Is it possible to make a code bit such as this?

The easiest way to achieve that effect is to put your 'do something' script into the room script for room 667 in the mapper, rather than using a trigger.

To do so, put the map in Map Mode (and make sure it's unlocked), then right-click on the room and choose 'Properties'. In the resulting dialog, there should be a pane below the room description with tabs for 'Notes', 'Room Script', and 'Walk Script'. Click on 'Room Script' and type in your 'do something' commands. Those commands will be invoked whenever the mapper detects you entering that room.

Thats a good idea, but I'd like to have the ability to disable this function once its done. A trigger of some sort would do exactly that.

Here you go Prog. I tested it before posting in the sample session.

So wrap the room script commands in an #if statement, and use a variable to enable/disable the code. E.g. '#if (@room667CmdsEnabled) {do something}', and you can set room667CmdsEnabled to true or false to turn the code on and off.

The description of the expression trigger from the KB is "The Pattern field is an Expression. When this Expression evaluates to True, then the trigger fires. The trigger is only tested when variables used in the expression change their values." My suspicion (on the basis of no investigation whatsoever) is that expression triggers do NOT fire when predefined variables (%something) change - only when regular user-defined variables (@something) change.

Weird, it isn't working for me. I pasted your exact trigger as well, checked if the map pointer is on correct Roomkey and nothing, not a beep.

If its any significance, Perl regex bit on Trigger's Test Tab is giving it as ((oomkey==5)) instead. Kind of strange.

Thanks for all the help so far, too.

EDIT: Hrm. In a nutshell I was just now sending a command into MUD for a gathering certain data and the Expression Trigger suddenly hit and gave the succession message. But nothing happend when I was just sitting around, doing nothing other than randomly pressing Enter at times :/

Look at the edit to my above post. Note that it fires when @Okexit==1, and NOT when @Okexit==0.
But it does need @Okexit to have changed from 0 to 1.

Great! Additional variable did the trick. Basically what I need to do now is switch this Variable true when I have to use the Trigger and then turn it false once its done. Seems that there really isn't any need to turn Trigger itself off.

Thanks for all the help Arminas and JQ. I feel tidbit smarter yet again!

I ended up using Pattern Trigger to grab the Room Name saved inside a Variable and made this Trigger to set KeyRoom Variable to 1.

Then the Expression trigger activated when KeyRoom wasn't null and everything was ok.

Basically this was needed to prevent wrong data received/sent when Char's location wasn't the same as the pointer on Map.

That being said, started to think about a feature (obviously would be a CMud deal which I don't use myself yet) which would check if Char's actual location and Map's Pointer location are the same. When they are, it would give 1, if not 0.

If such function already exists, please point me towards it! If not, maybe something cool to add for CMud if its even possible.

Thanks,

Prog
