M PlayerAnimState

The m_PlayerAnimState object maintains a player's animation state. It is shared code. There are two versions, CBasePlayerAnimState and CMultiPlayerAnimState, and two entry points:

Update( float eyeYaw, float eyePitch )

Manages ambient, looping animations (running/swimming, aiming, breathing) based on player velocity and look direction every frame. Typically called from:

• CBasePlayer::PostThink()
• C_BasePlayer::UpdateClientSideAnimation()

DoAnimationEvent( PlayerAnimEvent_t event, int nData = 0 )

Begins a discrete, event-based animation (crouching, shooting, reloading) whenever called. PlayerAnimEvent_t is an enum value that defines what type of animation event this is; it is translated into an activity elsewhere depending on the status of the player (weapon held, swimming, etc).

Implementation

Note:Your player must be using a model set up for player animation for any of this to work. Single-player models are not suitable! Valve don't mind modders lifting their HL2DM models, which are set up correctly.

You must define m_PlayerAnimState in both your client and server classes:

class CMyPlayerClass : public CBasePlayer
{
	// ...
	CMultiPlayerAnimState* m_PlayerAnimState;
	// ...
};

Dispatching

In multiplayer you must dispatch animation events to all onlooking clients, a job which is not performed by CBasePlayer. See m_PlayerAnimState/TempEnt for the temporary entity used by Valve.
