## Utility class for field parameters and connected functions

class_name FieldParams

## Tile size
const TILE : Vector2 = Vector2(50,60)
## Rows count of field
const ROWS : int = 5
## Columns count of field
const COLUMNS : int = 9

## Field rectangle. Origin is set in-game
static var field_rect : Rect2 = Rect2(0,0,COLUMNS*TILE.x,ROWS*TILE.y)

## Converts vector position into int index. Hash somewhat
static func indexify(position : Vector2) -> int:
	var tiled_position = (position/TILE).floor()
	return int(tiled_position.x) + int(tiled_position.y * COLUMNS)

static func deindexify(index : int) -> Vector2:
	return Vector2(index % COLUMNS  * TILE.x, index / COLUMNS * TILE.y)
