Time-Driven Simulation

Build

To build the project, it is necessary to have Maven +3.5.0, and Java SE 8 Release installed. Then, run:

$ mvn clean package

This will generate a *.jar in the target folder. If you find any issues with the building, remove the *.jar files from the Maven local repository with:

$ rm -fr ~/.m2/repository/ar/edu/itba/ss/*

Or do it manually, if you prefer.

Execute

In the root folder (after build):

$ java -jar target/tp4-1.0-SNAPSHOT.jar <simulate | animate>

Help

$ java -jar target/tp4-1.0-SNAPSHOT.jar help

Input Files Format

Receives a JSON file with the following format (see example below):

{
	"fps"			: "100",
	"deltat"		: "100.0",
	"integrator"	: "Beeman",
	"system"		: "GravitationalField",
	"output"		: "resources/data/beeman.data",
	"maxtime"		: "157680000.0"
}

Output File Format

Simulation file

<x> <y> <r> <vx> <vy>
...

Animated file

<N>
<t0>
<x> <y> <r> <v>
...

Where <v> is the module of the speed.
