2d spawn across screen

Hello,

I am a bit new myself however, you can do the below as an example (since there isn't too much details I am guessing half of what is needed).

To create the object off screen, check the coordinates on the point you want to spawn at (for this example let's say x = -4.62, y = 2 and since it is 2D so z = 0.

To spawn in C# you use the Instantiate keyword and provide a prefab name. To move there are a few methods we'll use MoveTowards as it is easy.

Our code would look similar to the below: public GameObject fishPrefab; public float fishSpeed;

 private Vector3 spawnPosition = new Vector3 (-4.62f, 2, 0);
 private Vector3 position1 = new Vector3 (2, 2, 0);
 
 
 void Start()
 {
 // To Spawn:
 GameObject fish = Instantiate(fishPrefab, spawnPosition, Quaternion.identity) as GameObject;
 
 // To move:
 fish. transform.position = Vector3.MoveTowards(fish.transform.position, position1, Speed * Time.deltaTime);
 }

To make it random you can add the below:

 public GameObject[] fish;
 private int randomPicker;
 private Vector3 spawnPosition = new Vector3 (-4.62, 2, 0);
 private Vector3 position1 = new Vector3 (2, 2, 0);
 void Start()
 {
 
 
 for (int i = 0; i < 3; i++)
 {
 randomPicker = Random.Range(1, 4);
 
 switch (randomPicker)
 {
 case 1:
 GameObject fish1 = Instantiate(fish[1], spawnPosition, Quaternion.identity) as GameObject;
 fish1. transform.position = Vector3.MoveTowards(fish1.transform.position, position1, Speed * Time.deltaTime);
 break;
 case 2:
 GameObject fish2 = Instantiate(fish[2], spawnPosition, Quaternion.identity) as GameObject;
 fish2. transform.position = Vector3.MoveTowards(fish2.transform.position, position1, Speed * Time.deltaTime);
 break;
 case 3:
 GameObject fish3 = Instantiate(fish[3], spawnPosition, Quaternion.identity) as GameObject;
 fish3. transform.position = Vector3.MoveTowards(fish3.transform.position, position1, Speed * Time.deltaTime);
 break;
 }
 }
 }
 

Hope that helps.
