Re: The Lounge
I'm a goddamn failure. Also I made way too many errors and had to stop to fix them.

Re: The Lounge
I still remember being forced to play a metric crap ton of stupid typing games in middle school. Those were some dark times...but it payed off seeing as I had to type than I ever had to before , last semester. I'm sure I'll have to type an epic for science or to advance in higher ed sooner or later. Right now Imma chill and not tire at typing, but I can type fast without looking at the keyboard and have little to no errors (depends on how I'm feeling). Alas, we shouldn't be boastful (pointing at me mostly)?

I learned how to touch type thanks to PC gaming.

I didn't learn to touch type thanks to PC gaming.
Left hand home row is Shift A W D Space while right hand is on mouse or hovers above the right side of the keyboard.

Are we all being typing nerds? Ok, guess I'll join in.

On another note, messing around with CC detection. Old circular detections would use either a distance check (on every object, which is slow) or a radial raycast:
Inconsistent density of points, not very pretty. Has to do a rotation for each ray.
More recent ones have used the Fermat's Spiral method, which has consistent density:
Nicely consistent, has the advantage that the first point detected is roughly the closest object, but has to do a rotation operation on each point, slower than the radial raycast.
Most recently I've cobbled together a gridded-circle style detection:
It does a squareroot for only a quarter of the points (one quarter "slice" of the circle) and the rest are just flipping positive/negative of the first quarter points. Consistent density of Fermat's Spiral and should be as fast if not faster than the radial raycast.

Re: The Lounge
Correction: Gridded circular detection does a number of square root operations equal to the number of points that make up the circle's radius. So it's much more efficient than previously stated.

Re: The Lounge
Have some improved detection demos.
Radial Raycast Performs one sin() and one cos(), and then a bunch of addition/subtraction. Fast. Uneven distribution.
Fermat's Spiral Has to perform a sin(), cos(), and sqrt() on top of addition/subtraction for every point. Slow. Even distribution. Can be used for finding closest-object.
Archimedien Spiral Performs one sin() and one cos(), and then a bunch of addition/subtraction. Simpler code than Radial Raycast. Fast. Uneven distribution. Can be used for finding closest-object.
Gridded Circle Performs a sqrt() for the number of points that make up the radius, and then a bunch of addition/subtraction. Moderately fast. Even distribution.
Grid Only performs addition and subtraction. Super fast. Even distribution, but it's a square.
