Invasion

Invasion is one of the cleanest examples of a fully structured event pipeline. It combines an opening sequence, a hovering live phase, randomized drop spawning, reward claiming, and end-of-event cleanup, all under a server-driven timeline.

• -UFO follows a scripted opening route into the event space
• -The encounter transitions into a live hover-and-roam phase
• -Drops fall from the UFO into playable areas over time
• -Players collect invasion drops for randomized item rewards

• -Built on a timeline model with opening, drops, cleanup, and end phases
• -Uses a runtime state object to track event IDs, phases, timers, and active drops
• -Procedurally spawns drops inside bounds with TTL expiration
• -Validates pickup range server-side before granting rewards
• -Broadcasts drop spawn, claim, and expiration events to all clients
• -Supports late joins by rebuilding the event state through snapshots
• -Includes explicit cleanup completion signaling for client-side teardown

• -Strong example of server-authoritative event architecture
• -Shows clean separation between presentation phase and gameplay phase
• -Good proof of scalable drop systems, sync handling, and timed event orchestration
