The Official Scripting Ask Thread
Scripting

Wonder if anyone's yet made a script where the lift slows down if the next block is occupied, and then when the next block is clear, the lift speeds up. I know I've seen people request that as a feature but IDK if that would be possible to script.

The timewarping tools are located at the bottom left when you edit any function. Mess with those and you'll see what each one does. :)

It looks like Quartic is actually the default, which is a bump transition. You can use these in a few cases, and they're easy to make banked turns with, but I would recommend against using them too much. Create the equivalent transition using two Cubic functions instead. This lets you edit the entry and exit independently. It also allows you to add more pieces in the middle, like a constant roll rate (as shown in my ugly example). In the green segment, the roll is continuing to rotate to the right at 50 degrees per second.

The very last piece (that goes up and then back down) is simply the ToZero function. If it acts really strange, try to add time duration to it, or find a more appropriate place to use it.

I should also mention that if you're adding new track sections without everything lining up, this will cause jerks depending on what got cut off. (Track Sections are the ones on the left sidebar, not necessarily the "append" in the graph section.) If you have any graphs that are hanging off past the end of a Section, then when you add a new section it will get cut off, which can cause a jerk. Make sure everything is lined up before adding new sections. (Workaround: Make large portions of your coaster in giant sections lol.)

Ok, so names have been submitted and I think we've got a good selection to choose from.

BUT, they won't go to vote until someone finishes the supports. ;) Who's it gonna be??

Is there a way to zero out the track? I’ve been having issues with making the track level out after a helix, even after setting the roll back to zero.

Specifically adding onto this part, there's two methods you can try.

For a quick method of zeroing out, there's actually a built-in "ToZero" transition style in FVD. There is very little control over its shape, so it is best used in smaller portions of track (like the final transition into a brake run). It's not always perfect, so I tend to avoid using it in the middle of the ride itself, but it can still prove useful when you really need it. Especially if you are trying to line up track directly on an axis or plane at 0/0.

However, adjusting transition properties manually is best for a proper method. When you've reached a spot where your transition is as close to 0/0 as you can get, use the warping tools to fine-tune! Adjusting both the center and tension of the transition in tiny increments can have a decent effect on your final roll. Play with those, and maybe duration/force in very tiny increments to get exactly what you need. While it does take some time, tweaking all of these in 0.001 intervals can often get you that desired 0/0.

Honestly, playing with these features in general is very useful and often overlooked by those learning the program. They prove invaluable in getting the shapes you need.

Is there a way to smooth out transitions? The ones I’ve been messing around with have just come out rough for whatever reason.

Which transitions are you using? The default cubic should fare pretty well, unless you are making them very short with drastic roll changes. If you are lowering tension or using more linear functions, this will cause the ends of the transition to be very abrupt and Arrow-like, so it's generally best to avoid these unless you know what you're doing with them.

On the other hand, you can try using a transition, then leaving the roll rate constant (flat line), then using a transition to stop the roll. This will allow you to create a simple, less snappy transition. Roll rate takes some getting used to as a newcomer, so keeping things simple will help you get a grip on FVD.

And of course, the built-in smoother helps. Don't go nuts with it - small or tiny amounts are all you need. Going too far with it will actually create lumpy and jarring rides.
