Rare issues whit Physics

[Javier]

Hello.

I am having some problems, or I am doing things bad, whit the Physics in GameCore.

First, if I set a "UseRenderObject" Collision Type to a Object, the Collision seems to be at the center of the Word. If I move the object, the collisions are still placed at the center of the World. I have tested it whit a terrain and whit object whit the same result.  This also happend whit the "Object" Collision Type.


Another thing is whit the fantastic Physics Editor.
If I edit a Collision and change the Type to "RenderObject", when I close and edit the collission again its change automatically to "Object" Type.

FIrst question i don't know but second is that when you change the physics options you then have to go into object properties and save. All collision stuff is printed to the .opr. After you make changes you have to save that .opr or else it will go back to what it was....i think

No autosave? I will try it more today. Thanks

Well it was like that in alpha at least. That you had to manually save after changes. Let's hope it's just this small issue. I am at work and cannot try it now. Good luck

When you move an object the collision doesn't update with it but it is moving really. If you run the game, it will work.

To update it's position in the editor you can chose 'Test Physics', and you will see it change.

Thanks BigDaz.

I'm also having some physics problems.

 I can't seem to get any of the joint parameters to take hold. What's the process for limiting a hinge's rotational axis and adding friction or drag? My doors are spinning freely 360 degrees and not slowing down.

My sliding joints for desk drawers are jittery and seem to fly about. What's the process for smooth sliding drawers?

There are some issues with the auto-updating of the visible collision meshes in the editor viewport currently.  things aren't being reloaded properly.

You should not need to save through the properties panel at all now - when you close the physics edit panel (or select a different object) the changes are applied automatically.

The 'RenderObject -> object' bug has been fixed - you can apply render objects to your models properly now.  The work around fix for this is to use the traditional Object Properties editor to add the properties manually instead of through the physics editor.

Regarding joint damping, I know that ODE has some issues with damping, it's sort of a known issue that we're looking into - not sure what the fix is for that currently (unless you script in some 'reverse forces' to manually slow things down - this is what the vehicle script does)

Just a note, I've noticed that hitting "reload object" in the object properties panel seems to be a good fix for any of the other modules not updating, like the physics editor.

Would anybody be kind enough to explain getting a simple sliding joint to function between two objects? I can't get my objects to do anything but dance for me.
