Dear all, first off the problem I have is not caused by a bug with Piccolo2d. It is related to a game that I am writing using Piccolo 2d.
Let me explain: 1. I have a map board made up of hexagons - each hexagon being a PPath with additional child PPaths for the terrain within the hexagon. 2. I need to verify a Line Of Sight between hexagons. To do this I am taking the centre point of the from and to hexagons and using a line calculation algorithm picking the nodes in between. This works fine with PPath nodes as the picking works a dream. The problem comes when I add an image, for a building. The picking works fine if the PImage is rectangular and is not rotated. However I do have non rectangular buildings which are rotated. This means that the picking will pick the building PImage when there is no building at that actual point. I have implemented a halfway solution whereby I create a BufferedImage of the view and trace a line from start to end point. As the building images are transparent me getPixel function checks for non transparent colours and reports an obstacle. - This sort of works ok but has been a right muddle to implement due to transposing the start and end points on the screen to the BufferedImage. - Also this only works when checking the LOS of the on screen visible portion of the map. What I was wondering was .... has anyone got any ideas/ suggestions? I have thought of creating a PPath around the building and using that when picking making the image layer invisible at the moment of picking - Are there any other ideas??
