How do I get this beam to have some sort of physics when I attach to it

So I have created a beam from my players position to a fixed point, but the problem is the beam doesnt really have any sort of physics and I’m looking to make something like the bloxverse web swinging.

You could try applying a velocity based on the distance of the beam and direction of the beam relative to the character

#3

How would I do this in actual code, could you explain?

#4

I’ll do an example in studio and show you.

Oh thank you I really appreciate it man Ill wait here patiently

As @cjjdawg this can be achieved with BodyMovers. I created a quick proof of concept using BodyPosition instead of BodyVelocity, because I think it might be better for this task.

Without fine tuning the forces, this is the result

Code I used (LocalScript in StarterCharacterScripts - BodyMovers are replicated to the server automatically, so you don’t need to worry about that)

local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Mouse = Player:GetMouse()
local BodyPosition

Mouse.Button1Down:Connect(function()
	BodyPosition = Instance.new('BodyPosition')
	BodyPosition.Position = Mouse.Hit.p -- endpoint of your beam
	BodyPosition.Parent = Character.HumanoidRootPart
end)

Mouse.Button1Up:Connect(function()
	BodyPosition:Destroy()
end)

BodyPosition has some properties that you can mess around with, P and D. These aren’t explained super well in the wiki, so it may be hard to get the proper result, but in general its better to have a rather high P (power) and rather low D (dampening).

@PlayingRobIoxStudio Do you still me to do it? I was going to do something similar to this.

yes id love to still see your way please

#9

thank you mayor ill keep this is mind

#10

So Ive tried this method you showed and it seems the force isnt strong enough to bring the player to the end of the beam

#11

That’s because I didn’t change any of the BodyPosition’s properties.

That said, I’ve actually been having a bit of fun with this myself because I’m bored and I’ve actually been working on this just for the fun of it.

I’ve changed the P and D values to make the swinging seem a bit better, so

Mouse.Button1Down:Connect(function()
	BodyPosition = Instance.new('BodyPosition')
	BodyPosition.Position = Mouse.Hit.p -- endpoint of your beam
	BodyPosition.P = 10e20
	BodyPosition.D = 750
	BodyPosition.Parent = Character.HumanoidRootPart
end)

If this still isn’t how you want it to react, can always change P and D. Remember, P should be high while D should be low.

#13

Yeah I used those same exact properties and this is the result Im getting

#14

What is a vector force exactly?

#15

I’m working with just the default character and physics, so I think it might be a problem with your falling script. It looks like its conserving momentum and moving forward, so maybe however you’re doing that is messing with the BodyPosition.

#16

Wait i made some mistakes in the code fixing in studio

#17

My gravity is pretty high so I dont know if that might be the problem.

Yeah, that’s definitely it. BodyMovers are really just applying a force, which is a function of Mass * Acceleration. A greater gravity means a greater downward acceleration for the BodyPosition to overcome.

I multiplied to BodyPosition properties by workspace.Gravity/196.2 (default gravity = 196.2), and the behavior is more or less the same in a higher gravity.

Mouse.Button1Down:Connect(function()
	BodyPosition = Instance.new('BodyPosition')
	BodyPosition.Position = Mouse.Hit.p -- endpoint of your beam
	BodyPosition.MaxForce = BodyPosition.MaxForce * (workspace.Gravity/196.2)
	BodyPosition.P = 10e20 * (workspace.Gravity/196.2)
	BodyPosition.D = 750 * (workspace.Gravity/196.2)
	BodyPosition.Parent = Character.HumanoidRootPart
end)

Uhh, its very buggy now and shoots me right through the baseplate

#20

Uh, that still looks like a problem with the falling script. Try without animation or anything, and see how it works.

Working with physics absolutely sucks and is really just a matter of trial and error until you find the right numbers to do stuff.

#21

Hm, Im pretty sure it has nothing to do with the animation, I’m certain of this well I guess Ill have to trial and error, thanks for the help both of you
