I try to build game with destroyable world (similar to Worms). I want to have world as an texture and modify color and transparency of some pixels around after explosion. I found way to build texture from drawable but I'm not sure that generating so much textures every time will not kill my device. Is there any way to access texture pixels more directly?

Textures in openGL are not mutable. To update the texture, you have to redefine the TextureRegion. Take a look at the Update Textures example in Andengine Examples: https://github.com/nicolasgramlich/AndEngineExamples/blob/GLES2/src/org/andengine/examples/UpdateTextureExample.java

So i think you're already on the right path, and I hope that doesn't make your app unplayable. I bet you'll be fine.
