I'm trying to make a lightsaber slider for the unlock screen.
I want it extent the lightsaber as you drag your finger across. I tried having the the lightsaber as the background part and a long black slider that would gradually show more of the saber but since the slider is large, it stops sliding at the end of the bar. Is there a way or setting i can change to make it slider farther, like off the screen?

Any other ideas to make this work would be appreciated as well.
