updating locations on the map
|
An image of Zeke at &myloc appears before you.
-----------------------------------------------------------------------------
#VAR mylocnum %mapquery("[Name] LIKE '%@myloc%'")
#te @mylocnum
This doesn't work. Looks like the value of @myloc isn't being passed inside the %mapquery fucnction.
I just want the mapper to update my location upon the trigger text.
Also I would like to plot my enemies location on the map using the same method, thus giving me a path to them.
If there is a way to make something like this work, gimme a hint will ya?
Thanks. |

That's because the @myloc is within the quotation marks, which makes it a literal string rather than a variable name to be expanded. Try this:
| Code: |
#VAR mylocnum %mapquery(%concat("[Name] LIKE '%", @myloc, "%'"))
|

For the second part, you could do something like:
| Code: |
| #pathhigh %pathfrom(,@mylocnum) |
But to make either of these things work, you also have to be sure that @mylocnum is a single number, in other words, that the %mapquery returns only a single number, not a list of room numbers. |

I ought to mention something else, to whet your appetite for the new version of Cmud. Version 3.xx, currently in beta testing, includes a major rewrite of the mapping system. One of the new features is the ability to mark and keep track of multiple locations. You normally have one location for yourself, but you could add other locations for other people, pets, or whatever. They would be marked on the map the same way your own location is marked, but you could specify a different color for each. You can dynamically change which location object gets tracked (moved with movement commands), though that's not necessary for your current needs. Something to look forward to!

Thanks Rahab!
That did the trick, and those new mapper options might be worth looking into. |

I was reading some old stuff the other day and came upon this gem.

And then I switched all my mapquery stuff to, for example,
| Code: |
| #VAR mylocnum %mapquery({[Name] LIKE '%@myloc%'}) |
which sure looks a lot prettier. |
