Black screen

A black screen is an error that can happen when modifying Sandboxels. It usually has to do with something being missing or undefined, particularly

• something trying to make a nonexistent element, or
• something trying to reference a nonexistent pixel.

A black screen intentionally created by editing Sand.

Typically, the screen will appear black regardless of whatever pixels exist. Depending on the issue, pausing the screen may allow the pixels to render by stopping the erroneous ticking. If, however, the issue is that a pixel of a nonexistent element has somehow been created, the resulting error will be in the rendering code and nothing can render at all.

In any case, the simulation will fail to tick, and it will be frozen until the offending pixel(s) are deleted.
