Is there any open source 2D game developped by irrlicht

[fengjilanghen]

i've use irrlicht developped a flappy bird. but i don't think i 've fully use irrlicht's high performance .because i just use draw2DImage to render all my game. is there any more efficient way to do this? maybe some open source 2D game can teach me how to make better use of irrlicht when develop 2D game using irrlicht.
ps: i'm new in irrlicht~ just 2 weeks

Welcome to Irrlicht. Sorry - don't know a 2D open-source game right now, but draw2DImage is probably fine when it comes to efficiency. It's disadvantage is rather that it's hard to do special effects (like rotations or zooming) that way.

oh, thanks for your reply!
In my game, I have just one texture, the texture have many kinds of elements, such as bird, pipes, nums and so on. when draw a bird, I transform the bird's vertex, when draw pipes, I transform pipes' vertex. can I combine bird vertex and pipes' vertex , an then transform them together to opengl? any member function available?

The functions for direct driver are all in IVideoDriver. Take a look at that.
I'm not sure what exactly you tried to describe.
