Because it's too limiting to be of any use (I think), especially since it only works once when the level begins. It might be usable if the sliding R could repeat that move. I'm not sure if it's possible to pause the slider and only trigger the kick when the slider starts to move again
I think it's because of the head rotation. If you look closely at the level card and at the start fo the level, you'll see that the fence is on the other side of the R bot. This happens in every head, but sliders aren't meant to be rotated, so it spins back to its original position. But this is just my theory, and as for why, see @cpw's comment above.
@Frenzies I think there are other bugs that also involve such "direction flip". It happens usually when you try to attach a bot onto something that is supposed to move by itself (slider / motor), and the game renders it in such a way to "counteract". Though as far as I know they only work once when the level begins......
Here's a related discovery of Push-glide (you'll need to jump to initiate autopiloting). If you add a ceiling (or balance the center of gravity of the free block) you'll see B lifting the block in the air until you tap on the white background. Otherwise (as shown below) he would be strong enough to rotate the block onto the Win Spoiler
Spoiler Here's one I made before. Decided to post it because I was bored, and maybe someone might be interested in it. Just lift the platform upward, tap on one of the grass blocks up there, then pull it down. Note that it doesn't work all the time, but it does work most of the time.
Here's the self-destruct block mechanism I came up with while making Catch Me If You Can. The basic idea is to add a ball-slider trigger right at that ground block so that you can only step on it once, then the block would fall and you can't go back anymore. There's a considerable lag in between though, so I guess the ball trigger should be placed somewhere earlier (or designed for R's slow walking speed). The ball also doesn't always get pushed depending on the starting spot / destination of B, so you'll have to test and make sure his path movement would impact the ball. Not as perfect as a block that would inherently self-destruct, but just to make use of blocks we currently have Spoiler
Nice idea! It actually reminded me what I tried earlier to make bots stably knock over balls, and I think that can stabilize your mechanism. Spoiler I attempted to use it in my Expedition V but it took too much space, so I ended up using a simpler one.
That overhead wedge worked like a charm Though I agree, it takes up too much space for just removing one block in the path.
Another nice one! The good thing is how compact it is (though you'll still need the empty space to allow it to fall off) and that there's no time lag.
Spoiler: What slider? Here's a bare bones sliderless version. Many techniques which cause B-Bot to change elevation, besides simple sliders and stairs, are one-way mechanisms too.
