Launching a body - key binding
« on: July 16, 2016, 03:32:39 PM »
I followed tutorial 3 on launching bodies at Mars. I get to the step where Iím supposed to target Mars (put the crosshairs on it, right?) and press the 2 key to launch Mimas at it. Pressing the key did nothing. I think this stalled the tutorial before it could end.

Playing around taught me two things:
  • The number keys get bound to launching a body only if you select it in the Add palette and press a number key: Select Mimas, press 2, and from then on the 2 key (in Add/Launch mode) will launch Mimas.
  • The launch speed (by the time I noticed the option) was set to 10 km/s. This is a radial velocity. +10 km/s sends the body away from the target (if it doesnít escape, I guess that provides a nice sense of foreboding). Change the sign to minus to throw the rock toward the target.
