Code crunchers is a 2D platformer game developed by Jack Harris, Alex Vorraro, Sean Atherton, Jayjun Oh, Christopher Duncan and Bruno Fosenca for RMIT-CPT111-2022 (Building IT Systems), This project and related course work submissions yeilded a High Distinction result for all group members.
Welcome to Code Crunchers! In Code Crunchers, you play as a first year programming student with no prior coding experience who must progress through 3 stages of programming. But this is no ordinary programming course! You will need to navigate through increasingly tricky levels and defeat enemies using your coding weapons, but beware – the dreaded Master of Bad Coding lies in wait to challenge any would-be programmers! Collect power ups by defeating enemies to help you progress and defeat the Master, or try to complete the game as quickly as possible to earn a high score!
Code Crunchers is a 2D platforming game.
Code Crunchers functions as a side-scrolling action game: the player needs to progress through a series of increasingly difficult levels, each populated with a different layouts and selection of enemies, with the aim of reaching and defeating the final boss at the final game level. The player has the ability to move left and right, jump over obstacles or between platforms, and shoot their weapon to defeat enemies. Enemies may drop ‘power ups’ which will improve the player’s weapon damage or movement and help them progress through the game. The game will record the player’s score, and allow them to save their scores for sharing.
For this project we set out a number of programming technical goals that we wanted to achive, firstly the game should not use a game engine! we will write as much of the core code our selfs and developit using the Java Grapthics 2D library, Secondly we will generate our levels via procedual level generation, this means each level is always random and different orders, these levels will be loaded from a file that contains each room. Lastly we will have a real high score and user login system where the user authenticates with a API to access the game, then uses this authenticated key to post high scores back to the server at the end of each level attemp.
Our login function is simply called on button click in the login, this will check for blank values first, then check for a !this.app.authLogin(), this is the facade caller that links to the http post request provider and returns true or false for valid login deatils.
public void login(){
if(this.emailInput.getInput().isBlank() || this.passwordInput.getInput().isBlank()){
this.app.playAudioClip("ui-fail");
this.app.resetAudioClip("ui-fail");
this.invalidLoginAlert.setText("Please enter your email and password");
this.invalidLoginAlert.setState("login");
}
if(!this.emailInput.getInput().isBlank() && !this.passwordInput.getInput().isBlank()) {
if(!this.app.authLogin(this.emailInput.getInput(), this.passwordInput.getInput())){
this.app.playAudioClip("ui-fail");
this.app.resetAudioClip("ui-fail");
this.invalidLoginAlert.setText("Invalid email or password");
this.invalidLoginAlert.setState("login");
}else{
this.app.playAudioClip("ui-click");
this.app.resetAudioClip("ui-click");
this.app.setCurrentState("menu");
}
}
}
Below is an example of our procedule room file, this stores all the infromation relating to generating the levels, first off we see that we add a number of variables to be loaded into the system, these are used when processing the level segments / rooms. We can see were we are setting the room width and room height as well as the amount of rooms in this file.
//set room variables first
//set room width must match the width of all the lines below,do not put a space after equals
{{room_width}} =21
//set room height must match the height of all the lines below,do not put a space after equals
{{room_height}} =11
//sets the amount of rooms in this file, this must match
{{room_count}} =5
