Creating a drawing system

In this section, we’ll be focusing on creating a drawing system that incorporates two core components: a canvas that can be drawn on and a marker that can be used for drawing. These two objects work together to create the drawing experience. Individually, they are just objects that you can interact with. You can expand on this system by modifying the canvas to cover a larger area, allowing you to draw on a larger surface instead of the predefined size we initially create.

To create a drawing canvas (Figure 12.7), go through the following steps:

1. Create a new plane.
2. Name it Whiteboard.
3. Set the X position to 3.6, the Y position to 2.4, and the Z position to -0.4.
4. Set the X rotation to 90, the Y rotation to 90, and the Z rotation to 90.
5. Set the X scale to 0.3, leave the Y scale at 1, and set the Z scale to 0.3.
6. Create a new C# script, name it WhiteboardController, and add it to the Whiteboard GO.
7. Add the following namespace...
