Is there a smarter way to implement event sequencing?
Hi all Unity users,
I'm new to Unity and C# and been trying to get a hang on timing and sequencing using MonoBehavior.Update and Time.delta. I have the following code that chronologically triggers the change of animation at various specific times.
using UnityEngine;
using System;
public class Sequencer: MonoBehaviour
{
//Basic flags to indicate actions required by this class
private bool m_StartPlayed;
private bool m_FirstPlayed;
private bool m_SecondPlayed;
private bool m_ThirdPlayed;
private bool m_EnderPlayed;
private float m_TimeIntervalAccum;
void Start()
{
m_StartPlayed = false;
m_FirstPlayed = false;
m_SecondPlayed = false;
m_ThirdPlayed = false;
m_EnderPlayed = false;
m_TimeIntervalAccum = 0.0f;
animation.wrapMode = WrapMode.Loop;
animation.Stop();
}
void Update()
{
m_TimeIntervalAccum += Time.deltaTime;
if(m_TimeIntervalAccum > 1.0f)
{
//Perform interval tasks in Update(). This one call WorkOut every 1 sec
//WorkOut();
m_TimeIntervalAccum = 0.0f;
}
if(Time.time > 0.0 && Time.time 4.0 && Time.time ] 30.0 && Time.time ]] 60.0 && Time.time 63.0)
{
if(m_EnderPlayed == false)
{
animation.CrossFade("Idle_A3_ShiftLeft", 1.0);
m_EnderPlayed = true;
}
}
}
}
The above code works as a series of animation cross-fade calls occuring once at a particular time each. I would call it "pulse events" because I am not sure about the correct technical terms. The above implementation looks really amateurish and inflexible as I would need as many bool as number of pulse events. Is there a better way to implement this? I tried looking for information on actual C# delegates and events on google but can't find one specific to what I have shown here.
Since the question is already answered I'd just like to point out that m_TimeIntervalAccum = 0.0f; should be m_TimeIntervalAccum--; for your function to be run on average once a second. Your way it would always be called after little over a second, which can of course accumulate. ;)
Since you already know the amount of time you need between each animation, I would use a coroutine:
http://unity3d.com/support/documentation/ScriptReference/index.Coroutines_26_Yield.html
public class example : MonoBehaviour
{
IEnumerator Do()
{
print("Do now");
yield return new WaitForSeconds(2);
print("Do 2 seconds later");
}
IEnumerator Awake()
{
yield return StartCoroutine("Do");
print("Also after 2 seconds");
print("This is after the Do coroutine has finished execution");
}
}
Thanks for the quick reply! The link you have shown really explain the things I need in details. I totally overlook that when reading the manual. By the way, what does the return type IEnumerator means?
please use more specific titles for your questions in the future.
I have updated the question title so it should be clearer now.
