Help wanted for Spinning Columns in Trials | Forums

[rlmergeuser]

Trying to make a track consisting of spinning columns in Trials HD. Got one made but it speeds up and slows down on its own. Put three together and they bounce off each other and go MENTAL. Each column is spun by a force rotation and dumby pivot centred both above and below. Any help would be grand!

Below is a video I put together with my experiments that shows the extent of my problems! Sorry about the quality - don't have great editing software or any capturing technology.

I've been pottering about making tracks for a while now and most of the stuff I've managed on my tracks I worked out by trial and error but this one has got me. The physics are just not behaving!

Any good suggestions gets a prize - I'll let you play it when its finished

You are trying to move a lot of weight with a single force rotation, try using one for the top, and one for the bottom.

Try increasing the spacing between the platforms, the collision on them isn't actually exact so they are beating the hell out of each other, maybe if you only power the first platform, the rest will spin with just a rotation hinge attached.

Not a bad track idea, and one that you should be able to get to work with a bit more trials and error.

Thanks for your response.

Each column already has a dummy pivot and (slow) force rotation on the top and also on the under side of the trampoline. I had already used this as a way to stabalize it but as you can see it still needs work.

My main concern was the varying speeds even when there is only one column. A further problem seems to be the amount of objects in the room. Once glued completely, one column alone fills over half the bar!

Might be forces into spacing out the columns and placing static ledges between them

I'll update this thread when I revisit this later coz there's clearly a lot to do!

Hi, maybe I can help you. I have a track with spinning columns. I think what made it work for me is to use some sort of
free rotation hinge at the bottom which helps keep the columns at its place. Then the force rotation object doesn't have to carry the weight of the rotating object. If you want you can play the track if that helps. gt is kawakka

Just a note for you. Irratic spinning is usually down to an off centre hinge/rotation.
It's pretty hard to get it spot on the centre, but once you do things should calm down a bit.
You can however use the off centre to your advantage if you need. In my last track "Boiling Point" I have a water wheel that has a force rotation that is slightly off centre so it looks like the weight of the water needs to build before it moves. Subtle but effective
