how to edit staging

orbital321 year ago (3 edits)

Place the parts of the rocket you want as stages.
Click the button in the bottom right that says "Stage Mode". Stages work from 0 to 5, 0 staging first and 5 staging last.
After clicking on the given number, click on the parts you want on that stage. The part should then turn a different color.
When done building, launch. Press space to activate the next stage. Remember, 0 to 5.

ah, thanks! i appear to be having problems setting certain parts as stages, as when i click the object, it doesn't change colors, i'll try the scratch version

hm, that's a bit odd. seems to be working fine for me. I mean it could be a lag related bug, but to be fair the more gray a part is the harder it is to see the color change. let me know if you find anything out. thanks!
