The path of a Lua script to run to determine whether a record or pair of records should be included in the output from the ESP task.
Specify an absolute path or a path relative to the directory specified by LuaDirectory.
The script must define a function with the name pred
. The function must return either true
or false
.
The response to the result of the function depends on the type of ESP task.
ESP task | Result if the function returns true |
---|---|
And | The record pair is included in the engine output track. |
AndAny | The record in the Input0 track is included in the output. (Records from the other tracks are never included in the output). |
AndNot | The record in the Input0 track is discarded. (Records from the other tracks are never included in the output). |
AndNotThen | The record in the Input0 track is discarded. (Records from the other tracks are never included in the output). |
AndThen | The record pair is included in the engine output track. |
AndThenAny | The record in the Input0 track is included in the output. (Records from the other tracks are never included in the output). |
Combine | The record is combined with the record in the Input0 track, so that it is included in the result when the record from Input0 is output. |
