Three shapes, two text, three textures, one models and one core, picked for
binding surface rather than for how they look.
shapes-basic-shapes brings in six draw families nothing had called — the
circle and rectangle gradients, the triangles, all three poly draws — and is
the first call in the corpus to pass two Colors or three Vector2s at once.
shapes-collision-area is get-collision-rec, the only binding that takes two
Rectangles and answers a third, on a frame path. shapes-following-eyes is the
raymath gap measured rather than worked around: every line of it is vector
arithmetic written without a vector library, the way the C writes it.
text-input-box drains get-char-pressed's queue, which no example had read,
and needed a MouseCursor defenum for set-mouse-cursor. text-writing-anim
replaces TextSubtext — unbindable, it answers a pointer into a rotating
static buffer — with (string (slice b 0 n)), which is the same operation
without the shared state.
textures-image-generation runs nine Gen* calls and the
gen/upload/unload-image path, all procedural, no file on disk.
textures-fog-of-war needed a TextureFilter defenum: the smooth fog edge is
entirely :bilinear on a 25x15 render texture, and it is also the first
draw-texture-pro with a negative source height. textures-mouse-painting is
the same render texture used as a document rather than as scratch, plus the
round trip back off the GPU — load-image-from-texture, image-flip-vertical,
export-image — which nothing had run.
models-box-collisions is the counterexample to "a models example is a binding
exercise": nothing in it is a Model, and one BoundingBox defstruct un-refuses
four functions. core-3d-picking is the only caller anywhere for Ray and
RayCollision, and picking is the inverse of the get-world-to-screen the
corpus already had.
Added to vendor/raylib: defstructs BoundingBox, Ray and RayCollision;
defenums MouseCursor and TextureFilter with their mapping lines in bindings;
hand-written declare-c for SetMouseCursor, SetTextureFilter, DrawCubeV,
DrawSphere, DrawSphereWires, DrawRay and GetScreenToWorldRay, each excluded
from the generated half on the rule bindings already states. generated.flan
regenerated against raylib 5.5: 272 declarations, 117 refused, every
defstruct, hand-written declare-c and mapped constant agreeing with the
header.
