How to use

Extend base engine

before you use CEPathFind, you shoud provide an pathfind engine with overrde this class CEPathFindBasic.cs


    //Get an tile property
    //you can check A start path find wiki for more info about score.
    override public void GetTileProperty (int _tileX, int _tileY, 
                                         CEPathFindNode _star, CEPathFindNode _end, 
                                         out bool _isWalkable, out int _score)
    {
        _isWalkable = true;
        _score = 1;
    }


    override public bool isTileWalkable (int _tileX, int _tileY)
    {
        return true;
    }


    override public TILE_SERACH_TYPE GetTileSerachType ()
    {
        return TILE_SERACH_TYPE.EIGHT_DIRECTION_FIX_CORNER;
    }

Call pathfind

there is two way to use it.

  • Immediate return
CEPathFindResult result = CEPathFind.FindPath (starTileX, starTileY, endTileX, endTileY, findEngine);

Debug.Log(result.toString());

in this way,the function will return the result immediately.


  • Async call back

CEPathFind.FindPath (starTileX, starTileY, endTileX, endTileY, findEngine,ShowPath);

private void ShowPath (CEPathFindResult _result)
{
    Debug.Log(result.toString());
}

in this way ,you need provide an callback(Action<(CEPathFindResult >),when the path find finish ,it will call back.

Attaction: if you use this way, you should attach CEPathFind.cs to an gameObject.

also you can change the each tick search node num in CEPathFindAgent.cs

private const int EACH_TICK_SEARCH_NODE_NUM = 50;
