There's a number of levels called "Crazy Train" by different authors. Basically, the whole level is set inside a train that appears to be moving constantly forwards and you jump from carriage to carriage. It's an interesting concept because obviously there's a limit to how far an object can move before hitting a wall but there seems to be no limit and it keeps moving continuously. What actually happens is the train is stationary but the floor moves to the left and gives the impression that the train is moving. From what I can gather an emitter sits at the far right of the level emitting a large platform which acts as the floor, it has two wheels on it which move it along to the left. I've tried many times to make my own version of this but I just can't get it right. I've made it emit a platform which travels to the left but I've found that each object has a small gap between the next. This is caused by the fact that it takes time for the motorbolt to build up speed and the minimum 0.5 delay. I've tried increasing the linear velocity to give it a quick initial speed but this seems to have poor results as the object bumps into the next in line and causes that to shunt forward still leaving a gap. I've tried compensating for this by having a quite complex latching system where the object latches onto to the other preventing it from coming apart. Whilst this did improve the situation slightly I found that sometimes the latch sometimes didn't want to go inside the other one and left an occasional gap between platforms again. Another problem I had was that the platform when it was sent away at speed would sometimes go off at an angle. This may be because of the position of the emitter, perhaps I need to place it in a central position? I did try working around this by having a 'rail' which the platforms travelled along to stop them moving in any other way but horizontal but even though the rail was made of glass sometimes the platform would get wedged and bring the whole thing to a stop even though the gap and the rail were the same size! Is there a solution to how I can get moving platforms to properly merge together?

A long time ago I made an infinite terrain level and explained how to make it (I also give away the parts in the level as prizes). Here are the links : https://lbpcentral.lbp-hub.com/index.php?t=t=4475 https://lbpcentral.lbp-hub.com/index.php?t=t=4422 You can check it out and come up with a better version for the concept. Many creators here have also made similar levels. Vanemiera's "Kikaiwa: Strain of Life" is one I consider to work much better than my own, and it's set up to be much faster. You could try to ask him how he did it (I don't know if he comes onto these forums much anymore, which is a shame because he's a really great creator). Hope that helps.

Take a look at my Crazy Train. I have an triple infinite scrolling background on that one, each one going at a different speed. Seriously, you seem to be on the right track. The way I got it to work is pretty simple. I'm emitting the pieces of background as horizontally as I can by placing the emitters well and I tweaked the velocity precisely until the pieces stack together without any spacing. Seriously, it's all about precise tweaking. It can be alot of work (especially if you go crazy with a triple background like me) but the effect is worth it at the end imo. .

Thanks. I've managed to do it after tweaking the settings and repositioning the emitter until it works just right. There is a Crazy Train template that I found after making mine and it seems to work exactly the same as how I'd done it. The author of the template found a clever way of getting around the minimum 0.5 second delay on the emitter by having a floating object that just continuously triggered a switch very quickly that was linked to the emitter. But I managed to get mine working even with the delay.

The minimum delay on an emitter is actually 0.1s. You can reach it by using the analog stick instead of the D-pad IIRC. Good to hear you've got it working though.
