Instanting prefabs at a point then storing them in a list
Hello, Ive got this error and i can't figure it out, I'm new to scripting so bear with me if this is (and probably will be) a incredibly easy fix.
I want to be able to create a prefab at a set location when a button is pressed, (In this case spawnpoint1).. Then, add it to the list of floors for later uses. Ive put an hour in to rearranging code and trying different things and ive just decided to come to you lovely people as i'm sure this is a minuscule problem.
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class creation : MonoBehaviour {
//currency
public float money=0.0f;
//build menu
public bool menu=false;
//building
public List<GameObject> floors = new List<GameObject>();
[SerializeField] Transform floorFab;
void Start ()
{
}
void Update () {
if (Input.GetKeyDown(KeyCode.Tab)) {
menu = !menu;
}
}
void OnGUI() {
if (menu)
{
GUI.Box (new Rect (0, 0, 100, 500), "Menu");
GUI.Label(new Rect(10,25,100,25), "$"+money);
if(GUI.Button(new Rect(0, 50, 100, 20), new GUIContent("Floor 1:", "Price: $100"))){
GameObject floor = (GameObject) Instantiate(floorFab, GameObject.Find("spawnpoint1"));
floors.Add(floor);
}
GUI.Label(new Rect(120, 25, 100, 40), GUI.tooltip);
GUI.tooltip = null;
}
}
}
Your Instantiate() function has invalid arguments. It should be:
GameObject floor = (GameObject) Instantiate(floorFab, GameObject.Find("spawnpoint1").transform.position, Quaternion.identity);
In this above line of code the floorFab will be instantiated at the position of the spawnpoint1 game object. I guess this is what you want.
Note: Whenever you get an error always post the exact error message from console for others to know the exact error so that people don't have to keep on guessing and trying to find out where the error might be.
I tried your code and, as it is working the way i would like it to, i'm getting an error message when i press the button: "InvalidCastException: Cannot cast from source type to destination type"
I'm thinking this has something to do with the source of the object i'm trying to spawns location in the project window? perhaps if i changed 'GameObject' to 'Transform' i could clear it up
Your type of your floorFab variable should be GameObject.
I actually managed to fix it BY changing floorFab to Transform ins$$anonymous$$d of a GameObject, my project setup is somewhat scattered for a 5 $$anonymous$$ute rush-mock-up, But it seemed to work out in my favor in the end. Thanks for helping Harshad$$anonymous$$, Appreciate it.
