In response to: "Why is the pixel per unit set to 15 instead of 16❓" You can try it out with 16x16 - but with exact sizing with sprites this can cause tearing: you’ll see white lines flickering between your tiles! To fix this I use the easy way of setting the pixel per unit to be one less, which means we have a bleed edge - an overflow for the sprites! There are two other ways I know to fix this: 1. Manually edit your sprites to be bigger with a bleed overlay: so add a few extra padded pixels around all edges so it’s say 18x18, then you can use 16x16 in Unity safely! (Time consuming!) 2. Use a sprite atlas (found in the 2D menu) where you add an entry for each sprite in your tile map. Since this is a quick and easy version, I did my lazy way which I use for small projects! In professional level production you can use one of the above methods.

not sure if the tearing is the same issue, but i just saw another video on tilemaps by MoreBBlakeyyy where he shows that turning off anti-aliasing in the project settings fixes this.

You can fix this issue by just creating a sprite atlas of all sprites used with tiles. Hope it helps :)

Hey! I haven't tried it out myself, but I've seen this cool video for handling slopes and rule tiles! kzread.info/dash/bejne/lphlqMdsccy9lNo.html However, it's a paid for tool. I haven't seen anyone else work with rule tiles and slopes! So you could manually add the slope on after painting your map out with rule tiles simple block shapes! Sorry I couldn't help more, good luck :-)

can you make a tutorial on using LDtk or Tiled. I think that will improve workflow than using the unity tile map edit.

@@GameCodeLibrary thanks for keeping an open mind. I've been digging to find more tutorials on Tiled Edit and LDtk. cuz i saw a KZreadr use Tiled and automated the workflow of adding collision and new tiles so effciently that makes the Unity Tilemap look so obsolete.

The used by composite part does not appear for me... what is the reason?

@GameCodeLibrary

7 ай бұрын

Sorry for such a late reply! Was away this week :p On your actual tilemap component, make sure you add a Tilemap Collider 2D and then a Composite Collider 2D. After the Composite Collider 2D is added, the tick box should appear on your Tilemap Collider 2D. When ticked, it should merge your multiple tile colliders into one big collider! If it doesn't appear to - try resetting your project and seeing if your collider has updated. Hope this helps!

It's always a good idea to give a little "wiggle room" to everything. Otherwise, collisions, layering, and even mechanics can look... well... too rigid and mechanical. In the original "Pac Man" game (1980's), controlling mr Pac guy allowed for "rounded" cornering during player manipulation. The ghost enemies were NOT permitted to do this. 🙂 This is why it was easier for players to gain ground and escape ghosts in "J-bends" or multiple curves as opposed to straightaways. What does this have to do with 15 pixels vs. 16? Well, the CORNERS of ledges can be rounded as well. This allows players to leap up to ledges (or fall from them) with less rigidity and blockiness. 🙂 🐲✨🐲✨🐲✨
