The application wait the file to load, but FileSystem::update always suspend the thread because filesystem_cache small

Related to this post. Actual problem is that Object::getCollision() is still a blocking call, which has to be "guarded" by Object::HasRender() at various code sections.

 

if( object->hasRender() 
{ 
   object->getCollision(); 
   ...
}

thanks, glad it has been fixed

It has been fixed for RenderScene::getIntersection(), but most probably NOT for some other calling code parts

 

• World::getIntersection()
  
• Physics::getIntersection()
  
• PhysicsScene::getIntersection()
  
• ...
  

 

so centralizing this test in Object::getCollision() might be a good idea.

Then I guess thats how I sent the 'Samples' program in the Physics section of the evaluation kit into an infinite loop? :lol:

 

I was driving the car around, running over the ragdolls, then I jumped off one of the ramps and hit the ground pretty hard (a ground already littered with ragdolls). The wheels appeared to have literally 'blown off' the car, the body of the car was stuck in some weird orientation, and the sample froze. Appears to be burning 100% of one CPU core. Thread deadlock maybe? If there's anything I can provide that might help you guys out, let me know what I need to do.

 

The engine is performing very well so far, this is the first issue I've seen with it thus far--and I've gone through nearly all of the demos.
