Preload more data

It would make things easier if more data is analyzed (like in tile.js) before starting the draw loop.

When creating the Grid, save the x and y positions as well as the coordinates (x1, x2, y1, y2 for example) this will eliminate the need for 2 loops as well as allowing for clicking on a specific Cell.

To each Cell in the Grid I added an up, down, left & right value to check for valid values, this saves time when comparing.
To each Tile in the TileSet I added a value to disallow for self-connecting and I filter those out in the Tile.analyse() function

my code is at: https://github.com/Fietsje/Wave-Function-Collapse

I really like seeing this project in action...

先閱讀 tile.js，追蹤在繪製迴圈之前如何使用 Grid、Cell、TileSet 和 Tile.analyse()；將提議的方法與連結的 Wave-Function-Collapse 實作進行比較。完成的標準應是：在繪製之前準備好所需的位置、座標、鄰居值和自我連接篩選，同時允許點擊特定的 Cell，並減少冗餘迴圈。
