This form of projection is commonly used in isometric video games to simulate three-dimensional depth. More info See in Glossary or true isometric projection A form of parallel projection where the dimensions of a 3D object are projected onto a 2D plane, and the angles between all three axes are equal to each other.
Isometric Tilemaps use either dimetric projection A form of parallel projection where the dimensions of a 3D object are projected onto a 2D plane, and only two of the three angles between the axes are equal to each other. This causes the Tile to be visually offset along the Y-axis by that value, creating the illusion of height as the Tiles are placed on the Tilemap. Grid Cell Size settings Grid with default Isometric Layout settings IsometricĬreates an Isometric Tilemap with the default settings.Ĭreates an Isometric Tilemap where a Tile’s Z-axis value is added to its Y-axis value. The Z-axis is set to –0.26 to give a bias to Tiles with higher Z positions to be drawn first. Set the Transparency Sort Axis to (0,1,–0.26) to correctly render Tiles with different Z positions. Right: With (0,1,–0.26), Tiles appear correctly ‘stacked’ on each other. Left: With (0,1,0), Tiles rendered in incorrect order. By default, the generic isometric Transparency Sort Axis setting of (0,1,0) does not consider the Tile’s Z-position values during sorting which results in the Tiles being rendered out of intended order (see the example below). With the Isometric Z as Y Tilemap, Tiles with different Z-position values are offset along the Y-axis and appear to be at different heights, producing a ‘stacking’ effect with Tiles at the same XY Cell Position. Set the Transparency Sort Axis XYZ values to (0,1,0) to cause all Renderers which are at a higher Y position in the Scene to be rendered first, and appear behind Renderers at a lower Y position. Go to Edit > Project Settings… > Graphics > Camera Settings to set the ‘Custom Axis’ settings. Set the Transparency Sort Mode to ‘Custom Axis’ and enter (0,1,0) for the XYZ values of the Transparency Sort Axis. More info See in Glossary conform to this logic, a Custom Axis is used as the Sorting Axis.
In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces.
Think of each unique Scene file as a unique level. To ensure that all Renderers in the Scene A Scene contains the environments and menus of your game. More info See in Glossary of an isometric perspective. To render the Tiles of an Isometric Tilemap, Tiles placed further to the ‘back’ of the Tilemap need to be rendered first before those in front to create the pseudo-depth A visual simulation of three-dimensional characteristics on a two-dimensional object or environment. More info See in Glossary, there are additional settings that need to set with the Project and Grid settings for the Isometric Tilemap to be rendered properly. To create an Isometric Tilemap, go to GameObject > 2D Object > Isometric Tilemap/Isometric Z as Y Tilemap.Īfter creating the Isometric Tilemap A GameObject that allows you to quickly create 2D levels using tiles and a grid overlay. When creating an Isometric Tilemap, there are additional steps to take compared to creating a regular Tilemap.
