How to make a particle emitter for all players?

hello i want to make a particle emitter on the torso of the players but i only get it in studio how can i fix this issue?

this is what i have

 local speed2 = Instance.new("ParticleEmitter",Workspace.Player1.torso)

Well first it would be a good idea to make sure the Player and it's character have loaded in. Then you'd be able to implement a particle emitter into the torso

Here is a fast and efficient way of completing the statement above:

game.Players.PlayerAdded:connect(function(player) 
	player.CharacterAdded:connect(function(char) 
		if char then
			local torso = char:FindFirstChild'Torso'
			local speed2 = Instance.new("ParticleEmitter", torso)
		end
	end)
end)

Note: This should be put in a Script, not a Localscript
