I am doing the slideshow and I need to fill of polygon object gradually changed color in a random sequence. I write function that changes color at once, but I can not do so in the form of animation.

Maybe already have a ready solution?

If you do by method action/trigger, the color is changing rapidly. Need to the color of fill changed smoothly.

If you're looking to create a smooth transition between colour changes then you could use two polygons and fade in & out changing the colours.

Or if your looking to script this, then use transparency to create the fade effect:

1.Set colour
2. Use for loop with delay to increase the transparency to about 80%
3.Set new colour still at 80%
4. Use for Loop with delay and reduce the transparency back to 0%

Several ideas... no single solution.

First, look up SetBtnColour (??) or similar commands related to Get/SetBackground. Works on Button objects and may offer a few more options than ordinary objects.

Mostly I am thinking in terms of OpusScript... more 'Advanced' than basic if you don't mind. You can find the equivalent action or animation without scripting.

If you use 2 objects, you can "Fade" one out and "Fade" the other in. Similar you can use the SetTransparency command and specify a time.... one object to 100% and the other to 0%. [Edit: change Colour of one when it is fully 'faded' or completely 'transparent'.]

Another way... 2 objects again. Show and Hide in pairs. Use "transitions"... e.g., 'dissolve', pixel effects, ... whatever. Again you have 'time' parameters. Don't overlook this possibility.

If you want to get 'crazy', maybe "Blend" (as in the Effects Tab) can be applied in similar gradual fashion -- I don't know.

Lastly, you can set up a loop... in a way to take a couple seconds. During that time, you can run a variable (number) up or down some range ~60 for a start. Now if you do that for 1 to 3 vars... you have R, G, B moving some range. You would be "setting the colour" with each pass thru the loop.

Thanks Mack, but you have changed the transparency of the whole object, but I need only fill.

Thanks Lar_123, you give me a lot of interesting options that I necessarily useful in creating screensaver.

I have done so: three variables (r, g, b) to randomly change their values to r=r+1 or g=g-1 etc into the loop with delay. It is very nice effect.

Created the screensaver. Looks excellent. In a opus pub preview - everything works, although the CPU up to 50%.
But start of the final screensaver publication cause windows`s crash.
Tried to remove my colour animation - does not help.
Screensaver have 4 pages, 12 vector objects of all (30...100 kB each), several complex animations from these objects.

Do not make a beautiful screensavers in Opus?

I found the cause of the collapse of the system - setting the pages "Go this page when finished" - <random>.
Unfortunately, I can not take this good opportunity.

Using vectors with changing RGB values, transparency, and animations is going to use too many resources. If the vector animation is using all your computers resources, then the call to a random page will send the pub to a page that doesn't exist and crash. Been there, done that.
I don't make screensavers that use more than 15% CPU.
