Hi I am begining a new project whereby the player can see a map but can only see the geographical info. As the game continues the players influence increases and so they can see more things on the map e.g. cities armies etc.
I realise I could make each individual item an image and it appears as the influence gets bigger, but ideally i would like to do it with two images. 1 which is the background and has everything on it and then a top image that has no objects on it.
Then like the flashlight example the sphere of influence would show the sprite below rather than the top object or create a hole in the top sprite. I would ideally like to do it this way as it will be a lot easier to build the game with a simple set of events like this than creating every city and item on the map as a seperate object.
Any thoughts on how this could be achieved?
