changing material properties in runtime #257

Closed speculees closed 8 years ago

speculees commented 8 years ago

Hello, nice work with Physijs. I was wondering is it possible to change material properties in runtime, such as friction, mass and restitution. I tried changing the material object attribute values, and creating a new object. Everything looks okay in inspector. The object attributes have correct values, however the Physijs seems to ignore them. Also, I noticed that gravity has strange behavior. Vector(0,0,0) works as expected, but when y is negative the amount makes no difference. It can be -9.81 or -9810000... I will set up example soon.

Gravity works perfectly for me.

@peterjwest , you are right. It does work. I noticed that when I switched to a better PC. It was just difficult to notice such subtle changes on low end hardware. Thanks for the reply.

Changing the whole physics mesh instead of material worked for me. First I remove the meshes from scene and load them again with different material attributes, Marking this as closed.
