New article on my Patreon: we examine the creation of spaceships for the recent game Command Deck, which brings to life the covers of 1960s and 1970s sci-fi novels illustrated by fantastic artists like Boris Vallejo or John Berkey. @commanddeck.bsky.social

Enjoying this a lot so far. More games could have spaceships that look like they're from 1970s book covers, I'm just saying.

Our early access release date is just two weeks away for our roguelike deckbuilder. 🚀 Now we just have to pray that @megacrit.com doesn't surprise drop Slay the Spire 2 on the 25th. 🤞 #gamedev

We built a palette system for our UI and have some fun ideas for how we can use it. But now we need to decided what colours to use by default.

Help us decide which colour scheme we should use for our UI! We'd love to hear what you think of these options. #screenshotsaturday #gamedev

I wrote this up for reddit, but maybe people here will find it interesting or helpful. We added a ramming maneuver to our deckbuilder. But it came with a nasty bug that was particularly difficult to track down due to some Unity quirks. A thread. 1/6

Takeaways: - Bad floating point values in a Transform or RigidBody can lead to hard crashes in Unity - Unity prevents these values from being assigned when running in Editor, but not in builds - Always watch out for divide by zero edge cases 5/6

Finally: If you ever see even a single error in your Editor Console that looks like `rigidbody.force assign attempt for 'Object' is not valid. Input force is { Infinity, Infinity, Infinity }.` for the love of god listen to it 6/6

If an Update call happened to land at exactly the same time as our intercept time (a 32-bit float) then we would divide by zero and assign an Inf acceleration to a RigidBody. And then other objects would reference the ship's position and end up with Inf in their transforms. 3/6

This lead to our game hard crashing to the desktop with an 'Overflow in memory allocator' message in the logs. Did you know that Unity prevents assigning Inf and NaN to RigidBodies and Transforms in *Editor* but doesn't catch the bad values in builds? 4/6

We're really happy with how the ramming maneuver is working in Command Deck. But this bug caused us huge headaches because it was very rare and would occur in builds but not in Editor. 2/6
