Revision history [back]

Updating the code to:

    grid_x = (transform.getOrigin().x() - (int)map.info.origin.position.x) / map.info.resolution;
    grid_y = (transform.getOrigin().y() - (int)map.info.origin.position.y) / map.info.resolution;

And as per yigit's suggestion

currentPoint = map.data[grid_x * mapWidth + grid_y];

Fixed the problem. Turns out my origins weren't 0,0,0 like I thought.

Thanks.
