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

Supports both the 2D and 3D api.

Installation

Using Unity Package Manager

Open the Package Manager from Window/Package Manager
Click the '+' button in the top-left of the window
Click 'Add package from git URL'
Provide the URL of this git repository: https://github.com/nomnomab/RaycastVisualization.git
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");
    }
}
