2D Map Destruction

Hello Folks!

I'm wondering about the best way to destroy some points of a 2D map, just like Worms !
After playing worms on Android for a while, I noticed that the map was builded on runtime.

Someone know a good way to make something like it ?

Regards

Actually i would think on something based on shape and mask with collision and recalculate bounds , but on the second post there a lot of cool functions to archieve a dynamics like that.

 

I think I'd just use tile maps for it. For efficiency 2 layers. Most of the terrain would be 16x16 or 32x32 tiles (or larger it all depends on your target resolution). A second layer would be 4x4 or 8x8 tiles. Whenever terrain is destroyed... if a tile exists in the low res (big tile) layer then it is removed and that area in the corresponding high res (small tile) layer has tiles added to it. In all cases process the impact on the high res layer. Animating those little tiles showing destruction and leaving them a bit rough looking or simply rounded down.

This way you get the benefit of the majority of the terrain being displayed from the larger tiles (less game objects) while getting the benefit of the high resolution layer (which will only exist across the top of the terrain and where an impact has occurred).

Haven't actually made such a game but off the top of my head that is how I would approach it.

 

Hmm , Thanks for the links @DallyMoore

@GarBenjamin , is a good idea , but doing it this way it will be difficult to have a nice background ... I was thinking of something like a static image as a background , a 4x4 / 8x8 " platform " , and when the ground be destroyed , I'll remove these tiles in the impact area . But it will be difficult to build a great platform based on this idea.
