🐛 Critical hit system subtracting instead of adding

Help! I’m working on a clicker game and my critical hit system is completely broken. Instead of giving bonus clicks, it’s actually subtracting clicks from my total! 😭

The weird part is:

  • Normal clicks work fine
  • Critical hits trigger correctly (visual effects show)
  • But somehow the score goes DOWN instead of up
  • Sometimes it even divides the score by itself?

I’ve been staring at this code for hours and can’t figure out what’s wrong. Has anyone seen this before?

I’ve seen this exact bug before @ClickerDev_Pro! This is a classic case of conflicting scripts and variable scope issues. Let me walk you through the debugging process:

🔍 Common Critical Hit Bug Patterns

Here’s what usually causes this issue:

flowchart TD A[🖱️ Player Clicks] --> B{Critical Hit?} B -->|No| C[Normal Click Script] B -->|Yes| D[Critical Hit Script] C --> E[✅ Add Normal Points] D --> F[❌ Bug Zone] F --> G{Common Issues} G -->|Issue 1| H[Both Scripts Running] G -->|Issue 2| I[Wrong Variable Used] G -->|Issue 3| J[Math Error] H --> K[Normal: +1<br/>Critical: -2<br/>Result: -1] I --> L[Using Multiplier<br/>Instead of Score] J --> M[Division Instead<br/>of Multiplication] E --> N[✅ Score Increases] K --> O[❌ Score Decreases] L --> O M --> O style A fill:#e1f5fe style E fill:#e8f5e8 style F fill:#ffebee style O fill:#ffcdd2 style N fill:#c8e6c9

🛠️ Step 1: Check for Duplicate Scripts

The most common issue is having both normal and critical scripts running simultaneously:

❌ Problematic Code Pattern:
    when this sprite clicked
if <(pick random (1) to (10)) = [1]> then
// Critical hit code
change [score v] by [10]
broadcast [critical hit v]
else
// Normal click code  
change [score v] by [1]
end

// PROBLEM: Another script also running!
when this sprite clicked
change [score v] by [-1]  // This cancels out the critical!

✅ Step 2: Proper Critical Hit Implementation

Here’s the correct way to implement critical hits:

    when this sprite clicked
set [click value v] to [1]  // Default click value

// Check for critical hit
if <(pick random (1) to (100)) ≤ [10]> then  // 10% crit chance
set [click value v] to [5]  // 5x multiplier
broadcast [critical hit effect v]
play sound [critical sound v]
end

// Apply the click value
change [score v] by (click value)
change [total clicks v] by [1]

🔧 Step 3: Debug Variable Conflicts

Check if you’re accidentally using the wrong variables:

🔍 Variables to Check:
• score vs clicks vs multiplier
• Make sure you’re changing the right variable
• Check if any scripts are resetting variables unexpectedly

🧮 Step 4: Fix Math Operations

Sometimes the issue is using division instead of multiplication:

    // ❌ WRONG - This divides!
change [score v] by ((score) / [2])

// ✅ CORRECT - This multiplies!
change [score v] by ((click value) * [2])

🎯 Step 5: Isolate and Test

Create a simple test to isolate the problem:

    // Test script - put this alone on a sprite
when this sprite clicked
say (join [Score before: ] (score)) for [1] seconds
change [score v] by [10]  // Test with fixed value
say (join [Score after: ] (score)) for [1] seconds

This will help you see exactly what’s happening to your score! 🎯

@DebugMaster_Alex OMG you’re a lifesaver! 🎉

It was exactly what you said - I had TWO scripts running on click! One was adding the critical hit bonus, but another old script was subtracting 1 every time. I completely forgot about that old debugging script I left in there.

Fixed it and now my critical hits work perfectly! Thank you so much! 🚀

This is such a common bug! 😅 Here are some pro tips to avoid this in the future:

  • 🧹 Clean up old scripts: Always delete test/debug scripts when done
  • 📝 Use comments: Label your scripts so you remember what they do
  • 🔍 Use the debugger: Watch variables in real-time to catch issues
  • ✅ Test incrementally: Test each feature before adding the next

Happy clicking! 🖱️✨
