8 | INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES

13 |
14 | Statement of Purpose
15 |
16 | The laws of most jurisdictions throughout the world automatically confer
17 | exclusive Copyright and Related Rights (defined below) upon the creator
18 | and subsequent owner(s) (each and all, an "owner") of an original work of
19 | authorship and/or a database (each, a "Work").
20 |
21 | Certain owners wish to permanently relinquish those rights to a Work for
22 | the purpose of contributing to a commons of creative, cultural and
23 | scientific works ("Commons") that the public can reliably and without fear
24 | of later claims of infringement build upon, modify, incorporate in other
25 | works, reuse and redistribute as freely as possible in any form whatsoever
26 | and for any purposes, including without limitation commercial purposes.
27 | These owners may contribute to the Commons to promote the ideal of a free
28 | culture and the further production of creative, cultural and scientific
29 | works, or to gain reputation or greater distribution for their Work in
30 | part through the use and efforts of others.
31 |
32 | For these and/or other purposes and motivations, and without any
33 | expectation of additional consideration or compensation, the person
34 | associating CC0 with a Work (the "Affirmer"), to the extent that he or she
35 | is an owner of Copyright and Related Rights in the Work, voluntarily
36 | elects to apply CC0 to the Work and publicly distribute the Work under its
37 | terms, with knowledge of his or her Copyright and Related Rights in the
38 | Work and the meaning and intended legal effect of CC0 on those rights.
39 |
40 | 1. Copyright and Related Rights. A Work made available under CC0 may be
41 | protected by copyright and related or neighboring rights ("Copyright and
42 | Related Rights"). Copyright and Related Rights include, but are not
43 | limited to, the following:
44 |
45 | i. the right to reproduce, adapt, distribute, perform, display,
46 | communicate, and translate a Work;
47 | ii. moral rights retained by the original author(s) and/or performer(s);
48 | iii. publicity and privacy rights pertaining to a person's image or
49 | likeness depicted in a Work;
50 | iv. rights protecting against unfair competition in regards to a Work,
51 | subject to the limitations in paragraph 4(a), below;
52 | v. rights protecting the extraction, dissemination, use and reuse of data
53 | in a Work;
54 | vi. database rights (such as those arising under Directive 96/9/EC of the
55 | European Parliament and of the Council of 11 March 1996 on the legal
56 | protection of databases, and under any national implementation
57 | thereof, including any amended or successor version of such
58 | directive); and
59 | vii. other similar, equivalent or corresponding rights throughout the
60 | world based on applicable law or treaty, and any national
61 | implementations thereof.
62 |
63 | 2. Waiver. To the greatest extent permitted by, but not in contravention
64 | of, applicable law, Affirmer hereby overtly, fully, permanently,
65 | irrevocably and unconditionally waives, abandons, and surrenders all of
66 | Affirmer's Copyright and Related Rights and associated claims and causes
67 | of action, whether now known or unknown (including existing as well as
68 | future claims and causes of action), in the Work (i) in all territories
69 | worldwide, (ii) for the maximum duration provided by applicable law or
70 | treaty (including future time extensions), (iii) in any current or future
71 | medium and for any number of copies, and (iv) for any purpose whatsoever,
72 | including without limitation commercial, advertising or promotional
73 | purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
74 | member of the public at large and to the detriment of Affirmer's heirs and
75 | successors, fully intending that such Waiver shall not be subject to
76 | revocation, rescission, cancellation, termination, or any other legal or
77 | equitable action to disrupt the quiet enjoyment of the Work by the public
78 | as contemplated by Affirmer's express Statement of Purpose.
79 |
80 | 3. Public License Fallback. Should any part of the Waiver for any reason
81 | be judged legally invalid or ineffective under applicable law, then the
82 | Waiver shall be preserved to the maximum extent permitted taking into
83 | account Affirmer's express Statement of Purpose. In addition, to the
84 | extent the Waiver is so judged Affirmer hereby grants to each affected
85 | person a royalty-free, non transferable, non sublicensable, non exclusive,
86 | irrevocable and unconditional license to exercise Affirmer's Copyright and
87 | Related Rights in the Work (i) in all territories worldwide, (ii) for the
88 | maximum duration provided by applicable law or treaty (including future
89 | time extensions), (iii) in any current or future medium and for any number
90 | of copies, and (iv) for any purpose whatsoever, including without
91 | limitation commercial, advertising or promotional purposes (the
92 | "License"). The License shall be deemed effective as of the date CC0 was
93 | applied by Affirmer to the Work. Should any part of the License for any
94 | reason be judged legally invalid or ineffective under applicable law, such
95 | partial invalidity or ineffectiveness shall not invalidate the remainder
96 | of the License, and in such case Affirmer hereby affirms that he or she
97 | will not (i) exercise any of his or her remaining Copyright and Related
98 | Rights in the Work or (ii) assert any associated claims and causes of
99 | action with respect to the Work, in either case contrary to Affirmer's
100 | express Statement of Purpose.
101 |
102 | 4. Limitations and Disclaimers.
103 |
104 | a. No trademark or patent rights held by Affirmer are waived, abandoned,
105 | surrendered, licensed or otherwise affected by this document.
106 | b. Affirmer offers the Work as-is and makes no representations or
107 | warranties of any kind concerning the Work, express, implied,
108 | statutory or otherwise, including without limitation warranties of
109 | title, merchantability, fitness for a particular purpose, non
110 | infringement, or the absence of latent or other defects, accuracy, or
111 | the present or absence of errors, whether or not discoverable, all to
112 | the greatest extent permissible under applicable law.
113 | c. Affirmer disclaims responsibility for clearing rights of other persons
114 | that may apply to the Work or any use thereof, including without
115 | limitation any person's Copyright and Related Rights in the Work.
116 | Further, Affirmer disclaims responsibility for obtaining any necessary
117 | consents, permissions or other rights required for any use of the
118 | Work.
119 | d. Affirmer understands and acknowledges that Creative Commons is not a
120 | party to this document and has no duty or obligation with respect to
121 | this CC0 or use of the Work.

59 | ## Features
60 |
61 | - Control a spaceship using keyboard inputs (A, W, S, D, or arrow keys) to move and SPACE to shoot.
62 | - Enemies and boss enemies spawn at intervals, increasing the game's difficulty.
63 | - Collect power-ups to boost your abilities.
64 | - Score tracking and display, with the game increasing in difficulty as your score rises.
65 | - Lives system where players lose a life if an enemy reaches the bottom of the screen or collides with the player's spaceship.
66 | - Reset mechanism to start over once all lives are lost.
67 | - Sound effects for shooting, enemy hits, and power-up collection.
68 | - JavaDoc documentation for the game's classes and methods.
69 |
70 | ## Prerequisites
71 |
72 | - JDK 11 or higher.
73 | - JavaFX SDK (version compatible with your JDK).
74 | - Maven (for building and running the project).
75 |
76 | ## Setup and Installation
77 |
78 | 1. **JavaFX SDK**: Download the JavaFX SDK from [OpenJFX](https://openjfx.io/) and extract it to a known directory.
79 | 2. **Maven Configuration**: Ensure Maven is installed on your system and correctly configured. Alternatively, you can use an IDE like IntelliJ IDEA or Eclipse that supports Maven projects.
80 | 3. **Clone the Repository**:
81 | ```bash
82 | git clone https://github.com/hoangsonww/Space-Invader-Game-JavaFX.git
83 | cd Space-Invader-Game
84 | ```
85 |
86 | 4. **Update `pom.xml`**: Modify the `javafx-sdk.path` property in the `pom.xml` file to point to the JavaFX SDK's location on your system. This is necessary for Maven to build the project correctly.
87 | 5. **Build the Project**:
88 | ```bash
89 | mvn clean install
90 | ```
91 |
92 | 6. **Run the Application**:
93 | ```bash
94 | mvn javafx:run
95 | ```
96 |
97 | If you're using an IDE like IntelliJ IDEA, you can run the `SpaceShooter.java` file directly to start the game.
98 |
99 | ## Necessary Configuration
100 |
101 | Ensure JavaFX is correctly set up in your development environment:
102 | - **IntelliJ IDEA**:
103 | 1. Go to `File` > `Project Structure` > `Libraries`, add the JavaFX SDK as a library by navigating to its `lib` folder.
104 | 2. Modify your run configuration to include VM options for the JavaFX modules you use, e.g., `--module-path "path/to/javafx-sdk/lib" --add-modules javafx.controls,javafx.fxml,javafx.media`.
105 |
106 | - **Eclipse**:
107 | 1. Add the JavaFX SDK as an external JAR to your project's build path.
108 | 2. Adjust the run configurations to include the necessary VM arguments, as shown above for IntelliJ.
109 |
110 | ## How to Play
111 |
112 | - Use the A, W, S, D keys or arrow keys to move the spaceship.
113 | - Press SPACE to shoot at enemies.
114 | - Avoid letting enemies reach the bottom of the screen or colliding with them.
115 | - Collect power-ups to enhance your capabilities and increase your score.
116 | - The game ends when all lives are lost, but you can start over by resetting the game.
