Bullet Sim not found

[BogusCurry]

Hello ;D

I have enabled the Bullet Sim Engine in the physic.ini, after the start from my grid comes ...

Okt 08 07:00:05 - [Physics]: Couldn't find physics engine: BulletSim Okt 08 07:00:05 - [APPLICATION]: APPLICATION EXCEPTION DETECTED Exception: System.ArgumentException: couldn't find physics engine: BulletSim at WhiteCore.Modules.Startup.PhysicsPluginManager.GetPhysicsScene (System.String physEngineName, System.String meshEngineName, IConfigSource config, IScene scene) [0x00000] in :0 at WhiteCore.Modules.Startup.PhysicsInitializer.Initialise (IScene scene, IConfigSource source, ISimulationBase simBase) [0x00000] in :0 at WhiteCore.Region.SceneManager.StartModules (IScene scene) [0x00000] in :0 at WhiteCore.Region.SceneManager.StartRegion (ISimulationDataStore simData, WhiteCore.Framework.SceneInfo.RegionInfo regionInfo) [0x00000] in :0 at WhiteCore.Region.SceneManager.StartRegions (System.Boolean& newRegion) [0x00000] in :0 at WhiteCore.Region.SceneManager.PostStart () [0x00000] in :0 at WhiteCore.Simulation.Base.SimulationBase.StartModules () [0x00000] in :0 at WhiteCore.Simulation.Base.SimulationBase.Startup () [0x00000] in :0 at WhiteCore.Simulation.Base.BaseApplication.Startup (IConfigSource originalConfigSource, IConfigSource configSource, ISimulationBase simBase, System.String[] cmdParameters) [0x00000] in :0 Application is terminating: False

Is the engine not in WCS ?

Greetings

Hi Bogus, This is certainly unusual as the BulletSim physics is certainly part of the distribution. However, the engine is broken in the current version even though it should load etc. You will need to grab the Dev version to check out the changes that we are making to upgrade and get Bullet working correctly. From all reports from what I have seen and a couple of testers have observed, the upgrades are working really well with fast and smooth operation. There are still a couple of issues still to be sorted out though.

I would suggest holding off for a little while as I have another set of updates from |-Fine-|, who is working on these updates, to incorporate into the Dev code. This should be done by the weekend.

Hi greythane ;D I had grab the new version from github ;D Ok, I can wait ..

[fine77]

couldn't find engine means you have to copy 2 files out of the source tree:

1. "$WhiteCore_installation_directory/WhiteCore/Physics/BulletSPlugin/bin/WhiteCore.Physics.BulletSPlugin.dll" and the *.pdb file to "$WhiteCore_installation_directory/WhiteCoreSim/bin/Physics/"
2. "$WhiteCore_installation_directory/WhiteCore/Physics/ConvexDecompositionDotNet/bin/WhiteCore.Physics.ConvexDecompositionDotNet.dll" and the *.pdb file to "$WhiteCore_installation_directory/WhiteCoreSim/bin/Physics/"

Where $WhiteCore_installation_directory is the path to your WhiteCore installation.

have fun

[BogusCurry]

ahh ok .. thanks fine77 ;D

[greythane]

BogusCurry, I have just implemented and pushed through a heap of updates for BulletSim that Fine did for us. These correct many problems with Bullet physics and some basic checks show very pleasing results in frame rate etc. If you are able, could you grab the latest Dev (master) code and give Bulet a try again and see how it performs.

[fine77]

great!! its there now. i saw it now

[BogusCurry]

Thanks greythane ;D I will test this ;D

[BogusCurry]

Ok, I have clone the last dev version from repo, the problem is not fix. I have mono 4.0.5.1 under Linux Mint 17.2. So I not know, make what is wrong

Here the message ..

Be sure to follow the instructions from @fine77 to get Bullet setup

[emperorstarfinder]

Try downloading a zip or tar gz copy of the repository just in case your not getting some of the necessary files in the bin folder. Sometimes files that are needed will not get pulled through git.

[greythane]

Hmmm.. I will recheck the prebuild stuff to make sure that the dlls are being compiled to the correct directory.

[greythane]

Bogus, I have pushed through some corrections to the prebuild configurations that will correct the output (save) paths for the missing Bullet dll's.

On *nix you should be able to update and then run ' ./autobuild.sh ' and all should be 'good to go'

Hello ;D Ok, bug is fixed ;D We can closed this ;D
