I made a word game app for android in Unity, where the player has to find a word from a category previously loaded to the game.
The way I load the categories is:
There is a folder named Categories, inside Assets, I run through the folder and read each text file as a category.
The categories are stored in a dictionary where the key is name the of the file and the value is every line of the file as an array element.
It worked well on the PC however no luck on android. Tried changing the path to
"public string categoriesDirectoryPath = Application.persistentDataPath +"Categories";" still does not work.
Original path was "Assets/Categories"
Code for initiating the dictionary with the file values is (Happens on GameManager's Awake()):
private Dictionary<string, string[]> createCategories(string directoryPath)
{
Dictionary<string, string[]> categories = new Dictionary<string, string[]>();
string[] categoryPaths = Directory.GetFiles(directoryPath);
foreach (string path in categoryPaths)
{
if (!path.EndsWith("meta")) {
Debug.Log(path);
string categoryName = Path.GetFileNameWithoutExtension(path);
Debug.Log(categoryName);
string[] categoryData = File.ReadAllLines(path).ToArray();
categories.Add(categoryName, categoryData);
}
}
return categories;
}
Is there a way of iterating the folder and reading the text files that were in Assets/Categories after building the APK?

No.
If you want to access from the project, in a build, you have two options:
1.Put the file a folder named "Resources" then use the Resources to read the file and copy it to the Application.persistentDataPath path. By copying it to Application.persistentDataPath, you'll be able to modify it. Anything in the "Resources" is read only.
2.Put the file in the StreamingAssets folder then use UnityWebRequest, WWW or the System.IO.File API to read it. Atfer this, you can copy it to the Application.persistentDataPath.
Here is a post with code examples on how to do both of these.
3.AssetBundle(Recommended due to performance and loading reaons).
You can build the file as AssetBundle then put them in the StreamingAssets folder and use the AssetBundle API to read it.
Here is a complete example for building and reading AssetBundle data.
Octokit allows me to easily retrieve the list of files in a given folder like so:
var directoryContent = await _githubClient.Repository.Content.GetAllContents("MyUsername", "MyProject", "TheFolderName").ConfigureAwait(false);
Unfortunately, the Content property for each file is null which means that I have to loop through the list of files and retrieve each one separately like so:
foreach (var file in directoryContent)
{
var fileWithContent = await _githubClient.Repository.Content.GetAllContents("MyUsername", "MyProject", file.Path).ConfigureAwait(false);
... do something with the content ...
}
Is there a more efficient way to get the content of all files in a given folder?
Just for reference: This is on purpose. If you read a whole directory and load all the content in one step it's huge load. So, the first call skips the content (Content property is null). The second step requests just this file and then the content is present.
Only thing I'm still missing is a method that can return just one result instead of a list if I pull a single file.
I just want to have 2 Objects from Type "Media". Therefore i have 2 .mp3 files.
The first is no problem, i can play it.
But if i enable the Code for the second file, the System throws an Error
"InvocationtargetException" it says "System can not find the file"
I checked both paths of the .mp3 files, here are the results:
file:/C:/Users/Lennie-Admin/Documents/NetBeansProjects/Lost/Rise.mp3
file:/C:/Users/Lennie-Admin/Documents/NetBeansProjects/Lost/TrueStrength.mp3
I checked my working directory with System.out.println( new File("").getAbsolutePath()); the Result is
C:\Users\Lennie-Admin\Documents\NetBeansProjects\Lost
And finally here is the java Code, which should create the 2 Objects:
String uriString1 = new File("Rise.mp3").toURI().toString();
Media hit1 = new Media(uriString1);
String uriString2 = new File("TrueStrength.mp3").toURI().toString();
Media hit2 = new Media(uriString2);
Hope you can help me :)
In my application ,I have stored uploaded images to folder ./assets/uploads. I am using easyimage and imagemagick for storing the images.
In my application, after uploading the images, it should show the new uploaded image. But it is not displayed even if the page is refreshed. But when i do sails lift , the image is shown.
How to show image immediately after uploading the image? Thanks a lot!
It's a totally normal situation, because of the way Sails works with the assets.
The thing is that upon sails lift the assets are being copied (including directory structure and symlinks) from ./assets folder to ./.tmp/public, which becomes publicly accessible.
So, in order to show your images immediately after upload, you, basically, need to upload them not to ./assets/uploads but to ./.tmp/public/uploads.
The only problem now is that the ./.tmp folder is being rewritten each time your application restarts, and storing uploads in ./tmp/... would make them erased after every sails lift. The solution here would be storing uploads in, for example, ./uploads and having a symlink ./assets/uploads pointing to ../uploads.
Though this question is pretty old but I would like to add a solution which I just implemented.
Today I spend almost 4 hours trying all those solutions out there. But none helped. I hope this solution will save someone else's time.
WHY images are not available immediately after uploading to any custom directory?
Because according to the default Sails setup, you can not access assets directly from the assets directory. Instead you have to access the existing assets that is brought to .tmp/public directory by Grunt at time of sails lift ing
THE Problems
(Available but Volatile) If you upload a file (say image) anywhere inside .tmp/public
directory, your file (image) is going to erase at next sails lift
(Unavailability) If you upload a file in any other custom directory- say: ./assets/images, the uploaded file will not be available immediately but at next sails lift it will be available. Which doesn't makes sense because - cant restart server each time files gets uploaded in production.
MY SOLUTION (say I want to upload my images in ./assets/images dir)
Upload the file say image.ext in ./tmp/public/images/image.ext (available and volatile)
On upload completion make a copy of the file image.ext to ./assets/images/*file.ext (future-proof)
CODE
var uploadToDir = '../public/images';
req.file("incoming_file").upload({
saveAs:function(file, cb) {
cb(null,uploadToDir+'/'+file.filename);
}
},function whenDone(err,files){
if (err) return res.serverError(err);
if( files.length > 0 ){
var ImagesDirArr = __dirname.split('/'); // path to this controller
ImagesDirArr.pop();
ImagesDirArr.pop();
var path = ImagesDirArr.join('/'); // path to root of the project
var _src = files[0].fd // path of the uploaded file
// the destination path
var _dest = path+'/assets/images/'+files[0].filename
// not preferred but fastest way of copying file
fs.createReadStream(_src).pipe(fs.createWriteStream(_dest));
return res.json({msg:"File saved", data: files});
}
});
I dont like this solution at all but yet it saved more of my time and it works perfectly in both dev and prod ENV.
Thanks
Sails uses grunt to handle asset syncing. By default, the grunt-watch task ignores empty folders, but as long as there's at least one file in a folder, it will always sync it. So the quickest solution here, if you're intent on using the default static middleware to server your uploaded files, is to just make sure there's always at least one file in your assets/uploads folder when you do sails lift. As long as that's the case, the uploads folder will always be synced to your .tmp/public folder, and anything that's uploaded to it subsequently will be automatically copied over and available immediately.
Of course, this will cause all of your uploaded files to be copied into .tmp/public every time your lift Sails, which you probably don't want. To solve this, you can use the symlink trick #bredikhin posted in his answer.
Try to do this:
npm install grunt-sync --save-dev --save-exact
uncomment the line: // grunt.loadNpmTasks('grunt-sync');
usually it is near to the end of the file /tasks/config/sync.js.
lift the App again
Back to the Original answer
I was using node version 10.15.0, and I faced same problem. I solved this by updating to current version of node(12.4.0) and also updated npm and all the node modules. After this, I fixed the vulnerabilities(just run 'npm audit fix') and the grunt error that was coming while uploading the images to assets/images folder was fixed.
Try out this implementation
create a helper to sync the file
example of the filesync helper
// import in file
const fs = require('fs')
module.exports = {
friendlyName: 'Upload sync',
description: '',
inputs: {
filename:{
type:'string'
}
},
exits: {
success: {
description: 'All done.',
},
},
fn: async function ({
filename
}) {
var uploadLocation = sails.config.custom.profilePicDirectory + filename;
var tempLocation = sails.config.custom.tempProfilePicDirectory + filename;
//Copy the file to the temp folder so that it becomes available immediately
await fs.createReadStream(uploadLocation).pipe(fs.createWriteStream(tempLocation));
// TODO
return;
}
};
now call this helper to sync your files to the .temp folder
const fileName = result[0].fd.split("\\").reverse()[0];
//Sync to the .temp folder
await await sails.helpers.uploadSync(fileName);
reference to save in env
profilePicDirectory:path.join(path.resolve(),"assets/images/uploads/profilePictures/")
tempProfilePicDirectory:path.join(path.resolve(),".tmp/public/images/uploads/profilePictures/"),
also can try
process.cwd()+filepath
I have a file reader channel picking up an xml document. By default, a file reader channel populates the 'originalFilename' in the channel map, which ony gives me the name of the file, not the full path. Is there any way to get the full path, withouth having to hard code something?
You can get any of the Source reader properties like this:
var sourceFolder = Packages.com.mirth.connect.server.controllers.ChannelController.getInstance().getDeployedChannelById(channelId).getSourceConnector().getProperties().getProperty('host');
I put it up in the Mirth forums with a list of the other properties you can access
http://www.mirthcorp.com/community/forums/showthread.php?t=2210
You could put the directory in a channel deploy script:
globalChannelMap.put("pickupDirectory", "/Mirth/inbox");
then use that map in both your source connector:
${pickupDirectory}
and in another channel script:
function getFileLastModified(fileName) {
var directory = globalChannelMap.get("pickupDirectory").toString();
var fullPath = directory + "/" + fileName;
var file = Packages.java.io.File(fullPath);
var formatter = new Packages.java.text.SimpleDateFormat("yyyyMMddhhmmss");
formatter.setTimeZone(Packages.java.util.TimeZone.getTimeZone("UTC"));
return formatter.format(file.lastModified());
};
Unfortunately, there is no variable or method for retrieving the file's full path. Of course, you probably already know the path, since you would have had to provide it in the Directory field. I experimented with using the preprocessor to store the path in a channel variable, but the Directory field is unable to reference variables. Thus, you're stuck having to hard code the full path everywhere you need it.
