Sets the radius of an entity's collision ellipsoid.
|
|
|
|
<br />
|
|
|
|
<br />
|
|
An entity radius should be set for all entities involved in ellipsoidal collisions, which is all source entities (as collisions are always ellipsoid-to-something), and whatever destination entities are involved in ellipsoid-to-ellipsoid collisions (collision method No.1).
