How can you make an with it's own gravity?

Hello, I am attempting to create a game where objects are effected by the gravity from other objects. I don’t know a lot of programming but am willing to try some things out if it is needed in order to do this. Basically, I want to create planets that will pull a projectile towards them or around them into orbit, in other words, how can I make an area of effect gravity-well that will pull objects towards them. I have tried using the Radial Force blueprint component to do this, but even though I have set my projectile’s physics properties to projectile, and set the Radial Force to apply force to projectile type objects, it doesn’t seem to have any effect. If there is anyone who knows what I am doing wrong, or could give me some instructions on how to do this I would be very grateful.


I have HEARD that this can only be done in C++ at this point.
