I posted something on the 2D forums a week ago. If tiles are changing at runtime, how do you force the Tilemap or RuleTile to update? The ITilemap functions are callbacks from the Tilemap to the Tile to retrieve information from the Tile.

For now I'm using tilemap. RefreshAllTiles but that's horribly inefficient for large Tilemaps. Do you have any suggestions for how to use RuleTile. The RuleTile's RefreshTile function refreshes the RuleTile at the given position for the given Tilemap, so if the above is correct, that will not do what you want. I guess the Tilemap would need a new function to do this which would be tilemap. RefreshTiles Tilebase tile?

Thank you for spending time looking into this. It is much appreciated. I could see someone using both of the scenarios you mentioned above, however my use case is different. I have a Tilemap on which only one type of Tile is placed and it's a RuleTile. The user is "digging" and whenever they dig, as long as they haven't previously dug there, a RuleTile is placed on the Tilemap at that location.

So if I dig at location 0,0, it adds a RuleTile to the Tilemap. If I then dig at location 0,1, it adds a RuleTile.

Since those two tiles are touching, and since there's a rule for those scenarios e. I hope that makes sense.Feel free to customise the behavior of the scripts to create new tools for your use case!

Line : This Brush helps draw lines of Tiles onto a Tilemap. The first click of the mouse sets the starting point of the line and the second click sets the ending point of the line and draws the lines of Tiles. Use this as an example to modify brush painting behaviour to making painting quicker with less actions. Random : This Brush helps to place random Tiles onto a Tilemap. Use this as an example to create brushes which store specific data per brush and to make brushes which randomize behaviour.

Prefab : This Brush instances and places a randomly selected Prefabs onto the targeted location and parents the instanced object to the paint target. Use this as an example to quickly place an assorted type of GameObjects onto structured locations.

Use this as an example to create brushes which targets objects other than tiles for manipulation. TintBrush : Brush to edit Tilemap per-cell tint colors. TintBrushSmooth : Advanced tint brush for interpolated tint color per-cell. Requires the use of custom shader see TintedTilemap.

Pipeline : Pipeline Tiles are tiles which take into consideration its orthogonal neighboring tiles and displays a sprite depending on whether the neighboring tile is the same tile. Random : Random Tiles are tiles which pseudo-randomly pick a sprite from a given list of sprites and a target location, and displays that sprite. Terrain : Terrain Tiles, similar to Pipeline Tiles, are tiles which take into consideration its orthogonal and diagonal neighboring tiles and displays a sprite depending on whether the neighboring tile is the same tile.

RuleTile : Generic visual tile for creating different tilesets like terrain, pipeline, random or animated tiles. Other GridInformation : A simple MonoBehaviour that stores and provides information based on Grid positions and keywords.

Show all projects by Manako.A 2D tilemap-based video game is any game in which the levels or play areas consist of many small tile-based shapes that collectively form a grid of tiles. Sometimes, the distinction between each tile can be obvious but it might also be seamless and unrecognizable to players. The collection of tiles available in the game are known as a tileset, and each tile will usually be a sprite that is a part of a spritesheet.

If you want to brush up on spritesheets, here is a Unity tutorial that covers spritesheets. But they also come in other shapes such as rectangles, parallelograms or hexagons.

Games usually use a top-down or side view perspective, but tile-based games offer 2. You may already be familiar with two well-known games that use a tilemapping system: Starbound and Terraria. Next, extract the. Fire up the Unity editor and load the Rayzor-starter project from the extracted project materials package. Click the Play button in the editor to start the game.

Introduction to the New Unity 2D Tilemap System

Now, if only Unity offered this feature…. Leave the grid and cell options as their defaults. Underneath this, create a new folder called RoguelikeCave. Next, highlight all the sprites in this spritesheet: select the first sprite, hold shift, and then select the last sprite. After you drop the sprites into the Tile Palette window, use the location prompt from Unity to select a location to store the tile assets. Unity will generate a tile asset for every sprite you added from the spritesheet.

Wait for this to complete, then resize your Tile Palette window and marvel at your shiny new tiles laid out neatly on the RoguelikeCave palette:. Repeat the above process of creating a tile palette using the Tile Palette window but, this time, name the new palette RoguelikeCustom.

Place the newly created palette in a new folder. Create a folder called Tiles under your RoguelikeCustom palette folder and place your tile assets there:. You should see a Grid GameObject added to your scene Hierarchy.

Expand this and select the nested Tilemap GameObject. Think of this Tilemap object as one layer — of potentially many — in your game. You can add more of these to build more Tilemap layers.

With the Tile Palette window still open, make sure you have the RoguelikeCave palette selected, then select the brush tool or press B. Select the sandy tile as shown below:.

Using the Scene window, hover your mouse cursor over the grid near the player. The sand tile brush will snap to the grid. Click and hold your left mouse button, and paint a rectangular area around your player. This will paint to your BaseLayer Tilemap layer:. Painting large areas can be tedious, so there is a Filled Box brush that you can use for larger section painting. In the Tile Palette window, click the square brush icon or press U. Return to the editor and paint an even larger rectangle around the player by clicking and holding your left mouse button at the top left corner and dragging down to the bottom right, then releasing your mouse button:.

This time, it will be the only object created in the Hierarchy because you already have a valid Grid. Rename this layer DungeonFloorDecoration :.

Make sure you select the brush tool Bthen use the Scene window to paint down a number of random grunge-like items:. Disable and then re-enable the DungeonFloorDecoration GameObject in the Hierarchy to see how painting with the active Tilemap changed your DungeonFloorDecoration layer, ensuring that all newly painted tiles went onto this new layer:.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
