Accessing GameObjects and Scripts in your Scene

The Experiment, Block, and Trialclasses reside in the voids of C# and don’t really interact with the unity system at all. For this reason, you need to create a link between your unity project and your custom trial script.

To do this, you need to create references to them in your custom ExperimentRunner class. For example:

public GameObject GameObjectThatMoves;  

Then, in your custom Trialscript you can reference your custom ExperimentRunner using the following

MyCustomExperimentRunner myRunner = (MyCustomExperimentRunner)Runner;

This line converts the generic ExperimentRunnerthat is stored in the Runner field into your customized version of the class.

Then you can access a GameObject, or other public unity field referenced within the customized ExperimentRunner class with:

GameObject gameObjectThatMoves = myRunner.GameObjectThatMoves;

This allows you to use your ExperimentRunner object as a container to drag and drop references to GameObjects and other things in your unity scene that need to be controlled or accessed during your experiment.
