Haven’t posted in a while, been busy with all the things. Switched to Unity and made a handful of proofs of concept. Now making the push to get something playable built. Check out the rough progress: https://www.youtube.com/playlist?list=PLlXbceeLfevwo8YhBIg6JygA0u0EO6ADy

Selections, yo

The solution is hairy. Each of those cubes is a distinct object, instantiated on the fly.

That’s bad. Because I have to track whether I already created one for that position, and remove any that I’ve already drawn that no longer need drawn if they’re not in the current range. Then when I let the mouse go, destroy all of them and clear the tracker set.

hat’s wayyyyyy too much for a single frame.

So it runs in a coroutine. Coroutines are interesting: if a chunk of code takes > 16.666667ms (60 fps), it carries over the execution to the next frame if you put it in a coroutine; it blocks the next frame otherwise, which causes stuttering. In this case, it just runs with a `while(true)` until the mouse is released.

Progress Update May 2018

Progress Update May 2018

Portfolio / Works in Progress

These are my works in progress. I would consider Centipede feature complete, but there are open issues (both enhancements and bugs) that I plan to continue to work on. Resource Quest in Unity is nearly feature complete, and needs polish. The rest are in various stages of abandonment/neglect.

For each project, I keep a journal, and intend to publish a post-mortem on…

Game Dev Session - It's Full of Flies!

Game Dev Session – It’s Full of Flies!

Impatience waiting for a creature to come eat my ship led to a new crazy game mode!

If you can survive 8 or so waves it gets easier, since the sheer amount of mushrooms makes the processing time longer than the interval timer, so everything slows way down.

It’s a feature!

Game Dev Session - Karma Complete

Week-long test coverage montage

Right into the danger zone

Risin’ up to the challenge of our rival

Oh darlin’ my heart’s on fire

Lose your blues, everybody cut footloose

Key takeaways

beforeEach does not reset any spy that it sets. Will need to find another approach if this is needed. I think setting testObjfrom a copy of the target object, then spying on that is enough to avoid problems, but…

Game Dev Session - Stabilizing Tests for Karma Coverage

Game Dev Session – Stabilizing Tests for Karma Coverage

Loading the canvas libs

Now that Karma is all wired up, I can start poking at the tests.

The first problem I need to fix involves canvas-libs. knobsAndLevers uses the supporting object in canvas-libs to set a randomized initial spawn interval for the creatures. The usage is:

this.spider.initialInterval = supporting.getRandom(this.spider.interval.min, this.spider.interval.max);

But knobsAndLever…

Game Dev Session – Test Coverage with Karma

Adding the Karma Test Coverage Tool

I got tired of flailing around in the dark, so after turning on the lights, I started looking into test coverage tools.

A few sources recommended Karma, so I went for it. It’s good (sorry).

Game Dev Session - Canvas Tech Debt

Game Dev Session – Canvas Tech Debt

Addressing some of the technical debt. Not very exciting. So bullet lists.

DID:

Set up Jasmine tests in Robotron (8 specs, 0 failures)

Set up Jasmine tests in canvas-libs (4 specs, 0 failures)

Moved supporting.js stuff to canvas-libs for both Centipede and Robotron

Moved the Sound object from sound.js to canvas-libs for both Centipede and Robotron

Game Dev Session – Twinstick Firing in Robotron

Game Dev Session – Twinstick Firing in Robotron

Planning

More gamepad updates today. This time, specifically for Robotron. I plan to integrate the controls pausing and twinstick shooting.

Pause updates

Updated pause to handle both spacebar and the + key. I should probably find an XBox controller and see if the indices of those buttons are the same as the X-input (they should be; the indices don’t change between D- and X-input, only the dPadloc…

Game Dev Session - Gamepad Controls Library Updates

Game Dev Session – Gamepad Controls Library Updates

Updating the gamepad library

Today, I’m focusing on the controls library. Goal: add right stick capturing without breaking Centipede or Robotron.

Robotron needs the right stick to handle firing. I could just leave controls.js alone and update it’s functionality in the game itself, like this:

var theControls = controls;

Then add stuff to controls like this:

theControls.aNewThing = newStuff;

Or…

Game Dev Session – Nerding Out on Robotron

Pre-Feature Cleanup of Joust and Robotron

Over the weekend, I made a serious dent in the technical debt for the other canvas games, Joust and Robotron.

I spent the better part of Saturday converting the mess of functions of both games into objects. The core logic was left alone, but I did find a few functions to clean up. The diffs were pretty massive due to these restructurings, with nearly full…
