🖱️ Need help with stamping sprites

Hi everyone! I just became a Scratcher and this is my first post! 🎉 I’m trying to create a project where I can stamp sprites every time I click the mouse, but I’m not sure how to do it.

Can someone help me understand how to make this work? I want to create cool patterns and designs by clicking around the screen!

Welcome to Scratch, @ScratchNewbie_Pink! 🎉 Great first question! Stamping is a really fun feature. Here’s how to create a stamping effect when you click:

🎨 Stamping System Flow

Here’s how the stamping system works:

flowchart TD A[🚀 Project Start] --> B[Position Sprite] B --> C[🎮 Main Loop] C --> D{Mouse Clicked?} D -->|Yes| E[🖱️ Move to Mouse Position] D -->|No| C E --> F[📍 Stamp at Current Position] F --> G[✨ Optional: Add Effect] G --> H[🔄 Wait for Next Click] H --> C C --> I{Project Running?} I -->|Yes| D I -->|No| J[🏁 End] style A fill:#e1f5fe style E fill:#f3e5f5 style F fill:#e8f5e8 style G fill:#fff3e0 style J fill:#fce4ec

🔧 Method 1: Basic Click Stamping

Here’s the simplest way to stamp when you click:

    when flag clicked
forever
if <mouse down?> then
go to (mouse x) (mouse y)
stamp
wait until <not <mouse down?>>
end
end

🎯 Method 2: Single Click Stamping

If you want to stamp only once per click (not continuously while holding):

    when flag clicked
forever
wait until <mouse down?>
go to (mouse x) (mouse y)
stamp
wait until <not <mouse down?>>
end

🌟 Method 3: Advanced Stamping with Effects

For a more exciting stamping experience:

    when flag clicked
forever
wait until <mouse down?>
go to (mouse x) (mouse y)

// Add some visual flair
set [color v] effect to (pick random [0] to [200])
set [size v] to (pick random [50] to [150])

stamp

// Play a sound
play sound [pop v]

// Reset effects
clear graphic effects
set size to [100] %

wait until <not <mouse down?>>
end

🎨 Method 4: Different Stamps with Keys

Create different stamp types using keyboard keys:

    when flag clicked
forever
if <mouse down?> then
go to (mouse x) (mouse y)

if <key [1 v] pressed?> then
switch costume to [stamp1 v]
end
if <key [2 v] pressed?> then
switch costume to [stamp2 v]
end
if <key [3 v] pressed?> then
switch costume to [stamp3 v]
end

stamp
wait until <not <mouse down?>>
end
end

🧹 Bonus: Clear All Stamps

Add this code to clear all stamps when you press the space key:

    when [space v] key pressed
clear

💡 Pro Tips:

Costume Design: Create different costumes for your sprite to make various stamp shapes
Size Variation: Use random sizes to make stamping more interesting
Color Effects: Add color effects before stamping for variety
Sound Effects: Add sounds to make stamping more satisfying
Stamp Trails: Try stamping while moving for trail effects

Have fun creating amazing stamp art! 🎨✨
