How do i get the opposite direction of a position relative to the player

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

  1. What do you want to achieve? Keep it simple and clear!
    Hello, im trying to make an ability for my fighting game, that is supposed to knock all players away from an explosion, this is how it looks like right now

basically, i want it to knock the players ragdolls away from the explosion relatively to the explosion’s position

  1. What is the issue? Include screenshots / videos if possible!
    i have no idea how to do that, i would be thankful if someone could provide an example how would i have to do it
  2. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    yes, i tried looking for solutions, but i dont think there was a similar one close to my case
    basically after this line its supposed to knock back, but i dont know how to do that
local EnemyCharacter = AttackHitboxes.CreateHitbox(Character, Vector3.new(20,20,20), 3, true, HumanoidRootPart.CFrame, false, nil, nil, true, 3, nil, true, 3, nil)
			
			local KnockbackAttachment = Instance.new("Attachment")
			KnockbackAttachment.Parent = EnemyCharacter.HumanoidRootPart

			local KnockbackLinearVelocity = Instance.new("LinearVelocity")
			KnockbackLinearVelocity.Parent = EnemyCharacter.HumanoidRootPart

			KnockbackLinearVelocity.MaxForce = 9999999
			KnockbackLinearVelocity.Attachment0 = KnockbackAttachment
			KnockbackLinearVelocity.VectorVelocity = Vector3.new(0,0,0) --i need to set the velocity so the character flies in the opposite direction of the explosion
			--knock the player's ragdolls away from the explosion
			task.delay(0.2, function()
				KnockbackLinearVelocity:Destroy()
				KnockbackAttachment:Destroy()
			end)

(this returns the enemy character who was hit with the attack)
if anyone knows how to get the needed direction, thanks!

Hello guys, i found this forum post - Explosion push force relative to explosion center? and solved it using it.
