centerx: the X coordinate of the shockwave's center, expressed as a percentage (0 - 100) where 0% represents the leftmost part of the image and 100% the rightmost one.
centery: the Y coordinate of the shockwave's center, expressed as a percentage (0 - 100) where 0% represents the upper part of the image and 100% the lower one.
radius1: the radius, expressed as a percentage of the object's width, of the outermost part of the shockwave.
radius2: the radius, expressed as a percentage of the object's width, of the innermost part of the shockwave. radius1 - radius2 is equal to the thickness of the shockwave.
distortionstrength: the strength of the distortion, low values are recommended.
chromatic offset: the offset of the shockwave's chromatic aberration effect. Larger values result in more chromatic aberration. Very low values are recommended. Use 0 to remove chromatic aberration.
ring blur: smoothness of the shockwave effect. Low values result in a sharper look.
