The problem
Currently, creating a looping "counter" in Rainmeter is done with a Calc measure and a modulo mathematical function:
Code: Select all
[MeasureName]
Measure=Calc
Formula=(MeasureName % 100) + 1
1) The "starting" value of the counter can't easily be "0", or really any number other than "1".
2) It is difficult to increment by other than "1", as that impacts the starting value as well.
3) It is difficult to count "backwards".
4) You must manually set MinValue and MaxValue to use as a percentage.
5) This can only create an "endless" loop, you can't loop 3 times and stop for instance.
6) Overall, the function is not very intuitive to new or non-programmer Rainmeter users.
The solution
The new Loop measure can be used in place of this modulo approach. The way it works is:
The measure will be the value of StartValue for one update, will increment based on the value of Increment on each subsequent update, and will be the value of EndValue for one update. If LoopCount is other than 1, the loop will then repeat.
A couple of simple examples might be:
Code: Select all
[MeasureLoop]
Measure=Loop
StartValue=0
EndValue=50
Increment=1
LoopCount=0
Code: Select all
[MeasureLoop]
Measure=Loop
StartValue=100
EndValue=0
Increment=-10
LoopCount=1
Additional features
If you set InvertMeasure=1 on the measure, the value that is returned is the "opposite" of the measured value. This has the effect of "counting backwards", with no other change to the measure options required.
The measure can be reset and will start over with all current option values when the !CommandMesasure MeasureName "Reset" bang is sent to the measure.
Some rules
There are some rules for how this measure works that should be kept in mind:
1) All options must be positive or negative whole numbers, or formulas that resolve to whole numbers. Fractional values will be truncated.
2) The measure will have a range that is the difference between StartValue and EndValue for use by meters requiring a percentage. There cannot be a negative percentage, so the range will always be lowest value to highest value. MinValue will be set to the lower of StartValue / EndValue, and MaxValue will be set to the higher of StartValue / EndValue.
3) Any dynamic change to any of the four measure options, or dynamically changing InvertMeasure on the measure, will cause the loop to be reset and start over with the new values.
