#FUNC and #LOOPDB question
|
I have a couple of questions...
1) Is there a built-in index you can use, when using #LOOPDB ? Or do I have to make a dummy variable where i add 1 each time it loops in the DB ?
2) Is there any way to prevent Zmud from writing out a functions code eg.
I have this function:
#FUNC test {#IF (%1 > 1) {#show Yes} {#show No}}
If I call it using @test(5) it will output the entire function if-sentence,
to the mud.
I just want to get the result printet on the screen ("Yes" in this case).
Is this possible or have I misunderstood something? |

1) I thought you might be able to use %i, but looks like you can't, so I'm leaning towards no built-in index variable...
2) You can't use commands in functions. Try this:
| Code: |
| #FUNC test {%if(%1 > 1,"Yes","No")} |
Then to display the result, you would use #SHOW @test(5). |

As far as 1, no you can't get an iteration count from #LOOPDB, however as the help file states it does have built in index variables of %key and %val to track those.
| Code: |
LOOPDB
Syntax: #LOOPDB database-rec {commands}
Loops through each key-value pair in the database variable and executes the specified commands. When executing the commands, the variable %key contains the current key and %val contains the current value of the keyword.
LOOPDB Example
#ADDKEY db Name Zugg
#ADDKEY db Race Dwarf
#LOOPDB @db {#SHOW %key "=" %val}
Loops through the database record db and displays the key value pairs. In this example, the result would look like:
Name = Zugg
Race = Dwarf

If you use commands in a function, you have to wrap them in a function like %exec() that can handle commands inside them.
