Caveats & Gotchas

• bIsUISound=true (default) means this plays even when the game is paused — correct for menus and UI feedback, but wrong for gameplay sounds. Set to false for gameplay-triggered 2D sounds.
• No 3D attenuation — the sound is the same volume regardless of where the listener is. Use PlaySoundAtLocation for world-space sounds.
• Fire-and-forget like PlaySoundAtLocation — no handle returned. Use SpawnSound2D for stoppable 2D sounds.

Example

UI click and achievement sounds C++

// UI button click — plays while paused
UGameplayStatics::PlaySound2D(this, ButtonClickSound);

// Achievement sting — gameplay context, shouldn't play while paused
UGameplayStatics::PlaySound2D(
	this, AchievementSound,
	1.0f, 1.0f, 0.0f,
	nullptr, nullptr,
	false // bIsUISound=false
);
