How do you instatiate a prefab from a string array?
I've instantiated prefabs from lists many times, but I'd like to know how to do it with an array. The array is string and the prefab is a group of text items with a script containing game objects.
public class VehicleIndexScript : MonoBehaviour
{
public GameObject ID;
public GameObject Make;
public GameObject Model;
public GameObject Year;
public GameObject Mileage;
public void DisplayVehicles(string id, string make, string model, string year, string mileage)
{
this.ID.GetComponent<Text>().text=id;
this.Make.GetComponent<Text>().text=make;
this.Model.GetComponent<Text>().text=model;
this.Year.GetComponent<Text>().text=year;
this.Mileage.GetComponent<Text>().text=mileage;
}
}
Normally, I'd run through the list, make temp variables, then display them as follows:
for(int i = 0; i< List.Count; i++)
{
GameObject brObj = Instantiate(BrakePrefab);
Brakes tmpBrake = BrakeList[i];
DateTime ServiceDate = tmpBrake.ServiceDate;
brObj.GetComponent<BrakesScript>().DisplayBrakes("ID:" +ID, "Date of Service: " +ServiceDate, "Service Location: " +tmpBrake.Location,
"Mileage: " +tmpBrake.Mileage, "Labor: " +tmpBrake.Labor, "Brake Brand: " +tmpBrake.BrakeBrand,
"Brake Price: " +tmpBrake.BrakePrice, "Which Wheels: " +tmpBrake.BrakeWheels,
"Brake Purchase Location: " + tmpBrake.BrakePurchaseLocation, "Brake Notes: " +tmpBrake.BrakeNotes);
brObj.transform.SetParent(BrakeDisplayparent);
}
This data is coming from a WWW call, so rather than trying to convert it, I want to try to keep it as an array, unless someone knows a way to take that information and put it into a class list. Thanks!
What do you mean by "array is string"? Do you have an array of strings and want to instantiate the prefab with the string contents?
It's quite similar to list, although it's important to know that arrays and lists are different.
To go through an array you can also use for loop.
for (int i = 0; i < someArray.Length; i++)
{
var item = someArray[i];
Instantiate(item, transform);
}
Let's say that we have a prefab called Car and then we have a script (class) called Car on the prefab. The car prefab would have properties.
Example:
public class Car : MonoBehaviour {
public string Name { get; set; }
public string Brand { get; set; }
public int MaxSpeed { get; set; }
public double Price { get; set; }
}
void SpawnCar()
{
var carPrefab = Resources.Load("Prefabs/carPrefab") as Car;
var bmw = Instantiate<Car>(carPrefab, transform);
bmw.Brand = "Bmw"; // here you would your string
bmw.MaxSpeed = 160; // and other values
bmw.Name = "Rose";
bmw.Price = 29.999;
}
So, say you want to display the brand, max speed, etc via text game objects and display them?
You would usually have some kind of GUI that would display that information, it depends on the game how it would work though. If you would want to display multiple cars, you would have a prefab for displaying the data, so you would pass that information from each car to each prefab that displays car's details. If you want to display one car information at the time, you would have static gameobjects that hold text components, you would still be able to change those at run time but you will be limited to how many game objects with text components you have and of course if you had a prefab, you could instantate as many of them as you want to display all cars at the same time.
True, all true, but how would you do that with the scripts I have above?
