[Script] and [Animations] - Dead Birds

[Zorkaz]

I created a custom crow and want it to be dead when the cell loads. But how can I script it when there's no gamebryo animation?

Hmmm... interesting question... I'll see if I can find an answer.

 

edit:

By the looks of it there have to be several Havok animations inside the behavior graph .hkx data (Critters\Crow\CrowProject.hkx) corresponding to the properties available for the BirdCritterScript (NPCCrowCall, NPCCrowCallDistressed, NPCCrowWingFlap, NPCCrowWingFlapLand & NPCCrowWingFlapTakeoff. (also noticed the absence of NPCCrowDead or similar)) even though non is mentioned under Havok Anim.

 

or could they possibly be fully scripted?

I mean there's a clue in the bird script itself (Attached to Crows and Seagulls), but I cannot completely make sense of how it works
