I work full time at a big software company, when I'm not doing that I'm developing games. I keep a development blog at www.byte56.com and you can follow me on twitter.

I've created a course with Lynda.com to teach advanced scripting with the Unity 3D engine, check it out!

comment Physx gravity not working as expected
You don't have any other forces being applied to the vehicle? Something to keep it on the road in the first place? Can you post a snippet of code showing how you've created the car and how you're updating it. Smallest amount of code possible.

comment Physx gravity not working as expected
I'm guessing if you were to flip the car upside-down it would float up into the air? It seems as though you're applying the gravity to the cars local down, instead of the world down. Nice improvements on the question.

comment Most practical isometric tile, or does it even matter?
Sure. It's important not to get hung up on the details. Things can always be fixed later if needed. Typically it's more important to just make a decision and move forward.

comment How to decide on game ideas in a team
Based on the type of answers this is generating, mine included, I converted my answer to CW. Since really, it's just a discussion with people making suggestions.

comment Is the Manhattan distance monotonic when used as heuristic function?
I don't know why you say it's incorrect, you appear to be insisting this answer is incomplete. The proof in your answer appears to be just as weak: "the manhatten distance is consistent...", you then go on to reiterate the original specifications of the question, following with how it would be non-admissible if the scenario were different. I didn't feel as though the answer warranted a full mathematical proof. If you feel this question requires that, then please include it in your answer and I will up vote it. Thanks for the constructive criticism.

comment Is the Manhattan distance monotonic when used as heuristic function?
I believe by the definition you linked, the Manhattan distance is consistent. The green line distance would be using a different heuristic. The Red, Blue and Yellow lines show that the distance between the two nodes remains the same (when using the same heuristic). Moving closer reduces the heuristic and moving farther away increases the heuristic. This meets the monotonic requirement of the OP. As the graph is constructed, with a node at each "intersection", the Manhattan distance is consistent. If it were a different scenario (like allowing diagonal movement), the heuristic would be bad.
