# init(toSeparateFrom:maxDistance:maxAngle:) Creates a goal whose effect is to make an agent maintain the specified distance from other agents in a specified group. ``` convenience init(toSeparateFrom agents: [GKAgent], maxDistance: Float, maxAngle: Float) ``` ## Parameters `agents` The agents from whom to maintain distance. `maxDistance` The maximum distance from other agents required for this goal to take effect. `maxAngle` The maximum angle, in radians, between an affected agent’s velocity and the direction toward the other agents required for this goal to take effect. ## 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. Changing the `maxDistance` parameter determines the minimum distance between agents in the group. Changing the `maxAngle` parameter determines how tightly an agent will turn to maintain separation from the group. You can combine separation, alignment, and cohesion goals to produce “flocking” behaviors in which a group of agents move together. --- Copyright © 2026 Apple Inc.
