Switch Statements

Switch-statements come with default case by default (heh). If the default case is never reached, be sure to remove it.

If the default case is an unexpected value, it is encouraged to log and return an error

BAD

switch (variable) 
{
    case 1:
        break;
    case 2:
        break;
    default:
        break;
}

GOOD

switch (variable) 
{
    case 1:
        break;
    case 2:
        break;
}

BETTER

switch (variable) 
{
    case 1:
        break;
    case 2:
        break;
    default:
        Debug.LogError("Unexpected value when...");
        return;
}
