RaycastVisualization Save

This asset allows users to view raycasts as the user fires them.

Supports both the 2D and 3D api.

Installation

Using Unity Package Manager

1. Open the Package Manager from Window/Package Manager
2. Click the '+' button in the top-left of the window
3. Click 'Add package from git URL'
4. Provide the URL of this git repository: https://github.com/nomnomab/RaycastVisualization.git
5. Click the 'add' button

Usage

To get a visual to show up for a physics call simply do the following:

For 3D:

• Replace Physics. with VisualPhysics..

For 2D:

• Replace Physics2D. with VisualPhysics2D..
• Some 2D functions rely more on a 3D perspective in the editor depending on the orientation of the casts.

// Example
void SomeFunction() {
    if (VisualPhysics.Raycast(position, direction)) {
        Debug.Log("Hit!");
    }
}

API Switching:

You can also use a trick to automatically swap between the two APIs (useful for when you want to use the visual API in the editor, but the normal API in builds):

• Using VisualPhysics in a build will use the normal Physics API, however the method call may not be inlined depending on the compiler's mood.

#if UNITY_EDITOR
using Physics = Nomnom.RaycastVisualization.VisualPhysics;
#else
using Physics = UnityEngine.Physics;
#endif

void SomeFunction() {
    if (Physics.Raycast(position, direction)) {
        Debug.Log("Hit!");
    }
}

Defining a Visual's Lifetime:

Using VisualLifetime.Create(seconds) you can define how long a cast will display for:

// will display the raycast for a second, rather than a single frame
using (VisualLifetime.Create(1f)) {
    if (VisualPhysics.Raycast(position, direction)) {
        Debug.Log("Hit");
    }
}
