Common Achievement Patterns

Core Achievement Checking

-- Check basic achievement unlock status
local achievements = require("achievements")
local achievement = achievements[1] -- survive_20

-- Platform-specific ID access
local steam_id = achievement.id.steam    -- "1_survive_20"
local psn_id = achievement.id.psn        -- 1

Event Achievement Management

-- Create and configure event achievements
local event_achievements = EventAchievements()

-- Load event data
local event_data = {
    eventid = "winter_feast",
    seasons = {"winter"},
    achievements = {
        {
            name = "Daily Challenges",
            data = {
                {achievementid = "daily_1", daily = true},
                {achievementid = "event_1", daily = false}
            }
        }
    }
}
event_achievements:LoadAchievementsForEvent(event_data)

-- Check completion status
local is_unlocked = event_achievements:IsAchievementUnlocked("winter_feast", "winter", "daily_1")

Community Progression Tracking

-- Initialize community progression
local progression = CommunityProgression()
progression:RegisterForWorld()

-- Check unlock status
if progression:IsUnlocked("trails") then
    -- Content is available
end

-- Request updated data
progression:RequestAllData(false, TheNet:GetUserID())

Achievement System Dependencies

Required Systems

• Data Management: Achievement data persistence and loading
• Networking: Server synchronization and platform integration
• User Interface: Achievement display and notification systems

Optional Systems

• Character Systems: Character-specific achievement requirements
• Game Mechanics: Enhanced gameplay-based achievement triggers
• World Systems: Environmental achievement conditions

Performance Considerations

Memory Usage

• Core achievements use minimal memory with static definitions
• Event achievements load data on-demand for active events only
• Community progression caches server data with expiration timers
• Achievement progress tracking uses efficient delta updates

Performance Optimizations

• Achievement validation uses fast lookup tables and caching
• Event achievement checking batches related conditions
• Community progression requests use intelligent retry logic
• Platform integration minimizes API calls through batching

Scaling Considerations

• Systems support multiple simultaneous events and seasons
• Achievement complexity scales with available content variety
• Community progression handles large-scale server synchronization
• Platform integration supports diverse achievement structures

Development Guidelines

Best Practices

• Always validate achievement conditions before marking as complete
• Use consistent achievement ID naming conventions across all systems
• Implement proper error handling for network-dependent achievements
• Design achievement structures to be event-agnostic where possible
• Test achievement systems with various network conditions and edge cases

Common Pitfalls

• Not validating server responses for community progression data
• Creating achievements that conflict between different event systems
• Bypassing achievement validation during development without proper flags
• Implementing achievements that don't handle multiplayer edge cases
