📋 Need help with collectibles menu system

I’m working on a Pokemon-style collection game where players can collect various items and creatures. I want to create a scrollable menu that shows all collected items, but I’m running into issues with the scrolling mechanics! 🎮

The problems I’m facing:

  • Clones all show the same data from the list
  • Scrolling messes up the positioning
  • Can’t figure out how to make each clone unique
  • Menu doesn’t respond properly to clicks

Has anyone successfully created a scrolling collectibles menu? I’d really appreciate some guidance! 🙏

Great question @CollectionMaster_99! I’ve built several collection systems like this. The key is using unique IDs for each clone and proper scroll calculations. Here’s the complete solution:

📊 Menu System Architecture

Here’s how a scrollable collectibles menu works:

flowchart TD A[🚀 Menu Opens] --> B[Create Clones for Items] B --> C[Assign Unique IDs] C --> D[🎮 Menu Loop] D --> E{User Scrolls?} E -->|Yes| F[Update Scroll Value] E -->|No| G{User Clicks Item?} F --> H[Recalculate Positions] H --> I[Update Clone Positions] I --> D G -->|Yes| J[Get Clicked Item ID] G -->|No| D J --> K[Show Item Details] K --> L[Perform Action] L --> D D --> M{Menu Closed?} M -->|No| E M -->|Yes| N[Hide All Clones] style A fill:#e1f5fe style K fill:#e8f5e8 style N fill:#ffebee

🔧 Step 1: Menu Setup and Variables

First, create the necessary variables for the menu system:

    when flag clicked
set [collectibles menu opened v] to [no]
set [scroll v] to [0]
set [menu top edge v] to [150]
set [item height v] to [60]
hide

📋 Step 2: Clone Creation with Unique IDs

Create clones for each item in your collection:

    // Main collectibles sprite
when flag clicked
hide
set [id v] to [0]

// Create a clone for each collectible
repeat until <(id) > (length of [collectibles v])>
change [id v] by [1]
create clone of [myself v]
end

// Clone initialization
when I start as a clone
set [my id v] to (id)
forever
if <(collectibles menu opened) = [yes]> then
show

// Set costume based on item type
switch costume to (item (my id) of [collectibles v])

// Calculate position with scroll offset
set [base y v] to (((menu top edge) + ((costume height) / [2])) - ((my id) * (item height)))
go to x: [0] y: ((base y) + (scroll))

// Hide if outside menu bounds
if <<(y position) > [180]> or <(y position) < [-180]>> then
hide
else
show
end
else
hide
end
end

🎮 Step 3: Menu Controls and Scrolling

Handle menu opening/closing and scrolling:

    // Menu control (main sprite)
when this sprite clicked
if <(costume [name v]) = [menu icon]> then
if <(collectibles menu opened) = [yes]> then
set [collectibles menu opened v] to [no]
else
set [collectibles menu opened v] to [yes]
set [scroll v] to [0]  // Reset scroll when opening
end
end

// Scroll controls
when key [up arrow v] pressed
if <(collectibles menu opened) = [yes]> then
if <(scroll) < [200]> then  // Limit scroll range
change [scroll v] by [30]
end
end

when key [down arrow v] pressed
if <(collectibles menu opened) = [yes]> then
if <(scroll) > (0 - ((length of [collectibles v]) * (item height)))> then
change [scroll v] by [-30]
end
end

🖱️ Step 4: Item Selection and Actions

Handle clicking on individual items:

    // In clone script
when this sprite clicked
if <(collectibles menu opened) = [yes]> then
// Make sure this is a clone, not the original
if <not <(costume [name v]) = [menu icon]>> then

// Get the item data
set [selected item v] to (item (my id) of [collectibles v])
set [selected item name v] to (item (my id) of [item names v])
set [selected item description v] to (item (my id) of [item descriptions v])

// Show item details
broadcast [show item details v]

// Play selection sound
play sound [menu select v]
end
end

🚀 Step 5: Advanced Features

Add categories and search functionality:

    // Category filtering
when I receive [filter by category v]
if <(item (my id) of [item categories v]) = (selected category)> then
show
else
hide
end

// Search functionality
when I receive [search items v]
if <(item (my id) of [item names v]) contains (search text)?> then
show
else
hide
end

// Smooth scrolling animation
define smooth scroll to (target)
repeat until <(abs ((scroll) - (target))) < [2]>
change [scroll v] by (((target) - (scroll)) / [5])
wait [0.02] seconds
end
set [scroll v] to (target)

💡 Pro Tips for Better Menus

  • Performance: Only show clones that are visible on screen
  • Visual feedback: Add hover effects and selection highlights
  • Accessibility: Support both mouse and keyboard navigation
  • Data organization: Use separate lists for names, descriptions, and categories

This system works great for Pokemon-style collections, inventory systems, and any scrollable menu! The key is giving each clone a unique ID and calculating positions relative to the scroll offset. 🎯

@UIExpert_Sarah This is absolutely perfect! 🎉 The unique ID system was exactly what I was missing!

I implemented your solution and now my collectibles menu works flawlessly! The scrolling is smooth, each item displays correctly, and the click detection works perfectly. My Pokemon collection game is finally complete! 🎮✨

Thank you so much for the detailed explanation and code examples! 🙌

Excellent solution! I’d like to add a tip for making the menu even more user-friendly: 🎨

    // Add visual feedback for hovering
when I start as a clone
forever
if <touching [mouse-pointer v]?> then
set [brightness v] effect to [20]
set size to [110] %
else
clear graphic effects
set size to [100] %
end
end

This creates a nice hover effect that makes the menu feel more responsive! Also consider adding sound effects for scrolling and selection. 🔊
