• sci-fi props variety;
• 5 types animated turrets (models);
• 2 types enemies (models);
• turret gameplay: search target, aim, fire;
• turrets setup: fire rate, aim time, search radius (via response area);
• bullet gameplay: target hit;
• bullet setup: fly speed, damage;
• explode effect (particle based);
• enemy gameplay: direct fly from spawner;
• enemy setup: fly speed, health (armor);
• realized gameplay: turret fire -> enemy hit -> enemy destroy;
• red-hot turret barrel effect (long fire time makes red-hot turret barrel; idle - cold barrel);
• colorful bullets (see video preview);
• enemy spawner;
• utilized Unity engine physics;
• textures 4K;
• 100-5000 tris;
• LOD's.

2. Setup

• Click download package via your Asset Store;
• Import to any project:

3. Simple Gameplay (Principled)

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

• Drag and drop to your own scene prefab Response Area, stored here: \UnderSiege\Prefab\_System
• Drag and drop any turret (Turret3 for example) from \UnderSiege\Prefab\_Turret
• Turret must be placed inside Response Area wire sphere
• Make new empty gameobject (Ctrl+Shift+N)
• Add component USTraffic on it:

• Add Enemy prefabs from \UnderSiege\Prefab\_Enemy to vehicle array variety
• Right click on created gameobject - create empty:

• Adjust direction for new (child) gameobject. Make sure this gameobject directs to response area wire sphere.
• Something like this:

• Principled action ready. Hit play for preview.

4. Response Area

Response Area prefab is a primary service gameobject for turrets and for enemy ships. Details:

• Any turret must be placed inside ResponseArea wire sphere for correct working;
• Any enemy ship fly through Response Area becomes a target of a turret (random order for multi targets);
• Response areas may be overlapped. Response order by internal Unity engine calculations.
• Params:

• Enemy Layer - all enemy ships must belong to this layer;
• Turret Layer - all turrets must belong to this layer;
• Trigger Sphere Radius - response area trigger radius;
• Collect Rate - enemy targets detect update rate (in seconds). No need to change this param in most cases.

5. Turrets

There are 5 turrets types (models):

• Down Turret - tick for bottom turret placement;
• Aim speed - movement speed for turrets heads (look at current target);
• Fire Rate - fire speed in seconds (lower values = faster);
• Bullet - bullet prefab (no need to change by default).

• Emissive String - replace with '_EmissiveColor' for HDRP usage.

6. Bullets

There are some bullets for turrets types:

• Abs Life Time - absolute life time for gameogject. After that will be erased from scene;
• Speed - bullet speed;
• Damage - bullet power;
• Interact Layer - layer for target (enemy ship).

7. Enemies

There are 2 types of enemies (models):

• Health - health (armor) for the ship;
• Speed - movement speed;
• Abs Life Time - absolute life time for actor. After that will be erased from scene.

8. Layers

• set response layer for turret and for enemy ship;
• see Response Area prefab:

9. Enemy spawner

• Make new empty gameobject (Ctrl+Shift+N)
• Add component USTraffic on it
• Add Enemy prefabs from \UnderSiege\Prefab\_Enemy to vehicle array variety
• Right click on created gameobject - create empty (child) = spawn point
• Duplicate child gameobject - adjust position and rotation
• All children gameobjects = spawn points.

• maximum vehicle in scene - maximum count of enemy gameobjects;
• spawn frequency min/max time - enemy spawn freq. in seconds;
• start position scatter - scatter position for new enemy ship;
• vehicle variety array - add here enemy prefabs (for your own custom refabs: each prefab must contain: USEnemyShip.cs script, collider, game object layer = Response Area enemy layer);
• speed variety - enemy speed scatter.
