Questions & Answers

I’ve been doing the “Roll a ball” tutorial, and i thought i had done everything as it needed to be. But it keeps nagging me about 3 errors. If anyone please can explain to me what i’ve done wrong, i’d really appreciate it.

using UnityEngine.UI;
using System.Collections;

public class PlayerController : MonoBehaviour 

{	
	public float speed;
	public Text countText;
	private int count;

	void start ()
	{
		count = 0;
		SetCountText ()
	}

	void FixedUpdate ()
	{
		float moveHorizontal = Input.GetAxis ("Horizontal");
		float moveVertical = Input.GetAxis ("Vertical");

		Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);

		rigidbody.AddForce (movement * speed * Time.deltaTime);
	}

	void OnTriggerEnter(Collider other)
	{
		if(other.gameObject.tag == "Pickup")
		{
			other.gameObject.SetActive(false);
			count = count + 1;
			SetCountText ()
		}
	}

	void SetCountText ()
	{
		countText.text = "Count" + count.ToString ();
	}
}
