SFAS Day 1

My 2 weeks started yesterday for the second round of the Search for a Star competition. The competition is a nationwide programming challenge for students and graduates that attempts to mimic an application process.

The second round gives contestants 2 weeks to make a game in Unity and publish it to the Windows Phone store. Last year my project got me a ticket to the final round interview, which was a miracle in itself given how restricted I was working on a slow, near broken laptop. I even had to take it to lectures to make progress as it was the only way I’d have time to finish everything. It was also one of my first times really using Unity.

Not my best work, but for a 2 week time-limit I was more than pleased with it!

Upgrade Your Workflow

This year, my placement has afforded me a proper setup, complete with a high-end desktop and multiple monitors, in addition I’ve booked time off work to focus on the project for its duration!

Having a faster machine has also allowed me to spend time looking at workflow improvements before going ahead with implementation. In my first blog entry I was looking at creating Tilemaps out of meshes, and said that I’d like to create an editor to allow for user created tilemaps.

So that’s what I focused on for Day 1, I rewrote the tilemap scripts and scriptable objects infrastructure, then proceeded to write an EditorWindow with very basic functionality for creating a level (or “Wave” as it’s called in this project)


Draft 2D Level Editor

It’s no Tiled but it will certainly do.

So how is it used? First you set the dimensions of your wave, and the window will resize itself to accommodate a grid which fits your given size. Left-click dragging will create black ‘walls’, while right-click dragging will erase them. All that’s left then is to enter a name and click ‘Save Wave’, Unity then creates an asset out of your drawing.

The ‘Wave’ asset, the string property is an artifact from not having the level editor originally, you can change the level with this provided its length agrees with the width and height.

Under the hood, the window itself works by calling DrawRect() and referring to a 2D array of integers to determine which colour to use for each rectangle, the window automatically resizes as you change the dimensions of your level as well.

Since my tilemap script attempts to stitch edges and corners together algorithmically, I have no need for a tileset display or the ability to see what tile you’re placing in this version, though it wouldn’t be too tricky to implement and certainly something I would add before releasing any of it.


On to Day 2

Today’s work will involve getting a factory in place to generate the level, the level is made up of ‘Waves’ which my editor is used to create. A Wave is just a segment of the level, I’ll create a large pool of preset waves which the factory will then choose between when it comes to generate the level.

Level will be assembled from randomly selected presets, Player will ask Level if it’s colliding with any of the tiles in each Wave.

Having an editor allows me to ensure that the waves are surpassable, and also allows me to do things such as pick viable locations for collectibles such that they will never be unreachable.

Hopefully my post tomorrow will give more of an idea of the actual gameplay as I wrap up on this workflow business.
