How do I access raw tile id data? about yati HOT 4 CLOSED

Access from where, from inside Godot?

Ah sorry - I should've been more specific! This is a simple collision map - one value for collide, one value for free-to-move.

Access from a C# script. I was hoping to just grab an int array containing the tile values.

I've since found GetUsedCellsById( ), which might work if I pass in the value for the collide tile, then pass in the coordinates of where I want to move to to see if there's a collide tile at that position int the returned array. Seems a bit long winded compared to a simple array lookup, but if it works, it works! :)

Looking at the docu for GetUsedCellsById() and the parameters the method expects I've some doubts if you really would get useful information for your purposes. I assume the source_id to pass is the atlas source id () not a tile id.

But I'm not a Godot programming guru and so that's only sort of my "feeling".

Concerning collisions I'd probably try to make use of tile collision rects.
Those are imported to Godot.

Your gut feeling was correct :(

However, I've found a solution - a bit hacky, but using GetCellAtlasCoords() I can test against the atlas cell containing the blocking tile, and build a simple map up that way:

private byte[,] CollisionMap = new byte[MapWidth, MapHeight];

private void InitCollisionMap()
{
        string mapStr = "";
        
        for (int y = 0; y < MapHeight; y++)
        {
	        for (int x = 0; x < MapWidth; x++)
	        {
		        CollisionMap[x, y] = (byte)((tm.GetCellAtlasCoords(0, new Vector2I(x, y)) == BlockingTile) ? 1 : 0);
		        mapStr += CollisionMap[x, y];
	        }
        
	        mapStr += '\n';
        }
        
        GD.Print( mapStr );
}

Thanks for your help :)
