# EntityRadius entity,x_radius#[,y_radius#]

# Parameters

entity - entity handle x_radius# - x radius of entity's collision ellipsoid y_radius# (optional) - y radius of entity's collision ellipsoid. If omitted the x_radius# will be used for the y_radius#.

# Description

Sets the radius of an entity's collision ellipsoid. 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). See also: EntityBox, Collisions, EntityType.
