Is it possible to call a method which has optional arguments with Invoke?
void Start()
{
this.GenerateLevel(true);
}
private void GenerateLevel(bool isFirst = false)
{
if (isFirst || this.IsTimeToGenerate())
{
this.currentLevel = Instantiate(Levels[Random.Range(0, this.Levels.Length)], this.GetNewPosition(isFirst), Quaternion.identity) as GameObject;
this.currentLevel.transform.parent = this.transform;
this.previousLevel = this.currentLevel;
}
Invoke("GenerateLevel", 0.5f);
}
Is this code executable?
No, you are trying to invoke GenerateLevel(float) when you have GenerateLevel(bool). If you defined a second method GenerateLevel(float) then it would valid.
I don't try to invoke generateLevel with float. 0.5f (the second parameter I put in invoke) is for the time I want it to be executed
@deadliness Correct, at work and mixed up Invoke and StartCoroutine in my head.

No, you cannot use Invoke with methods that have parameters (optional or required), but you can still use coroutine that is more elegant in your case:
void Start ()
{
StartCoroutine(GenerateLevel(true));
}
IEnumerator GenerateLevel(bool isFirst = false)
{
while (true)
{
if (isFirst || this.IsTimeToGenerate())
{
this.currentLevel = Instantiate(Levels[Random.Range(0, this.Levels.Length)], this.GetNewPosition(isFirst), Quaternion.identity) as GameObject;
this.currentLevel.transform.parent = this.transform;
this.previousLevel = this.currentLevel;
}
yield return new WaitForSeconds(0.5f);
}
}
Well, you don't really use isFirst in a meaningful way in this example since it won't change during the execution of the coroutine. This one would make more sense:
IEnumerator GenerateLevel()
{
while (true)
{
this.currentLevel = Instantiate(Levels[Random.Range(0, this.Levels.Length)], this.GetNewPosition(isFirst), Quaternion.identity) as GameObject;
this.currentLevel.transform.parent = this.transform;
this.previousLevel = this.currentLevel;
yield return null; // Just for safety in case "IsTimeToGenerate" never returns false in which case you wouldn't yield at all which would actually freeze the application.
while (!IsTimeToGenerate())
yield return new WaitForSeconds(0.5f);
}
}
