Seeing Stars

For background, see @Labyrenight's level Star Pass (demo) and the discussion here: Star Pass.

Spoiler: Notes about the Star Pass technique

In certain situations a star that is captured by a moving object (or a stationary object attached to a slider) can make metal objects and eyeballs "invisible" to bots, so they will climb onto objects they normally couldn't.

Thanks to @Labyrenight and @Denis Nazin for doing all the research on this technique. There are many interesting demos at the Star Pass discussion linked above.

Thanks! Excellent mini level. I love these levels. I hope the players will understand the "star pass" principle.

I completed it but I am sure that my way to capture the stone star is wrong. How to get that star?

I don't know the purpose of stone pillar and the metal underneath.

Thanks, @Denis Nazin! I figured it would be good to post some mini-levels that demonstrate a few of the ways it can be used. I've got another one I might post tomorrow.

Have B stand at the bottom of the ramp so that when R pushes the ball, it gets blocked by B's head. Since the ball has a star on the side that hits B's head, it makes B's head "invisible" to R such that R will just see B's body and will climb onto it (because it's at the level of the path). Once on the eye, R will step over to the ball and then the stone.

I see now that I should have put the star on the other side of the ramp because a BB can be used to get it where it's currently located. Is that how you got it, or did you use another method?

Thanks for playing!

Now that I see the intended way it was very clever and combined with the star pass I think it deserves 5 stars. My method - let B stand on the round draggable, slide in slowly so B's body leans towards the stone block and capture the star before B goes up. I will never use BB in any level.

Same as @mastersifu but I do it by sliding quickly.

I didn't know the star on the ball had 2 uses. one of them is for B's head, even though I gave the demo

Are you referring to the column above B's starting position and the metal below B?
The metal below B is a blocked lift that lowers B slightly. Without it R was doing unpredictable things when stepping into B. Regarding the stone column, I think I should have removed it. During one of my tests R rode the ball down to the lower level and then turned and grabbed the star on the grass. I wanted to block that so L would be the one to grab the star. But then in later tests R never rode the ball anyway, so it probably wasn't a huge concern. Thanks for playing!

@Labyrenight - Yes, I borrowed that idea directly from your demo!

@mastersifu - Got it. I should definitely have put the ball on the other side of the ramp. The silly thing is I had it there originally, but thought it looked better in the middle and moved it!

I think one has to be a level builder to be excited by these star pass effects. But i quite liked the level and the the move to get the stone star was excellent especially as i couldn’t see what benefit there would be to blocking the ball.

I'm glad you liked it, @ridgerunner! Thanks for playing.

Fascinating!

Although I am afraid that my solution is like @mastersifu ,I saw your picture so I played again & found the intended tricky way... 5 shinny stars for you... thanks for sharing @MekaSage
