Physics

-

Reproduction steps:
1. Open the project inside "case_1108989-AddExplosionForce_Problem.zip"
2. Open and Play "TestRigidbodyExplosiveForce2" scene

Expected: The circle will follow the predicted blue trajectory line
Actual: The circle flew not according to the trajectory line

Reproduces on: 2017.4.20f2, 2018.3.6f1, 2019.1.0b4, 2019.2.0a6

Note: Velocity relative change after explosion can be seen in "Cube" GameObject's "RigidbodyAddExplosion" component

    Resolution Note (fix version 2019.1):

    The issue was due to documentation being out of date. The documentation previously mentioned, that the explosion was towards the center of body. However, in reality it was towards the point on the surface of the body that is closest to the explosion location. The documentation was updated to reflect this.
