How do I make a smooth floating/wondering motion

I want to move a sprite, as if it's gently floating in the water or in space. (within about 10 pixels of its original position)

Similar to this video, only more smooth, without sharp changes of direction:

Can't figure out how to do this.. So far I had the best result with a combination of two LiteTweens, but it still doesn't look as fluid and natural as I want.

Just need a sprite and a few variables. No tweening etc

Heres the code so you can see:

Oh ok, in the video linked they behave more like my ones.

And you said you only wanted them to move to within about 10 pixels of their starting location...

Yeah, sorry, couldn't find the right video.

Well, maybe a bit more than 10 pixels. The important part is that the motion should be pleasant and relaxing.

I've done similar movement for a background butterfly sprite in my game using the 2 Sine behaviours, one vertical and one horizontal, with random period and magnitude.

That might give you something close to what you want.

Thanks! I think I tried Sine, but it looked kind of repetitive.. Do you change random values after every cycle?

Do you change random values after every cycle?

There's no need for that. Sine automatically does random if you set the Period Random, Period Offset Random and Magnitude Random values in it's properties.

Here's an example with bubbles

Hey dop2000,

I played around a bit and found out that Custom Movement could be a good option.

It offers several settings on different ways.

Sorry if I'm a bit late to the party. I did something similar for my own project so sharing my solution as well, in case anyone finds it useful.

I’d also recommend using the sine behavior. Maybe assign multiple sine behaviors, then, instead of setting the behaviors random property, just script a system condition to change the magnitude and speed every X seconds, for random(x,x) magnitude and random(x,x) speed.

tunepunk , Nice, although the sprites are wondering away, not around their original position.

Nexis717, Yep, that's what I decided to do after all. Sine still makes the sprite move in ellipses (see the second image in my previous comment), but it requires less code and looks good enough for my task.

dop2000 nice. I can understand it’s not perfect but, maybe fooling around with sine and custom movement (simulate controls) could give it a bit of a “random movement” effect. Let us know if you come close to perfection
