Tip: In Chop ‘N Pop: Graveyard Bash, there are three waves of enemies. You can modify the code to enable more waves. Details are below.

• Enemy Wave Manager reference object hosts EnemyWaveManager.ts
  • Script dependencies:
    • Behavior.ts
    • Events.ts
    • NPCAgent.ts
    • PlayerManager.ts
• Three instances of EnemyWaveConfig reference objects hosting EnemyWaveConfig.ts.
  • Script dependencies:
    • Behaviour.ts
• ZombieSpawnPoints and child reference objects:
  • This parent reference object is specified in the Properties panel of each EnemyWaveConfig entity.
  • Each enemy wave is spawned within the vicinity of one of the underlying ZombieSpawnPoint entities, which are just empty reference objects whose positional data is used for spawning.

export const WaveManagerNetworkEvents = {
  StartWaveGroup: new NetworkEvent<{waveGroupName : string}>('StartWaveGroup'),
  StopWaveGroup: new NetworkEvent<{waveGroupName : string}>('StopWaveGroup'),
  NextWave: new NetworkEvent<{waveGroupName : string}>('NextWave'),
  StartingWave: new NetworkEvent<{waveGroupName: string, waveNumber : number}>('StartingWave'),
  WaveComplete: new NetworkEvent<{waveGroupName: string, waveNumber : number}>('WaveComplete'),
  FightStarted: new NetworkEvent<{waveGroupName: string}>('FightStarted'),
  FightEnded: new NetworkEvent<{waveGroupName: string}>('FightEnded'),
};

Tip: Each event sends the WaveGroupName, which corresponds to a property on the EnemyWaveManager script. If you create multiple EnemyWaveManagers, the event system should support it.

1. Deploy listed scripts and their script dependencies into your world.
2. Attach EnemyWaveManager.ts to empty reference object.
3. Create an EnemyWaveConfig reference object for each enemy wave in your game. Attach EnemyWaveConfig.ts to each reference object.
4. Create ZombieSpawnPoints reference object. Beneath it, create separate empty reference objects as spawn points for enemies. You can choose the number to include.

1. If you want to add additional waves of skeletons, zombies or both, right-click the EnemyWave3Config entity in the Hierarchy panel and select Duplicate.
2. Select and rename the duplicated asset.
3. Specify the properties of the enemy wave in the Script properties.
4. Modify the EnemyWaveManager script:
   1. Add in new properties for wave4TimeDelay and wave4Config.
   2. Locate the following:

      if (this.props.wave3Config != null) {
        this.waveConfigs.push({config: this.props.wave3Config, timeDelay: -1});
      }
      
   3. Copy it and paste a version of it just below. Change “3” to “4” in the copied version.
   4. Modify the wave3 version above it to reference the wave4TimeDelay property.

• Duplicate the EnemyWaveManager reference object. Rename it to EnemyWaveManager2 or similar.
• Modify EnemyWaveManager2:
  • Define your enemy waves.
  • Make sure that you provide a unique name to the waveGroupName property.
• Modify GameTriggers.ts:
  • Add a new property to hold the EnemyWaveManager2 entity.
  • Modify the onPlayerEnterTrigger code to trigger via event the EnemyWaveManager2 entity.
• If you are triggering waves off of different criteria then time delays and enemy wave completion, you may need to perform more significant code modifications to EnemyWaveManager2 script.
