Suck Function - Direction & Wrapping Fixes Applied ✅#

🔧 Major Fixes Applied:#

✅ Corrected Direction Logic#

• FIXED: direction = suckAccumulator > 0 ? 1 : -1
• Positive values (suck 1) = inward motion toward center ✅
• Negative values (suck -1) = outward motion away from center ✅
• Direction now works intuitively as expected!

✅ Fixed Wrapping for True Circulation#

• FIXED: srcDistance = distance - (direction * displacementSteps)
• Proper modulo wrapping using while loops for complete circulation
• True wrap-around: pixels that move past edges emerge from opposite side
• No more incomplete circulation - patterns will fully reset and flow

✅ Pixel-Perfect Preservation#

• Nearest neighbor sampling only - no blur from interpolation
• Discrete integer steps prevent fuzzy artifacts
• No center holes - minimum radius prevents burning
• Lossless pixel copying with direct RGBA transfer

🌊 True Circulation Behavior:#

1. Inward Flow (suck 1): Pixels move toward center, wrap to outer edges
2. Outward Flow (suck -1): Pixels move away from center, wrap from edges
3. Complete Reset: Patterns will eventually return to original state through wrapping
4. Continuous Evolution: Each frame builds on previous for living animation

🎯 Fixed Control:#

• (suck 0.5) - Gentle inward spiral ✅
• (suck 1) - Moderate inward vortex ✅
• (suck -0.5) - Gentle outward expansion ✅
• (suck -1) - Moderate outward flow ✅

🎨 Clean Results:#

• Sharp, pixel-perfect motion with no blur
• True directional control that matches intuition
• Complete circulation where inside becomes outside
• Reversible effects that can return to original state

🧪 Test Commands:#

Try these to verify the fixes:

• (suck 1) followed by (suck -1) - should work in opposite directions correctly!
• (s0.1 (suck 0.5)) - continuous inward spiral
• (s0.1 (suck -0.5)) - continuous outward expansion

The suck function should now behave exactly as intended with proper directionality and true circulation! 🌪️✨
