I could not find a function sinw or cosw. Were did you stumble over them? Lemme have a look at it. Are you sure they haven’t been used as variables? w could be an abbreviation for the german word “Winkel” meaning “angle” (in degrees or radian).
hi blackreaper… this is quite an old post but yes you can control aspects of you shaders through the ge… you can for instance press a key and change the tiling or blend something over time etc… even move it around the screen… only problem is you can’t get the values back out again… but you can still do way cool things with it…
