cf_easy_sprite_update_pixels

Category: sprite
GitHub: cute_sprite.h

Updates the pixels of a sprite created from cf_make_easy_sprite_from_pixels.

void cf_easy_sprite_update_pixels(CF_Sprite* sprite, const CF_Pixel* pixels);

Remarks

The real cost hides in the atlas: if this image was packed into a shared atlas page, invalidating it rebuilds that entire page, re-fetching every image on it. Fine for occasional updates; pathological every frame or in a loop over many sprites. Frequently-updated images eventually migrate to their own standalone texture (the atlas's lonely buffer), where updates only re-upload that one image -- so a per-frame video-style sprite settles into acceptable cost, but the first updates after it packs are page rebuilds. For genuinely dynamic content prefer a CF_Texture you own plus cf_texture_update, drawn through cf_draw3d_set_texture or a custom shader, which bypasses the atlas entirely.
