Uhm well the problem isn't really in the resetting of the values, construct seems to not completely recognize the robot once the layout restarts :
The red particles on top of his head vanish and come up only when I jump, same for the red line,
and the FallState instance variable in PixBot seems to uh... Increment forever without resetting to 0 when Pixbot hits the ground.
I think I broke the Matrix.
