Planetary Gravity

Hello. I want to port my game from unity to Godot. And my game uses planetary gravity. I know that it is a simple way to make this thing into Godot. How to make planetary gravity with areas?

You first have to change the space override mode. When set to AREA_SPACE_OVERRIDE_COMBINE ("Combine" in the editor) the area will add it's gravity and damping. There is an option to make it a point source. When enabled the gravity vector is the center of gravity instead of direction. Use gravity_distance_scale to change how fast the strength of gravity decreases with the square of distance.

Ok, I've changed space override mode but other object just failing down. Here is the screenshot. <img src="https://pp.vk.me/c626320/v626320154/26781/a2m3DOF1f2o.jpg" alt="" title="Image: https://pp.vk.me/c626320/v626320154/26781/a2m3DOF1f2o.jpg">

Well I got it to work buy setting the Gravity Distance Scale down to zero, and setting the Gravity Vec to (0,0,0) heres the screen shot <img title="Image: https://s16.postimg.org/hp67eahf9/Kazam_screenshot_00002.png" alt="" src="https://s16.postimg.org/hp67eahf9/Kazam_screenshot_00002.png">

I should have sayed more about gravity_distance_scale. You should use small values. With a value of 100 the effective range will be something like 0.01. And the damping should be set to 0 as ist will affect the overlapping bodies.

That's working. Thank you. And how to set global gravity vector to zero (no global gravity)?
