Hello Developers,
How I would able to create a basic plane system, I don’t need any fancy physics, just simple plane system using Roblox physics.
I am currently using BodyGyro and BodyVelocity however they are super unrealistic, they don’t feel like a plane, since they are so sensitive.
Feel free to reply any suggestion, code, idea on how I would able to make simple plane system.
There’s two sides to this. You can either go into fancy physics or go with BodyGyro and BodyVelocity. I’m afraid there’s not much of an in between that doesn’t involve aerodynamics and physics.
If you DO want to use BodyGyros and BodyVelocities. You can have the BodyVelocity on both wings and when you turn the plane, turn the BodyGyro and have the Wing thats the highest go forward and the other wing have No force or go Backwards. And the goal velocity should be the Planes lookvector
Edit: Also, what do you mean by “Too Instense”
My plane can just stay in air, even tho speed is 0. Also sorry for duplicated post, I didn’t post twice, it something up with forum
You need to set MaxForce to 0, 0, 0 since if you set Velocity to 0, 0, 0 it will just stay in the air
Because its trying to keep the Velocity 0, 0, 0
Well then show us the code. We can’t help you with that issue if we have no idea what the code is setting or doing.

Oh, uh, I don’t have the time to read through all of that. My apologies. What @LukaDev_0 said might fix the issue though.
Here is a quick view of the basics, rest of the code mostly just moves the constraints.
while wait() do
SteerCFrame = workspace.CurrentCamera.CFrame
if ThrottleIncrease then
if Throttle <= (Plane.Settings.MaxThrottle.Value - 1) then
Throttle = Throttle + 1
end
end
if ThrottleDecrease then
if Throttle >= 1 then
Throttle = Throttle - 1
end
end
Plane.Root.BodyGyro.CFrame = CFrame.new(SteerCFrame.Position, SteerCFrame.Position + SteerCFrame.LookVector * 20)
Plane.Root.BodyVelocity.Velocity = SteerCFrame.LookVector * Throttle
end
A classic (and relatively abrupt) way of solving this is having the velocity cut out when below a certain throttle. What I’d suggest is start scaling the maxforce of the velocity down once you reach this throttle threshold, to smooth it out.
if Throttle <= 50 then
Plane.Root.BodyVelocity.Velocity = Vector3.new(0, 0, 0)
Plane.Root.BodyVelocity.MaxForce = Vector3.new(0, 0, 0)
else
Plane.Root.BodyVelocity.Velocity = SteerCFrame.LookVector * Throttle
Plane.Root.BodyVelocity.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
end
You mean by that, like this?
