comment Is it possible to look up a texel from a texture in GLES2 GLSL framgent shader without using sampler?
Err? I don't really understand your question. What you describe (i.e. accessing texture memory) is actually what a sampler is meant to do. What do you think is a sampler doing?

comment Formula for Planetary Alignment
@PaulRobinson You misunderstood me (or the concept of RNGs). Random number generators are actually pseudo random number generators. They're predictable in the way that the same seed will always result in the same sequence of random numbers being generated. So let's assume you call srand(42); at the start of your program, then the very first call to rand() will always return the same result.

comment OpenGL - Asteroids clone - shooting bullets from spaceship
Check the question/answer linked by me. Rather than adding enemies, you'd be adding bullets, essentially doing the same thing.

comment Android appstore developer account, to not charge then change
You can change the prize, but you'll typically alienate your user base that way. Either introduce a price and later drop it or don't charge at all.

comment Can we use credit card/prepaid voucher payment systems in Android and iOS?
As Josh suggests, danger zone territory. :) But if you can't spend the balance outside the app, you're essentially screwed.

@Sajib-Mist While I don't know those services or apps, those definitely sound like something you could/would use outside those specific apps, which makes the whole thing acceptable. Just by allowing others to access the service/purchased stuff outside the app might be enough to make it legitime on the Play store.

Any specific reason you're not just using a three dimensional array for this?

comment How do I make an 8 bit sprite sheet using GIMP or Paint.NET?
For a transparent background, you won't have to create a new layer. Just hit Ctrl + A to select everything, then hit Del to remove everything, leaving you with a 100% transparent canvas/background layer.

comment GLSL- How to change a certain color of a sprite, to another color passed into the shader?
As I said, using shaders is perfectly fine, you might just want to think about a way to avoid branching in your code, because that may slow down some cards significantly.
