I’ve seen that done in a prefab for Medal of Honor. I don’t think the scripting that was used would work in ET. It was beyond my abilities to figure out though.
However, I suppose if you made a model with tags, it could be done. The model’s origin would be the origin of your planet’s rotation axis. Then have Tags attached to the model where you want the jump pads and spawn points to be. Put the model on a circular path to create the planet orbit, and then use faceangles in the script to rotate the planet around it’s own axis.
I’m not sure if spawn points can be attatched to tags. But perhaps if you used static spawn points that are only active when the planet is in position it would work. So if it takes 60 seconds for a full orbit, you could have 4 sets of static spawn points. Set the spawn time for 15 seconds and set autospawn to each new group of spawn points as the planet lines up with them during it’s orbit.
