Hey @Randam you need to give us more info. What version of BB are you using, what template, what are you trying to do with the timeline editor, are you in a scene or are you in a UI? Gotta give the details if you want some good help.
i am using bb3 beta ad i am using default template in bb i have created i know 3d world and i want to edit the scene that one particular scene just come only 1000 pixels just like the line zen
I'm going to let someone else answer here. I haven't had time to really play with BB3 beta. Still working on making Trixel Rocket a better game. Hopefully I will get to a point that I can move on to playing with BB3.
