neoGFX animation is as simple as...

[Mr Flibble]

auto const explosionMaterial = ng::game::material
{
{}, {},
ecs.shared_component<ng::game::texture>().populate("explosion", ng::to_ecs_component(ng::image{ ":/test/resources/explosion.png" }))
};
auto const explosionAnimation = ng::game::animation_filter
{
ecs.shared_component<ng::game::animation>().populate("explosion", ng::game::regular_sprite_sheet_to_animation(explosionMaterial, ng::vec2u32{ 4u, 3u }, 0.1))
};
auto explosion = ecs.create_entity(archetypes::explosion, explosionMaterial, explosionAnimation);

Wow. So simple. Why not add a few other braces here: {}, {}, {} ? Would
be even cooler!

IOW, to you it may seem simple, to me it is just gibberish. And the
nesting of different braces <({ sprinkled with names reminds me of LISP
code.

Isn't this just normal C++ code? Just reams of auto, {}, <>, :: and
liberal sprinkling of 'const'.

Graphics programming like this really needs a clean scripting language.

[Mr Flibble]

neoGFX will come with a scripting engine but I also provide the option to easily do stuff directly in C++.

I guess C++ isn't for everyone.

That was an example of how clean using neoGFX is even before further functional decomposition; I have since added more helper functions so the equiavalent code is now:

auto const explosionAnimation = ng::regular_sprite_sheet_to_renderable_animation(ecs, "explosion", ":/test/resources/explosion.png", ng::vec2u32{ 4u, 4u }, 0.05);
auto const testExplosion = ecs.create_entity(archetypes::explosion, explosionAnimation.material, explosionAnimation.filter);

I suggest you stop being such an negative egregious cockwomble and/or learn to use C++ properly.

[Bart]

Even this is too long-winded to grok in one glance. It is basically
doing something like this:

expAnim = rss2ra(ecs, "explosion", "expl.png", (4,4), 0.05)
testExp = create_entity(explosion, expAnim.material, expAnim.filter)
