// Port of some collision functions to Odin by Jakub Tomšů.

// from Real-Time Collision Detection by Christer Ericson, published by Morgan Kaufmann Publishers, © 2005 Elsevier Inc
//
// This should serve as an reference implementation for common collision queries for games.
// The goal is good numerical robustness, handling edge cases and optimized math equations.
// The code isn't necessarily very optimized.
//
// There are a few cases you don't want to use the procedures below directly, but instead manually inline the math and adapt it to your needs.
// In my experience this method is clearer when writing complex level queries where I need to handle edge cases differently etc.

Minimal D3D11 sprite renderer

Minimal D3D11 sprite renderer: basic back-to-front sprite rendering reference code with example sprite sheet animation logic. As usual: Complete, runnable single-function app. No modern C++ / OOP / obscuring cruft.

Swap out the sprite sheet with a font atlas for a lightweight GUI / text renderer. Clip individual sprites and glyphs by offsetting screenPos and atlasPos to top left corner of visible area and adjusting size accordingly (all values in pixels):

sprite.screenPos.x += 17;
sprite.screenPos.y += 10;

How to handle asymmetry of WAV data?

WAV files can store PCM audio (WAVE_FORMAT_PCM). The WAV file format specification says:

The data format and maximum and minimums values for PCM waveform samples of various sizes are as follows:

Sample Size	Data Format	Maximum Value	Minimum Value
One to eight bits	Unsigned integer	255 (0xFF)	0
Nine or more bits	Signed integer i	Largest positive value of i	Most negative value of i
