shapes and average

No, I have a feeling that I am still a noob in Rainmeter world.
I am always stumbling on RegExp, IfCondition, Substitute, !EnableMeasure...every day, every time I write/modify Rainmeter code.
"Why, why doesn't this code work?!"
"Where does this error come from?"
"I can't figure out!!"

I suppose everyone of us is experimenting such feelings sometimes, but I definitely doesn1t consider you being a noob. Just keep working...

TransformationMatrix is the devil's work...

No, it's not at all. It's pure mathematics. And math is my (our?) friend.

I for one, welcome our transformationmatrix overlord.

but a little bit later I'll post an example you to see what am I talking about.
Stay tuned, if interested...

And here is the promised example. The following skin has an initially not rotated yellow rectangle. You can set the coordinates of the center of rotation, through the CenterX and CenterY variables. Take care these coordinates are relative to the position of the [MeterTransformationMatrix] meter. For instance for CenterX=0 and CenterY=0 you'll get the meter rotated around its upper left corner.
You also have to set the rotation angle. Note that a positive angle means anticlockwise rotation, while a negative angle means clockwise rotation.
If you click the yellow rectangle, you get it rotated.
The code:

Code: Select all

DynamicVariables=1
LeftMouseUpAction=[!SetVariable Rotate "(1-#Rotate#)"][!UpdateMeter "#CURRENTSECTION#"][!Redraw]

Don't be afraid of the above code, it's not so complicated as it seems at a first look. Feel free to ask if you can't figure out something related to the code.

[balala]

Do you find it complicated? Because it's not too much...

[ItsJustRyan]

Its working perfectly

[balala]

Its working perfectly

I'm glad.
