Revenants homing puffs

Could someone please direct me to where in the doom source the states/frames for the revenants homing puffs are ?

see `A_Tracer()` function, the first code lines (i looked at Chocolate Doom, but the original source should be the same):

    if (gametic & 3)
	return;
    
    // spawn a puff of smoke behind the rocket		
    P_SpawnPuff (actor->x, actor->y, actor->z);

Thanks Ketmar,

But that is not what I was after. I think I have found the answer anyway ...

https://github.com/id-Software/DOOM/blob/77735c3ff0772609e9c8d29e3ce2ab42ff54d20b/linuxdoom-1.10/info.c#L452

Lines 447 to 451.

ah, sorry. programmer's deformation, i guess: always answer with the code. ;-)
