Physical response jitter on vertical path platform

Postby lverona » Fri Apr 27, 2012 9:11 am

When an actor lands on a moving platform, I make him child of that platform so that he moves along.
I also have a Physical Response. All of this works fine with a horizontally moving platform.

But when he is on a vertical one - the view jitters, up and down really quickly.
What am I missing in case of the vertical movement?

What code are you using for view movement, and for the collision? I can make it work using what you said in your post.

I get the same jittering. I wonder what it is.

And we can't solve either problem without having an example, or at least the code. I know said jittering can happen when dealing with physical response and parenting the view to the actor, but only in some cases.

I've been trying to get the actor collisions to work for a while now. Can I send you the file and you take a look?

Hey skydereign!

I solved the problem by going for Game A Gogo approach to collision using CollisionFree. This seems like a very good solution, at least at this moment of using GE for the fourth day )))

As long as you can understand the code used in that method, that is great. Though I usually prefer to find out what was going wrong, before switching methods up, but that is just me.

I also do, indeed. But when I read about the CollisionFree method, which would remove all the collision events one has to write, I decided it sounds like a better approach. If I would decide to go for PhysicalResponse method, I would definitely want to find out what the problem is!

As for the CollisionFree method, I spend the whole day studying the code until I understood every line ;)
