Base Physics Object (BP_TFA_BasePhysicsObject)

Base class for physics props like dropped magazines and casings.

Asset path: /Game/InfimaGames/TacticalFPSAnimations/Common/Core/Weapons/BP_TFA_BasePhysicsObject

BP_TFA_BasePhysicsObject is the shared base class for physics props such as dropped magazines and ejected casings. It mainly provides destroy-timer handling and impact-sound behaviour so the child Blueprints can stay lightweight.

Key Variables

---

• ImpactSound (SoundBase)

• Time Until Destroyed (float)

• bPlaySoundOnce (bool)

• MinimumForceToPlaySound (float), default 100.0

---

BeginPlay Behaviour

---

On BeginPlay, this Blueprint calls SetLifeSpan(Time Until Destroyed).

If Time Until Destroyed is 0.0, Unreal clears the lifespan timer. That means the actor can remain indefinitely unless another system destroys it.

---

Impact Sound Logic

---

The hit event is bound to SM_PshyicsObject, which is the technical component name used in the asset.

• If bPlaySoundOnce is true, the Blueprint uses DoOnce to avoid spam and plays ImpactSound at the object’s world location.

• If bPlaySoundOnce is false, it checks the NormalImpulse magnitude against MinimumForceToPlaySound, but that branch currently does not play anything.

In the default setup, only the bPlaySoundOnce = true path plays impact audio. If you want threshold-based playback instead, add that logic in your own child Blueprint.
