Simulating 2D planetary gravity and trajectpry using Unity
I'm making a game that has planets rotating around a sun.
The player fires objects, spheres, etc from these planets that are influenced by the surrounding planets. My question is if there is a way/tutorial to predict the trajectory that these objects would take using line renderer, etc.
Something like this.

Also if anyone can point to some good tutorials for implementing a planet + sun system in unity that would be great.
I don't know if there are any tutorials, it should not be too hard in 2D. You may try the following;
create shapes for the sun and other planets. Assign a size to each of them.
at the start of scene, you would store them in a list, their positions and gravitational effect (caused by size), in a Vector3 for example.
when you shoot, bullets for example, it would be effected by this gravitation on every update. Simply you would measure distance of your bullet from a planet, then the force would be (baseForce * sizeOfPlanet) / $$anonymous$$athf.Pow(distance,2).
you would create a loop, and the above would be applied by each planet.
I hope this would help.
