Slick2D: getTileProperty returns true when it shouldn't

Question

I'm trying to implement some collision detection to a test game i've been making. I've used TiledMap to create the map and set a property on one of the tiles to blocked=true This tile is then drawn on layer 0.

I then check to see if the tile exists in the direction the player is moving, using the following code

if (input.isKeyDown(Input.KEY_DOWN)) {
    sprite = down;
    sprite.update(delta);
    int tileID = map.map.getTileId((int) x / map.map.getTileWidth(), (int) y / map.map.getTileHeight() + 1, 0);
    String value = map.map.getTileProperty(tileID, "blocked", "false");
    if (value.equals("true")) {
        y += delta * 0.1f;
        System.out.println("Tile ID: " + (int) (x / map.map.getTileWidth()) + ", " + (int) (y / map.map.getTileHeight() + 1) + " Try to walk down. Tile value below the player is:" + value);
    }

}

This is repeated for each direction.

The problem I'm running into is it's picking up the blocked property for incorrect tiles You can understand better with this video . The yellow tiles are the collision/blocked tiles.

Answer 1

I think you have this issue because you update the graphics outside your if statement

Try to move the ones below inside the if :

sprite = down; 
sprite.update(delta);

However I suppose one of these put the face of the sprite down and therefore should not be inside.
