How do I spawn objects around a planet?

Hi,

i want to add a world generator to my game that spawns objects randomly around planets. The objects should spawn at a specific distance because the planet has a range in which it pulls objects to itself with the platform behaviour.

Here is a screenshot of my game with a planet:

The red line shows where the objects should be spawned.

After they are spawned they will be pulled to the planet automatically (If they are touching the atmosphere) so everything i would like to know is how to find the right X and Y coordinates when the objects are spawned.

You should look at using parametric circle equations.

Then just spawn it at a random t-value between 0 and 2pi.

Thanks I'll have a look at that

Hi, aquadijoib! Thank you. That was excellent! How is the game coming btw? Screenshot looks cool. Would love to give it a testdrive. cheers!

bloodshot I'm glad it helped! I'm currently working on the crafting system for my game. I created a thread for that here on the forum. Also when the game is in a more finished state I would love to send a version to you for testing!
