*** SpaceShipSim ***
|
|
||||||
====================
|
|
||||||
This is a small simulation program of a space ship (with infinite fuel) in a
|
|
||||||
frictionless environment (space). The idea is to use it for educational
|
|
||||||
purposes.
|
|
||||||
|
|
||||||
# Compiling
|
|
||||||
-----------
|
|
||||||
In order to build this program you will require the following dependencies:
|
|
||||||
|
|
||||||
- GNU GCC (https://gcc.gnu.org/)
|
|
||||||
- CMake (https://cmake.org/)
|
|
||||||
- Allegro 5 (http://liballeg.org/)
|
|
||||||
|
|
||||||
You can then compile the program via the following commands:
|
|
||||||
|
|
||||||
cd build/
|
|
||||||
cmake ..
|
|
||||||
make
|
|
||||||
|
|
||||||
This will create a release build with compiler optimizations. If you would like
|
|
||||||
a debug build then pass the `-DCMAKE_BUILD_TYPE=debug' flag to the `cmake'
|
|
||||||
command. If you would like to install then run `cmake' with the additional flag
|
|
||||||
`-DCMAKE_INSTALL_PREFIX=<install_dir>'. If you are installing as a user then
|
|
||||||
you may want to set the installation prefix to `/usr/local/', and if you're
|
|
||||||
packaging then please consult your distribution's policies. With this you
|
|
||||||
should be able to run the `make install' target and install the binary.
|

============
|
||||||
|
|
||||||
|
Space Ship Simulator is a basic 2D simulator of a spaceship in a frictionless environment. This program was made for educational purposes, and is meant to be quite simple.
|
||||||
|
|
||||||
|
To compile the source-code, go into the project src/ folder and run the following command:<br>
|
||||||
|
<code>$ javac spaceshipsim/SpaceShipSim.java</code>
