How to add prefabs to controllers in Unity VR

Unity is a platform that provides us with the necessary tools to develop games in 2D and 3D. It also enables us to create virtual reality (VR) and augmented reality (AR) applications. In this Answer, we will learn how to add prefabs to a controller in Unity VR. The three stages that we will follow are:

• Importing the prefab.

• Attaching the prefab.

• Adjusting the prefab.

Importing the prefab

We need an object for which we want to have the prefab. Some considerations while importing the prefab are:

• We create an object or import it from the Unity Asset Store. It can be any object, such as a tool, weapon, or a car.

• We need to customize that imported object according to the game's scenario ( like adding material or changing the script).

• Once you are done with the requirements of an object, we select it in the project view or Unity Editor Hierarchy.

Attaching the prefab

The main points to focus on while attaching the prefab are mentioned below:

• Ensure that the VR controller and game object are available in the scene. Select the VR controller to which you want to attach the prefab.

• Drag and drop the prefab object from the prefab folder onto the VR controller game object present in the hierarchy.

• This results in making a prefab a child of a VR controller.

Adjusting the prefab

After attaching the prefab, it is important to adjust the prefab according to your requirements. Make sure to keep the following aspects in mind:

• Sometimes prefab requires proper interaction with the VR controller through input buttons, considering that we have to add appropriate event handlers and scripts to the prefab.

• After this, we need to test both the controller and the prefab if they are working and ensure that they behave exactly as expected.

Following the above-mentioned steps, we will be able to attach the prefab to the controller successfully.

Conclusion

In this Answer, we learned how to attach the prefab to the VR controller in the Unity platform. We also discussed how to adjust the prefab according to the requirements of the controller so that the process runs smoothly.
