# init(toAvoid:maxPredictionTime:) Creates a goal whose effect is to make an agent avoid colliding with the specified other agents, taking into account the other agents’ movement. ``` convenience init(toAvoid agents: [GKAgent], maxPredictionTime: TimeInterval) ``` ## Parameters `agents` The agents with which to avoid collisions. `maxPredictionTime` The amount of time during which to predict collisions. ## Return Value A new goal object. ## Discussion The `agents` array can safely include the agent(s) affected by the goal—an agent pursuing this goal will ignore itself in the array. Therefore, you can use a single goal created with this method to cause an entire group of agents to mutually avoid one another. The `maxPredictionTime` parameter controls how far in the future a predicted collision must be in order for the agent to take action to avoid it. For example, if this parameter has a low value, two agents speeding toward one another will not swerve or slow until a collision is imminent (and depending on the properties of those agents, they might not be able to move quickly enough to avoid colliding). If this parameter has a high value, the agents will change course leisurely, well before colliding. --- Copyright © 2026 Apple Inc.
