I'm trying to make a realistic gun, and the bullets are propelled using lookVector. The thing with lookVector is is that the bullet has to be facing the target destination, in this case, where the mouse is pointing. This brings me back to the original question: How do I make a part point in the same direction that the mouse is pointing in?
No guarantees, but:
game:GetService("RunService").Stepped:connect(function() part.CFrame=CFrame.new(part.CFrame.p, mouse.Hit.p) end)
That SHOULD work, as it's something i've been using in my code for a while, just simplified. To work correctly, the part must be anchored.
