wait I could actually make Minecraft with this. like using the world blocks. I’ll work on that. ---

I absolutely love the comments and notes on the engine, so thank you so much – truly. Some updates have been pushed out; they might take a while to refresh for projects that already have U3D: * * * ## **Changes from v0.4.0 - v0.4.7** New blocks: - `setSkyColor` (as @Rune mentioned) - `pauseEngine` / `resumeEngine` / `stopEngine` - `setRenderDistance` with `RenderDistance` enum - `setFOV` / `getCameraAngle` - `setMoveSpeed` / `getMoveSpeed` - `setCameraMovement` - `setTileColor` / `getTileColor` / `resetTileColor` / `resetAllTileColors` (on runtime) Other fixes: - `getTileHeight` unit fix - A/B buttons freed from engine * * * ## Comments > [@Rune](#): > > - Could you not use another tilemap to put floor textures on every tile? A: Yes, there is a way to adjust the floor texture, use the `floor` parameter in `setMaps()`: ```auto U3D.setMaps( heightmap, // Image — pixel brightness = terrain height colormap, // Image — pixel color = tile color, transparent = hole/lava floor, // <------- Image — 16×16 texture shown on transparent tiles (lava, water, void) tilemap, // TileMapData — walls and wall textures // custom shader is optional ) ``` There’s no way to change the floor texture while the engine is running; floor textures are cached at startup. I’ll add this in a future update. * * * > [@Rune](#): > > - The Distance Shading turns all of the floors 1 color down, which makes it hard to have the color you want. A: Sadly, yeah. I think this is just a hard-coded limitation at the moment. It looks great when you look at the sides of elevated terrain, but not when the terrain is at ground level, since you get the dark top faces as the floor. I’m considering some changes or adjustments to this system, but open to suggestions! * * * > [@Rune](#): > > - The Distance Shading might benefit from being able to adjust it, like changing the distance it takes to shade. A: One hundred percent, yes. There’s something similar with `setRenderDistance`, and color-mapped walls with no textures have no distance shading for performance reasons. But being able to adjust the shading distance and intensity is something I overlooked, should be really easy to implement tho. * * * > [@Rune](#): > > - I don’t know how this could be fixed, but taking the height map and color map and then attempting to tile the right spots in the tilemap is really hard, especially on bigger maps and more natural-looking areas. A: I’ve thought the same thing! My best solution would be another external tool that you can use to overlay or edit both maps at once, and lets you export the code for the maps. But there are strict rules on what external sites and links are allowed on the forums (if any, I know from experience). I’ll see if I can make a solution beyond that, but it’s something I’m prioritizing. * * * > [@happyhappyhappy](#): > > movement is buggy @happyhappyhappy Can you please elaborate? I would love to learn more. * * * > [@randomuser](#): > > Oh great addition, I totally agree, a distance shading color ramp would add a lot! This exists already, kinda? Distance shading uses the `shader` parameter in `setMaps()`; adjusting this will directly affect distance shading. The downside? It affects everything else that is shaded. A dedicated color ramp for walls is a nice thing to add, though. * * * > [@IAmMyGuy21th](#): > > meowbit 3.5 seconds p/frame. is that good? ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/3X/c/3/c308fd0d25694be772c55707025a20edfe45a57d.png) If this is the case, I would recommend a lower render distance using `setRenderDistance(U3D.RenderDistance.Low)`. But this is a little bit alarming, ngl. ---

NOPE LMAO. This is something that I need to fix, but it was a bit difficult so I pushed it to after the launch. ---

A few more notes: - For whatever reason, the world is flipped in game. Something that you put to the right becomes to the left. - It would be nice if there was a way to turn off the vertical line shading that happens on certain faces of walls. Sometimes its a nice effect, but being able to change everything is always better. - Unless I’m not understanding the camera movement blocks, some individual blocks to change camera angle and turn speed would be nice. I want to make a system that turns the camera with the mouse instead of the keys. - Now, this one may be impossible, but it would be really cool if you made the renderer a sprite in a way that could be used with the multiplayer different screens extension or whatever its called. My dreams of making an arena shooter could finally be realized! - Billboards appear as a black silhouette sometimes??? - It would be nice to have set and get blocks for billboard X, Y, Z etc. ---
