A script with this logic will outperform a generic auto-clicker by 300% in wave progression. We are already seeing the emergence of "better" scripts that use Computer Vision (CV). Instead of reading game memory (which is detectable), these scripts look at your screen like a human, identify the Upgrade button turning yellow, and click it.

-- 3. Upgrade it to max before touching others if bestUnit and bestUnit.level < 5 then clickUpgrade(bestUnit.position) wait(0.2) elseif coins > 500 then -- 4. Only buy new units if main is maxed buyCheapestUnit() end

wait(1) -- Be human. Don't spam clicks. end

These are nearly undetectable because they emulate a mouse and keyboard via the Windows API, not Roblox's internal engine. If you want the best script, search for "Toy Defense ColorBot" instead of "Toy Defense Script." ColorBots are slower but infinitely safer. Yes—if you do it correctly.
