                    dimension1 = true;
                    transform.position = new Vector2(transform.position.x, transform.position.y);
                    waiting = true;
                    StartCoroutine(WaitASec(3));
                }
            }
        }
    }
}
