#MSS
|
After reading a bit about #MSS and %mss(), I created the following trigger:
| Code: |
#TR {({@list1})%s(%d)%s(%d)%s(%d)} {
#va inum {%ismember(%1,@list1)}
#if %ismember(%zonename,@list2)<1 {#additem list2 zonename}
#va znum {%ismember(%zonename,@list2)}
#mss {a1[@list1][@list2]=%2:a2[@list1][@list2]=%3:a3[@list1][@list2]=%4}
} |
I plan to use an alias later on to access the three VBScript arrays a1, a2, a3 using something like this:
| Code: |
#loop %numitems(@list1) {
#loop %numitems(@list2) {
#va l1 {%concat(@l1,", ",%mss(a1[%i][%%i])}
#va l2 {%concat(@l2,", ",%mss(a2[%i][%%i])}
#va l3 {%concat(@l3,", ",%mss(a3[%i][%%i])}
}
#echo @l1
#echo @l2
#echo @l3
} |
Of course, there will be more formatting and such to make it prettier, but this is the meat of it.
My questions about this are:
Are there any pitfalls with using #MSS or %mss in this way that I should be aware of?
Is this likely to consume exorbitant amounts of system resources?
Is it going to create a substantial performance drain?
Is there a slicker way to handle multi-dimensional arrays?
Or - if I click that little VBScript button in the trigger window, can I then combine zscript and VBScript together in the same code?
Thanks for your help! |

I wouldnt say this is slicker but if multi-dimensional arrays are what you want
you can do it in zmud.
| Code: |
#loop %numitems(@list1) {
#loop %numitems(@list2) {
#va l1 {%concat(@l1,", ",%item(%item(@a1,%i),%%i)}
#va l2 {%concat(@l2,", ",%item(%item(@a2,%i),%%i)}
#va l3 {%concat(@l3,", ",%item(%item(@a3,%i),%%i)}
}
#echo @l1
#echo @l2
#echo @l3
} |
That should do the same thing as your loop. |

I don't know about slicker, but it's certainly doable.
A multi-dimensional array in ZMud would look like this:
| Code: |
Variable
.line1 = item1|item2|item3|...|itemN
.line2 = item1|item2|item3|...|itemN
.line3 = item1|item2|item3|...|itemN
.lineN = item1|item2|item3|...|itemN
|
Because there's no sort of easy reference to each individual element, you probably want to maintain a few internal fields for easy validation and location:
| Code: |
Variable
.x = M
.y = N
.currentx
.currenty
.line1 = item1|item2|item3|...|itemN
.line2 = item1|item2|item3|...|itemN
.line3 = item1|item2|item3|...|itemN
.lineM = item1|item2|item3|...|itemN
|
Now you have the structure, but not necessarily the execution:
#FUNCTION Get {%if((%2 <= @%1.x) and (%3 <= @%1.y),%item(%db(@%1,line%2),%3),%null)}
%1 = variable name (do not include @)
%2 = X coordinate (item1, item2, item3, etc)
%3 = Y coordinate (line1, line2, line3, etc)
This function will return null if the specified location is out of bounds, or the element contents if inbounds
#FUNCTION Set {%if((%2 <= @%1.x) and (%3 <= @%1.y),%replaceitem("%4",%3,@%1.line%2),%null)}
%1 = variable name (do not include @)
%2 = X coordinate (item1, item2, item3, etc)
%3 = Y coordinate (line1, line2, line3, etc)
%4 = new contents
This function will replace the old element contents with the new contents, or return %null if the location was outside boundaries.
I'm not real familiar with functions, so I don't guarantee this will work as shown. |

So last night I found the pitfall, which is that values stored in VBScript variables do not appear to be retained across sessions. Looks like I'll
have to to use nested lists in zmud or a database in order to maintain this.
What I'm using this for is to maintain current pricing of commodities so that I can quickly see if there is an opportunity to buy for less than I can sell at elsewhere.
Thanks for your responses! =) |

By the by,
Zugg, if you see this, the only feature request I can think of today would be more seamless integration of VBscript and Zscript. What I mean, is maintaining state of script variables across logins and ability to use VBscript right in the middle of Zscript code without calling #MSS or %mss(). Hopefully that doesn't sound too stupid...  |

Some such things may become possible in the next version of zMud. I do not know what developments from eMobius and zApp will be brought into zMud, but the creation of zApp caused Zugg to become seriously involved in the low level guts of the MS scripting host system for a few weeks. I know he has achieved a nearly seamless integration between the script and component data sets and this may lead to a more seamless integration in zMud's future.
