Use the right sin and cos functions.
If you try to draw a sine wave in scratch it'll give you a cosine wave, and a cosine wave will give you a sine wave. I think scratch should use the proper trig terms. I have no idea why it's reversed anyway, can someone spread some light on why?

its heinously stupidThe only reason I can think of is that sin comes first in the drop down menu, and x does too.
i know scratch's directional system is messed up so that might be why
scratch's "north" direction is 0 degrees
but that's usually 90 degrees. 90 degrees is also the offset between a sin wave and a cosine wave, so im assuming thats why

I guess that kinda explains it, but that raises another point, why have such a strange direction system, while it would take a while to adjust scripts for a normal system, it'd simplify them

True, but things like this have happened before. I saw an old project that used the comment blocks, rather than the side tags, if you played it in java or offline the script would stop running at that point.
