... explaination : stair will cause program of R bot to read what is the next block to be stepped at front but below. below the grass at front of 1st stair, there is a pipe which is cant be stepped by R. the weird thing is happen at the second slider. I put a fence ontop of slider, the same case with first grass block, if you put that fence below the grass, R will turn to 4th stair. BUT, when you put fence at below of 3rd stair, R consider itself, able to step on that fence, which then R will walk back to 3rd stair then reach finish. this method discovered by @Riyanda Ahyaritama here are another cards that showing common or normal case of unstepable conditions for R through ball or through double stair, (unstepable grass is new thing)
@Ray Aznable - This isn't new behaviour as I've used it years ago. R will not pass a block with leading stairs and a rail underneath. The second one is new as I wasn't aware the fence would turn R. The last has been around for years too. R will not pass the 2nd stairs if there is not block under it. I used it many times, even harder to figure out when B's pillar is the block.
there are 4 stairs in this demo card what u meant by 2nd stair is it the 3rd one near winblock? ok that side by side stair is an old case too, R will not pass next weird faced stair if there is no block below of it, but this is a fence, why R could pass it? but R couldnt pass square block when fence below. and what u mean by B pillar? R doesnt want to pass side by side stair if B pillar head being put under it?
I did some testing, if you change the fence starting spot, the move doesn't work. Did you know the in the first move, if you swap the rail and slider around, the lift has no effect? I seen that some time ago. When I said 2nd I mean at the far end or 3rd stairs. As for pillarB, if pillarB walks under the 2nd stairs that is open, R will pass just like the fence fills the spot, B's pillar fills it. I had a level a long time ago called Pillar Filler and used that move.
... @Meko Guy Spoiler: Pillar Filler Spoiler: The Right Height thats because, first position of slider tube is considered as a void block. if you remove the pipe, slide tube in reposition condition as u said before, still working. no more void slider tube.
... @Riyanda Ahyaritama to help reduce more new members who using zappers and free dragables. your discovery is unique hopefully will make them interested to build simple logic level with start with this.
@Ray Aznable @Riyanda Ahyaritama - It appears to me that you uploaded a level with someone else's name on the card without their permission .
@Riyanda Ahyaritama - She did that before with me but only had my name on her card so I asked for it to be deleted.
