Matter.Body.setStatic() - setting to false after already true removes body

[dvulanov]

I would like to be able to toggle a body between static and non-static, but it looks like once a body is set to static un-setting it messes something up and the body disappears from the render view.

Should it be possible to use setStatic in this manner? I'm using latest build (2015-12-23).

Thanks!

Ok, looks like resetting the body's mass to something non-static (i.e. non-infinity) does the trick. This allows me to use Matter.Body.setStatic() in a way where I can toggle a body's static property.

thanks,
Dan

It's a known limitation that you can't unset static once it's been set. The reason is that it requires certain properties to be set to Infinity (e.g. mass) which means the old value is lost.

A possible fix is to add some sort of property cache to bodies so they can be restored, but this is currently a low priority.

If you need this, you should be able to look at Body.setStatic and do something similar for your own project though.

Perfect, will do.

Was this ever solved?

Not implemented yet but in the meantime you can implement your own based on my previous comment, I'll look at this again soon.

you can use eventListener to change static status with Body.setStatic(obj.body, false/true);
