Script Instantiates only one platform?
I have 5 quads with a spawn script that spawns 3 types of platforms. So in total there are 5 platforms. My problem is that in the update method when reinstantiate is equal to true, it only instantiates 1 platform instead of 5. (so there are 6 when there should be 10). Here's the script: using UnityEngine; using System.Collections;
public class EMplatformSpawn : MonoBehaviour {
public GameObject[] Pobj; // P for platform
public static bool reinstantiate = false;
void Start () {
Pspawn ();
}
// Update is called once per frame
void Pspawn ()
{
Instantiate(Pobj[Random.Range(0, Pobj.GetLength(0))], transform.position, Quaternion.identity);
}
void Update()
{
if (reinstantiate == true)
{
Pspawn();
reinstantiate = false;
}
}
}
Thanks in advance! :)
The first time Update() in one of the 5 scripts runs, it sets reinstantiate to false. So the other 4 scripts fail the if (reinstantiate == true) check. You would only ever see 1 platform spawn, as you describe.
You need some mechanism that allows all 5 scripts to spawn without resetting the global flag and without processing it more than once. There are very many ways to do this from simple to complex, reliable to error-prone, etc.
A simple way would be:
public static int reinstantiateFrame = -1;
void Update()
{
// If the next spawning is scheduled for this frame, spawn
if (reinstantiateFrame == Time.frameCount)
{
Pspawn();
}
}
Then set reinstantiateFrame = Time.frameCount + 1;. (There is no guarantee of script Update() order, so I had to put spawning on the next frame. You can also set it to current frame if you spawn in LateUpdate().)
