The "ish_flingtrail" particles is used by THE GOO BIT.We can build a rectangular coordinates system and the center of the bit is ( 0 , 0 ).So the images of "ish_flingtrail" appear at ( 0 , 0 ) then fall in straight.How can I modify the particles and let the images appear at ( x , 0 ) or (-x , 0 ) then fall in straight?
