Space Rock Shooter Template

Space Rock Shooter Template is a complete Blueprint game template for a top-down asteroid shooter. Fly a spaceship inside a bounded play area, destroy rocks for score, pick a cannon loadout, and chase a persistent high score.

The project ships as a standalone Unreal project. All gameplay lives under Content/SpaceShooterTemplate/.

  participant GM as BP_SpaceRockGameMode
  participant Ship as BP_Spaceship
  participant Rock as BP_SpaceRock
  HUD->>GM: Start Game (cannon type)
  GM->>Ship: Set Cannon Type + Start Spaceship

  loop While Current Asteroids < Max
    GM->>Rock: Spawn at screen edge
  end
  Ship->>Rock: Projectile hit
  Rock->>GM: Add Score
  Ship->>Ship: On Component Hit (lose life)
  GM->>HUD: Game over tab

1. Start screen — cannon selection (SingleShot / TripleShot), high score, lives.
2. Start game — Start Spaceship, Start Asteroid Spawn, HUD switches to in-game tab.
3. Play — thrust/rotate, fire; rocks and ship wrap at play bounds.
4. Score — rock destruction calls Add Score; WBP_HitDamage shows points.
5. Lives — default Spaceship Lives = 3; zero lives triggers game over.
6. Restart — Restart Game resets the session; high score saves via BP_SaveGameManager.
