well there is a get parameter for the trigger
/// [Trigger Control]
/// <para>Indicates 1.0 when the corresponding trigger is pressed.</para>
/// <para>Trigger # is equal to subtype.</para>
/// <para>The trigger # is counted within the machine, not the controlling puppet.</para>
/// </summary>
C_Trigger,
there are also ammo counter parameters which could be queried to see if reducing??
these any use for what you are trying to achieve?
