Spawn prefab only in allowed area?
Hello, I'm using this code to spawn a prefab at mouse position, but I only want it to be allowed to be spawned in the area next to street. How can I do this?
if (place_power_plant_coal && Input.GetButtonDown("Fire1")) {
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;
if (Physics.Raycast(ray, out hit)) {
Instantiate(__power_plant_coal, hit.point, Quaternion.identity);
}
}
You could use layers to define the "spawnable" areas, using the RayCast method but with a layermask.

The solution suggested by @Muuskii is a possibility too: http://answers.unity3d.com/questions/119908/instantiating-inside-an-area-only.html
