# Adding medications *Advanced Roleplay Environment supports modular medications. This means you can easily add medications or edit them accordingly.* ## Adding medications In order to add a medication we just need to add the medication inside the medications file and configure the properties accordingly. ### Adding the medication Since all medications are saved inside `script/entities/medications.lua`, we will open this file. This should look like this:

Now we will scroll to the bottom and just copy a medication from above and edit it to our needs so it should look like this:

### Configuring the medication There are many options available for us to configure the medication perfectly to our needs.

Option	Description	Example
painReduce	This property is a number and contains the value of how much the pain get reduced.	`painReduce = 0.3` The pain get reduced by 0.3 * `effectRatio` per second.
hrIncreaseLow	This property is a table contains a table { minIncrease, maxIncrease } how much the heart rate will increase or decrease if the heart rate is below 55 bpm.	`hrIncreaseLow = { -10, 10 }` The heart rate will in minimum decrease by 10 or in maximum increase by 10 if the heart rate is below 55 bpm.
hrIncreaseNormal	This property is a table contains a table { minIncrease, maxIncrease } how much the heart rate will increase or decrease if the heart rate is >= 55 bpm and <= 110 bpm.	`hrIncreaseNormal = { 5, 20 }` The heart rate will in minimum increase by 5 and in maximum by 20 if the heart rate is >= 55 bpm and <= 110 bpm.
hrIncreaseHigh	This property is a table contains a table { minIncrease, maxIncrease } how much the heart rate will increase or decrease if the heart rate is > 110 bpm	`hrIncreaseHigh = { 2, 7 }` The heart rate will in minimum increase by 2 and in maximum by 7 if the heart rate is above 110 bpm.
timeInSystem (maxTimeInSystem)	This property is a number and contains the value how long a medication is kept in the system before removing it. Also it will be used to calculate the effect ratio. (in seconds)	`timeInSystem = 1800` The medication is kept 1800 seconds in system before removing it. Calculation for the effect ratio: `effectRatio = min((timeInSystem / timeTillMaxEffect) ^ 2, 1) * (maxTimeInSystem - timeInSystem) / maxTimeInSystem` To understand the effect ratio formula we need to define the values where: - timeInSystem is variable and describes the current time in the system in seconds. - timeTillMaxEffect is a constant and describes the time till the effect ratio reaches 1. - maxTimeInSystem is a constant and describes how long the medication will stay in the system until it reaches 0.0 effect ratio at the end. - min(valueA, valueB) will always return the lowest value of both so if valueA is 5 and valueB is 8 it will return 5. In our example it is a calculation and 1 so it will always be less <= 1.
timeTillMaxEffect	This property is a number and contains the value when the max effect ratio is reached. (in seconds)	`timeTillMaxEffect = 30` The medication will reach its max effect after 30 seconds so a effect ratio of 1.
maxDose	This property is a number and contains the value after how many medications in system the function `onOverDose` will be triggered.	`maxDose = 5` The property onOverDose will be triggered after 5 times of injection of this medication.
onOverDose	This property is a function and will be triggered if the number of the same medication in the system is >= `maxDose`	`onOverDose = function()` `print("hello!")` `end` The function will print "hello" after this function has been triggered.
viscosityChange	The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal concept of "thickness". This value will increase/decrease the viscoty of the blood with the percentage given. Where 100 = max. Using the minus will decrease viscosity.	`viscosityChange = -10` The peripheral resistance will reduce by maximum 10 and `viscosityChange * effectRatio` per second.
