Any plans of implementing a 2d sprite system?

or is fplbase only 3d?

If you can render 3d, 2d is a breeze. For example, FlatUI sets up an orthographic projection matrix for 2D rendering using fplbase. Already interested in giving it a try?

Cheers,

Stewart

i was already looking at sdl as a cross platform possibility

so this fplbase really comes as a welcome surprise at the right time

the only thing that was a ? in sdl was the 2d sprite support

i would like to see if fplbase gains enough interest from devs, that someone builds a 2d sprite system on top

seems you are asking some sort of sprite lib or 2D lib on top of the fplbaselib to attract more developers?

Many devs go to SFML as it has a 2d sprite lib, whilst SDL does not.

So if FPLbase can change that, then I bet a lot of devs will find interest in FPLbase as SDL is more solid when it comes to multiplatform

Let's wait and see if this will gain any traction

Right now, rendering sprites is relatively easy (see documentation for more detail):

Set up an ortho matrix
Append matrices that represent 2d rotation/translation/scaling if necessary.
Set shaders & textures as usual.
Use e.g. the convenient Mesh::RenderAAQuadAlongX to render a quad.

I agree that's not quite convenient enough though, and besides wrapping the above in more convenient functions, some batching (using instancing) to make it efficient for large numbers of sprites would be great.
