Convert string variable into floats?

print(restoreplayerpos);
// variable contains -7.4, 1.4, 6.5

// restore player position
var playerObject = GameObject.Find("player");
playerObject.transform.position = Vector3(restoreplayerpos); // need to convert the variable restoreplayerpos into a float somehow?

You can use string.Split() for splitting the string values and float.Parse() for string to float conversion.

float.Parse() works even if the input string contains whitespaces. So " 1.4" will be converted without any errors.

Try this:

Javascript

var sStrings = restoreplayerpos.Split(","[0]);

var x : float = float.Parse(sStrings[0]);
var y : float = float.Parse(sStrings[1]);
var z : float = float.Parse(sStrings[2]);

var playerObject = gameObject.Find("player");
playerObject.transform.position = new Vector3(x, y, z);

C#

var sStrings = restoreplayerpos.Split(","[0]);

float x = float.Parse(sStrings[0]);
float y = float.Parse(sStrings[1]);
float z = float.Parse(sStrings[2]);

var playerObject = GameObject.Find("player");
playerObject.transform.position = new Vector3(x, y, z);

your answer is much cleaner then mine ^^ I totally forgot about Split.

Thank you both. I'll try this when I'm able to this evening and see how it goes. Much appreciated as always.

Your answer would get closer to perfect with a try/catch section.

Thank you keburanuil. That has worked brilliantly. Thanks to everyone else too, have chosen keburanuil's answer as it seemed the most efficient.

string TheString = { “-7.4”, “1.4”, “6.5” };
float VectorPosition = new float[TheString.Length];
Vector3 restoreplayerpos = new Vector3();

                  for (int i = 0; i < TheString.Length;i++ )
                  {
        
                     VectorPosition _= float.Parse(TheString*);*_

restoreplayerpos.x = VectorPosition[0];
restoreplayerpos.y = VectorPosition[1];
restoreplayerpos.z = VectorPosition[2];
}

var playerObject = GameObject.Find(“player”);

playerObject.transform.position = new Vector3( restoreplayerpos.x, restoreplayerpos.y,restoreplayerpos.z);
why do you need it to be a string ??
I didn’t test it but It should work.
