latform behavior: animation triggers 'On jump', 'On falling', 'On landed', 'On stopped' and 'On moving'. These should significantly simplify events for animating Platform characters.
Looking forward, how about the sliding trigger? This trigger can be used for ladders, ropes, and wall sliding like megaman.
The only way I figured out to make the sliding pose match perfectly with the megaman and mario style was using two objects, one with the plataform behavior and another with no behavior, making the player stop when touch the wall, ladder, etc. The second object need to match the player position everytime it touch a wall, and the player need to update his X and Y when releasing the pose.
