// I can't figure any good way that makes the sprite be properly positioned in place, so I am making a bad way.
// first thing, we are going to find the distance that the sprite is from the camera plane.
// this will give us a z distance
// Then we are going to use this z distance in the renderer algorithm we have for the voxel engine
// which should make it easier to find the point we are interested, in a way that moves just like the renderer we have
// this is wasteful, but we are probably not going to have many sprites anyway...

Apparently Microsoft just dropped the website that had HTML Help Workshop for download. But it is the only tool that fully properly generates .chm help files and I need it in one of my workflows in a CI system - right now things started to fail because the download vanished.

License wise, would I be violating anything if instead of downloading from Microsoft I downloaded from my own file host to run it? My file host would be exposed in the internet and I would not block people downloading it outside of my CI system if they wanted.

For reference, Microsoft's website download for HTML Help Workshop used to be here: https://www.microsoft.com/en-us/download/details.aspx?id=21138&ved=2ahUKEwi0_bGLxr_uAhWFB9QKHcUdCxIQFjAUegQIURAB&usg=AOvVaw1_oaw66rS-7sanf8ov-cbb

Other related websites, but the downloads are 404 now:

A quick look at Touch Handling APIs in Game Engines

Since the iPhone happened in 2007, touch input has been at the forefront of human interaction with machines. But Game Engines have existed for a reasonable long life, preceding the mobile boom. Touch as a means of interaction with the game world in engines is provided in many ways. Below, we are going to look at different touch APIs to see how they have been provided to enable gaming on our phones. Tilt, camera, and other sensors are going to be ignored so we can focus on touch.
