Zero divisor when advance throwing Chemlight (IR)

Description:

• When advance throwing a Chemlight IR there is a zero divisor in fnc_exitThrowMode.sqf
  [QEGVAR(common,setShotParents), [_activeThrowable, _unit, (getShotParents _activeThrowable) select 1]] call CBA_fnc_serverEvent;

variable _activeThrowable is in weird form: 8d881600# 178009.
While others are on the form 1779997.
So getShotParents returns a blank array.

The variable is being distorted in fnc_prime here:

// Throw Fired XEH
[QGVAR(throwFiredXEH), [
    _unit, // unit
    "Throw", // weapon
    _muzzle, // muzzle
    _muzzle, // mode
    _throwableType, // ammo
    _throwableMag, // magazine
    _activeThrowable // projectile
]] call CBA_fnc_globalEvent;

Steps to reproduce:

• Open editor
• Spawn soldier with Chemlight IR
• Start advance throwing them

Where did the issue occur?

• Editor (Singleplayer)

Placed Modules:

• None

RPT log file:

• Add a link (gist or pastebin) to the client and/or server RPT file. An instruction to find your RPT files can be found here.
• If possible at the time the bug is encountered, go to ACE Options and select "Debug To Clipboard", this will print extensive debug information to the RPT file.

This was introduced in #5052 it seems.

So CBA_fnc_addeventhandler is taking code as its second parameter.

Should it then be: _this call FUNC(throwFiredXEH) or just call FUNC(throwFiredXEH)?

Because now its just FUNC(throwFiredXEH)

Also is CBA_fnc_serverEvent still a thing? or should it be CBA_fnc_globalEvent.

#5209 possible fix, missing call

[Phyma]

Hope you fix it with that. I still think its a mystery that QGVAR(activeThrowable) get changed in the global event:

prime.sqf
systemChat format ["Before globalevent getvar: %1",_unit getVariable [QGVAR(activeThrowable), objNull]];
// Throw Fired XEH
[QGVAR(throwFiredXEH), [
    _unit, // unit
    "Throw", // weapon
    _muzzle, // muzzle
    _muzzle, // mode
    _throwableType, // ammo
    _throwableMag, // magazine
    _activeThrowable // projectile
]] call CBA_fnc_globalEvent;
systemChat format ["After globalevent getvar: %1",_unit getVariable [QGVAR(activeThrowable), objNull]];

ExitThrowMode.sqf
systemChat format ["ExitThrowMode _activeThrowable: %1", _activeThrowable];

Take a look at https://github.com/acemod/ACE3/blob/master/addons/chemlights/functions/fnc_throwIR.sqf

It deletes the old grenade, creates a new one
then changes the variable back in advanced throwing.

Aa thanks.

That explains alot :)
