Explosion but without the explosion?

im not really asking for scripts but if you could tell me how to make a script so then i can step on a landmine but instead of the explosion visuals i get the particle explosion that i have working but still have the power of the explosion to fling me and kill me

I am not so confident with what I came up, but I will share it anyways.

Step1. Go through every player close to that landmine when someone steps on it, and return the magnitude like this:

local Players = game:GetService("Players")
local function explode(hit)
	if not hit.Parent:FindFirstChild("Humanoid") then return end
	for i,v in pairs(Players:GetPlayers()) do
		if v.Characer then
			local humRoot = v.Character:FindFirstChild("HumanoidRootPart")
			if humRoot then
				local distance = (script.Parent.Position - humRoot.Position).magnitude
			end
		end
	end
end

script.Parent.Touched:Connect(explode)

Step2. Determine whether to kill player, by comparing the distance to the value of how close the player should be to get killed. and if not kill, fling the character by using the body force.

local Players = game:GetService("Players")
local maxDist = 100
local killDist = 20
local function explode(hit)
	if not hit.Parent:FindFirstChild("Humanoid") then return end
	for i,v in pairs(Players:GetPlayers()) do
		if v.Character then
			local character = v.Character
			local humRoot = v.Character:FindFirstChild("HumanoidRootPart")
			if humRoot then
				local distance = (script.Parent.Position - humRoot.Position).magnitude
				local Humanoid = character:FindFirstChild("Humanoid")
				if distance < killDist then
					--Kills player
					if Humanoid then
						Humanoid:TakeDamage(100--[[Damage Player]])
					end
				elseif distance < maxDist then
					--won't kill, but will fling			
					local BF = Instance.new("BodyForce")
					BF.Force = Vector3.new(math.random(-1000,1000),10000,math.random(-1000,1000)) --Flings in random direction
					Humanoid.Sit = true
					BF.Parent = humRoot
					game:GetService("Debris"):addItem(BF,.1)
				end
			end
		end
	end
end
script.Parent.Touched:Connect(explode)
