How would I make a black hole effect?

I have seen this question all over the place, and I've seen answers, but that doesn't work for me, I need a code that draws players into a part like a black hole would, I've tried

script.Parent.BodyForce.Force = Vector3.new(0, game.Workspace.Gravity, 0) * script.Parent:GetMass()

Which was on the ROBLOX Developer wiki, but that doesn't work. I've also seen people say "Use the Black Hole Bomb script" but that makes no sense to me (Honestly I'm really new to Roblox Lua) so an explanation, even if brief, would be appreciated,

Thanks.

If I were making a black hole this is what I do. The obvious solution is BodyPosition - but that won't create much of a black hole effect.

You can use some basic vector math to create a much more black-holeish effect with a BodyVelocity (or any number of other BodyMovers).

Solve for the directional vector between any two parts, take its unit, multiply by some amplification, and add it to the simulated gravity defection.

local ob_black_hole, ob_self = workspace.blackhole, workspace.inhole -- where ob_black_hole is the black hole, and ob_self is the part flying toward the black hole indefinitely

local force_amp = 1500 -- the vector amplification for our directional vector

game:GetService("RunService").Heartbeat:Connect(function()
	ob_self.BodyVelocity.Velocity = Vector3.new(0, workspace.Gravity * ob_self:GetMass(), 0) + (ob_black_hole.Position - ob_self.Position).unit * force_amp
end)

If you want a much more linear effect though, BodyPosition is definitely what I would go for.
