May not work if basic updates have not been installed. Windows XP is not supported. Let me know if you find a mainstream, recent distro that has issues. Try Unity Other Platforms ZFBrowser is only supported on the platforms listed above right now. Scripting You can send and receive messages from the currently loaded browser page.
You can call functions in the page by invoking CallFunction : using ZenFulcrum. Done ; Functions are resolved in the global scope of the top frame of the browser and executed with the given arguments. Done ; To query the page for data, you can look at the return value. EvalJS and CallFunction don't execute immediately, they are asynchronous, therefore they return promises: browser.
EvalJS "document. Done ; browser. CallFunction "doSomeFoo" , 1 , 2 , 3. ToWaitFor ; Debug. Value ; This can be much easier to deal with in cases where you are chaining a lot of tasks. See the promise section for more details on the promise library. Do this with RegisterFunction : browser. This is a class which implicitly converts to basic types like strings and integers. If you'd like to pass something yet still more complex, or have data automatically read from your objects' fields: You can use any JSON system such as Unity's functions , Json.
Json, or another library of your choice to pack and unpack data on the Unity side. You can use JSON. You can also evaluate raw JavaScript in the browser by calling browser. EvalJS If the Browser isn't ready for commands or the page isn't loaded yet, it will queue your commands and execute them then the page is loaded.
The JavaScript execution engine is V8. Not only is JavaScript support robust and complete, you can also use es6 features supported by the backing Chromium version. Note that functions you expose won't be available at the time of the HTML load event. If you need to know when the page loads, use browser.
WhenLoaded Unity side. Check out the included demo and examples for some example code and use cases. For pages that have Content Security Policies preventing use of eval "Refused to execute inline script because it violates the following Content Security Policy There's pitfalls, so read the function's documentation.
EmbeddedBrowser namespace for simplicity and to avoid potential conflicts. An UnhandledException handler for Debug. LogError is registered by default. You can use Promises with coroutines: yield return somePromise.
ToWaitFor ; waits for the promise to be rejected or resolved. You can query a Promise for its resolved value or rejection with promise. Remember: If you want to run scripts on arbitrary websites, you can open a browser to that website and inject JavaScript with browser.
If you want to customize or change how these resources are fetched, read the documentation in WebResources. In the editor, you can simply refresh a page to see updated changes for changed files. File names are case-sensitive! Test your standalone build. Under the Editor some platforms may incorrectly load wRonGcapS successfully.
When you build, all browser assets are packaged up as a single file and included with the build. Avoid putting untrusted code in BrowserAssets You may need to URL-encode your path if it contains non-alphanumeric characters. Out of the box, there are systems included for taking input from mouse, screen touches, camera ray FPS , and tracked VR controllers. These input systems support browsers that are rendered either a to a mesh of any shape with an appropriate mesh collider or b Unity's GUI system.
A few browser prefabs are included. Which one you use depends on what type of input you'd like: Have a mesh in a scene you click on with your regular mouse cursor? Use the Browser Mouse prefab. Have a character walking around in a scene that interacts with browser "screens"? Use the Browser FPS prefab along with your character controller to use a camera's forward ray to point and the mouse to click.
It calculates rays from the main or your given camera and uses a CursorRendererOverlay to render the cursor in the middle of the game view. Have a GUI of some sort? It uses a CursorRendererOS to change the mouse cursor. Consider setting the Canvas 's Pixel Perfect flag to true for a nicer-looking screen-space browser.
Want to point at the browser in VR with tracked controllers? Use the Browser VR prefab. VR needs some extra setup, keep reading here. It uses a CursorRendererWorldSpace to render the cursor in the game world.
All input handlers above except the GUI one use a mesh collider and rays to determine where on the browser you are pointing. You can customize the shape of the mesh, but make sure the collider a has the same mesh or b a substantially similar mesh with UVs that visually align. A wide variety of mouse cursors are displayed on web pages to give context. But you might be able to workaround this by using EvalJS. Mouse scroll speed and double-click handling options can be adjusted by altering myBrowserUI.
VR Input An input system is included for getting input from tracked VR controllers to point at and interact with a browser. First: If you are using Unity Incompatible with SteamVR package and reduced controller support.
It should work right out of the box for a Vive wand or Oculus Touch. Click the touchpad or joystick to middle click. Requires the SteamVR package. Open up OpenVRConfig. SteamVR's Unity plugin has assorted bugs and issues so be prepared for some hitches. Cancel the dialog repeatedly and close Unity. SteamVR Unity version 2. Apply this patch , then reopen Unity and import the ZFBrowser bindings. If you don't have any actions defined you can import the ZFBrowser actions immediately.
More: If pointing works but buttons don't then something isn't set up right. The actions named in OpenVRConfig.
PointPose and LeftClickAction are critical, the rest less so. Is the action set active? See below Are mapping defined for your controller? You don't have to use the provided actions, you can set the browser to use whatever input names you want in OpenVRConfig. You can also change, disable, or remap the inputs in this file. Default bindings are included for Vive wands and Oculus Touch.
If you have more than one action set you need to enable the Browser's actions set ui by default before browser inputs will work. Oculus VR If you are using Unity Common Once that's set up, you should be able to open up the VR demo scene and give it a try!
To get things set up in your own scene: Start by dropping a Browser VR prefab into the scene. Find the VRBrowserHand prefab and drop a couple into your scene next to your camera.
Use the inspector to assign one of them to the right hand. You can clear the visualization s if you don't want to use the default "laser pointer". It means it can take up to 8 MB if the block size is 4 MB , give or take some additional data like a checksum. Building a mapping file naively is obviously space ineffective. But this can be improved significantly. If the frame format is using non-linked blocks each block is independent - all Censys archives then the state size of the decompressor is minimal at the block boundary position.
There is no need to store the block buffers after the block reading has finished. The only size that needs to be stored is the content checksum xxHash state so decompressor can compute the checksum of all stored blocks when finished.
Size hint is a preferred size of the input archive chunk to process in the next read call so the memory allocation in the decompressor is optimal. In other words, size hint is a number of bytes to read from the input archive so the block is processed in one call.
When reading the archive in this way the file is read and processed by the whole blocks, which is the most effective way. The size hints determine block boundaries when reading the LZ4 archive by chunks.
We store the decompressor state exactly at those positions to minimize the size of the mapping file. When processing the LZ4 archive you may also find handy to store one more information to the checkpoint - position in the uncompressed data stream data produced by decompressor. This may be useful when jumping in the data stream - depends on the structure of the compressed file.
Most of the time the block boundary is not aligned with the json record separator new line in the decompressed JSON file. Thus jumping to the checkpoint resumes the reading in the middle of the JSON record. In that case your logic has to take this into account and find the next record in the uncompressed data stream to resume processing correctly.
The position in the stream may help you with the book-keeping of already processed records or to distribute the file processing among multiple workers correctly. It suffices to store just the position of the block boundary and the checksum state 48 B but this space saving is not significant and poses another complications.
In the current state each checkpoint is fully fledged state snapshot independent on each other with only small space overhead. In this post I explained the way to handle network outages and interruptions while processing large LZ4 archives. The decompressor state marshalling technique was proposed and tested in practice.
The set of decompressor checkpoints gives also the possibility to random access the LZ4 archive which was not possible before without reading the whole file from the beginning. This also enables parallel processing of large LZ4 archives saving the bandwidth and time. Processing terabyte large LZ4 files in a streaming fashion with resumption and random access.

Firefox does not support filename. Besides, the server must declare the header Access-Control-Expose-Headers: Content-Disposition in order to allow the browser to read the content-disposition header.
This mostly works. Except Apple is behind times and your regex fails on Safari. Here is an example using node-fetch for anyone that finds this.

This approach is especially useful for downloading, via a stream, big-sized files that are dynamically generated on the server side. Yuci Yuci 20k 5 5 gold badges 91 91 silver badges bronze badges. When I execute the line 'downloadLink.
Any reason for that? If I comment the 'downloadLink. Any ideas? This attribute instructs browsers to download a URL instead of navigating to it, so the user will be prompted to save it as a local file. This attribute only works for same-origin URLs. A similar but cleaner and more reliable solution IMO. On your fetch function This is a helpful solution, thanks! As written the filename value comes through twice in filename.
