runtime_test

Test integrado del runtime nucleo gamedev. Si compila y corre, el stack 0072b esta verde.

Modo --self-test

Corre 60 frames con audio init no-fatal (CI sin device de audio sigue pasando), 3 sprites animados, input procesando eventos vacios, salida exit 0.

./build/apps/runtime_test/runtime_test --self-test

Modo interactivo

./build/apps/runtime_test/runtime_test

Pulsa Esc o Back (gamepad) para salir.

Que ejercita

• sokol_setup_cpp_gfx — make_environment + make_swapchain.
• sprite_batch_cpp_gfx — 3 sprites por frame con tint distinto.
• audio_engine_cpp_gamedev — engine_init / engine_shutdown.
• input_unified_cpp_gamedev — input_begin_frame / input_process_event con SDL_Events.
• camera_2d_cpp_gamedev — view_proj_matrix.
• game_loop_cpp_gamedev — loop_run con fixed timestep + emscripten branch.
• Tipos Vec2, Rect, Color de cpp/functions/core/math2d.h.

Notas

• NO carga assets de disco. Crea textura 2x2 blanca en GPU para alimentar sprite_batch. Asi el self-test es asset-free.
• Audio init es no-fatal: si no hay device, registra error y sigue. Permite correr en CI / WSL sin audio.
• Sin ImGui en este test (a diferencia de engine_smoke). Reduce binary size y aisla la validacion del runtime puro.
