[JS] How convert a String[] to int[]
Hello
I extract data from a text file with "fileContents.Split()" into a String[] variable
But the values are only integers, I'd like to stock them into an integer Array int[]
var sr = new StreamReader("Assets/tilemap_layer_1.txt");
var fileContents = sr.ReadToEnd();
sr.Close();
tileMap = fileContents.Split(","[0]);
If I declare tileMap like this : "var tileMap : int[];" it doesn't work, I get "BCE0022: Cannot convert 'String[]' to 'int[]'."
How I could convert tileMap into an integer array ? Is it possible ? String array is too slow
Thank you
Well, first of all, I'd recomend you used data collections like Lists for that. They're generics, so you'll have to import them into your script. So lets do something like this:
import System.Collections.Generic;
function readFile() : List.<int> {
//first read the contents
var sr = new StreamReader("Assets/tilemap_layer_1.txt");
var fileContents = sr.ReadToEnd();
sr.Close();
//split it
var tileMap : String[] = fileContents.Split(","[0]);
//now we create our List
var mapList : List.<int> = new List.<int>();
//now we cycle through the entire content of tileMap
for(var ctt : String in tileMap) {
mapList.Add(ctt.ToInt32()); //don't forget to convert the string to int
}
return mapList; //return content
}
And there you go! (Note, I wrote the code directly here, so it might have some errors).
Awesome !
Thank you very much it works very well :)
I just had to change mapList.Add(ctt.ToInt32()); to mapList.Add(int.Parse(ctt)); I hope it works as fast
