Descent Demo v3

This is a collection of 22 structures and techniques which can be used to lower the elevation of B-Bot.

Version 3 includes:

• 7 more descending techniques
• 2 express elevators down so you can skip parts you've already done.
  
• Numerous improvements to help keep the B-Bot from accidentally falling.

Note: Most of the methods are one-way in that they can only be used to drop down. A few however can be used to go in both directions.

In order of occurrence with citations:

1. Free Jump. Tap on the far end of the platform, as the bot is traveling over the motor raise the slider to make him fly through the air. The first free jumping mechanism was discovered by @vince and used in his Jumpy level. @richardfu_ came with an improved version in Castle Jump (using 2 sliders). The jumper mechanism in the level is a smaller version than the one used in my Tiny Jump Demo (which uses a single slider & 2 draggables). @cpw came up with a version that uses only one draggable. I further boiled his design down to a 4 block variant.
2. Autopilot Slider Jump. Put the bot on the red brick block. Tap on the grass block, then very quickly raise the slider. The bot will climb over the raised block and leap off the end. I first saw this used in Richard Fu's Build Up level.
3. Motor Paddle Drop. When the motor paddle is horizontal step onto it.
4. Motor Elevator. Stop on the motor paddle when it's at highest point, then step off when it's at it's lowest. If first saw this in Richard Fu's Limbo level.
5a. Ball Elevator Drop. Gently launch the ball up and make the bot step onto it when it nears his height. First used in my Wharf Escape level.
6a. Floor Drop Out. With the bot on the metal block, move the slider to make him fall.
6b. Alternative: Slippery slider. With the bot on the motor, quickly move the slider to make him fall. For comparison, place the bot on the metal cube and move the slider. Note, that the bot slicks to metal cube but slips off the motor.
7a. Autopilot Slider Drop. Put the bot on the red brick block. Tap on the stair, then very quickly lower the slider. The bot will lose his balance and tumble off the stair. First used in my Witch's Cave level.
7b. Alternative: Mini Pagoda Drop. Put the bot on the red brick block. With the slider fixed in the up position tap on the stair. With a bit of luck, the bot will fall over the edge. This mechanism works but is a bit less reliable than method 7a. The nice thing about it is the lack of moving parts. The method was discovered by @meko and first appearing in his Mini Pagoda level.
7c. Alternative: Slider Launch. Use the Floor Drop slider to launch the bot over the cylinder.
8. Moving Slider Push. Put the bot in front of the moving slider.
9. Static Slider Drop. Top on top of fixed slider, then tap on the floor that the slider is resting on. You may need to change the viewing angle to actually tap on the slider. This is the smallest drop mechanism that I'm aware of (uses only a single block). I used this in my Seven Pearls level
10. Ball-on-Eye Leap. Tap the cylinder by the drop and the bot will leap over the ball and over the edge. You may need to walk over ball a few time for this to work. This mechanism works best with a cylinder on each side. First used in my Eleven Pearls level.
11. Squeeze-Jump. Tap on the stair block. When the bot get stuck under the cube block tap on the red brick block. First used in my Wizard's Spire level.
12. Spinning Motor Drop. Simply place the bot next to the motor and it will nudge him over the edge. A very small drop mechanism. I first saw this in Richard Fu's Limbo level.
13. Focus Drop (Autopilot variant). Tap on the draggable block, but move it before the bot reaches it.
14. Eye Drop. Tap on the cylinder. The bot will duck as passes under the eye. When the bot reaches the cylinder he'll put his foot down on the floor momentarily. At that moment, tap the floor. Note: The eye is the only block that reaches into the space of another block. First used on this level!
15. Ball Stack Drop. Put the bot on top of the ball stack, then gently nudge the ball towards the stack. When the ball hits the stack it will cause it to fall. The stack can potentially be many balls high. First used in this demo level?
16. Bot-on-ball push. Place the B-Bot on the ball, then raise the slider to release R-Bot. R-Bot will push the ball (and B-Bot) off the cylinder.
17. R-Bot Push. Place B-Bot next to the ball, then raise the slider to release R-Bot. R-Bot will push the ball which in turn will push B-Bot off the ledge. Initially I had used the "R's Head Bump" trick first used by Richard Fu's to get R-Bot push a 3 block bar (see Sneak In V), but was able to simplify the design here with a ball instead.
18. Bot-Sled. Hmm... how to get past this? What the heck!
19. Extra Credit: Tripping on Air. Place the bot on the red brick block, then tap on the half-pillar block again. When the bot is traveling over the grass block tap on the half-pillar block. @vince discovered this trick and used it in his Square One III level. This one is extra credit because it's particularly hard to do if you don't know the trick beforehand.

Also, the R-Bot stopper trick was first used by @Ricko in his Gate Operator level.

If you know that any of these were used in earlier levels than I've cited please let me know and I'll update the above accordingly.

@Frenzies That last one is extra credit. It's very hard to do if one doesn't know the trick.

Thanks - the bouncing ball is far more manageable now! And thanks for the extra techniques. I've added this new version to the index post of the tutorials thread.

Great compilation of techniques. Thanks

Amazing level. I love last step (pushing the metal piece)... Thanks!

Thank you. Great level..and tutorial

@Frenzies maybe because one is unachievable? Check out Ocean rocks

Wow... lot of thanks
