Game Development / Game Mechanics / [odejava] collision problems
|
on: 2005-03-31 09:00:57
|
I'm having a strange problem: I have a Body that has an attached GeomSphere. Prior to executing the following code, it can collide with any object without issues. After executing the following, which is supposed to swap out the GeomSphere with one of a different size, it can only collide with other Bodies. It can't, for example, collide with bodyless GeomBoxes. I've verified that the collisions are detected when I loop over the contact object. The problem is that no matter what flags I set on contact, there is no visible effect on the spheres. The sphere objects do start to rotate by some very tiny amount after the "collision," though. Also, I'm using the current cvs version of odejava. 1

I just tried that, and it seems to fix most of the problems. However, now I'm getting native exceptions (with much less frequency, though) in really strange places, like ntdll.dll. For example: 1

They don't specifically refer to odejava anywhere, but they don't happen without it, so I'm at a loss as to what the real problem is. Could I have miscompiled odejava? |

Game Development / Game Mechanics / Internal errors and native crashes..

In order to simulate an expanding object, I am swapping out the geoms of a body fairly quickly. The effect looks good, but it's causing a variety of internal errors and crashes. This is how I'm trying to do it: 1

this.sim_body.addGeom(geo);

It causes the following "ODE Internal Error 2" message: Bad argument(s) (ode/src/collision_space.cpp:182) and when that doesn't happen, I get a message like this: 1

It seems to be fixed now. I had to manually set an inertial tensor and center of mass with setMassParameters. I also changed the ordering around a bit. Not sure why this was necessary though.
Thanks for the help though :P

Game Development / Game Mechanics / rotating composite bodies

Hi - How do you rotate composite bodies? I have one that is made up of a number of GeomTransforms, and I'm trying to rotate it around its Z-axis at a particular angular velocity, but I'm having no luck.
I've tried using the setAngularVel() method on the body and I've also tried using AMotors, but the body just doesn't rotate.

Add your game by posting it in the WIP section,
or publish it in Showcase.
The first screenshot will be displayed as a thumbnail.
