Convert Scratch direction to "normal" trig :)
I'm having a brain freeze here 
What to I have to do to convert from Scratch Direction (90=right,0 =up etc ) into "normal" maths (0=right,90=up etc )?

Re: Convert Scratch direction to "normal" trig :)
Do (90 - (Scratch direction)) to get "normal" direction.
So, pointing 90 Scratch degrees (left) is 0 normal degrees.
Pointing -90 Scratch degrees (right) is 180 normal degrees.
Pointing 0 Scratch degrees (up) is 90 normal degrees.
And pointing 180 Scratch degrees (down) is -90 normal degrees.
