[Navigation]Navigation初探[2]

在烘焙完了navMesh之后,就可以为放置在navmesh上的物体进行寻路了.

NavigationMeshAgent是所有需要导航的物体需要添加的控件.通过对Destination的设定可以让其物体自动移动.自动移动时,会改变其velocity.

当然,也可以通过CalculatePath()函数来获取计算出的路径而不进行移动操作.

 

Property:	Function:
Radius	Radius around the agent within which obstacles should not pass.
Speed	Maximum movement speed (in world units per second).
Acceleration	Maximum acceleration (in world units per second squared).
Angular Speed	Maximum speed of rotation (degrees per second).
Stopping distance	Minimum distance from the target within which the agent can stop.
Auto Traverse OffMesh Link	Should off-mesh links be crossed automatically without intervention from a script?
Auto Repath	Should a new path be calculated if the current one becomes obstructed or invalid?
Auto Braking	Should the agent automatically slow down as it approaches the target point?
Height	The height clearance the agent needs to pass below an obstacle overhead.
Base offset	Height difference between the anchor point of the GameObject and the centre point of the agent’s cylinder.
Obstacle Avoidance Type	An approximate quality level for obstacle avoidance.
Avoidance Priority	Agents of lower priority will be ignored by this agent when performing avoidance. The value should be in the range 0..99 where lower numbers indicate higher priority.
NavMesh Walkable	Specifies the Navmesh layers that the agent can traverse.

图片中的Acceleration表示的是加速度,表示每秒速度的最大变化量. 但除此之外,这个值还表示了物体转弯儿时的最大加速度,当此值较小时,转弯弧度会比较大,较大时,转弯弧度会很小.

Angular Speed表示的物体自身旋转的速度,即物体运动方向改变时,物体朝向的变化速度.
