Class AILerp Extends VersionedMonoBehaviour, IAstarAI
Linearly interpolating movement script.
This movement script will follow the path exactly, it uses linear interpolation to move between the waypoints in the path. This is desirable for some types of games. It also works in 2D.
See
You can see an example of this script in action in the example scene called Example15_2D.
Configuration
Recommended setup for movement along connections
This depends on what type of movement you are aiming for. If you are aiming for movement where the unit follows the path exactly and move only along the graph connections on a grid/point graph. I recommend that you adjust the StartEndModifier on the Seeker component: set the 'Start Point Snapping' field to 'NodeConnection' and the 'End Point Snapping' field to 'SnapToNode'.
Recommended setup for smooth movement
If you on the other hand want smoother movement I recommend setting 'Start Point Snapping' and 'End Point Snapping' to 'ClosestOnNode' and to add the Simple Smooth Modifier to the GameObject as well. Alternatively you can use the Funnel Modifier which works better on navmesh/recast graphs or the RaycastModifier.
You should not combine the Simple Smooth Modifier or the Funnel Modifier with the NodeConnection snapping mode. This may lead to very odd behavior.
You may also want to tweak the rotationSpeed.
Public Methods
