+ Move List Strategy
> For this strategy a predefined list of moves have to be given, the list may contain all allowed moves like mentioned in User Move Strategy
> > To create your own Move List strategy it needs to be located in /racetrack/moves and be named as *track_name*-car-*character_of_car*.txt and be a txt file.
+ Path Follow Move Strategy
> A list of point has to be given to the follow move strategy, the strategy will then calculate the route to cross each point in the given order.
> A list of points given in a txt file where on each lime a coordinate is placed like (X:24, Y:22) gets used to calculate a path which makes the car cross each point.
> > To create your own follow move strategy it needs to be located in /racetrack/moves and be named as *track_name*_points.txt and be a txt file.
+ Path Finder Strategy
> The pathfinder Strategy Calculates a route itself and follows it direction fully automatically.
The shown Track can be interpreted as following:<br>
'spaces' are part of the raceable track.<br>
'#' is a Wall<br>
'>,<,^,v' are finish line components<br>
'X' is shown if a car crashes at its crash location.<br>
And every other character represents a car.
> To create your own track it needs to be located inside /racetrack/tracks and be a txt file.
### Determining a winner
The winner gets determined automatically. <br> The car that first passes the finish line (doing a complete round) is given the win, if all car except one crash the surviving car will be crowned as the winner.<br>The game will inform you of this, and you will have the option to quit the game or play another match.
## Branching Model
We choose a simple branching model where all starting features got a branch and where merged into the main branch, some branches who needed unfinished code to be completed where taken from the game branch but merged into the main at the end as well.<br> Since there was just one end product we abstained from using a development branch and merges where done straight into main.
