<!-- ABOUT THE PROJECT -->
## About The Project
<a href="https://github.com/praydog/UEVR">Universal Unreal Engine VR mod (UEVR)</a> by [Praydog](https://www.patreon.com/praydog) allows you to play any Unreal Engine 4.8-5.2 game in VR. Thing is setting it up for successful injection is bit convoluted and tricky for non technical users.

Chihuahua aims to solve this, making whole process as easy as dragging and dropping game `.exe` on chihuahua executable. All hard decisions will be handled for you.

<!-- GETTING STARTED -->
## Getting Started

This is an example of how you may start your first UEVR game.

For highest chance of success pick one of 'works perfectly' titles with good user opinion. To check all that take a look at [Flat2VR Discord](https://discord.com/invite/ZFSCSDe), `#ue-games` channel.
Also keep in mind that we're going to use VR technology called OpenXR which means chihuahua type of injection will work best on Quest 2/3/Pro and Pico 4 over Virtual Desktop.

Other streaming software and HMDs may be compatible but that is currently untested.

### Prerequisites

#### Antivirus exception

Make folder on your PC and add its location to your antivirus exceptions. The way [UEVR mod](https://github.com/praydog/UEVR) works triggers false positives with antivirus software.
It's up to you to decide if making an exception or pausing antivirus to play a game is ok. Feel free to review all source code here and in [UEVR repo](https://github.com/praydog/UEVR).

#### Download Chihuahua

Latest release is [here](https://github.com/keton/chihuahua/releases/latest/download/chihuahua.zip). You browser/antivirus may need some reassuring for the download to happen. Unpack contents to the folder you've added to antivirus exceptions.

### Basic Usage --> 'I don't know what I'm doing' mode
1. pick a 'works perfectly' game. Especially for the first run goal is to verify UEVR works on your setup
2. go to your games launcher i.e. Steam or Epic
3. use 'browse game files' option to open game installation folder and find game executable
4. open folder you've unpacked chihuahua in another window next to it
5. put on your headset and start Virtual Desktop session
6. drag game executable with your mouse and drop it on top of chihuahua.exe
7. your game should start
8. after 15 seconds [UEVR mod](https://github.com/praydog/UEVR) will start and your headset movement will start affecting game camera. It's strongly suggested to click trough intro cinematics and get to the menu or load game as some games don't like being injected on early boot.
9. if it worked - congratulations. Follow official [UEVR docs](https://praydog.github.io/uevr-docs/index.html) to get the most of the mod.
10. if it did not - close the game, there should be a console window waiting with log that indicates what went wrong.

<!-- USAGE EXAMPLES -->
## Usage

### Drag and drop game.exe on top of chihuahua.exe

See 'Basic usage' above

### Commandline program

Chihuahua is a well behaved console application. Double click `chihuahua.exe` for up to date list of options.

Keep in mind that you can make a desktop shortcut to `chihuahua.exe`, go to shortcut properties
and add full path to game executable in double quotes as a parameter. This will make shortcut to launch and inject the game.

### Rai Pal integration (in progress)

[Rai Pal](https://github.com/raicuparta/rai-pal) is an amazing game launcher by [Raicuparta](https://raicuparta.com/).

You can integrate Chihuahua by unpacking it to `%APPDATA%\raicuparta\rai-pal\data\mod-loaders\runnable\mods\chihuahua`.
Then after starting Rai Pal and clicking on installed game there will be new Chihuahua launch button.
