Ho I think I understand now you mean when you use a skill they alway appear a weird animation when you cast the skill (like a flash)?
If i am righ it is because you need to edit this keyword~
"NORMAL_SKILLS" => ["SKILL_ACTIVATE","SWING_R","DAMAGE_ANIME","CO_RESET"],
"NORMAL_MAGIC" => ["MAGIC_ACTIVATE","SWING_R","DAMAGE_ANIME","CO_RESET"],
simply remove the skill and magic activate~
or replace it by what you want for make you skill more cool~
and normally when you create a new skill you not supossely have this kind of problem because you create a new chain of skill it is because you don't input them in the configuration~
and if you want to remove the horrible delay animation when you use skill or magic (and the actor wait)
"COMMAND_MAGIC" => ["STANDBY","MAGIC_WAIT"],
"COMMAND_SKILL" => ["STANDBY","SKILL_WAIT"],
remove the magic_wait it is a anime setting~ who use animation
