Lettersong roguelike devblog 1- a breath of fresh superheated air

^{Here, the player heats up a tile 3 steps east of them while inducing wind pushing away the air at that tile.}

It’s been a little while. Here’s what’s new:

—The world—

-Added a tile-based fluid simulation that replaces the pre-existing simple heat simulation. Now air can flow back and forth, and carry heat (and other properties)

—Magic—

• Glyph added: ‘f’
  • f represents ‘movement’, ‘direction’, and ‘force’.
    “(f 0 1)” adds eastward (“1”) velocity to the air at your location (“0”).

Getting the fluid dynamics working to my satisfaction, physics-and-gameplay-wise (and efficently enough) was a pain, but I’m quite happy with how it’s turned out for now.

I’ve added a debug mode to visualize the direction of airflow. This might be added as a utility spell-effect for the player later on e.g. “(a @ ’(i f))”.
You can see that the example spell I’ve added into the game adds airflow to try and constrain the flow of superheated air to a tight corridor.
Till next time!

^{Burn, baby, burn!}
