identifyall was solely added as an atcommand, wasn't it?
I made this as a script-command based on reiterations of identify() so users could make an inline function in their quest, event, or utility scripts.
The benefits are trivial and would mostly suit low-rate servers with a low zeny pool, but they're beneficial nonetheless. ¯\_(ツ)_/¯
This script-command version of identifyall() provides the following:
A return value for the number of items identified
Enables the possibility of using the amount of items identified to create individual cost or bulk pricing
i.e. 10 items identified for 400 Z (base cost for 10x items identified @ 40 Z each)
i.e. 23 items identified for 805 Z (bulk cost for 23x items identied @ 35 Z each, when identifying 20 or more at once)
Allows for the number of items identified (and the maths on cost) to be displayed to the user, for informational purposes
Eliminates redundant scripting by alternatively using atcommand "@identifyall"; in a script and still needing to gather the number of items identified
Allows for use of identifyall as a script-command rather than an atcommand, particularly under circumstances when using atcommands in general are restricted, limited, or undesirable
With some modification, this can be changed into a global function so it can be used across multiple scripts
With a little imagination and creativity, identifyall as a script-command can be used for interfacing with various utilities, zeny sinks, and other features. Like I said -- this little script command would find its niche mostly in low-rate servers, but it'll be here if it's needed.
