Fan spins with whole car

[dullanthony12345]

1. What do you want to achieve?
   i want to have a meshpart fan spinning in an A-Chassis car like radiator fans.

2. What is the issue?
   the fan script im using is causing issues, it like spins the whole car. i want it to spin and at the same time being able to drive the car normally.

3. What solutions have you tried so far?
   i tried disabling collisions, i tried putting the fan in misc instead of body.

heres the script

here is a video of the issue. the car goes crazy.

any help at all is appreciated.

or if anyone can make a working on for me and give it to me that would be awesome, i have the model here: test - Roblox

use a rigid constraint to connect the fan to the car , cframe the attachment to rotate. I had this same problem with my mortar. The mortar makes the whole ship rotate. I used a rigid constraint and the issue was solved

[dullanthony12345]

do i just add a rigid constraint to the meshpart? i know nothing about scripting or rigid constraints or attachments.

[ryanadamdragon (Dragon)]

yes use attachments, the attachments should be at the positions of where you want your fan to be

if there are other things interfering it wont work, make sure nothing is welding your fan to the car

like this?

Rigid constraint not weld constraint.

[dullanthony12345]

i got it like this now but the car still glitches out

[ryanadamdragon (Dragon)]

make sure both attachments are together and are at the position you want the fans to be

[ryanadamdragon (Dragon)]

make the fans massless and cancollide off

[dullanthony12345]

still wont work

use Weld and its C0 property

while true do task.wait() -- or [[ RunService.Heartbeat:Wait() ]]
    Weld.C0 = Weld.C0 * CFrame.Angles(0, math.rad(Angle), 0)
end

[dullanthony12345]

like this?

[V_ladzec (Volter)]

yep but you forgot Weld variable

local Weld = scipt.Parent:WaitForChild("Weld")

[dullanthony12345]

like this?

[V_ladzec (Volter)]

put it before while loop

local Weld = scipt.Parent:WaitForChild("Weld")
while true do task.wait()
    Weld.C0 = Weld.C0 * CFrame.Angles(0, math.rad(Angle), 0)
end

[dullanthony12345]

this?

[V_ladzec (Volter)]

also put Angle variable you can change its value if you need

local Angle = 2
local Weld = scipt.Parent:WaitForChild("Weld")
while true do task.wait()
    Weld.C0 = Weld.C0 * CFrame.Angles(0, math.rad(Angle), 0)
end

[dullanthony12345]

may i just send you the model? i can send it

[V_ladzec (Volter)]

make sure Part0 is car and Part1 is fan and just paste code above
