function SlideForce(Character)
	
	local HRP = Character.HumanoidRootPart
	
	local Force = Instance.new('VectorForce')
	Force.Name = 'SlideForce'
	Force.Parent = HRP
	Force.Attachment0 = HRP.RootAttachment
	Force.RelativeTo = 'World'
	Force.Force = HRP.CFrame.LookVector * 200
	
	task.wait(SlideTime)	
	
	Force:Destroy()
	
end

I have this function that does create the vector force and put it in the character correctly, but no force is applied in game

Force.Force = HRP.CFrame.LookVector * 200

You need to set the player assembly mass * workspace.Gravity + 200. It’s probably that your force is too low

if i set it to a higher value, it only works if the player is in the air
