Wave Spawning System

**Wave Spawning System is a 100% blueprint powered spawning system for quickly and easily setting up enemy waves in Unreal Engine.

Marketplace Page: https://www.unrealengine.com/marketp…pawning-system**

The Wave Spawning System will allow you to quickly set up & spawn hordes of enemies in your game. Simply define the waves in a data table, add a Wave Spawn Controller to your level and link it with spawn points, and begin spawning right away!

Using a batching system to define clusters of AI units within a wave, the Wave Spawning System allows you to set up huge waves comprising of multiple groups of enemies with minimal effort. Each batch of AI units can be customized independently using parameters such as spawn starting time, time intervals between spawns, spawn point, and number of units, to create a diverse set of enemy waves that match your specifications.

The Wave Spawning System also supports multiple spawning modes: use either the basic Fixed Location spawn points or Spawning Volumes that generate randomized spawn locations over larger regions, with fail-safe tests that maximize the probability of finding valid spawn locations.

Update Logs:

The v1.0.1 update has gone live on the Marketplace.

Change Log:

  • AI Stats Control parameters are now passed at spawn as structs instead of individual float variables like Health Multiplier, thus enabling new control parameters (for example, a damage multiplier) to be added without requiring any changes to the default workflow.

  • Added a fail-safe test to ensure that Stats Control parameters are initialized (with default multiplier values of 1.0) for at least a single wave cycle.

Additional Notes:

  • Search for Version****1_0_1 in the blueprint editor to identify all new changes in this update.

Hi, I’ve shared a free Win 32 executable demo based on the sample gameplay map that comes with the Wave Spawning System. So if anyone’s interested in trying it out before purchasing, you can download it from Dropbox and have a look at it yourself: https://www.dropbox.com/s/dttnlznblx…20Demo.7z?dl=0

Gameplay Demo Description:

  • One Wave Cycle comprising of 10 waves
  • Boss Spawn at the end of the final wave
  • Two player weapons: Projectile (basic) & Railgun (penetrating hitscan)
  • Four enemy types: Grunt (basic), Mutator (keeps growing if left alive), Elite (additional zig-zag motion to make targeting difficult), & Boss (with two side turrets that can attack player)

Input Controls:

Two additional tutorials have also been uploaded:

Hi, I’ve added a new tutorial for setting a limit on the maximum number of AI units that can be active in wave at any time: Wave Spawning System Tutorial: How to add Spawn Limiters to limit Max Spawned AI - Google Docs

So if you want to control the max concurrent unit count, you can now do so by making a few small changes to the AI Batch Spawner & Wave Spawn Controller blueprints. The wave spawning system will then spawn new units until it reaches the max unit count, then stops, & continues again once the unit count drops below the threshold.

The v1.0.4 update has gone live on the marketplace. This is a minor update that focuses on usability improvements based on customer feedback.

Change Log:

I. The AIPointsDistribution array has now been moved from the example Game Mode BP to the BP_WaveSpawnController blueprint and set to Instance Editable for easy in-editor customization. This array can be used to specify the number of points given to the player when an AI unit is destroyed. And you can specify the points separately for each AI class as shown below:
