My project ideas board is public. I’ve been helping people make games since 1990. I wrote games earlier in life, with Solar Realms Elite being the most well known, then worked on an …

Graph search algorithms let us find the shortest path on a map represented as a graph. Move the blob (start point) and cross (end point) to see the shortest path found by the A* Algorithm: A* is one of a family of related graph search algorithms: Breadth First Search explores equally in …

3D cartesian coordinates have existing algorithms like distances, rotation, reflection, line drawing, conversion to/from screen coordinates, etc. We can adapt these algorithms to work on hexagonal grids.

Mar 17, 2025 · I create interactive explanations of math and computer science topics at Red Blob Games [1]. I explore topics related to computer game development, as I’ve found that’s a rich source of motivating examples.

I make interactive visual explanations of math and algorithms, using motivating examples from computer games. I work both with educators and game developers. Prevent this user from interacting with your repositories and sending you notifications. Learn more about blocking users.

May 8, 2013 · For example, the neighbor algorithm is written in hex cube coordinates. To use a different coordinate system, like odd-R offset, you’d use convert_cube_to_odd_r( neighbor( …

Apr 17, 2018 · Over the past few weeks I've been reimplementing my guide to hexagonal grids. I'm generally not a fan of rewrites that have no end-user benefits but there are lots of improvements I want to make to the page, and the convoluted code was making it harder to make the changes I wanted.

Aug 17, 2020 · I adding some pathfinding to a game I'm working on. It primarily used A* with as suggested in the pathfinding articles at reb blob games. It works, but isn't very fast. It is a square grid map that...

Jan 18, 2006 · Hello, fist thing is first, im a new member just so u no, enyway, a few years ago on a beach near Bosnia *were i was born* called budva there was a large dark redish blob of goo ( i have no idea what !! ) that had no eyes, legs or other visible featrues, the way it …

Jul 27, 2013 · The Main Messages window (Interface and Tabbed Chat) window can be "hidden" by using the reb blob and it will not actually Quit the apps (As the red blob does in single window apps). The same is true if you have the Buddy Lists (AIM, Jabber and Yahoo Accounts and possibly the Bonjour one) on display.
