How to get knock a player back

Help and Feedback Scripting Support
#1

So basically i have a projectile, and i want to make it so when the projectile hits the player, they are knocked back.

I was going to use a BodyVelocity, the problem is i don’t know how to get the opposite side of the hit.

So what i can’t do is get the opposite side the projectile hit the player.

Any help is appreciated and if it wasn’t understandable you can ask me to explain it better. Thanks!

You could try making a ray from the player that fired the projectile to the player that was hit, then get the direction, convert the direction to a unit vector, like this

local ray = workspace:Raycast(Player1.Tool.Handle.Position , script.Parent.Position)
TouchedPart:ApplyImpulse(ray.Direction.Unit * 500)

This assumes that the projectile is a part and that this script ia parented to the part.

I have a part that will touch the hit player, so i think it would be easier to make something off the part that is hitting them.

local Force = -250
BodyVelocity.Velocity = TargetCharacter.HumanoidRootPart.CFrame.LookVector * Force

CFrames usually have a LookVector property, which basically takes the current direction where that specific part (HumanoidRootPart) is looking at

If you multiply that with a negative force, the Target’s Character would be pushed back

yes, this could run in a touched event.

Will test those out, brb :smiley:

Yes but @Faczki remember to destroy the bullet right after it touches the player or add a debounce so you can avoid any kind of repeated actions :slight_smile:

It is working but very weakly, what i mean is the player is not being pushed very far, i even tried puttin force in -2500 and it is still weak.

Have you tried setting the MaxForce property to math.huge?

BodyVelocity.MaxForce = Vector3.new(math.huge, math.huge, math.huge)

ADDITIONALLY, you can use the Debris:AddItem() function so that you don’t have to worry about destroying it later on

local Force = -50 --We don't want to make this literally send the Player to Brazil

BodyVelocity.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
BodyVelocity.Velocity = TargetCharacter.HumanoidRootPart.CFrame.LookVector * Force
game.Debris:AddItem(BodyVelocity, 1)
