Spawning animals at a random postion on platforms.
Im making an action 2D platfomer, and to make the world more alive, I wanted to add someanimals that will jump around and stuff. BUT I dont know how to make them spawn on the level, and not just spawn in it, or fall out of the level.
^ the kind of level these animals are gonna spawn on.
You know the width and height of the map? get a random point within that range, raycast down to find the closest ground level point and spawn an enemy on that point.
You can make empty game objects located at where you want your animals to spawn with the tag SpawnPoint and make the animals instantiate at a random spawn point. (untested code)
public GameObject animal; // animal you want spawned
// Start is called before the first frame update
void Start()
{
// an array of spawn points
GameObject[] spawnPoints = GameObject.FindGameObjectsWithTag("SpawnPoints");
// does this code 3 to 5 times (you can replace the value with whatever you want)
for (int i = 0; i < Random.Range(3, 5); i++)
{
int spawnPointindex = Random.Range(0, spawnPoints.Length); // random number between 0 and the number of spawn points
// pick a random spawn point from the array and get the position of it
Vector3 randomPos = spawnPoints[spawnPointindex].GetComponent<Transform>().position;
// instantiate animal at random position
Instantiate(animal, randomPos, Quaternion.identity); // instantiate the animal at the random position
}
}
If you want random animals, you can turn the variable animal into an array and get a random index of the array and spawn that animal.
public GameObject[] animals; // array of animals
getting a random animal from the array: (put this code inside the for loop and replace animal with randomAnimal)
int animalIndex = Random.Range(0, animals.Length);
GameObject randomAnimal = animals[animalIndex];
@Rapizer thanks for the answer, but It is not truly random. Since its preset spawn points.I would rather not spam spawn points all over the place. I can, but that might be to many game objects.
