var.monitor

var.monitor is a function that is part of the Var Library.

This function turns on monitoring of a variable (given in the arguments). When another script/program modifies the variable it will trigger on.varChange.

Syntax

var.monitor(varname)
starts monitoring the variable varname (must not be of an exotic type or it will return an error).

Example

function on.create()
	var.monitor("sol")
	--turn monitoring on for the variable "sol"
end

function on.varChange(list)
	--The variable got changed!
	return 0 -- allow the change
end
