so i just started using quest and i want to make a rpg text adventure but i dont know how to make npcs have health or how to make my own health meter also how to take away health from the player and the npc when their in a fight also can i add a turn limit

Elements (the 'physical things' in quest coding or the GUI~Editor):

Game (the Game Object: a special Object for your game's settings)
Objects (the Game Object, Player Objects, Room Objects, Other-Object Objects, or for GameBook quest: Pages)
Verbs
Commands
Functions
Turnscripts
Timers
Object Types
Attributes (but must be within another and different Element)
etc etc etc

Attributes (Data ~ Game Mechanics):

in the GUI~Editor:

via the GUI~Editor's tabs:

'whatever' (Object) -> Attributes (Tab) -> Attribute -> Add ->

( Object Name: 'whatever' )
Attribute Name: 'whatever'
Attribute Type: (String, Integer, Double, Boolean, Script, Object, Lists, Dictionaries, etc)
Attribute Value: ( 'whatever', but based upon the Attribute Type)

via the GUI~Editor's scripting:

run as script -> add new~a script -> variables -> set a variable or attribute -> [EXPRESSION] -> (see below: 'in code' )

In Code:

Object_name.Attribute_name = Value_or_Expression

Examples:

(with simple ' =Values ' )

String Attribute: player.sex = "male"
Integer (int) Attribute: player.strength = 100
Double (Float; Floating Point) Attribute: player.damage = 34.109736
Boolean (True~False Flag) Attribute: orc.dead = false
Object Attribute: game.pov = player

String List Attribute: HK.favorite_colors = split ("black;red" ,";")

Example of (usin an integer attribute with) a complex expression ( ' = Expression ' ):

player.damage = player.weapon.damage + player.weapon.damage * player.strength / 100 - orc.armor.defense - orc.armor.defense * orc.endurance / 100

-----------

Basic Math Computation Expressions, example using a 'strength' Integer Attribute:

Addition:

player.strength = player.strength + 70

Subtraction:

player.strength = player.strength - 90

Multiplication:

player.strength = player.strength * 3

Division:

player.strength = player.strength / 2

--------------

Scripting (actions~events), in code:

msg ("xxx")
msg ("xxx" + Object_name.Attribute_name + "xxx")
if (Object_name.Attribute_name [operator: +, -, *, /, >, <, <=, >=, =, <>] Value_or_Expression) { (scripts) } else if (Object_name.Attribute_name [operator: +, -, *, /, >, <, <=, >=, =, <>] Value_or_Expression) { (scripts) } else { (scripts) }
get input { (scripts) }
show menu { (scripts) }
Object_name.Attribute_name = Value_or_Expression
set (Object_name, "Attribute_name", Value_or_Expression)

----------

the two super scripts, which especially when used together, lets you do 90% of everything that you want to do in your game:

1. the 'set a variable or attribute' Script

in the GUI~Editor:

run as script -> add new~a script -> variables -> 'set a variable or attribute' Script -> [EXPRESSION] -> Object_name.Attribute_name = Value_or_Expression

2. the 'if' Script

in the GUI~Editor:

run as script -> add new~a script -> scripts -> 'if' Script -> [EXPRESSION] -> Object_name.Attribute_name [operator] Value_or_Expression
