== Software Pre-Requisites

* Git
* OpenJDK Java 17
* Gradle

== Installation

=== Download project from GitHub

```bash

$ git clone git@github.com:roborescue/rcrs-server.git
```

=== Compile the project

```bash

$ cd rcrs-server

$ ./gradlew completeBuild
```

=== Execute the Rescue Simulation Server

Open a terminal window, navigate to the ```rcrs-server``` root directory and execute

```bash

$ cd scripts

$ ./start.sh -m ../maps/test/map -c ../maps/test/config
```

== Tools

=== Map Editor

Open a terminal window, navigate to the ```rcrs-server``` root directory and execute

```bash

$ ./gradlew gmlEditor --args='<map file path>'
```
where ```--args=<map file path>``` is optional.

==== Example
```
./gradlew gmlEditor --args='maps/test/map/map.gml'
```

=== Scenario Editor

Open a terminal window, navigate to the ```rcrs-server``` root directory and execute

```bash

$ ./gradlew scenarioEditor --args='<scenario path>'
```
where ```--args=<scenario path>``` is optional.

==== Example
```
./gradlew scenarioEditor --args='maps/test/map'
```

=== Random Scenario

Open a terminal window, navigate to the ```rcrs-server``` root directory and execute

```bash

$ ./gradlew randomScenario --args="'<map path>' <options>"
```
where ```<map path>``` is the path to the map directory and ```<options>``` are the minimum and maximum value for each entity in the scenario. The ```<options>``` are optional.

==== Example
```
./gradlew randomScenario --args="'../maps/test/map' -civ 0 100 -fb 0 10 -fs 0 1 -pf 0 10 -po 0 1 -at 0 5 -ac 0 0 -refuge 0 2 -fire 0 0"
```

=== Log Viewer

Open a terminal window, navigate to the ```rcrs-server``` root directory and execute

```bash

$ ./gradlew logViewer --args="'-c' '<config file>' '<log path>'"
```
where ```<config file>``` is the path to the log viewer configuration file, default ```config/logviewer.cfg```. The ```<log path>``` is the rescue log file path, default ```logs/log/rescue.log```.

==== Example
```
./gradlew logViewer --args="'-c' 'config/logviewer.cfg' 'logs/log/rescue.log'"
```

=== `osm2gml`

Open a terminal window, navigate to the ```rcrs-server``` root directory and execute

```bash

$ ./gradlew osm2gml --args="'<osm map path>' '<gml map path>'"
```
The ```<osm map path>``` is the path to the OSM map file and the ```<gml map path>``` is the destination GML map path.

==== Example
```
./gradlew osm2gml --args="'/home/user/newmap.osm' '/home/user/newmap.gml'"
```

== Known Problems

=== Slow agent connection
If the scenario have many agents, the agents connection to the server may slow down at certain moment. To overcome this issue, you should

1. Install the `rng-tools` package
2. Edit the ` /etc/defaults/rng-tools` and add the line
`HRNGDEVICE=/dev/urandom`
3. Start the rng daemon
`/etc/init.d/rng-tools start`

[IMPORTANT]
This instructions are valid for Ubuntu. The package name and initialization commands may change on other distributions.
