Make hot air balloon circle map in a loop seamlessly (looks like it's flying)

I have tried some code previously, but then deleted it so I need help restarting.

I assume, using the TweenService is the best option, and I want this model:

to fly in a loop around the map changing altitude, by bobbing up and down regularly, but seamlessly while it is still circling the map.

Please can somebody assist me!

Thanks for your time in advance.

You could probably use a local script that on every frame (Or a server script on Stepped event), sets the balloon’s Y position to some value + the sine of os.clock() multiplied by a speed and then multiplying that result for the variance in height. Here’s how the movement would look:

There’s probably a better way, such as animating it, but this is what i can provide

since it doesn’t seem to be important to the gameplay, I guess you could just define a table of positions that the baloon can follow and tween it all on the client
Loop through the table → get the position → tween to that position → the tween’s .Completed signal fires → go to next position etc…

That’s a lot of coding giberish that idk. :sob:

Can you give an example please?

Can you give an example please.

Relatively new to scripting, think I understand what you’re saying, but wanna be safe 4 sure. :smiley:

Sure

local speed = 0.05
local heightDiff = 5

local blimp: Part = workspace.Blimp
-- you can change this ^ to the blimp's root part (where everything is connected to)

game["Run Service"].RenderStepped:Connect(function()
	blimp.Position = Vector3.new(
		blimp.Position.X,
		100 + heightDiff*math.sin(os.clock()*speed),
		blimp.Position.Z
	)
end)

And I put this script in the blimp model?

Into StarterPlayer → StarterPlayerScripts
Also you have to change the blimp variable to be the blimp’s root part

I saw that, thank you I’ll take a look.

Not sure if it’s even moving. :sweat_smile:

Hmm, i think the speed variable is too low

Mhm thanks. Can you make it go around the map in a circle? Like in a loop while doing that.

Oh yeah definitely!

local speed = 0.3
local heightDiff = 3

local movespeed = 0.05
-- speed at which the blimp moves around the map

local radius = 200
--distance from center of map

local blimp: Part = workspace.Blimp
-- you can change this ^ to the blimp's root part (where everything is connected to)

game["Run Service"].RenderStepped:Connect(function()
	blimp:PivotTo(CFrame.new(
		
		math.sin(os.clock()*movespeed)*radius,
		100 + heightDiff*math.sin(os.clock()*speed),
		math.cos(os.clock()*movespeed)*radius

		) * CFrame.Angles(0,math.pi/2 + (os.clock()*movespeed),0)
	)
end)

@RobotThom1 had a great solution but make sure to account for the player frame rate so everything is synced up and matching the speed you want it to be at. You can achieve this by including deltaTime.

local speed = 0.3
local heightDiff = 3
local movespeed = 0.05 
local radius = 200
local blimp = workspace.Blimp
local timeElapsed = 0

game["Run Service"].RenderStepped:Connect(function(deltaTime)
	timeElapsed = timeElapsed + deltaTime

	local x = math.sin(timeElapsed * movespeed) * radius
	local y = 100 + heightDiff * math.sin(timeElapsed * speed)
	local z = math.cos(timeElapsed * movespeed) * radius
	local rotation = timeElapsed * movespeed

	blimp:PivotTo(CFrame.new(x, y, z) * CFrame.Angles(0, math.pi/2 + rotation, 0))
end)
