Flow

The Goal

Making a 2D-grid game using arrays within a week time, together with a classmate.

Challenges

This was the first time working together with somebody while using the priciples of "Pair Programming".
Not only had I never used 2D-arrays before, but also hadn't made a single real game yet.

The Code

When the game starts, after the player selected a level, a grid will be made with all the different dots in place. These places are hardcoded.
When the player clicks on a dot, we check if the mouse is moved while the left mouse button still pressed down.
If they moved to an adjacent space and it is empty; we fill it with a stroke.
If that space is a dot, we check if the colors are matching.

There is an array that tracks the value of each cell. When a cell has either a stroke or a dot, the value is 1; otherwise the value will be 0.
There is another array that has the size of the amount of colors which contains booleans.
When the dots are connected the value of that color is changed to true.
If all the values are 1 and all dots are connected, the level will be deemed completed.
A countdown will start and the player will be sent back to the level select screen where a green checkmark will appear on the level they just completed.

The code is made using a framework that we got from school, which uses SDL and is mostly written in C++.
You can check the code on GitHub here.

So for the first game I've ever made, this ain't too bad.
It was a lot of fun working together with a classmate and suprisingly really helpful.
We didn't really have any problems at all while making this game.
The total worktime was around 4 hours.

Big thanks to my classmate Hanne Soubry, she was a great partner during this project.

You can play the game yourself by downloading it with the download button below.
There are 25 different levels included, so feel free to play all of them!

Keep in mind, do not touch anything and just run the .exe titled "Flow", deleting anything or moving something might break the game.
