Hi there.
I just started to use this library and have some (hopefully) improvements for this lib.
Changes in
src/node.jswill reuse thebestGuessDistancehaving a minor impact on memory usage and performance benefit in chromium on big grids.Changes in
src/easystar.jsare improving the directional constraint checks.Directional constraints are represented in a bitfield instead of a string array.
A check if the field is accessable by the given direction is the performed by a simple
&operationsrc/easystar.js:475This should greatly improve the performance of directional constraints
Sadly there is no benchmark realy using directional constraints.
I am not shure about
src/easystar.js:478but it might also improve performance https://jsperf.com/for-loop-vs-indexofThe tests run smoothly and the benchmarks show a great improvement on larger grids.
I would be happy to discuss these changes.
Best
Bellian
