Easy Tilemaps and Dynamic Auto Tiling - Unity 2D

In this video we'll create a tilemap, add a collider (so we can use it as platforms or walls) and also look at creating dynamic tilemaps using Auto Tiling and Tile Rules!

By implementing tile rules, you can paint on your scene and it'll automatically place the correct sprites depending on the other sprites around it - it's really cool!

On my Patreon you can get the package which includes this Tilemap and Rule Tile - so you don't have to set it up yourself:

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.

Good for a refresher on how to do it, People new to unity might struggle to follow along, Helped me so I like though

How would you make a platform made from tileMap falling for example ? I have a script working for gameobjects I created ( Like a rectangle platform ), but I can't attach those to tile maps ?

[johnathansuda]

Any experience with incorporating navmesh with tile mapping?

[mysticowlgames]

How would you work with sliding colliders or slopes in Rule Tiles? I am unable to figure it out

[bluzenkk]

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

[kaviyy]

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

[AlwynCho]

useful tutorial thankyou! keep good work

[EpicHashTime]

Why is the pixel per unit set to 15 instead of 16?

[dreamspheree]

I am using slopes in the tile map and the collider is not pixel perfect . And the character looks like it's floating

The moment I saw aseprite I immediately sub 😂
