我有GKEntity
一个GKAgent2D
组件。它的行为GKGoal
是toWander:
和toStayOnPath:maxPredictionTime:
。实体在场景中不断游荡;但是,我希望它停止徘徊一段时间。例如,如果实体是一只四处游荡的羊,我希望它定期停下来吃东西,并在延迟之后再次开始游荡。
更新:
在实体中:
addComponent(MoveIdleComponent(maxSpeed: 60, maxAcceleration: 6, radius: Float(node.texture!.size().width * 0.3), entityManager: entityManager))
移动空闲组件
class MoveIdleComponent : GKAgent2D, GKAgentDelegate {
let entityManager: EntityManager
init(maxSpeed: Float, maxAcceleration: Float, radius: Float, entityManager: EntityManager) {
self.entityManager = entityManager
super.init()
delegate = self
self.maxSpeed = maxSpeed
self.maxAcceleration = maxAcceleration
self.radius = radius
print(self.mass)
self.mass = 0.01
}
func agentWillUpdate(agent: GKAgent) {
guard let spriteComponent = entity?.componentForClass(SpriteComponent.self) else {
return
}
self.position = float2(spriteComponent.node.position)
}
func agentDidUpdate(agent: GKAgent) {
guard let spriteComponent = entity?.componentForClass(SpriteComponent.self) else {
return
}
spriteComponent.node.position = CGPoint(position)
}
override func updateWithDeltaTime(seconds: NSTimeInterval) {
super.updateWithDeltaTime(seconds)
behavior = WanderBehavoir(targetSpeed: maxSpeed)
}
}
流浪行为:
class WanderBehavoir: GKBehavior {
init(targetSpeed: Float) {
super.init()
if targetSpeed > 0 {
setWeight(0.5, forGoal: GKGoal(toWander: targetSpeed))
}
}
}
我怎样才能做到这一点?
