you should add another little "sensor" sprite (without physics behaviour this time) attachet to the bottom of your main character sprite, then check for "onOverlapping" between sensor and the ground/objects

Gravity is a dark force

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

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

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
