MCT1 Metabolic Cycle Prototype

gistfile1.txt

In the event loop, each cycle do this:

class Player {
  const carbsAbsorptionRate; // how many carbs are absorbed per cycle
  const insulinAbsorptionRate; // how many units of insulin are absorbed per cycle
  const carbsPerInsulinUnit; // how many grams of carbs are metabolise per insulin unit
  const carbsToHealthMagicNumber; // how many carbs convert to 1 unit of player health when metabolised
  const carbsToBGLMagicNumber; // how many carbs convert to one point of BGL when unmetabolised
  const BGLCorrectionPerInsulinUnitMagicNumber; // how many BGL points drop per one unit of insulin without carbs
  carbsOnBoard; // current carbs onboard
  insulinOnBoard; // current insulin onboard
  BGL; // current player BGL
  health; // current player health
}

function doMetabolicCycle(player) {
  let carbsAbsorbed;
  let insulinAbsorbed;
  
  // Absorb carbs
  
  if (carbsOnBoard - carbsAbsorptionRate > 0) {
    carbsAbsorbed = player.carbsOnBoard - player.carbsAbsorptionRate; 
  } else { 
    player.carbsAbsorbed = player.carbsOnBoard; 
  }

  player.carbsOnBoard -= carbsAbsorbed;
  
  // Absorb insulin
  
  if (player.insulinOnBoard - player.insulinAbsorptionRate > 0) { 
    insulinAbsorbed = player.insulinOnBoard - player.insulinAbsorptionRate; 
  } else { 
    insulinAbsorbed = player.insulinOnBoard; 
  }

  player.insulinOnBoard -= insulinAbsorbed;

  // Calculate insulin requirement
  
  let insulinNeeded = (carbsAbsorbed / player.carbsPerInsulinUnit);

  // Calculate and apply insulin and carbs interaction to health
  
  if  (insulinAbsorbed < insulinNeeded) { // BGL will rise
      let carbsConvertedToHealth = player.carbsPerInsulinUnit * insulinAbsorbed;
      let excessCarbs = carbsAbsorbed - carbsConvertedToHealth;
      player.health += carbsConvertedToHealth / player.carbsToHealthMagicNumber; 
      player.BGL = player.BGL + (excessCarbs / player.carbsToBGLMagicNumber);
   }

  if (insulinAbsorbed >= insulinNeeded) { // BGL will be neutral or will drop 
     let carbsConvertedToHealth = carbsAbsorbed * player.carbsToEnergyMagicNumber;
     let excessInsulin = insulinAbsorbed - (carbsConvertedToHealth / player.carbsPerInsulinUnit);
     player.health += carbsConvertedToEnergy;
     player.BGL -= (excessInsulin * player.BGLCorrectionPerInsulinUnitMagicNumber);
