How to set a line of code to be a variable

Questions & Answers
1

I have a line that of code that i use over and over several times in different ways

GameObject.Find("colorswitchred (" + id.ToString() + ")").transform.GetComponent<Main>().state

such as:

        if (GameObject.Find("colorswitchred (" + id.ToString() + ")").transform.GetComponent<Main>().state < 3)
        {
            GameObject.Find("colorswitchred (" + id.ToString() + ")").transform.GetComponent<Main>().state ++;
        }
        else
        {
            GameObject.Find("colorswitchred (" + id.ToString() + ")").transform.GetComponent<Main>().state = 1;
        }

Is there a way I can set a string or something to be this line of code, that way I can just do like

if (tile < 3)
{
     tile ++;
}
else
{
    tile = 1;
}

Also known as a “function”:

private Main FindSwitch( int id)
{
	// Return the component following this sort of search (I'm assuming this is an integer)
	return  GameObject.Find("colorswitchred (" + id.ToString() + ")").transform.GetComponent<Main>();
}

Then your code might become:

Main switchMain = FindSwitch(id:);

if (switchMain.state < 3)
{
	switchMain.state ++;
}
else
{
	switchMain.state = 1;
}
