Thread: Sequence for color cycling
Post: RE: Sequence for color cycling
| Classic 2D chipsets couldn't fit the entire map of a level in video RAM, but only a small portion, a little bigger than the screen. Game code had to copy or "stream" tiles on the fly from the full lev... |

Thread: Per-pixel sprite vs tilemap collision
Post: RE: Per-pixel sprite vs tilemap collision
| Sorry, I don't understand the question. There's no such thing as sprite vs tilemap collision. You use TLN_GetLayerTile() to gather information about the playfield around specific locations, and take c... |

Thread: Collision with Tilemap Layer

You're experiencing two unrelated problems:
1. Seems that TLN_GetTileInfo() is not correctly protected against passing negative values as world coordinates, that's why sometimes "segfaults" wh... |

Thread: Tiled animation plays strange
Post: RE: Tiled animation plays strange
| Yes you're right. It seems that the animation in one layer (background) is being applied in another one (foreground). I'll debug this and publish a fix as soon as I can.
Thanks for pointing out this ... |

Thread: Remove tile from tilemap
Post: RE: Remove tile from tilemap
| Are you using the same assets you posted some days ago?
It's not needed to reconfigure layer with TLN_SetLayer() once you modify the tilemap with TLN_SetTilemapTile(), they're already linked. |

Post: RE: Remove tile from tilemap
| Welcome!
I understand the confusion, it seems more intuitive to delete a tile passing just NULL instead of a valid pointer with index 0, right? I'll add this behavior in next update |
