* Refactor texture caching in render.Engine: * New interface method: NewTexture(filename string, image.Image) * WASM immediately encodes the image to PNG and generates a JavaScript `Image()` object to load it with a data URI and keep it in memory. * SDL2 saves the bitmap to disk as it did before. * WASM: deprecate the sessionStorage for holding image data. Session storage methods panic if called. The image data is directly kept in Go memory as a js.Value holding an Image(). * Shared Memory workaround: the level.Chunk.ToBitmap() function is where chunk textures get cached, but it had no access to the render.Engine used in the game. The `pkg/shmem` package holds global pointers to common structures like the CurrentRenderEngine as a work-around. * Also shmem.Flash() so Doodle can make its d.Flash() function globally available, any sub-package can now flash text to the screen regardless of source code location. * JavaScript API for Doodads now has a global Flash() function available. * WASM: Handle window resize so Doodle can recompute its dimensions instead of scaling/shrinking the view. |
