## Running
Project Lighthouse requires a MySQL database. For Linux users running docker, one can be set up using
the `docker-compose.yml` file in the root of the project folder.
Next, make sure the `LIGHTHOUSE_DB_CONNECTION_STRING` environment variable is set correctly. By default, it
is `server=127.0.0.1;uid=root;pwd=lighthouse;database=lighthouse`. If you are running the database via the
above `docker-compose.yml` you shouldn't need to change this. For other development/especially production environments
you will need to change this.
Once you've gotten MySQL running you can run Lighthouse. It will take care of the rest.

PS3 is difficult to set up, so I will be going over how to set up RPCS3 instead. A guide will be coming for PS3 closer
to release. You can also follow this guide if you want to learn how to modify your EBOOT.
There are also community-provided guides in [the official LBP Union Discord](https://www.lbpunion.com/discord), which
you can follow at your own discretion.
*Note: This requires a modified copy of RPCS3. You can find a working
version [on our GitHub](https://github.com/LBPUnion/rpcs3).*
Start by getting a copy of LittleBigPlanet 1/2 installed. (Check the LittleBigPlanet 1 section, since you'll need to do
extra steps for your game to not crash upon entering pod computer). It can be digital (NPUA80472/NPUA80662) or disc (
BCUS98148/BCUS98245). For those that don't, the [RPCS3 Quickstart Guide](https://rpcs3.net/quickstart) should cover it.
Next, download [UnionPatcher](https://github.com/LBPUnion/UnionPatcher/). Binaries can be found by reading the README.md
file.
You should have everything you need now, so open up RPCS3 and go to Utilities -> Decrypt PS3 Binaries. Point this
to `rpcs3/dev_hdd0/game/(title id)/USRDIR/EBOOT.BIN`. You can grab your title id by right clicking the game in RPCS3 and
clicking Copy Info -> Copy Serial.
This should give you a file named `EBOOT.elf` in the same folder. Next, fire up UnionPatcher (making sure to select the
correct project to start, e.g. on Mac launch `UnionPatcher.Gui.MacOS`.)
Now that you have your decrypted eboot, open UnionPatcher and select the `EBOOT.elf` you got earlier in the top box,
enter `http://localhost:10060/LITTLEBIGPLANETPS3_XML` in the second, and the output filename in the third. For this
guide I'll use `EBOOTlocalhost.elf`.
Now, copy the `EBOOTlocalhost.elf` file to where you got your `EBOOT.elf` file from, and you're now good to go.
To launch the game with the patched EBOOT, open up RPCS3, go to File, Boot SELF/ELF, and open up `EBOOTlocalhost.elf`.
Assuming you are running the patched version of RPCS3, you patched the file correctly, the database is migrated, and
Lighthouse is running, the game should now connect.
### LittleBigPlanet 1
For LittleBigPlanet 1 to work with RPCS3, follow the steps above normally.
First, open your favourite hex editor. We recommend [HxD](https://mh-nexus.de/en/hxd/).
Once you have a hex editor open, open your `EBOOTlocalhost.elf` file and search for the hex
values `73 63 65 4E 70 43 6F 6D 6D 65 72 63 65 32`. In HxD, this would be done by clicking on Search -> Replace,
clicking on the `Hex-values` tab, and entering the hex there.
Then, you can zero it out by replacing it with `00 00 00 00 00 00 00 00 00 00 00 00 00 00`.
What this does is remove all the references to the sceNpCommerce2 function. The function is used for purchasing DLC,
which is impossible on Lighthouse. The reason why it must be patched out is because RPCS3 doesn't support the function
at this moment.
Then save the file, and your LBP1 EBOOT can now be used with RPCS3.
Finally, take a break. Chances are that took a while.
## Contributing Tips
### Database migrations
Some modifications may require updates to the database schema. You can automatically create a migration file by:
1. Making sure the tools are installed. You can do this by running `dotnet tool restore`.
2. Making sure `LIGHTHOUSE_DB_CONNECTION_STRING` is set correctly. See the `Running` section for more details.
3. Modifying the database schema via the C# portion of the code. Do not modify the actual SQL database.
4. Running `dotnet ef migrations add <NameOfMigrationInPascalCase> --project ProjectLighthouse`.
This process will create a migration file from the changes made in the C# code.
The new migrations will automatically be applied upon starting Lighthouse.
### Running tests
You can run tests either through your IDE or by running `dotnet tests`.
Keep in mind while running database tests (which most tests are) you need to have `LIGHTHOUSE_DB_CONNECTION_STRING` set.
### Continuous Integration (CI) Tips
- You can skip CI runs for a commit if you specify `[skip ci]` at the beginning of the commit name. This is useful for
formatting changes, etc.
- When creating your first pull request, CI will not run initially. A team member will have to approve you for use of
running CI on a pull request. This is because of GitHub policy.
