'Vinter Map' is an interactive web map built using Leaflet.js for the video-game ‘Longvinter’. It's used to display the locations of the game's various locations and items to help players navigate the game world and complete objectives. It is available at vintermap.co and the source code is available on my GitHub.
What problem did I set out to fix?
'Longvinter' is an early-access video-game with a growing community and, as such, the information available online is very limited. The project began after I saw a group of users in the game's Discord server using a static image of the map to find in-game items. As the game doesn't include a map, the community had created a few image guides to locate items and navigate the world. This was a good start, but I wanted to create something more interactive and user-friendly.
How did I build it?
I started by reading up and learning more about Leaflet.js. Whilst this was my first time using the library, there were a few resources online that helped me get started. Longvinter's community were kind enough to provide me with an high-resolution image of the map and a folder of icons for the various items in the game. I used Photoshop to slice the image into tiles of variable zoom levels and used the icons to create a JSON file containing the coordinates of each item. I then used the Leaflet.js API to create a web map and add the tiles and markers to the map.
What was the most challenging part of the project?
The most challenging part of the project was deciding the best way to store the data for each item. I was initially storing each instance of an icon as a seperate array, containing the name, icon and coordinates of that instance. However, this meant I had a lot duplicate information and I had to write a lot of repetitive code to add each item to the map. I solved this by creating an array of objects which each stored one item, it's icon and every set of coordinates for that item. This meant I could loop through the array and add each item to the map with a single line of code.
What did I learn?
Creating Vinter Map taught me a lot about Leaflet.js and, while it may not be something I use often, the learning process was very rewarding. I also learnt about different ways to store data and how each method can be used to solve different problems.
What will I do differently next time?
If I were to start this project again, I would make use of a framework such as React.js to create the UI. I would also make use of a database to store the data for each item, as this would make it easier to add new items and update the map in the future.
