Passing int values across scripts? C#

Questions & Answers
1

Long time no see UnityAnswers.

So I have a script that calls functions at set times, that works fine. What I want to happen is once that function is called it feeds int values into other scripts however I can’t work out what the right syntax. On an empty object I have “levelControl.cs” that I type in the int values I want to pass on to the 2nd script “WallSection.cs” attached to a gameObject called “WallSpawnPoint”

So in the “levelControl” script I have this…

	void GroupNumber0()
	{
	//Talk too WallSection. and set NumberOfWalls to 10
	GameObject.Find ("WallSpawnPoint").GetComponent<WallSection>().SetNumberOfWalls();
	}

And on my “WallSection” script I have…

	public void SetNumberOfWalls(int NewNumber)
	{
		NewNumber = NumberOfWalls;
	}

I’ve never been able to work out how to feed an int from one script into another as you can see despite checking numerous tutorials. Bizarrely I understand how to pass a Vector3 but not a simple int.

So ultimately, I want to set the “NumberOfWalls” int in the script “WallSection.cs” via the script “levelControl.cs”

What’s the correct syntax and correct usage of the function brackets? Any help is appreciated!

void GroupNumber0()
{
GameObject.Find (“WallSpawnPoint”).GetComponent().SetNumberOfWalls(10); //pass 10 into the SetNumberOfWalls parameter
}

 public void SetNumberOfWalls(int NewNumber)
    {
        NumberOfWalls = NewNumber; //you had these reversed: you want to set NumberOfWalls to NewNumber, not the other way around
    }

Alternatively, you could even say:

void GroupNumber0()
    {
    GameObject.Find ("WallSpawnPoint").GetComponent<WallSection>().NumberOfWalls = 10;
    }
