How do I fix animation problem ?

Hey,

Sorry for vague title ! I'm trying to make simple animations with my character and monsters, like running, jumping, etc. But it seems that the events "is on floor", "is landed" and that kind are taking in account the pixels of the frame and not the frame itself. So basically, when a sprite is running, everytime it steps are not colliding with floor, it's considered to be in air. Not to say this gives me a hard time since it's supposed to have some animations while in air.

How can I fix this ?

Maybe try playing around with the sprite's collision polygon to make it more consistent.

It doesn't seem to be this, if the collision polygon is set to bounding box it's the problem described on my first post, if it's another shape my character will keep falling.

To bounding box on all animation frames ... with the origin on the same place in all animations and in all animation frames ... with all animations frames beeing the same size ... ?
