Re: [android-developers] Drawing on a canvas like normal VS OpenGl

2011-01-08 Thread Leigh McRae 
  Going with OpenGL increases the complexity of the game as you now 
have to deal with activity life cycle issues and drivers.   You also now 
have to manage creating and loading textures.  All these things can be 
managed of course but they will have to be managed and hence will 
require more effort on your part.


  I have released Freddy Jump, Freddy Falling and Wrath all using 
regular canvas calls.  They all have lite versions if you want to check 
them out.  None of these games have a performance problem AFAIK but they 
are pretty basic.


  If your game requires sprite scaling or rotations, then I think you 
should consider OpenGL.  Freddy Jump has rotations on Freddy but the 
scenery is sparse.  If you're just starting out I would strongly suggest 
making a simple game that uses Canvas.

It really depends on what you're doing.There are certain things that are
simply not possible or simply slower with OpenGL (e.g. high-quality
anti-aliased vector rendering being one of them). Also not all GLES
driver/chips are the same, and your performance may vary.
