Coursework of Model-Driven Development

1. Instruction

The Greedy Snake Game Based on Xtext Language

1.1 how to install

There are two methods to build this project

First method: use Git to import

1. In the development Eclipse, use the Git to import the whole projects

2. The 5 projects named org.xtext.example.group16.GreedySnake.XX need to be imported in the development Eclipse.

3. The Java project called Greedysnake need to be imported in the run-time Eclipse

4. In the runtime-Eclipse, right-click the Greedysnake and click Run AS --> JAVA Application -----> choose MainWindow.GreedySnake.game -----> click OK

If using the first method appears something wrong, please choose the second method.

Second method: import manually

1. Download Zip

2. The five projects named org.xtext.example.group16.GreedySnake.XX need to be imported in the development Eclipse.

3. The Java project called Greedysnake need to be imported in the run-time Eclipse

4. In the runtime-Eclipse, right-click the Greedysnake and click Run AS --> JAVA Application -----> choose MainWindow.GreedySnake.game -----> click OK

1.2 how to play

1. Using the key of up/down/left/right to control the snake's direction
2. Using the shift key to release the bullets
3. Aiming to eat food
4. When the snake collides obstacle, it will die, and the game is over.

2. Attention

The error in the org.xtext.example.group16.GreedySnake.ui.test

If you import the project and find errors of ui.test project, please add two new folders-----src and xtend-gen. And the error will be fixed.

About hello.gs

Please do not change the content of hello.gs file in the run-time Eclipse. Because the content is best suitable for this project.

If you really want to change something to test:

1. the tag of snake, food, obstacle could change
2. the speed
3. change the location of images.

3. About Syntax
