 It is possible to create dynamic sounds and music for you mod using parameters in FMOD.
 This page assumes you already have FMOD set up for your Heroes of Hammerwatch mod. See [[Adding custom sounds and music]] for more information.
 ==Adding a parameter to your sound event in FMOD==
 Open your event in FMOD and use the "+" tab above the tracks to add a new parameter.

-In the new tab for your parameter, add you desired control points to determine how the setting is changed based on the parameter. There is a scale above the tracks showing the range of your parameter, and above that is a knob for your parameter to test how different values sound. you can also set a default value by right clicking on your parameter knob.

-You will need to use you own sValue parameter rather than the standard ones. For example: If you want to have a dynamic shoot sound, do not use the "shoot-snd" parameter because this used by the base projectile classes and would be difficult to alter how it is controlled.

		+	It is also possible to control an FMOD parameter while the sound is playing. Instead of using PlaySound3D, you can call PlayTracked directly on your SoundEvent which will return a SoundInstance. With a reference to the SoundInstance you can execute more control over how the sound plays out. See the [https://docs.heroesofhammerwatch.com/engine/class_sound_instance.html SoundInstance] documentation for all the options. Then you can alter the sound instance as you please in an update method:
		+
		+	class DynamicSoundBeam : BeamProjectile
		+	{
		+	SoundEvent@ customShootSound;
		+	SoundInstance@ = myCustomSoundInstance;
		+
		+	DynamicSoundBeam(UnitPtr unit, SValue& params)
		+	{
		+	super(unit, params);
		+
		+	@customShootSound = Resources::GetSoundEvent(GetParamString(unit, params, "custom-shoot-snd", false));
		+	}
		+
		+	void Initialize(Actor@ owner, vec2 dir, float intensity, bool husk, Actor@ target, uint weapon) override
		+	{
		+	BeamProjectile::Initialize(owner, dir, intensity, husk, target, weapon);
		+
		+	@myCustomSoundInstance = customShootSound.PlayTracked(m_unit.GetPosition());
		+	}
		+
		+	void Update(int dt) override
		+	{
		+	BeamProjectile::Update(dt);
		+
		+	float param = 0.7 // <--- you got this, champ.
		+
		+	myCustomSoundInstance.SetPosition(m_unit.GetPosition());
		+	myCustomSoundInstance.SetParameter("myParameter", param);
