In Unity, you can use the Camera.RenderToCubemap() method to check if an object or scene is in view of the camera. The method returns a boolean value which represents whether the object is in view. This guide explains how to check if an object is in view using this method.
Prerequisites
Before you can use the Camera.RenderToCubemap() method in Unity, there are a few prerequisites that need to be met:
- Unity 4.2 or above
- Unity Pro
- The object must have a Mesh Collider component
Checking if an Object is In View
To check if an object is in view in Unity, follow these steps:
- Add a Mesh Collider component to the object.
- In the script that checks whether the object is in view, add the following code:
// Check if the object is in view
bool isInView = Camera.main.RenderToCubemap(cubeMap, 0);
This code checks if the specified camera renders the stage to a cubemap and returns true if it does. If the object is not in view, it will return false.
- If the return value is
true, the object is in view.
