More of an NPL experiment than a truly playable custom level, I present to you this:
Stay on the paths and the next one lights up ahead of you. Step off the paths and you lose.
(Why is everything looking non-LRR-y? I'm running Time Raiders, partly to show it off )
I haven't bothered to tidy everything into a plug-n-chug format but everything is indeed usable right here, if you want it (should run fine on vanilla LRR).
The interesting bit is of course the NPL and tutorial block map. The tutorial block map has the LRR at 19 and counts down to 1 on the tuto block in front of the Command Ship. The NPL is put in a spoiler here:
The interesting bit is the usage of a loop to find which tile the LRR is at. Then just subtract one from that and put a power path down on the next tile. If it couldn't find the LRR on any tutorial tile, fail the level and send monsters out.
One would suppose that if I were to put the lines
TRUE ? SetTutorialBlockIsPath GetR1
TRUE ? SetTutorialBlockIsPath GetR3
next to the other
TRUE ? SetTutorialBlockIsPath GetR2
the game would work flawlessly, making power paths ahead, on the raider, and behind. Except it doesn't, and won't do what you want at all, spawning no power paths instead of three. My theory so far is that when the game sees a SetTutorialBlockIsPath command it will no longer execute any more SetTutorialBlockIsPath commands for that run of the NPL. This isn't the first instance of the NPL playing up, and I've noticed that re-ordering lines will actually change the outcome (even if all you switched was TRUE ? AddR1 1 and TRUE ? GenerateSlug).
I have two further comments to make:
1) Perhaps this would be more playable and more fun if the game didn't point out where the next Power Path was, and you had to get it by trial and error. That's easy to do; on the SetTutorialBlockIsPath line change GetR2 to GetR1. However, this also might be incredibly trolling...
2) Why is the maze so short, I hear you ask? With @Cyrem's map creator there's an arbitary limit of 20 tutorial blocks (Thank you so much for your utility Cyrem! Nothing would be possible without it!) Is there any chance this could be... increased?
