[reloaded] I am struggling with RoundLine

[Mor3bane]

Hi all,

The goal: Make a RoundLine Hour circle that starts at a variable time and concludes at another variable time.

What I think I need to do: Make a RoundLine Meter that has a "zero" position and it draws in an arc until the "end" position reletive to an actual clock's hours.

How to do it?: I can draw a circle, size it, position it, but not much after that.

I cannot seem to get my head around all of the different parameters - without a basic working meter to start from - basic would be managing the start and end positions effectively/accurately.

I will keep tacking away, and hopefully someone might be able to get me rolling in the right direction in the mean time.

Perhaps some thing like this can help you: https://forum.rainmeter.net/viewtopic.php?p=122296#p122296

Thanks @ FreeRaider

I'll check it out. Looks to be fairly close to what I'm going for.

So, I made some "progress".

However, I am having trouble achieving my actual goal :-
To get the roundline "sundial" to begin and end at the correct 24 hour clock positions for sunup and sundown.

Here's what I have managed so far;

I modified these and without knowing in advance "exactly" if this is working so far, here are the edits:-

Seems ok but on a 24 hour increment the change will not be immediately apparent - to me at least.

The ideal outcome would be for the MeterSunUp and MeterSunDown to be a complete single arc, however this looks like it progresses until the MeterSunDown reaches it's 100% value of the actual sunset time.(?)

Out of curiosity, do you want something like this one ?

Out of curiosity, do you want something like this one ?

That is what I am modifying - I am adding a "sundial" to it - or trying to anyway.

[eclectic-tech]

So, if I understand, you want a 2 pixel wide, 20 pixel diameter radius circle, that shows when the sun is up/down in relation to your 24 Clock, which has midnight at the bottom center?

First you need to set the startangle at the offset to your 'zero' position (bottom center to match your 24 hour clock), so that would be (Rad(90)). Then add to that, the time of sunrise using the value of the sunrise hour times 15 (each hour of a 24 hour clock is 15 degrees) + the sunrise minutes times 0.25 (each minute is 1/4 of a degree) to set the starting point at sunrise.

Then in your measure to drive the roundline, use the difference between sunset hours times 60 plus the sunset minutes and the sunrise hours times 60 + the sunrise minutes, and divided that by the total minutes in a day (1440) to get a percentage.

You do not need to calculate the sundown, since it is the remaining percentage value of sunup.

So to display, use a roundline, solid filled circle, the same size as the sunup meter to start (this will represent the sun down time) and overlay the sunup roundline.

I used a 10 pixel wide arc to show the settings...

This will match the times on your 24 hour clock.

If you had something else in mind, let us know...

[Mor3bane]

eclectic-tech - thanks a ton

Now that I see the math, it makes all the sense in the world

Never was too slick in maths.

I was actually aiming at a 12 oclock at the top dial so as to appear more natural

However, the sundial idea kind of grew in different ways - to possibly function like one rather than using the name

Anyway, here is the end product -


So it is obvious that I was modifying someone's work, but you can see what I meant by "functioning like a sundial" by having the shadow be relative to the position of the sun in the meter - but I am contented with the result as I originally imagined it.

Thanks again eclectic-tech

[eclectic-tech]

Glad to help.

To have midnight at the top center, replace '90' in the StartAngle value calculation with '270'. The default starting point (Rad(0)) is at the 3 o'clock position, so just add (or subtract) the degrees to start where you want.

Nice edit on the skins!
