Properties and methods
Once you have created your instance, you can access these Read-Only properties:
ws.grid
Returns the puzzle's grid
[
["S", "Š", "M", "Y", "W", "X"],
["E", "C", "K", "M", "O", "G"],
["A", "R", "Z", "O", "R", "A"],
["R", "Ê", "N", "F", "D", "I"],
["C", "P", "I", "Y", "Q", "A"],
["H", "E", "L", "L", "O", "I"]
]
ws.words
Returns the words that were successfully inserted in the grid:
[
{
word: "word",
clean: "WORD",
path: [
{ x: 4, y: 0 }, // W
{ x: 4, y: 1 }, // O
{ x: 4, y: 2 }, // R
{ x: 4, y: 3 } // D
]
},
{
word: "crêpe",
clean: "CRÊPE",
path: [
{ x: 1, y: 1 }, // C
{ x: 1, y: 2 }, // R
{ x: 1, y: 3 }, // Ê
{ x: 1, y: 4 }, // P
{ x: 1, y: 5 } // E
]
}
/* ... */
];
ws.forbiddenWordsIncluded
Returns an Array of forbidden words which were inserted into the grid because no other solution was found after maxRetries
:
["CRAP"]
You can also use these methods:
ws.dump()
Returns an Object representing the state of the puzzle. This can be useful if you want to save a game and reuse it later using ws.load(backup)
.
ws.load(backup)
Loads a game from an Object of a previous dump.
const ws1 = new WordSearch(/* ... */);
const backup = ws1.dump();
const ws2 = new WordSearch().load(backup);
// ws2 is now a copy of ws1
ws.toString()
Returns a String representing the grid of the puzzle. This can be useful if you want to print it to the console.
S Š M Y W X
E C K M O G
A R Z O R A
R Ê N F D I
C P I Y Q A
H E L L O I
ws.read(start, end)
Reads the letters from start
to end
positions and returns the String it forms. This can be useful to check what letters a user highlighted.
ws.read({ x: 1, y: 0 }, { x: 5, y: 4 }); // "ŠKODA"
