Assuming that pressure pulses in TPT can be considered "sound", the speed of TPT sound is about 3.2 pixels per frame. I made some pistons going at this speed and then some slower ones to illustrate the difference, at 2 and 1 p/f. Use pressure display!

good job

00yoshi, that number works perfectly! With that number the speed of sound in TPT and real life are the same! This is incredible, now we finally know how big a pixel is!

With one pixel being approximately equal to 1.8 meters, assuming one atmosphere of dry air at 20 degrees Celsius.

3.17523739973 is the actual average value that I got from my tests, for anyone who's interested. Also, more tests could help provide more accurate data if anyone wants to do that.

Air can actually travel faster than this, but it'd be silly to try and measure it. xD There are a few odd situations when velocity difference is too high, and air will actually skip enormous gaps.

I could make a non-moving diagram, so the TPT pixels would not matter. I might post it on here with much credit to you.

@00yoshi: how do you change the game files?

i would like somone to check my math but i've came to a final number 1 pixel = 2 yards

thanks bristrees, im doing the math and i am almost there
