Description

Creates a window with a given ID and placement/size parameters. Windows are used to show dialog, present choices and so on, each of which reference the window's ID to insert text. This command only initializes a window ID, but does not present itself until a dialog command is issued on it.

Adjustments are made for windows that are either too close an edge, or the width / height is too big for the screen. Eg:

// Adjust window position if too close to an edge
const MIN_WINDOW_DISTANCE = 8 // Looks about right
if (x < MIN_WINDOW_DISTANCE) { dialog.x = MIN_WINDOW_DISTANCE }
if (y < MIN_WINDOW_DISTANCE) { dialog.y = MIN_WINDOW_DISTANCE }
if (x + w + MIN_WINDOW_DISTANCE > GAME_WIDTH) { dialog.x = GAME_WIDTH - w - MIN_WINDOW_DISTANCE }
if (y + h + MIN_WINDOW_DISTANCE > GAME_HEIGHT) { dialog.y = GAME_HEIGHT - h - MIN_WINDOW_DISTANCE }
