I want to call an event every X seconds where X is variable. I've looked into InvokeRepeating but it seems like I can't modify the rate after calling the method. I think the best way would be to use a repeating coroutine. Does StartCoroutine_Auto do this? I'm a bit confused as to how it works. If anyone can show me an example, I'd really appreciate it. Thanks.

Check timer time when changed it.
Hello. I have a question that i cant solve my self. I am making tower defence game and i added rapid fire upgrade that change time value in the time but its still the same speed because it does not check it when i buy that upgrade. How can i make that when i purchase it, it will check the timer after the upgrade is applied then it will start using the new time i hope you understand. I am using unity 5 beta pro. Here is the timer script:
using UnityEngine;
using System.Collections;
public class TurretShooting : MonoBehaviour {
public Rigidbody cannonball;
public Transform cannonend;
private float cannonballspeed = 1500f;
public float firerate = 3.0f;
public void Start () {
InvokeRepeating("shootcannonball", 1, firerate);
}
void shootcannonball () {
Rigidbody cannonballrig;
cannonballrig = Instantiate (cannonball, cannonend.position, cannonend.rotation) as Rigidbody;
cannonballrig.AddForce (-cannonend.forward * cannonballspeed);
}
}
See that firerate in invokerepeating timer? yeah the upgrade change that value but it does not detect it and keeps using the old time. How can i make that it would check in this upgrade script:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class CannonRateOfFireUpgr : MonoBehaviour {
private Databasestorage database;
private int Cost = 15;
public GameObject Cannon1;
public GameObject Cannon2;
// Use this for initialization
public void increaserateoffire () {
database = GameObject.Find ("Main Camera").GetComponent ();
//Cannon3 = GameObject.Find ("Cylinder001").GetComponent ();
//Cannon4 = GameObject.Find ("Cylinder001").GetComponent ();
if (Cannon1.GetComponent ().firerate < 0.2f && Cannon2.GetComponent ().firerate < 0.2f) {
transform.Find ("CannonRateOfFireText").GetComponent ().text = "Cannon Rate Of Fire\nMAX UPGRADED";
} else {
if (database.money > Cost) {
database.money -= Cost;
Cannon1.GetComponent ().firerate -= 0.1f;
Cannon2.GetComponent ().firerate -= 0.1f;
//Cannon3.GetComponent().firerate -= 0.1f;
//Cannon4.GetComponent().firerate -= 0.1f;
Cost += 12;
transform.Find ("CannonRateOfFireText").GetComponent ().text = "Cannon Rate Of Fire\nCost " + Cost;
}
}
}
}
I tried adding the Start() in the button but it start a new timer and then its shooting 2 bullets at 1 time... that is bad. Soo how can i check it? sorry again if this is very confusing.

InvokeRepeating on object with DontDestroyOnLoad
I'm having an issue where I have a method that is invoked using InvokeRepeating, and whenever I change scenes the entire thing locks up. I've found that this is because within that repeating method I'm reading from a stream using ReadLine, which waits for the end of the line before proceeding. However, When I load my new scene it seems that the main thread takes over because the game locks up until I send that stream input, and which point it unlocks and then immediately locks back up waiting for more input.
Any suggestions on how to fix this?..
I've already tried flushing the stream, closing the stream, and canceling the Invoke on the MonoBehaviours Awake method and then re-invoking it. I've also tried doing the same in the OnLevelWasLoaded method.

InvokeRepeating a trigger collider?
I have a trigger that is to damage any entity that passes through it
I want to use InvokeRepeating to control delay of damage so it wont call it every frame
this is my code
using UnityEngine;
using System.Collections;
public class TriggerDamage : MonoBehaviour
{
public float DamageAmmount = 5.0F;
public float Delay = 5.0F;
void OnTriggerStay(Collider ent)
{
InvokeRepeating("Damage", 0f, Delay);
}
void Damage()
{
ent.gameObject.SendMessage("EntityDamage", DamageAmmount, SendMessageOptions.DontRequireReceiver);
}
}
And this is my error
Assets/Scripts/TriggerDamage.cs(17,17): error CS0103: The name 'ent' does not exist in the current context
I understand the damage void has no reference to the collider name, so how can i do this?
Or is there a better way than invoke repeating?

Shooting Projectiles With controlling attackSpeed
Hi I Have two Scripts ProjectileMotion and FSMArcherTower. I will brief you on how it works then ill tell you the problem. I Have attached both scripts to this tower and it shoots a projectile. Right now I have managed it to work almost the way i want but the code is a bit confusing. I have created a FSM in FSMArcherTower where In my update method I have Switch cases for different states of the tower. However I cannot call InvokeRepeating or StartCoroutine in update as it is called every frame. Thus I have called StartCoroutine In Start and created a while loop in the Co routine. The PROBLEM is that the code in public IEnumerator States() is not clean as attackSpeed variable is actually the input for yield waitForSeconds which if the value of attackSpeed is less causes to be actually More attack Speed. I just want a better way to use coroutines and Invoke and update in this situation. Any Insight will be helpfull. Thank you
public class FSMArcherTower : MonoBehaviour {
public enum ArcherTowerState
{
Idle,
Attacking,
Destroyed
}
public ArcherTowerState currentArcherTowerState;
// Less is more speed
// so 0.1f is faster attackSpeed than 0.9f

how to decrease repeating time in invokerepeating?

how to stop InvokeRepeating when it calls a function in 0.1 second?
Hello,
i have InvokeRepeating to call a function (kills a monster and damage in 0.1second) the problem is when this monster is dead and he drops loot the invokeRepeating calls the loot function 5 times instead of one time only.
i tried cancelinvoke but didnt work and i tried to check for a boolean and make it false inside the function but didnt work.
i think the problem here is because the invokerepeating calls the function so many times before it cancels, so who can i stop that?
here is an example of what i am saying:
void Start ()
{
InvokeRepeating("DoingDPS",0,0.1f);
}
void DoingDPS () // original function
{
MonsterHealth-=Dps;
if(MonsterHealth<=0)
{
//Kill it and drop items
}
}
void DoingDPS () //function with bool check
{
MonsterHealth-=Dps;
if(MonsterHealth<=0)
{
if(DoOnce)
{
DoOnce=false;
//Kill it and drop items
}
}
}
void DoingDPS () // function with cancelinvoke
{
MonsterHealth-=Dps;
if(MonsterHealth<=0)
{
CancelInvoke("DoingDPS");
//Kill it and drop items
}
}

InvokeRepeating does not work in UNET
Well I am making a multiplayer 2D space shooter game and the player is supposed to shoot at a fixed rate when the screen is touched/held. It worked normally but when I began converting the game to multiplayer, the CmdShoot method does not work. (although it works without the invokeRepeat).. I tried to use coroutine but it said Command methods cannot be coroutines... so how should i shoot at a fixed rate then?

Perfect sinus
Hi,
I'd like to be able to send a sinus to an external device .
When launching my function, i start a timer :
time Sinus = Stopwatch.StartNew ();
To avoid Update, i used InvokeRepeating()
And i compute:
pos1 = float.Parse( Amplitude.text) * (Mathf.Sin (float.Parse(Frequency.text) *timeSinus.ElapsedMilliseconds / 1000f)));
The probleme is that output is not constant : it works generaly well and sometime some part are completely missing (not go to greatest or lowest value)

Missing Reference Exception
Hi guys.
I am trying to make a game object, in this case a battery, spawn around the room.
i have created a cylinder with a battery texture and put it in the scene.
using UnityEngine;
using System.Collections;
public class Battery_Script : MonoBehaviour {

void Start () {
InvokeRepeating("Spawn", 5 , 5);
}
void Spawn() {
int i = Random.Range (0,spawns.Length);
transform.position = spawns[i].position;
transform.rotation = spawns[i].rotation;
}
}
i have attached this script to it and i keep getting the error message
"MissingReferenceException: The object of type 'Battery_Script' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.
UnityEditor.GenericInspector.GetOptimizedGUIBlock (Boolean isDirty, Boolean isVisible, UnityEditor.OptimizedGUIBlock& block, System.Single& height) (at C:/buildslave/unity/build/Editor/Mono/Inspector/GenericInspector.cs:19)
UnityEditor.InspectorWindow.FlushOptimizedGUIBlock (UnityEditor.Editor editor) (at C:/buildslave/unity/build/Editor/Mono/Inspector/InspectorWindow.cs:1430)"
i think its only being called once because collapse isn't checked on the console so i assume its happening on start.
i don't destroy it at any point so i'm stumped.
i'm sure i'm missing something obvious :) so thanks in advance.

Invokereapeating not calling function
So ive gone over several other unity answers and cannot seem to find why invokerepeating is not firing my function. I call it in the start function like this:
void Start ()
{
InvokeRepeating("LSCycle", 1f, 5f);
}
After that the code works as normal until i get to the LSCycle. Which looks like this:
void LSCycle(){
Debug.Log("Life Support Cycle Started! c: ");
//edit: emptied out the code between the debug.logs
Debug.Log("Life Support Cycle Ended! c: ");
}
For some reason none of the debug.logs ever show up, and the numbers i try to update with the invoke do no update. I know its probably something incredibly simple but i cannot seem to find why it doesnt call. Any help would be appreciated. Thanks!

How can I get my platforms to randomly appear when not activated by button
So I'm building a game and the first puzzle is a jumping puzzle.
I have already created a button collision so that when the player enters the trigger the platforms will appear for 8 seconds.
However, when the button is not on I want my platforms to all appear at a random rate so if the player wants they can figure out the jumping puzzle without pressing the button.
I have tried InvokeRepeating them so it happens every 0.5 seconds and it says "invoke method couldn't be called" I have also tried a coroutine and that doesn't work properly either.
Any help would be appreciated :)
Thanks :)![alt text][1]

Optimization: how to do a checking less often than within an Update
Right now, this is my code (it is working):
void Update() {
if (Cardboard.SDK.Triggered) {
Application.LoadLevel(Application.loadedLevelName);
}
}
However, it is not needed to perform that check every frame. I'm trying to use the Update function as less as possible. It would be OK to perform that check every 0.5 seconds for instance. I have found the following possibilities:
- [InvokeRepeating()][1]: I wonder if it would increase the performance somehow, or it uses Update internally.
- [FixedUpdate()][2] after configuring Edit -> Project Settings -> Time -> Fixed Timestep: it would change the fixed timestep for the whole game, so I think it would not be a good idea.
