Runtime character object. This object usually represents the player or a humanoid AI. It uses a single rigid body, usually with a capsule shape to simulate movement and collision for the character. The character is a keyframed object, the application controls it by setting the velocity.

) |
Constructor
inSettings | The settings for the character |
inPosition | Initial position for the character |

inUserData | Application specific value |
inSystem | Physics system that this character will be added to later |
|

Destructor.
void Character::Activate | ( | bool | inLockBodies = true | ) |

Get all contacts for the character at a particular location.
inPosition | Position to test. |
inRotation | Rotation at which to test the shape. |
inMovementDirection | A hint in which direction the character is moving, will be used to calculate a proper normal. |
inMaxSeparationDistance | How much distance around the character you want to report contacts in (can be 0 to match the character exactly). |
inShape | Shape to test collision with. |
inBaseOffset | All hit results will be returned relative to this offset, can be zero to get results in world position, but when you're testing far from the origin you get better precision by picking a position that's closer e.g. GetPosition() since floats are most accurate near the origin |
