Learn how to use sin and cos waves. I use unity here but, but the math is agnostic
Sine and Cosine are fundamental to game development. Once you understand how Mathf.Sin and Mathf.Cos work, you'll find yourself reaching for them all the time. You can create circles and waves, make things hover, create orbits, add enemy behavior, etc.
I used 'Shapes' to make a few of these effects, you can check it out here: https://assetstore.unity.com/packages/tools/particles-effects/shapes-173167?aid=1011lkRxs

sine and cosine are trigonometry functions which return oscillating values between 1 and negative 1. by feeding the function a climbing value like time and setting our bowl's y position to the result it will smoothly travel between the sine range if we add an offset to our time input we can begin to observe the benefits sine provides cosine yields similar results to sine but leads by 90 degrees where the hell do these degrees come into it you may ask well let me explain how these values are generated meet the unit circle it's just a circle with a radius of one let's say we input 225 degrees into both our sine and cosine functions take note these functions actually take radians as input so we have to do a quick conversion as you can see by combining both the sine and cosine we can plot a point on the circumference of a circle now if we once again use time as an input value it becomes quite apparent how these beautiful waves are generated also take note of how the cosine wave is offset by 90 degrees it's worth mentioning you can alter the speed of the wave by simply multiplying the input value you can also change the amplitude by multiplying the result of the function all right so what can you do with them well you can obviously make waves in circles but here are a few additional examples [Music] if you want to see more visualizations in the future subscribe also consider becoming a tarot bro on my patreon link in the description alright see you next time [Music] you
