Turning this on will result in drawing less frames, speeding the process up.
higher values will increase performance but lower accuracy. setting this to 0 turns the algorithm into dijkstras. very high values turn it into BFS.
1. Unsorted Array (slow)
2. Unsorted Array with an additional index
An unsorted array with an additional indexed (2) is somewhat faster than (1), but needs more memory and works only with certain map layouts.
