Unity Developers Question:

Consider the following code snippet below:

class Mover : MonoBehaviour
{
Vector3 target;
float speed;

void Update()
{

}
}
Finish this code so the GameObject containing this script moves with constant speed towards target, and stop moving once it reaches 1.0, or less, units of distance?

Answer:

class Mover : MonoBehaviour
{

Vector3 target;
float speed;

void Update()
{
float distance = Vector3.Distance(target,transform.position);

// will only move while the distance is bigger than 1.0 units
if(distance > 1.0f)
{
Vector3 dir = target - transform.position;
dir.Normalize(); // normalization is obligatory
transform.position += dir * speed * Time.deltaTime; // using deltaTime and speed is obligatory
}
}
}

Can threads be used to modify a Texture on runtime?
Can threads be used to move a GameObject on the scene?
Consider the snippet below:
class RandomGenerator : MonoBehaviour
{
public float[] randomList;

void Start()
{
randomList = new float[1000000];
}

void Generate()
{
System.Random rnd = new System.Random();
for(int i=0;i<randomList.Length;i++) randomList[i] = (float)rnd.NextDouble();
}
}
Improve this code using threads, so the 1000000 random number generation runs without spoiling performance.		Okay, we're going to work through a problem here?
