Enemy Wave Spawner

Before you paste3

• BP_EnemySpawn Actor class

  Set the Spawn Actor Class pin to your own enemy Blueprint after pasting.

• EnemiesPerWaveInteger, default 3

  My Blueprint, then + Variable. Set its default to 3, the size of the first wave.

• SpawnPointsArray of actors, Instance Editable

  Tick Instance Editable and add the three Target Points from your level.

Good to know. The first wave arrives 10 seconds after play begins, and nothing removes earlier waves.

How it works

1. Step 1: 1Start a 10 second timerEvent BeginPlay sets a looping 10 second timer that calls SpawnWave.
2. Step 2: 2One enemy per passSpawnWave runs For Loop from 1 to EnemiesPerWave.
3. Step 3: 3Rotate the spawn pointsIndex modulo 3 picks one of the three SpawnPoints in turn, and Spawn Actor creates BP_Enemy at its location.
4. Step 4: 4Bigger next timeWhen the loop completes, EnemiesPerWave goes up by 2.
