Spawn system with wave management for enemies

Pattern: Variables CurrentWave(int)=0, EnemiesAlive(int)=0, EnemiesPerWave(Array<int>). StartWave: CurrentWave++ → SET EnemiesAlive=EnemiesPerWave[CurrentWave]. Timer looping: Branch(SpawnedThisWave < EnemiesPerWave[CurrentWave]) → SpawnActor(EnemyClass, RandomSpawnPoint) → SpawnedThisWave++. OnEnemyDeath: EnemiesAlive-- → Branch(EnemiesAlive <= 0) → StartNextWave or Victory.

Sound Wave

A raw audio clip (.wav). Imported into the project, then wrapped in a Sound Cue or Metasound for playback.

Sound Cue

A graph that mixes and routes one or more Sound Waves — fades, randomizes, attenuates. Older but battle-tested.

PlaySoundAtLocation — play a 3D positional sound at a world location

PlaySoundAtLocation — play sound at world location

UGameplayStatics::PlaySoundAtLocation.

AddImpulse — apply instant impulse to physics body

One-shot force. bVelChange=true treats Impulse as velocity change.

Less (float) — A < B

PlaySound2D — play a non-positional 2D sound

2D sound — no world position, good for UI sounds and music. Use PlaySoundAtLocation for world sounds.

AddImpulse — apply an instant velocity change to a physics body

bVelChange=true treats Impulse as direct velocity change (ignores mass). bVelChange=false treats it as a force impulse (mass-dependent).
