HitPart EH does not return projectile object for unguided rockets
Reviewed, NormalPublic

Description

As a scripter, I want to know where rocket explodes, so that I can calculate blast power that affects vehicle and its individual parts.

HitPart EH works perfectly for most projectiles with exception of unguided rockets.

In case of unguided rocket the object reference is not being returned. Because of that I am unable to get its terminal position or velocity.

Steps To Reproduce

Load attached mission

or create it from scratch:

  1. Create player unit with RPG-32
  2. Create any vehicle with init field:
this allowDamage false; this addEventHandler ["hitpart",{{diag_log "[#hitpart]"; systemChat str [_x select 2]; diag_log [_x select 2]} forEach _this; systemChat str [{_x select 10} count _this > 0]; diag_log [{_x select 10} count _this > 0]}]

Run mission

  1. Hit vehicle with rifle round
  2. Hit vehicle with unguided rocket
  3. System chat will print out object model name or <NULL-object>, and whether there was at least one direct hit.
  4. Results will be stored logged to RPT behind tag [#hitpart].

Observed:

  • [tracer_red.p3d] or similar is returned for rifle round, but <NULL-object> is returned for unguided rocket
  • There are no direct hits (true) for unguided rocket

Expected:

  • Valid object is returned by hitPart EH also for unguided rockets
  • There should be at least one direct hit with unguided rocket as it hits the target
Additional Information

Providing fake direct impact information without reference to projectile, but containing information about terminal position and velocity is acceptable solution.
Fixing this issue will give modders ability to develop superior damage system for Arma, easier to set up in content.

zGuba renamed this task from HitPart EH runs too late for unguided rockets - no projectile object available to HitPart EH does not return projectile object for unguided rockets.

Hello,

thank you for the feedback.

Could you please tell me what branch are you on? There were changes made to this EH since the 1.62 update that are already included in the development branch and should be also available in the RC branch.

razael,
I tested the issue under 1.64 RC and it is still broken there.
