📖 The mission

Today you unlock

Cap a value

Game stats often have a maximum. First add the potion to the health, then stop the result at 100 so overhealing never goes too high.

💡 Hint ladder

Add them first: local newHealth = health + potion
if newHealth > 100 then return 100 end
math.min(health + potion, 100) does it in one line!

🧪 Coach checks

Getting ready

💬 math.min picks the smaller of two numbers — great for capping things.

print(math.min(80, 100))    -- 80  (80 is smaller)
print(math.min(120, 100))   -- 100 (never above the cap!)

function addCoins(coins, found)
  return coins + found
end

print(addCoins(50, 30))     -- 80
