How would I make a part travel in a linear path and then kill something when it hits?

I’ve been making a knife for a while and I made it so that the knife travels instantly.
I have tried using roblox’s throwing knife thing but it doesn’t work.

You could perhaps use an AngularVelocity to turn it in midair, a BodyVelocity to make it fly in a linear path and then anchor it when it doesn’t hit a player.

BodyPosition instance to make something travel in a linear path and then “Touched” event to detect when it hits.

Planning on using FastCastRedux. Thanks for the help anyway.
