Physics Worker

[JBP]

Hello, can anyone tell me if the current implementation of the Physics engines (oimo, cannon) support Web Worker or its a single thread implementation ?

It's usually not worth running your physics in a separate Web Worker if you need to access the state of the world each frame, as reading/transferring data from the worker thread is costly and doing it each frame might be slow.

Yes since version 2.1 Workers is supported for the Physics engines (oimo and cannon)  :

To enable it to do:

scene.workerCollisions = true;

SetTimeStep 1/10 on phone with WebView Works smooth as 1/50 on desktop !!! Accuracy of physics work same. I verified this on My Project Perplexus. I have WebView for Android perplexus Project and with 1/10 It Works brilliant. On desktop It Works as fast as Real Perplexus If you ever try this Game. Try experiment on different devices with setTimeStep 1/10 or 1/5 for slower devices.

Hello, but this if for the build in collisions right ?
I asking for the oimo or cannon plug-in is the "world.step()" function called inside a Worker ?

Here is example of setTimeStep for physics. I did also as Dad72 say. But default 1/50 Works slow. The Real speed was when I add slider gui setings for setTimeStep. SetTimeStep is realy qul staff for slow phones WebView beleave me. If you dont try it
