# AnotherFileBrowser Just another File Dialog for Unity, with easy implementation. Using Ookii Dialogs. Rather than putting everything in .dll, i've done this simply with a class, so you can extend it based on Ookii Dialogs.  # Getting Started Open Package Manager in Unity and Click on Plus Icon -> Add package from git URL, paste following link `https://github.com/SrejonKhan/AnotherFileBrowser.git` and click Add. After importing, change **Change API Compatibility Level** to **_.NET 4.x_**, from `Project Settings -> Player -> Other Settings`. And, change **Scripting Backend** to **_Mono_**. For example, go to `Packages -> Another File Browser -> Example` in Project View, then import `Example.unitypackage`. # Implementation Implementation is quite easy, but before implementing let's know about **BrowserProperties** constructor. **BrowserProperties** ```csharp public class BrowserProperties { public string title; //Title of the Dialog public string initialDir; //Where dialog will be opened initially public string filter; //aka File Extension for filtering files public int filterIndex; //Index of filter, if there is multiple filter. Default is 0. public bool restoreDirectory = true; //Restore to last return directory public BrowserProperties() { } public BrowserProperties(string title) { this.title = title; } } ``` Make sure to define `AnotherFileBrowser.Windows` namespace. ### Picking a Single File ```csharp var bp = new BrowserProperties(); bp.filter = "txt files (*.txt)|*.txt|All Files (*.*)|*.*"; bp.filterIndex = 0; new FileBrowser().OpenFileBrowser(bp, path => { //Do something with path(string) Debug.Log(path); }); ``` ### Picking Multiple File(s) ```csharp var bp = new BrowserProperties(); bp.filter = "txt files (*.txt)|*.txt|All Files (*.*)|*.*"; bp.filterIndex = 0; new FileBrowser().OpenMultiSelectFileBrowser(bp, path => { //Do something with path(string[]) string s = ""; for (int i = 0; i < path.Length; i++) { s += path[i] + "\n"; } }); ``` ### Picking Folder Path ```csharp var bp = new BrowserProperties(); bp.filter = "txt files (*.txt)|*.txt|All Files (*.*)|*.*"; bp.filterIndex = 0; new FileBrowser().OpenFolderBrowser(bp, path => { //Do something with path(string) Debug.Log(path); }); ``` ### Picking Path for Saving File ```csharp var bp = new BrowserProperties(); bp.filter = "txt files (*.txt)|*.txt"; bp.filterIndex = 0; new FileBrowser().SaveFileBrowser(bp, "test", ".txt", path => { //Do something with path(string) Debug.Log(path); }); ``` ### Picking and Loading Image ```csharp var bp = new BrowserProperties(); bp.filter = "Image files (*.jpg, *.jpeg, *.jpe, *.jfif, *.png) | *.jpg; *.jpeg; *.jpe; *.jfif; *.png"; bp.filterIndex = 0; new FileBrowser().OpenFileBrowser(bp, path => { //Load image from local path with UWR StartCoroutine(LoadImage(path)); }); //Load Image from Local IEnumerator LoadImage(string path) { using (UnityWebRequest uwr = UnityWebRequestTexture.GetTexture(path)) { yield return uwr.SendWebRequest(); if (uwr.isNetworkError || uwr.isHttpError) { Debug.Log(uwr.error); } else { var uwrTexture = DownloadHandlerTexture.GetContent(uwr); //placeholderImage is an Image Component of Unity UI placeholderImage.sprite = Sprite.Create(uwrTexture, new Rect(0, 0, uwrTexture.width, uwrTexture.height), new Vector2(0, 0)); } } } ``` #### Pro-Tips Use preprocessor for [Platform Dependent Compilation](https://docs.unity3d.com/Manual/PlatformDependentCompilation.html), so there won't be any issue while building for other platforms. #### IL2CPP Support I'm facing crashes if try to open dialog from il2cpp build. If you want to try in il2cpp, you need to add `Mono.Posix` & `Mono.WebBrowser` from `C:\Program Files\Unity\Editor\Data\MonoBleedingEdge\lib\mono\gac` to `\Plugins` folder. There must be a workaround, you can check crash logs after crash. I will try to fix it, if you already fixed it, open a PR, it would be highly appreciated. # Android / iOS Support This is only for Windows. You can check out [UnityNativeFilePicker](https://github.com/yasirkula/UnityNativeFilePicker) by Yasirkula. There are plenty of native plugins, but this one support iOS too. # Contacts ### Srejon Khan Indie Game Programmer **Mail:** srejonkhan9@gmail.com
