Class

GKAgent3D

An agent that operates in a three-dimensional space.

Overview

Agents are game entities that move according to realistic constraints and whose behavior is determined by goals that motivate movement. The general functionality of an agent is defined by the abstract superclass GKAgent; however, you use instances of the GKAgent3D class to implement agent-based gameplay in a 3D game.

To learn more about using goals and agents, see Agents, Goals, and Behaviors in GameplayKit Programming Guide.

Topics

Managing an Agent’s Position and Orientation

var position: vector_float3

The current position of the agent in 3D space.

var rotation: matrix_float3x3

The orientation of the agent in 3D space.

Running the Agent Simulation

func update(deltaTime: TimeInterval)

Causes the agent to evaluate its goals and update its position, rotation, and velocity accordingly.

var velocity: vector_float3

The current velocity of the agent in 3D space.
