I've got a problem with my project I don't have with the 0.98 with the physic engine.
I've done some tests and it appear that you can test yourself with a simple sprite, with the physic behavior.
Here's the problem :
Wih the 0.98 :
In the event sheet, a simple event to create the sprite when the user press space key.
If you setup the world gravity to -20 (for example), the first sprite created when we push the space key, starts flying to the top of the screen (normal with a negative value).
With the 0.99 :
With the same parameters, the first sprite don't fly, if you press space again, the second don't fly, but at the third sprite created, that's work...I have to wait for 3 sprites beforce gravity takes effect....
Thx in advance.
