Hello fellow devs. I've run into something. I wrote this script which handles moving of part perfectly like , but I don't take turning into account.

Here I added another Table to hold nulls, that I call values which should be applied when helicopter is stopped(or no key is pressed, to be precise). The problem I have to solve, is that I should rotate Gyro based on lookVector and constantly update it, but I have trouble figuring out how to do it with this code. I came up with this solution

01function Cframe(x, z) 
02 
03    if x or z then
04 
05        return CFrame.Angles(x, 0, z)
06    else
07        return CFrame.Angles(0, 0, 0)
08    end
09 
10end

this is the function I made which would replace cframe.Angles in tables.

02                  [tostring(enum.T)] = {Cframe, Vector3.new(0,(m*g)/27, 0)},

The problem with this is, that if I release W key or S Key, in Nulls Table first element is just CFrame.new() so passing arguments like that is not possible.

Maybe there's some methods I don't know(which there clearly are), or I'm missing something obvious. Note:I use T, R, Y, G, H, F and J keys in tables, because they are not available in studio Run test mode.

Can I please have a nice detailed view of the "Heli" part in explorer tab? Make sure to open all the folders, so I can see what is where. Arj783 72 — 5y

Idk what kind of math you have going on right now but all you have to do is use a body position and reference the main part's positing.X + a few studs and just make it move like that namespace25 594 — 5y

This would be a lot easier if you used modern body movers and not legacy Sir_Ragealot 72 — 4y
