# BIN_fnc_probeVeinHitpoint

*Function · Probe · Arma 3 v1.94*

Locality: executed with **spawn**

## Description

Reacts to a hit on a vein of the alien probe: the vein is retracted with [BIN_fnc_probeAnim](../functions/BIN_fnc_probeAnim.md) (retract sound, the looping sound fades out and is deleted), and after a delay it is expanded again (expand sound, a new looping sound is created).
The delay is 4 seconds by default and can be changed by setting the variable "bin_probe_retractTime" on the probe itself.
The function does nothing if the hit part index is -1.

Its parameters match the [Dammaged](../topics/Event_Handlers.md#dammaged) event handler, from which it is meant to be executed; no other Contact function calls it. As it uses [sleep](../commands/sleep.md), it must run in a [scheduled environment](../topics/Scheduler.md#scheduled-environment).

## Syntax

```sqf
[probe, selection, damage, hitIndex, hitPoint] spawn BIN_fnc_probeVeinHitpoint

- `hitIndex`: [Number](../topics/Number.md) - (Optional, default -1) hit part index of the damaged hitpoint; the function exits if it is -1
