I am having trouble getting to set up a database veriable within a class from a trigger. The help files never mention how to set one up in a class.

My trigger seems to create the variables fine, however it assumes its just a string list as opposed to a data record. When i went into the settings editor i noticed that the variable auto checks the 'use default value' checkbox even though there is no default value given... once i uncheck this box i can save it as a data record...

#CLASS {Utility|Skins}
#TRIGGER {You ask the furrier if he would like to buy {a|an} (*).} {
#VAR temp {%replace( %1, " ", "_")}
#VAR temp2 {@@temp}
}
#COND {The furrier takes the *, appraises it minutely, then pays you (%d) silvers.} {#IF (%null( @temp2)) {
#VAR @temp {Max=%1|Min=%1} {} {Utility|Skins}
#EC New skin type recorded: @temp
} {
#EC Now we can test for Min/Max!
#IF (%1 > @temp.Max) {#ADDKEY @temp Max %1}
#IF (%1 < @temp.Min) {#ADDKEY @temp Min %1}
}} {within|param=1}
#CLASS 0

PS. once i got the variable properly saved i looked at the 'class script' again and notice that the syntax used to display the database variable is nothing like how the help files say to create it:

#VAR viper_fang {Max528Min148}

PPS. when i displayed it another way it appears in yet a third syntax (#VAR with no parameters):

viper_fang Max<30>528<29>Min<30>148

Try:
#VAR @temp {Max=%1|Min=%1} _nodef {Utility|Skins}

#VAR @temp {Max=%1|Min=%1} _nodef {Utility|Skins}
this is just some filler material ok everyone^ syntax error

It did still correctly save the variable to the class. The issue remains that it is a 'string list' upon creation and not a 'data record'.

Add to the value of your trigger:

#IF (!%defined(@temp)) {#VAR @temp {} _nodef "utility|skins"}
#ADDKEY @temp {Max=%1|Min=%1}

ie. Lets check to see if it exists, if not create it.
Then use #ADDKEY to force data record.

Edit:
Probably a better check; takes into account the folder, something like

#VAR temp tester2
#VAR temp2 ./utility/skins/@temp
#IF (%null(@{@{temp2}})) {#VAR @temp {} _nodef "utility|skins"}

#VAR @temp2 %addkey(@{@temp},Min,%1)
#VAR @temp2 %addkey(@{@temp},Max,%1)

I finally got it to work with the following code:

#CLASS {Utility|Skins}
#ALIAS testfur {#EC You ask the furrier if he would like to buy a test fur.;#EC The furrier takes the test fur, appraises it minutely, then pays you %1 silvers.}
#VAR test_fur {Max765Min45}
#TRIGGER "skinvalue" {You ask the furrier if he would like to buy {a|an} (*).} {
#VAR temp {%replace( %1, " ", "_")}
#VAR temp2 {@@temp}
}
#COND {The furrier takes the *, appraises it minutely, then pays you (%d) silvers.} {#IF (%null( @temp2)) {
#VAR @temp {} _nodef "utility|skins"
#ADDKEY @temp Max %1
#ADDKEY @temp Min %1
#EC New skin type recorded: @temp
} {
#IF (%1>%db( @{@temp}, Max)) {
#EC Increased profit by %exec( %1-%db( @{@temp}, Max)).
#ADDKEY @temp Max %1
}
#IF (%1<%db( @{@temp}, Min)) {
#EC Sales are down by %exec( %db( @{@temp}, Min)-%1).
#ADDKEY @temp Min %1
}
}} {within|param=1}
#CLASS 0

However there seems to be a small issue with the #ECHO lines, I am getting this output:

Increased profit by 755-745.
Sales are down by 45-545.

Any ideas?

Try %eval vs %exec?

That did it, thanks alot... now to put it to use.

One other thing, is there a way i can force the trigger back to its initial state if the object i try to sell isn't a skin? (Set into another trigger of course.)

#TR {The furrier frowns and says "I haven't a clue, &Me. I only deal furs, skins and other valuable bodily parts."} {What goes here to reset "skinvalue"?}

#STATE skinvalue 0

Another issue ive noticed, hyphenated strings seem to break the code and get rerouted to the main directory, eg: "a rune-etched golden sphere"

Hmm database variables are nice and all but im finding this is creating way to many variables for my taste, could anyone help me convert this trigger class into a normal database?

Create a database (Skins) with three fields (Name, Max, Min).
Check whether a record already exists.
If so, update the record.
If not, create a new record.

Something like this (untested):
