Adding multiple things to the "ignore" parameter in raycasting?

Hey guys.

I would like to know how to add multiple things to the ignore parameter in raycasting, usually people just use player.Character but I have an issue where the bullets get stopped by other bullets, is there any way I can add both things to the "ignore" parameter or a possible workaround? (such as placing the raycasted bullets into the character?)

And for reference, this is what I'm talking about: local part, pos = game.Workspace:FindPartOnRay(Ray.new(tool.Handle.CFrame.p,(mouse.Hit.p - tool.Handle.CFrame.p).unit*999),player.Character)
