Combining WareHouseModel and Experiments

Question

I am trying to run experiments using the WarehouseRenderer and AgvRenderer from AgvExample.

I get the following exception:

Exception in thread "main" java.lang.IllegalArgumentException: Could not resolve dependency for implementations of interface com.github.rinde.rinsim.core.model.road.CollisionGraphRoadModel, as requested by WarehouseRenderer.builder().

This error indicates that there is a renderer attached to the simulator that expects a model of type CollisionGraphRoadModel. A renderer can only function correctly if there is a corresponding model that contains the data that needs to be rendered.

In AgvExample the following code (see lines 86-90) is used to add the required model:

.addModel(
  RoadModelBuilders.dynamicGraph(GraphCreator.createSimpleGraph())
    .withCollisionAvoidance()
    .withDistanceUnit(SI.METER)
    .withVehicleLength(VEHICLE_LENGTH))

You can add similar code if you want to use the WarehouseRenderer in your code.

Can you provide more context as to why this error is occurring? Does the AgvExample not work for you out of the box? — rinde, May 30 '19 at 02:30
