# a* farthest point in route

This block is part of the [`a* path finding`](https://docs.rual.nl/block-types/a%2A%20path%20finding) group and was last modified in core [`v10.4.28`](https://docs.rual.nl/core-versions/100428).

- flow `flow`

- start at required `array` Array [x (Number), y (Number)]

- stops required `array` Array [Array [x (Number), y (Number)]]

- Key `value` e.g. areas.tile

- grid width required `number`

- grid height required `number`

- tiles required `array` Array Matrix or Array of States

- allow diagonal `condition` Default: false

- cross corners `condition` Default: false

- flow `flow`

- tile `array`

A typical wiring for [a* farthest point in route](https://docs.rual.nl/block-types/a*%2520path%2520finding/function_calculate_farthest_multi_point_astar): a [function trigger](https://docs.rual.nl/block-types/globals/trigger_custom_function) starts the flow; [with values](https://docs.rual.nl/block-types/array/array_of_values) feeds the `start` pin; [with values](https://docs.rual.nl/block-types/array/array_of_values) feeds the `stops` pin; [number](https://docs.rual.nl/block-types/number/number_default) feeds the `width` pin; [number](https://docs.rual.nl/block-types/number/number_default) feeds the `height` pin; [with values](https://docs.rual.nl/block-types/array/array_of_values) feeds the `tiles` pin; the `flow` out pin feeds [debug](https://docs.rual.nl/block-types/state%2520ui/state_debug).
