Unity Game Tutorial: Galaga 3D

Create a quadratic Bezier curve tool to interpolate between three points in world space, using a time parameter t to generate a point along the curve.

Implement enemy movement along a path by updating the current waypoint id when the next point is reached, handling busy curve vs non-busy paths with waypoint lists in Unity.

Define a formation grid in Unity to position enemy ships, using grid size and offsets with a center to left then left-right filling pattern visualized by gizmos and editor labels.

Tune and align Unity Galaga 3D enemy formations by adjusting left–right movement, grid dividers, and the boss and wasp layouts for consistent speed and placement.

Define a state machine for enemy behavior in a Unity Galaga 3D tutorial, moving from fly in to on path, then into formation using an enum and switch logic.

Spawn waves 2 explains spawning enemies in a Unity Galaga 3D scene by instantiating fly prefabs, assigning paths and formations, and controlling timing with a coroutine and wait intervals.

Create enemy ship prefabs with a common behavior, add wasps and a boss ship to the formation, and tune spacing and scale via the spawn manager for smooth waves.

Implement mouse drag to move the player ship in 3D by converting screen points to world coordinates and applying an offset. Disable gravity on the rigidbody during dragging.

Define bullet spawn points on the player ship, instantiate bullets along the forward axis, and implement a fire rate system with upgradeable bullet count to shoot multiple bullets.

Set bullets to self-destruct after a short delay and use a boundary cube as a wall to destroy bullets when they reach the edge, keeping the playfield clear.

Automate spreading by using a spawn manager to track all enemies in a public list, monitor each enemy state with timed checks, and start spread routines when all are idle.

Implement a UI script that connects UI canvas text fields for score, lives, and stage, updates them in real time, and exposes a static instance for global access.

Implement the win state by incrementing the level and reloading the active scene with Unity scene management, preserving score and lives for the next stage.
