How to make a part move away from another part facing a certain direction?

You can write your topic however you want, but you need to answer these questions:

Hello, I am wondering how I can make a part move away from another part based on the way the parent is facing.

  1. What is the issue? Include screenshots / videos if possible!

My issue is that my test script is not working. I think I am doing velocity wrong.

wait(2)

local PART = script.Parent.Parent
local brick = script.Parent

brick.Position = PART.Position
brick.Anchored = false
brick.Veloctiy = Vector3.new(0, PART.CFrame.lookVector * (50), 0) --???
  1. What solutions have you tried so far? Did you look for solutions on the Developer Hub?

I have tried messing around with CFrame, asking friends, looking at other threads, etc but I can’t seem to get the last line to work. I have another solution to making this work but I want the part to move away from the parent based on where the part is facing. Not in any direction like so:

brick.Velocity = Vector3.new(math.random(-20,20), math.random(80,110), math.random(-80,-50))

Could I possibly get some help to clarify my problem?

well the current problem with your script would be Part.Cframe.LookVector * 50 as that would be a Vector3 I believe

now one solution to your problem would be

wait(2)

local part = script.Parent
local brick = script.Parent.Parent



-- this will be used to make sure your facing the part you want to avoid
local g = Instance.new("BodyGyro")
g.CFrame = CFrame.new(part.Position,brick.position)
g.MaxTorque = Vector3.new(500000000,500000000,500000000)
g.Parent = part

local speed = 50

wait(2)

---- body gyro I only call here in case the "brick" part moved.
g.CFrame = CFrame.new(part.Position,brick.Position)


part.Velocity = (part.CFrame + part.CFrame.LookVector * -speed).Position <-- this will make it go backward

edit actually what i just did with velocity would be used for bodyposition which would make it

wait(2)

local part = script.Parent
local brick = script.Parent.Parent



-- this will be used to make sure your facing the part you want to avoid
local g = Instance.new("BodyGyro")
g.CFrame = CFrame.new(part.Position,brick.position)
g.MaxTorque = Vector3.new(500000000,500000000,500000000)
g.Parent = part
local b = Instance.new("BodyPosition")
b.Position = part.Position
b.MaxForce = Vector3.new(500000000,500000000,500000000)
b.Parent = part
local speed = 50

wait(2)

---- body gyro I only call here in case the "brick" part moved.
g.CFrame = CFrame.new(part.Position,brick.Position)


b.Position = (part.CFrame + part.CFrame.LookVector * -speed).Position <-- this will make it go backward

if you wanted to use velocity i belive you would just

part.Velocity = part.CFrame.LookVector * -speed

along with orienting your self toward “brick”

#4

The original line was:

.Velocity = Vector3.new(math.random(-20,20), math.random(80,110), math.random(-80,-50))

This works well:

part.Velocity = part.CFrame.LookVector * -speed

but I can only seem to get it to move if I put it in a loop. While in the original line, it is just ‘thrown’ away from the part so it is seemingly flying through the air by itself without the need of a loop or anything to keep it moving. Is it possible to do the same thing without the use of bodyMovers and loops?

#5

there has to be some kind of way to where I can just do:

Vector3.new(math.random(-20,20), part.CFrame.LookVector * -speed, math.random(-80,-50))

or something and the part will always go out of the same correct side no matter which way the main brick is facing.

#6

well you could go

part.Velocity = part.CFrame.LookVector * -speed + Vector3.new(math.random(-20,20), 0, math.random(-80,-50))

though I’m not really sure if that would work.

you should probably look through Explosion | Documentation - Roblox Creator Hub
because explosions may be another method to do it

sorry its taking so long to reply, I have school and can only look during breaks

#7

you cold also remove the gyro right after it adjusts the parts orientation

wait(2)

local part = script.Parent
local brick = script.Parent.Parent



-- this will be used to make sure your facing the part you want to avoid
local g = Instance.new("BodyGyro")
g.CFrame = CFrame.new(part.Position,brick.position)
g.MaxTorque = Vector3.new(500000000,500000000,500000000)
g.Parent = part
g:Destroy()
local speed = 50

wait(2)

part.Velocity = part.CFrame.LookVector * -speed + Vector3.new(math.random(-20,20), 0, math.random(-80,-50))

if this would work idk as I don’t have time to test it

#8

no good. It keeps moving in the same direction

#10

you have just to see the orientation of the part

#11 
part = script.Parent
brick = script.Parent.Parent
part.CFrame = CFrame.new(part.Position,brick.Position)


local directionVector = (part.CFrame.p - part.CFrame.LookVector * .01).unit
local velocity = directionVector * -100
part.Velocity = velocity
#12

actually there is a better way to do this


local power = 20
local height = 2

local part = script.Parent
local brick = script.Parent.Parent

part.CFrame = CFrame.new(part.Position,brick.Position)

part.ClickDetector.MouseClick:Connect(function()
	

	local directionVector = (part.Position - part.CFrame.LookVector * 1)+Vector3.new(0,height,0).unit
	local velocity = directionVector * -power
	part.Velocity = velocity
	
end)
#13

watch the power though because it will make that height of 2 become a height of 40 or more and you’ll lose track of it as it launches out of the atmosphere

#14

No good. I can’t get it to work.

#15

hmm that was the last idea I had

also maybe try to



local power = 100
local height = 2
local distance = 5

local part = script.Parent
local brick = script.Parent.Parent

part.CFrame = CFrame.new(part.Position,brick.Position)

part.ClickDetector.MouseClick:Connect(function()


	local directionVector = (part.Position - part.CFrame.LookVector * distance).unit
	local velocity = directionVector * -power
	part.Velocity = velocity + Vector3.new(0,height,0)

end)

also I added a clickdetector into part so I could activate it

#17

oh well It was worth trying, if you ever come back to it i would recomend trying to look through exposions api page and using them to fling object.

#18

After many hours of thinking and research. I have found this to be the method I needed:

.Velocity = CFrame.Angles(0,math.rad(math.random(-45,45)),0) * script.Parent.CFrame.LookVector * math.random(70,120)

The item you want to throw will start the code. The item you want to face in any direction is the parent of the script.
