Description
This example implements a simple pen which can make up to 20 synced, colored lines and an eraser which is highlights and deletes lines drawn by the local player.
By putting a VRC Player Object component on the SimplePenSystem, it is automatically spawned for each player in the world (and removed when they leave). All synced properties of the pen system are automatically saved and loaded - like its position and the points and colors of each line.
How to Use This Example
Play the scene, pick up the pen, and tap Use without moving the pen much to cycle through the available colors. Hold Use and move the pen to make lines in 3D space, release Use to finish the line.
Drop the pen and pick up the eraser, then stick the eraser directly into any of your lines. Known Issue: In ClientSim, this does not highlight the line - it works in the VRChat Client.
Press Use to delete the selected line - this adds it back to your collection of 20 lines.
Stop the scene and then restart it to see your lines restored!
Udon Pen

- If you want more lines available per pen, just duplicate some of the existing lines! No other changes needed
- You can make changes per-line if you want, like setting different widths or materials
Roadmap
- Respawn the pen whenever it’s more than X units away from you
- New color picker, one where you hold a button to show a palette, then move to the color you want to use
- Refactor to allow infinite lines
