More info: this happens 100% when EntityBoss touches EntityPod (investigated which objects participate in CheckRelThing function). Also, after some tweaking I knew that if EntityPod is not made nonsolid (by calling A_NoBlocking) then game will play longer, like maybe 10-15 seconds, but still crash after with same error.

On level "Entity Lair" as soon as Entity appears and is about to go to chase state (or just after it does), game crashes:

- (None)
- VObject::ExecuteFunction
- (linespec.SpectralMonster.Touch)
- VEntity::CheckRelPosition
- VEntity::TryMove
- VObject::ExecuteFunction
- (decorate.EntityBoss.None)

- VObject::ExecuteFunction
- (linespec.Actor.A_Look)

- ServerFrame
- Host_Frame

ERROR: Segmentation Violation

Vavoom build with code revision 4040: Same thing happens, only Entity able to shoot one lightning, and also error message is more clear:

- VEntity::CheckRelPosition
- VEntity::TryMove
- VObject::ExecuteFunction
- (decorate.EntityBoss.None)
- VEntity::SetState
- VEntity::AdvanceState
- VObject::ExecuteFunction
- (linespec.EntityEx.Tick)
- VThinker::Tick
- VLevel::TickWorld
- SV_Ticker
- ServerFrame
- Host_Frame

ERROR: Assertion failed: Index < ArrNum

EDIT: Very similar crash happens with Oracle monster. I believe there's something wrong with this Spectre/Alien/Entity actor physics or behavior.

Allright, here it goes. I ran Vavoom from MSVS with debugger, and after some time fighting vs Spectre MSVS thrown a memory access exception. It was in pr_exec.cpp in RunFunction(), line 174:

if (func->Flags & FUNC_Net)

most of the object members 'func' pointed to were shown as "cannot evaluate", which may mean that memory was thrashed there. Call Stack:

In common progs SpectralMonster::Touch, you needs to be like this:

//==========================================================================
//
//	Touch
//
//==========================================================================

bool Touch(Entity InOther)
{
	EntityEx(InOther).Damage(self, self, 5, 'Melee');
	
	return ::Touch(InOther);
}

Since actor spawns over the entity nest object and touching it the function needs to return touching physics too <!-- s;) --><img src="{SMILIES_PATH}/icon_wink.gif" alt=";)" title="Wink" /><!-- s;) -->.

Ha ha! Firebrand, you're genius! <!-- s:D --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt=":D" title="Very Happy" /><!-- s:D --> That method simply does not return a value. ..... actually I notified Janis that compiler does not check obligatory "return" statement longlong ago <!-- s:roll: --><img src="{SMILIES_PATH}/icon_rolleyes.gif" alt=":roll:" title="Rolling Eyes" /><!-- s:roll: --> <!-- l --><a class="postlink-local" href="http://vavoom-engine.com/forums/viewtopic.php?f=1&t=759">viewtopic.php?f=1&t=759</a><!-- l --> and now this... <!-- s:wink: --><img src="{SMILIES_PATH}/icon_wink.gif" alt=":wink:" title="Wink" /><!-- s:wink: --> EDIT: Tada!! it works, I can play Strife now <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->
