npc_advisor

For the lore character, see Advisor.

npc_advisor is a point entity available in Half-Life 2: Episode Two. It's the sluggy, evil, worm like things that are known as Combine Advisors. They are capable of using telekinesis to levitate multiple objects and throw them at the player, inflicting damage. Objects are first "staged" by being flung to one of several pre-determined positions, then flung at the player one at a time, or all at once.

Note:Some keyvalues, spawnflags, effect flags, inputs, or outputs might not affect an NPC, based on the functionality and coding of the NPC.

Bugs

This NPC does not load the advisor model by default - it must be specified by keyvalue! Without a model, a null-pointer exception is thrown. This can be fixed by editing npc_advisor.cpp.

1. On line 376, replace SetModel( STRING( GetModelName() ) ); with SetModel( "models\advisor.mdl" );
2. On line 1554, replace PrecacheModel( STRING( GetModelName() ) ); with PrecacheModel( "models\advisor.mdl" );

Also, advisors will not attack the player, or levitate props unless you set NPC_ADVISOR_HAS_BEHAVIOR in npc_advisor_shared.h.
