[Scripting Question] How to put bobbing effect smoother into pokemon icons?

[WolfPP]

Would anyone know how to make this "bobbing" effect smoother to pokemon icon, as we have in Pokemon PR?

Thank you!

Longer, more detailed animation, presumably.

Current bob in essentials is literally just cycling between a sprite and another one pixel higher/lower than it

I edited my game to 1 frame and edited the images of the icons for one frame as well.

For this reason I would like to know how to make a code to get this done. I think it's 'loop' or '.time', however I do not know how to do it.

Math.sin using the frame count as an argument?
that would get a nice wavy bob.
Not sure where to put it, since I don't have rmxp in front of me but it's a start.

Oh, do you have some tutorial than teach how to use 'Math.sin'?

Math.sin is just the trigonometric function sine. Like a sine wave. Here's a link to Wikipedia on sine waves. This one's a link to the actual trig function (also Wikipedia).
It's in radians. You can also use Math.cos. It's a wave like sin, but offset so at 0, you get +1 instead of 0.
Here's the RGSS docs page on the Math Module.

So I haven't gotten a chance to edit the scripts to make a ruby example for you. I do have some ugly Java code from a completely different project, drawing the pokemon icon at x=28 and y=32 + sin(framecount/2)

drawpanel.drawImage(activepkmn,28, 32+((int)Math.round(Math.sin(frameTime/2.0))));

But like play with the numbers in a graphing calculator or something. I ever really bothered to make the bounce very fancy.
