How do I make Unity save output pngs to a relative path instead of absolute?

Question

I want my game to save a png. Using the answer here I can do that, but how/where do I save them to a path relative to the game and not specific to my computer?

Is there a path similar to how PlayerPrefs are saved such that I don't need to know or specify where they are saved, but the OS and Unity know where to create them?

Answer 1

You can try using one of the built in path strings provided by Unity (check the sample below) and generate a path that is relative to one of those locations.

• Application.dataPath
  
• Application.persistentDataPath
  
• Application.streamingAssetsPath
  
• Application.temporaryCachePath
  

Usage example

using System;
using System.IO;
using UnityEngine;

public class TestScript : MonoBehaviour
{
    private void Start()
    {
        string path = GetTemporaryImagePath();

        // Code to save an image at "path"
        // ...
    }

    private string GetTemporaryImagePath()
    {
        return Path.Combine(Application.temporaryCachePath, $"{Guid.NewGuid()}.png");
    }
}
