I've manage to create a "some kind of" fluid character using castlevania sprite/animation. (Thanks to Uberlou for the tutorial)
I figured out than when you attack while in air the air control is stoped by my attacking animation.
Here's my capx : https://dl.dropbox.com/u/30148460/platformer.capx
(Arrow to move, Space to jump, W to attack)
I've tried a LOT of things and nothing seems to work. I've removed every frame but 1 and air control was ok. The more I add frame to the animation, the less air control I have until the animation is finished.
Anyone can help me ?
