Both Players and NPCs have a Variables container for storing variables and information.

By default variables are only stored temporarily and will be lost/reset when the npc dies, player logs out, or the game restarts.

Variable names should use lower camel case. e.g. "in_combat" not "inCombat"

Characters have extension functions to simplify accessing Variables

The following safe version will return false if the value is unset.

val burrow = giantMole["burrow", false]

val burrow: Boolean = giantMole["burrow"]

Setting a value is straight-forward, it's important to use descriptive names to make sure values don't conflict with other content.

giantMole["burrow"] = true

Variables which a player has often need to be sent to the client to change something or display the value. Client variables are split into one of 4 categories:

• varp - Player Variable
• varbit - Variable Bit (part of a varp)
• varc - Client Variable
• varcstr - Client String Variable

Any variables which need storing but don't have a known id should be stored in *.vars.toml

For more details read Runelites page on the subject

These variables will need specifying in the relevant .vars.toml config file in ./data/. Along with their id and type.

[cooks_assistant]     # The string name of the variable
id = 29               # The variable id to send to the cleint
persist = true        # Save the value on logout
format = "map"        # The format the value is stored in (might differ from the format sent to the client)
default = "unstarted" # The default value if left unset
values = { unstarted = 0, started = 1, completed = 2 } # Map for converting values before sending to client
