BodyForce shockwave help

Hey Developers,

How do I make a sendback effect like from a certain point? Where depending on the players position relevant to a certain area, they get sent back reletive to that area. For an example of what I mean, use this image as a reference:

The green is where the player gets sent to if I tween it,
The Blue is the point at which the shockwave comes from,
and the red is where I want them to go,
and the pink is where the player starts.

Notice how the red goes away from the blue point no matter where they are? How can I acheive this effect where the player always gets sent away from the blue point?

Use BodyPosition to achieve this.

local BP = Instance.new("BodyPosition")
local Player = --Get the player in some way, I don't know how you want to do that
local Char = Player.Char
local HumRootPart = Char.HumanoidRootPart

BP.MaxForce = Vector3.new(4000, 4000, 4000) -- Will exert a force of 4000 on any axis.
BP.P = 1000 -- This is the power of the BP, this will measure the aggressiveness of the pushing (i.e. the speed)
BP.D = 500 -- This is dampening, basically kinda like a cushion effect to dampen the power.
BP.Position = (HumRootPart.CFrame * CFrame.new(0,0,10)).p -- This will set them 10 studs backwards from their current position, edit the '10' depending on how far back you want them to go
wait(5)
BP:Destroy() -- There are probably better ways to get rid of it properly

local BP = Instance.new("BodyPosition")
local Player = game.Players.LocalPlayer
local Char = Player.Character
local HumRootPart = Char:WaitForChild("HumanoidRootPart")

wait(4)

BP.MaxForce = Vector3.new(4000, 4000, 4000) -- Will exert a force of 4000 on any axis.
BP.P = 1000 -- This is the power of the BP, this will measure the aggressiveness of the pushing (i.e. the speed)
BP.D = 500 -- This is dampening, basically kinda like a cushion effect to dampen the power.
BP.Position = (HumRootPart.CFrame * CFrame.new(0,0,10)).p -- This will set them 10 studs backwards from their current position, edit the '10' depending on how far back you want them to go
wait(5)
BP:Destroy() -- There are probably better ways to get rid of it properly

Im using that but its not working. Whats wrong?

#4

game.Players.LocalPlayer can only be called from a local script. You will want this in a server script which will allow other players to see the player be flung back.

I suggest reading up on RemoteEvents, and creating a system that detects if the player is too close to that blue spot.

#5

Still not working!

Client Script:

wait(5)

game.ReplicatedStorage.RemoteEvent:FireServer(game.Players.LocalPlayer)

Server Script:

game.ReplicatedStorage.RemoteEvent.OnServerEvent:Connect(function(Plr)
	
	local BP = Instance.new("BodyPosition")
	local Player = Plr
	local Char = Player.Character
	local HumRootPart = Char:WaitForChild("HumanoidRootPart")

	BP.MaxForce = Vector3.new(4000, 4000, 4000) -- Will exert a force of 4000 on any axis.
	BP.P = 1000 -- This is the power of the BP, this will measure the aggressiveness of the pushing (i.e. the speed)
	BP.D = 500 -- This is dampening, basically kinda like a cushion effect to dampen the power.
	BP.Position = (HumRootPart.CFrame * CFrame.new(0,0,10)).p -- This will set them 10 studs backwards from their current position, edit the '10' depending on how far back you want them to go
	print("HAH")
	wait(5)
	BP:Destroy() -- There are probably better ways to get rid of it properly
	
end)

Are there any errors in the console?

#7

No errors in the console, so nope.

#8

Does it print what you told it to print?

#9

Yes.

I hate the character limit.

#10

Try this function

function pushChar(charToPush, pushPoint: Vector3)
	local HRP = charToPush.HumanoidRootPart
	local dir = ((HRP.Position - pushPoint) * Vector3.new(1, 0, 1)).unit --direction to push them in
	local pushForce = 100 --Force character is being pushed at
	local pushDuration = 0.2 --Amount of time the force is applied
	
	local BV = Instance.new("BodyVelocity")
	BV.MaxForce = Vector3.new(math.huge, 0, math.huge)
	BV.Velocity = dir * pushForce
	BV.Parent = HRP
	
	game:GetService("Debris"):AddItem(BV, pushDuration)
end
#11

Thanks, it works! However, how do I make the player also float upwards if the explosion point is below them?

#12 
function pushChar(charToPush, pushPoint: Vector3)
	local HRP = charToPush.HumanoidRootPart
	local dir = (HRP.Position - pushPoint).unit --direction to push them in
	local pushForce = 100 --Force character is being pushed at
	local pushDuration = 0.2 --Amount of time the force is applied
	
	local BV = Instance.new("BodyVelocity")
	BV.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
	BV.Velocity = dir * pushForce
	BV.Parent = HRP
	
	game:GetService("Debris"):AddItem(BV, pushDuration)
end
#13

Thanks! And now finally, how can I make the player slow down and eventually stop? (Without ending up falling down)

#14

Falling down like from a height or is your character tripping?

#15

Falling down from a height. I want it to explode out and then the player slows down and eventually stops without falling down

#16

I dont think I understand. You want them to be pushed into the air but not fall down?

#17

yes. They get pushed away from the shockwave, however eventually they slow down then stop. and they DONT fall back to the ground.

#18

Do you want to know how to get a force that is pointing away from a specific position like this?

#19

so you want them stay floating?

#20

Yes! kojo crashed already acheived this, however its not exactly how I want it (yet)
