var.'''monitor''' is a function that is part of the Var Library.
<br>
This function turns on monitoring of a variable (given in the arguments). When another script/program modifies the variable it will trigger [[on.varChange|on.varChange]].<br>
== Syntax ==
var.'''monitor(varname)'''<br> starts monitoring the variable varname (must not be of an exotic type or it will return an error).<br />
See example below.
== Example ==
<source lang="lua">
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
</source>
