I had a litte free time so here are some updates:
2019.09.01
Added /fixed the following informations to the manual:
*~ Added more info about DUCK
*~ Added DUCKING, DUCKRISE, EDGE, BACKEDGE, LOSE, VICTORY, BACKBURNPAIN, BACKSHOCKPAIN
DUCK {players, enemies}
*~Optional.
*~This will only play in a stage whose max and min 'z' are the same (In other words, a 2-D stage).
*~Plays when a player presses down. They can use this to duck under high attacks.
*~This animation is also played if player is under platform which is shorter than his/her height. However in this state, player is forced to play this animation instead. In this state, pressing left or right only changes direction.
*~While ducking, player can perform either SLIDE or DUCKATTACK (see below).
*~If DUCKING is present (see below), this animation will play after it.
*~For enemy that use DUCK you can use "range {min} {max}" animation command for custom DUCK when the entity is in that custom range.
DUCKING {players, enemies, NPC} (6330+)
