creating a ferris wheel but cant get it to stop and start | Forums

[rlmergeuser]

i am creating a ferris wheel that my rider will enter, go around and exit at the top, however as the level starts the wheel automatically begins to spin. i am using a rotational hinge to make it spin and as its hovering in midair i cant assign a physics event trigger and an area trigger to delay it starting because the whole thing comes crashing to the ground. please help me get round this as its starting to really piss me off.

thanks in advance

Are you applying a force to the hinge to turn it? If so make that be pulled from a variable data source, and set it to zero, then make a set value event to change the number in there to the ammount of force you want, and have the set value event triggered with a hit trigger or area trigger when the rider enters the wheel.

I'm not using any force to push the hinge. It just automatically starts under its own momentum with the angular force enabled. Is there any way to disable angular force but still get it to spin. I'm new at the whole track editing thing so variable data force and set value events make no sense to me. I have checked the video tutorials and still can't work it out.

You need to turn physics off for the object your ferris wheel is attached to, that will hold it in the air.

Once that's done you can use a trigger and a physics event to start it, same again to stop it. Just ask if you need more help.

I've tried disabling the physics but with no joy. I don't know what I have done wrong as I have followed the tutorials to the letter.

What's the ferris wheel attached to?

In the physics joint options, have you checked "disable collision"?

Disable the physics on the entire ferris wheel, structure, everything.

Then set an area trigger >>>> physics event >>>> ferris wheel (the moving part, presumably a glued object).

That should work how you want it to.

Also, check out the below thread for tutorials with simple flow charts explaining how to set things up. Requests can be made as well, so if you were to need something specific it might help you out.

There is a tutorial for a physics event lift, which is basically the same as you are attempting, only with a slider instead of a rotational hinge. So it might help you to check your logic is all set up correctly.

Here is a fun way to do it that rarely malfunctions...
Set out a variable data source. Then go to your physics joint and note what your angular motor velocity is. Use y button to select value target and choose data source. Now put out a set value event...target is variable data source, value is whatever angular velocity was. Now the wheel sits ready to ru...use any triggers to "set the value" of the data source, turning on the motor to turn off have a separate trigger and set value event to make the variable data source zero again. Good luck! MSG me if u can't get it.
