#Make 2d animation code

If you have an anim predicated on just looping through the frames while the 'player entity' is in some state(e.g. Some examples of how much your solution may vary: Get something drawing and then use that until it starts to break, then iterate it's a very game-design related problem, and game design is predicated on iteration, so bringing the iteration down to the engine level(rather than to fret and try to come up with a 'perfect solution' out of the gate) ends up being the best way to explore this aspect of gameplay. You haven't given enough information about the environment, the planned game design, and your current engine structure to suggest anything specific, so here's the general advice:

#Make 2d animation code

Now that I've given you a complete code sample, will you please stop bothering me about your game? :P

GlTexCoord2f(end_u, end_u) glVertex3f(x + (width / 2), y + (height / 2), 0) GlTexCoord2f(begin_u, end_u) glVertex3f(x - (width / 2), y + (height / 2), 0) GlTexCoord2f(end_u, begin_v) glVertex3f(x + (width / 2), y - (height / 2), 0) GlTexCoord2f(begin_u, begin_v) glVertex3f(x - (width / 2), y - (height / 2), 0) To get a frame from your strip, simply do: float step_size_x = (float)(width) / (float)(texture_width) įloat step_size_y = (float)(height) / (float)(texture_height) įloat begin_u = step_size_x * step_current_x įloat begin_v = step_size_y * step_current_y įloat end_u = begin_x + step_size_x // basically, if you want sprite 0, you go from 0 to the x of sprite 1Īnd that's it! Now if you want to copy the portion of the texture, that would be the following in OpenGL: glBindTexture(GL_TEXTURE_2D, texture_id) If your sprite is 32 pixels wide and your texture is 256 pixels wide (thus containing 8 frames), you'll want to divide the width of the sprite by the width of the texture, giving you a number between. Seeing as you're using the UV coordinates of the texture that contains all your animation states, you'll need to convert from pixel coordinates to UV coordinates.
