navmesh

I'm working on an RTS game, and I'm using navmeshes for unit pathfinding. I do know how to find a general path within a navmesh, but how do you determine if the unit have enough space to turn?

I have units of different shapes (mostly rectangles with different dimensions), and with different turn radii. Additionally some of units can turn in place, and some can move in reverse.

So, how to find a path which unit can follow, considering that it can not rotate easily?

Many things are new in Solaris 11, Autoinstall is one of them. If, like me, you've known Jumpstart for the last 2 centuries or so, you'll have to start from scratch. Well, almost, as the concepts are similar, and it's not all that difficult. Just new. I wanted to have an AI server… >>> More

Do I need path finding to make AI avoid obstacles?

How do you know when a path-finding algorithm is really needed? There are contexts, where you just want to improve AI navigation to avoid an object, like a space -ship that won't crash on a planet or a car that already knows where to steer, but needs small corrections to avoid a road bump.

Why is Reinforcement Learning so rarely used in pathfinding?

The venerable shortest-path graph theoretic algorithm A* and subsequent improvements (e.g., Hierarchical Annotated A*) is clearly the technique of choice for pathfinding in game development. Instead, it just seems to me that RL is a more natural paradigm to move a character around a game space. And… >>> More
