|
* This function check whether a spall event has occured and generates spall.
|
|
*
|
|
* Arguments:
|
|
* 0: The object a projectile hit <OBJECT>
|
|
* 1: The config name of the projectile <STRING>
|
|
* 2: The projectile that should cause spalling <OBJECT>
|
|
* 3: The position (ASL) the projectile hit the object <ARRAY>
|
|
* 4: The old velocity of the projectile <ARRAY>
|
|
* 5: The projectile's shotParents <ARRAY>
|
|
*
|
|
* Return Value:
|
|
* None
|
|
*
|
|
* Example:
|
|
* [[1000, 45, 60], 0.8, getPosASL ace_player] call ace_frag_fnc_doSpall
|
|
*
|
|
* Public: No
