### A* heuristic for a map that can have roads

I have a 2D grid which I am performing A* pathfinding on. Nodes are connected via a value of 3 in most cases (some connections are more expensive). In some (depends on the gameplay) circumstances the ...

### Is speed runs ranking mechanism heuristic or statistics based?

I'm looking to implement some sort of speed run mode in my game. Let's say I want to assign each level three 'winning' bars, (bronze, silver and gold for example), which are independent of the player,...

### Can A* path finding cost functions allow for path following shapes?

Recently I begun developing a game prototype which could create procedural generated dungeons using a collection of room types. To ensure the hallway paths between these rooms would always be ...

### How to choose and scale heuristics for A-star on a graph?

I am trying to find the best and scale my cost function for my algorithm. I am following amit blog which explain that (http://theory.stanford.edu/~amitp/GameProgramming/Heuristics.html#manhattan-...

### AI for Shogi, dealing with high branching factor due to drop rule [closed]

I'm writing a Shogi program with a computer player in Java from scratch as my undergradute dissertation project. Due to the drop rule, when the computer player captures a few pieces, the branching ...

### Pathfinding with portals? [closed]

I'm not making a game with portals in it (one way or bidirectional). These portals instantly teleport characters from one location to another. How would I implement pathfinding? Here's an animation ...

### In A star, how does the heuristic help determine your path?

Say you're using a 4 by 5 grid. The G cost for horizontal and vertical movement is 10, and the G cost for diagonal movement is 14. On this page: http://theory.stanford.edu/~amitp/GameProgramming/...
