Unity3D Stop counter - unity3d

Question

I made a script for a game that counts the playtime. So the question is how can i stop the script befor the game is over or for example save the time as a float.
// Für die SpielZeit
SpielZeit += Time.deltaTime;
// SpielZeitText = Spielzeit in einen String + "Sekunden"
SpielZeitText.text = " " + Mathf.Round(SpielZeit).ToString() + " " + "Sekunden";
// SpielZeitFuerEscape = Spielzeit in einen String + "Sekunden" (für den escape canvas)
SpielZeitFuerEscape.text = " " + Mathf.Round(SpielZeit).ToString() + " " + "Sekunden";

Answer 1

SpielZeit, SpielZeitText, and SpielZietFuerEscape should be put as members of the main class. Or you should set it accessible to anything which needs it.
Then put the counter in an Update function. (If you want to make a frame-by-frame update, include the .text setters there as well.) Enclose the counter with an if statement, which sees if you want to continue it, or if you want to stop it.
if(go_on) { //if the counter should keep going
// Für die SpielZeit
SpielZeit += Time.deltaTime;
// SpielZeitText = Spielzeit in einen String + "Sekunden"
SpielZeitText.text = " " + Mathf.Round(SpielZeit).ToString() + " " + "Sekunden";
// SpielZeitFuerEscape = Spielzeit in einen String + "Sekunden" (für den escape canvas)
SpielZeitFuerEscape.text = " " + Mathf.Round(SpielZeit).ToString() + " " + "Sekunden";
}
where go-on is a boolean, telling the code whether it should continue (true) or stop (false).
