Parsing to int64 or larger number value

Unity Engine
1

Hey guys, I ran into a problem;
Format Exception: Input string was not in the correct format
FormatException: Input string was not in the correct format
System.Int32.Parse (System.String s) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System/Int32.cs:629)

I am using a fairly simple save/load function that ‘encrypts’ and decodes a code to load a ship Not exactly sure what the problem is but I am fairly sure that int just doesn’t support a high enough value.

Just not sure how to fix it

I dont have any idea of a more efficient encryption as it has the bare minimum details
‘BlockId(x,y,z(x,y,z|’

        public string ship;
    }
    //id,position(xyz),rotation(xyz)
    public string shipString = "x(0,0,0(0,0,0|";

    public void saveBuild(){
        BinaryFormatter bf = new BinaryFormatter ();
        FileStream file = File.Create (Application.persistentDataPath + "/shipBuilds.dat");

        shipStringc data = new shipStringc ();
        data.ship = shipString;

        bf.Serialize (file, data);

                string[] sector = s.Split ('(');
                string[] vectors = sector[1].Split (',');
                string[] quaters = sector[2].Split (',');
                if (sector [0] != "x") {
                    GameObject block = Instantiate (this.transform.GetComponent<BlockList> ().Blocks [int.Parse (sector [0])].BlockObj,
                        new Vector3 ((int.Parse (vectors [0])), (int.Parse (vectors [1])), (int.Parse (vectors [2]))),

                } else {
                 
                }
                }
            }
        }

Did you try to debug log the value of your shipstring? Are you sure you’re not saving floats in a string there?

3

The save and load works until i get over ~10 blocks then it spits the error. And yes, it only uses numbers when decrypting the rest is strings

4

Int’s are 32 bits hence the Int32 type shown in the error. Try Int64.Parse() which is a Long in C# or just type long.Parse() which does the same thing.

5

Says the same thing, just Int64 instead

6

I don’t think length is an issue anyway, the only time i use ints is at the very last stage which should only be 1-5 characters
Edit-- Yep i did a debug log and they are only 1 digit

7

Not sure how it’s working up to around 10.
Some other options could be : store the floats in the class & reconstruct your position + rotation.
Either with binaryformatter or JSonUtility.

Ah! found the problem. Turned out it had nothing to do with lengthy values. I have a ‘clear’ button that removed everything on the canvas and it turns out when I press clear i forgot to reset shipString.

Thanks everyone for the help.

:slight_smile: Glad it’s working/fixed.
