Gravity flipping

Hi everyone,
using physics behaviour for sprites, i can set world gravity to a posite or negative values following the convention that positive values go from top to bottom of the screen

i was wondering if i could set world gravity along X axes (i.e. from left to right or right to left) insted of Y one.

Thanks in advance for help

Use the physics object --

ON Collision with object ->
      object.setWorldGravity -> -10(or whatever you want.)

thanks smitchell, but as i mentioned, issuing a value of "-10" flips gravity from bottom to top along Y axes, right?

i'd like to change gravity along orthogonal axes (X axes), i.e. to make falling objects from left to right of the screen

Can you not apply an impulse every tick? Would that not work..

thanks Yann i understood the trick involved in your example, it gave me the right input to my brain;

but maybe i should try a more robust way of controlling the gravity since i need to do a character/environement management with changing gravity vector
