How can I add on to this CFrame script?

Down below I have a working script:

Now I have a question about so script…
– If I want to achieve a moon orbiting around a planet that is orbiting, how would I do this. I assume I need to somehow get the CFrame of the planet and make that the orgin?

If anyone needs further explanation please let me know!

u have to use trigonometry for it, mainly sin and cos. u first have to convert degrees to radians. then use sin and cos for x and y axis e.g

local radius = 5 --offset

local formula = math.rad(degree)
local x = math.sin(formula)*radius
local z = math.cos(formula)*radius

Part:PivotTo(Origin * CFrame.new(x, 0, z))

So where in the code should I use this, if you don’t mind me asking?

XxgamesxX904 · September 4, 2023, 4:08am

or do I need to put this script in the moon object?

ur code for achieving this would probably be

local alpha = 0
local radius = 5 --offset
local Origin = CFrame.new()

local Part = workspace.Planets.Mercury

while true do
	alpha += .5
	local formula = math.rad(alpha)
	local x = math.sin(formula)*radius
	local z = math.cos(formula)*radius

	Part:PivotTo(Origin * CFrame.new(x, 0, z))
end

Alright, I’ll attempt this. I’ll let you know the results.

David:

local alpha = 0
local radius = 5 --offset
local Origin = CFrame.new()

local Part = workspace.Planets.Mercury

while true do
	alpha += .5
	local formula = math.rad(alpha)
	local x = math.sin(formula)*radius
	local z = math.cos(formula)*radius

	Part:PivotTo(Origin * CFrame.new(x, 0, z))
end

Here, I apologize for not elaborating further. Here’s and image describing what I am trying to accomplish. The Bigger Object will go by Mercury while the smaller will go by Moon.

The white line depicts the planetary orbits.

consider Bigger object the Part and Mercury origin and the smaller as Part and Moon origin

XxgamesxX904 · September 4, 2023, 4:25am

So how should I write the code for this, would I put a script inside the moon object?

aliaun125 · September 4, 2023, 4:27am

u have to adjust the code accordingly to ur workspace hierarchy. U can just put the script in serverscriptservice and reference all the objects from there

alright, will do! Thank you for the help

Question, I’m still having a little trouble with this. Would you be able to contact me on discord for easier communication? If you’re not comfortable with this, that’s completely okay!
