These are settings that can be applied to all ride types.

Each ride has it's own unique settings as well, you can see those on their individual wiki pages:
Carousel • Chairswing • Ferris Wheel • Jets • Drop Tower • Teacups • Pendulum • Swing Ship • Star Flyer • Enterprise • TopSpin

Use /rideadm <ridename> setting <settingName> [value] in order to set these settings.

Setting types:
Integer = a whole number, eg 6
Double = a decimal Number, eg 5.75
Boolean = true/false
Material = Valid Block Material Name
Entity Type = Valid Entity Type Name
Location = In-game coordinates

Leaving the value blank uses your current location, otherwise use the syntax [worldName] <x> <y> <z>
