How do I use multiple If's in Lua?
<p>I'm trying to make a UFO in my ROBLOX place, and wanted to create a system that would play an audio when the UFO passes overhead. I created a part, inserted an audio into the part, then placed a script within the part. So it looks like:</p>

<p>Part->Audio->Script</p>

<p>I plan the system to register when a Humanoid is touched, and if the part is going faster than say, 300 Studs per second, I want it to play an audio (preferably the audio would be played only for the person(s) that was touched by the part) so I wrote a script that goes as follows:</p>

<pre><code>while true do
if script.parent.parent.Velocity.Magnitude&gt;299 then 
    script.Parent:play()
    wait(5)
    script.Parent:stop()
else
    wait()
end
wait()
</code></pre>

<p>end</p>

<p>As you can see I'm missing the part about the humanoid being touched, but I'm not sure how to write that. I'm really new to scripting, and I don't know the proper context for these commands(?). Help would be greatly appreciated.</p>

<p>Thanks!</p>
