3. Simple Gameplay (Principal)

In order to make gameplay (out of the box) you should:

  • Drag and drop to your own scene blueprint BP_USResponseArea, stored here: \Blueprints\System
  • Drag and drop BP_USTurret3 (turret3 has fast aim time) turret from \Blueprints\Turret
  • Turret must be placed inside BP_USResponseArea wire sphere
  • Drag and drop BP_USFlowSpawner, stored here: \Blueprints\System
  • Make sure spawner arrow directs to response area wire sphere
  • Something like this:


  • Principal action ready. It's time to make some adjustments. See below.

4. Response Area

BP_USResponseArea blueprint (\Blueprints) is a primary service actor for turrets and for enemy ships. Details:

  • Any turret must be placed inside ResponseArea actor for correct working;
  • Any enemy ship fly through ResponseArea becomes a target of a turret (random order for multi targets);
  • Response areas may be overlapped. Response order by internal UE4 engine calculations.
  • Adjustment of response area 'trigger' radius:

5. Turrets

There are 5 turrets types (models):


  • Down Turret - tick for bottom turret placement;
  • Yaw and Pitch aim speed - movement speed for turrets heads (look at current target);
  • Fire Rate - fire speed in seconds (lower values = faster);
  • Ready Time - timeout before first shoot (turret preapare time);
  • Gun Anim Rate - animation speed for gun (just visual).

6. Bullets

  • Abs Life Time - absolute life time for actor. After that will be erased from scene;
  • Speed - bullet speed;
  • Damage - bullet power.

7. Enemies
