Thread: Reflecting on its development
Post: RE: Reflecting on its development
| Hi,
SDL2 provide just the underlying mechanism to use windows and input in a portable manner. But the inner workings of both engines must be quite different. I guess the Retro Engine is much more t... |

I see, you're displaying a direct color 16 bpp image (at least). For doing this, Tilengine doesn't have anything special to offer. As you're not using any feature like raster effects, layer com... |

Thread: Tile animation (ON/OFF switch case)

I'm out on holidays now, but I'll consider it after I return. Right now there's no direct way to achieve the effect you want. It would require two new calls:

The "shilouette rendering" thing is specific to the Sega Genesis and its way to process priorities. It's not a feature, but a quirk that gets exposed when its priority system is twisted in an inc... |

There are two things that kill performance on a CPU: branching (i.e. conditionals) and scattered memory fetches. Writing a pixel -that is, writing a memory location- is way more cheaper. So it'... |

Sorry, I can't give advice on reimplementing Tilengine in another language I don't know. I can however add new features based on suggestions, or fix existing bugs |
