[android-developers] Re: Sprite imaging for 2D game programming
Take a look at the Canvas method drawBitmap() http://developer.android.com/reference/android/graphics/Canvas.html#drawBitmap(android.graphics.Bitmap,%20android.graphics.Rect,%20android.graphics.Rect,%20android.graphics.Paint) with that one you can specify the bitmap (the sprite sheet), the subset of the bitmap you want to display (the current frame) and the destination on the screen. To make it animate you'll want to keep track of the amount of time you've displayed the current frame, you can do this by updating a counter by the amount of time that passes between each update call e.g. when you update model position etc. When it exceeds whatever you've decided to be your frame-rate you change the current frame and reset the timer. I'll see if I can make some of my code a little more readable and post it up later if you're still stuck.

I basically used one bitmap, and a call to canvas after a specified amount of time using a different drawing rectangle, and some canvas transformations On May 18, 4:18 am, Genc gmt...@gmail.com wrote: That's great guys, thanks a lot!

take a look at this reference http://developer.android.com/guide/topics/resources/available-resources.html and take a look through some of the tutorials here http://www.anddev.org/ On May 17, 10:23 am, g1port.com gmt...@gmail.com wrote: Hi guys, For a 2D game programming, I'm trying to learn about loading an image file for all states of a game character (simply a walking soldier lets say) and simply animate it.
