Console Access

The Harriet game engine has a hidden operational console. This can assist enthusiasts and active developers by spawning items and debugging existing application specific use cases. The specific key to access a console instance is via the TILDE key also known as a swung dash.

It has the ASCII code: 126. For Microsoft virtual key codes, this is the VK_OEM_3 key (0xBF). On US qwerty keyboards, its typically located to the top left of your keyboard's layout below the ESC key.

This key can be toggled to switch the visibility state of the console. Since the console is the last entity to be rendered in 2d space above the 3d scene, all inputs and key strokes will be directed to the console until its visibility has been set false.
