I'd like to draw the trajectory of an object that is moving circularly, but I do not know how to do it. Could you tell me a good way?
I've not done a orbiting around something, but I am using Cos and Sin to generate static items around the object. If you use TrailRenderer with the use of MathF cos and sin to rotate around an object.
var y = amplitude * MathF.cos(Time.timeSinceLevelLoaded * speed) + currentPosY
var x = amplitude * MathF.sin(Time.timeSinceLevelLoaded * speed) + currentPosX
I've not watched it, but "Board to bits" on youtube has a tutorial on the matter. of space orbiting for a planet playlist.
Hope this is the right direction for you.
