🌐 Online player counter issues

Hey everyone! I’ve created an online clicker game and I’m trying to implement a real-time player counter to show how many people are currently playing. I’ve tested it with multiple users but the counter doesn’t seem to update correctly.

What I need help with:

  • Accurate real-time player count display
  • Proper player join/leave detection
  • Handling connection timeouts and disconnections

The game is fully functional otherwise, but the social aspect of seeing other players online would really enhance the experience. Any multiplayer experts who can help? 🎮

Great question @MultiplayerDev_Pro! Online player counters can be tricky. Let me show you a robust solution:

🌐 Player Counter System Flow

Here’s how a reliable online player counter should work:

flowchart TD A[🎮 Player Joins Game] --> B[Generate Unique Player ID] B --> C[Register Player in Cloud] C --> D[Start Heartbeat System] D --> E[Send Heartbeat Every 5s] E --> F[Update Player Timestamp] F --> G{Still Playing?} G -->|Yes| E G -->|No| H[Player Leaves/Disconnects] H --> I[Remove from Active List] I --> J[Update Player Count] K[Background Cleanup] --> L[Check All Player Timestamps] L --> M{Timestamp > 15s old?} M -->|Yes| N[Remove Inactive Player] M -->|No| O[Keep Player Active] N --> P[Update Count Display] O --> P P --> Q[Wait 10 seconds] Q --> K style A fill:#e1f5fe style C fill:#f3e5f5 style E fill:#fff3e0 style I fill:#ffebee style P fill:#e8f5e8

🔧 Step 1: Player Registration System

First, create a unique player ID and register the player:

    when flag clicked
set [my player id v] to (join (username) (join [-] (pick random (1000) to (9999))))
set [☁ player list v] to (join (☁ player list) (join (my player id) [|]))
set [☁ player count v] to ((length of (☁ player list)) / [20])
broadcast [start heartbeat v]

💓 Step 2: Heartbeat System

Keep the player’s presence alive with regular heartbeats:

    when I receive [start heartbeat v]
forever
// Update player timestamp
set [current time v] to (days since 2000)
set [☁ heartbeat v] to (join (my player id) (join [:] (current time)))

// Wait 5 seconds before next heartbeat
wait (5) seconds
end

🧹 Step 3: Cleanup System

Remove inactive players automatically:

    when flag clicked
wait (2) seconds
forever
set [current time v] to (days since 2000)
set [active players v] to []
set [player data v] to (☁ player list)

// Check each player's last heartbeat
repeat until <(length of (player data)) < [1]>
set [player entry v] to (item (1) of (split (player data) by [|]))

if <(length of (player entry)) > [0]> then
set [player id v] to (item (1) of (split (player entry) by [:]))
set [last seen v] to (item (2) of (split (player entry) by [:]))

// If seen within last 15 seconds, keep active
if <((current time) - (last seen)) < [0.000174]> then
set [active players v] to (join (active players) (join (player entry) [|]))
end
end

set [player data v] to (join (all but first of (split (player data) by [|])) [])
end

// Update cloud variables
set [☁ player list v] to (active players)
set [☁ player count v] to (length of (split (active players) by [|]))

wait (10) seconds
end

📊 Step 4: Display System

Show the player count with a nice visual:

    when flag clicked
forever
set [display count v] to (☁ player count)

// Create visual display
clear
set pen color to (#00ff00)
set pen size to (3)

// Draw online indicator
go to x: [-200] y: [150]
pen down
repeat (4)
move (20) steps
turn right (90) degrees
end
pen up

// Show count text
go to x: [-180] y: [140]
set [display text v] to (join [🌐 Online: ] (display count))

wait (1) seconds
end

🛡️ Step 5: Error Handling

Handle connection issues gracefully:

    define handle connection error
if <(☁ player count) = []> then
set [☁ player count v] to [1]
end

if <(☁ player list) = []> then
set [☁ player list v] to (join (my player id) [|])
end

// Check if cloud variables are working
set [☁ test connection v] to [1]
wait (0.2) seconds
if <not <(☁ test connection) = [1]>> then
set [connection status v] to [offline]
set [display count v] to [Offline Mode]
else
set [connection status v] to [online]
end

🎯 Step 6: Player Leave Detection

Properly handle when players leave:

    when flag clicked
forever
if <key (space v) pressed?> then
// Manual leave
broadcast [player leaving v]
stop [all v]
end
end

when I receive [player leaving v]
// Remove player from list
set [updated list v] to []
repeat (length of (split (☁ player list) by [|]))
set [player entry v] to (item (counter) of (split (☁ player list) by [|]))
if <not <(player entry) contains (my player id)>> then
set [updated list v] to (join (updated list) (join (player entry) [|]))
end
end
set [☁ player list v] to (updated list)
set [☁ player count v] to (length of (split (updated list) by [|]))

This system provides accurate, real-time player counting with automatic cleanup! 🎉

@OnlineCounter_Expert This is exactly what I needed! 🙌

I implemented the heartbeat system and the player counter is now working perfectly. The automatic cleanup is brilliant - no more ghost players showing as online!

Quick question: Is there a way to show player names instead of just the count? Like a “Who’s Online” list?

@MultiplayerDev_Pro Absolutely! Here’s how to create a “Who’s Online” display:

    define show online players
clear
set [y position v] to [150]
set [player list v] to (☁ player list)

repeat (☁ player count)
set [player name v] to (item (1) of (split (player list) by [:]))

// Display player name
go to x: [-200] y: (y position)
set [display text v] to (join [👤 ] (player name))

change [y position v] by [-25]
set [player list v] to (join (all but first of (split (player list) by [|])) [])
end

This creates a scrolling list of all online players! Perfect for community building! 👥
