First, take the Y dimension of your grid. Multiply this value by negative 0. Following this formula, a grid that has the dimensions 1, 0. At this axis sort value, any 1, 0. If you want to find out more about where this value and calculation comes from, take a look at the documentation here. It explains in great depth how 2D renderers work, and what method is used when converting isometric cells into world space values.
Now that we have some tiles placed higher than others, we can control the areas that the player can go to and transition between them using collision. Instead, we can define collision by hand using an additional Tilemap. In this project, we have created some sprites that correspond to the different shapes that we will use to define our collision areas.
We can paint these shapes onto our third Tilemap, in the areas that we do not want the player to pass over. For example, we want the player to be able to ascend to the cliff only using the ramp, rather than walking onto it directly.
We can also add a custom Material in our Tilemap Renderer component in order to tint the tiles a different color that is distinct from the rest of our level. Once we have placed our collision tiles, we can add a Tilemap Collider component to the collision Tilemap. This will auto-generate colliders for each individual tile based on the shape of the sprite. For better performance, we can also add a Composite Collider 2D component, and make sure to tick Used by Composite on our Tilemap Collider.
This unifies all of our individual colliders into one big shape. Adding props to the level is quite simple. You can either manually place the prop sprites at any desired point in the scene, or you can attach the props to the Tilemap Grid by making them into individual tiles.
You can decide which approach works best for your case. The trees and the character have the same Order in Layer, allowing our character to sort behind and in front of them dynamically. We can define the point at which the player can pass the tree by using a collider. There are several ways in which we can do this. The first one, as demonstrated in the videos, is to attach a child collider to the object, and change its shape as needed. In the top-left dropdown, switch to the Custom Physics Shape editor.
Here, you are able to create a polygonal shape to define the bounds of your custom collider. Once you have defined a physics shape, you can attach a Polygon Collider component to your object, and it will correspond to that shape. If you are using your props as tiles on a Tilemap, you could also use a Grid collider.
Select the Tile Asset that corresponds to a prop tile if you need a refresher on where to find it, take a look at the Basic Tilemap Workflow section. You will be able to see a dropdown setting for the Collider Type.
By default, it is set to sprite - meaning the auto-generated collider will use the Physics Shape we talked about earlier. If you set it to grid, however, it will always exactly match with the shape of the grid cell that the prop is attached to.
It may not be the most accurate way of implementing colliders but could be useful for a specific type of game. To use the grid colliders for these tiles, select the Tilemap with your props and add a Tilemap Collider component.
Rule Tiles are extremely useful when it comes to automating the tile painting workflow. A Rule Tile acts as a normal tile, with an additional list of tiling parameters.
Using these parameters - or rules - the tile can automatically choose which sprite should be painted based on its neighboring tiles. Rule Tiles are useful when you want to avoid hand-picking differently rotated tiles - for example, when creating a cliff or platform. They can also be used to randomize between different variations of the same tile to avoid obvious patterns, and even to create animated tiles. They also contain many other handy assets for the Tilemap feature that you may want to explore.
We have also included pre-configured Rule Tiles for each of the different tilesets in our Isometric Starter Kit project. Here are some examples of the tiles included in the project for you to experiment with:. Ideally, I want to treat all wall tiles equally. Any help is appreciated. I've been worrying about this for days, but maybe I'm thinking too complicated :.
Note what happens when wall tiles are simply scaled. This works well for front facing walls only. I want to thank everyone who took their time to respond to my question. I finally came up with my own solution, which nevertheless was inspired by the suggestions here.
Especially this comment from Ali. S turned out to be particularly useful:. Just an idea, but you can provide your shader with another texture, representing the height of that pixel, and take that information into account — Ali.
S Dec 13 at Instead of using another texture with height information, I went for an approximate approach. I store for each tile a line that passes through the two ends of the wall at ground height:.
Now it is possible to scale the two sides of each tile differently, according to the y-coordinate of the line's endpoints. However, in case of the corner tile, this leads to distortions because the wall does not exactly coincide with the line.
Fortunately, these distortions are not a big problem since I only plan to apply a subtle perspective effect. This makes the distortions hardly noticeable, unlike in the image above, where perspective is highly exaggerated for illustrative purposes. I would try using a screen buffer to draw all the walls and possibly the characters to. And then you can apply the perspective to all the walls at once.
This should eliminate any errors you are getting because perspective is being applied to a single image rather than multiple images. You would than assemble the scene by drawing floor layer and then the wall layer on top of it.
You're right in that, visually speaking, there appears to be a larger difference between 0deg and 10deg than between 90deg and deg.
If you don't want that look, you don't want isometric. That said, I think the visual issues you're having are thanks to not having a visual reference point. Your brain is assuming you're looking at it top-down - hey, it's space, why wouldn't you be - and so is interpreting it as a standard top-down view. For the sake of testing, try adding some floating holographic reference points.
A degree angled grid, for example, or a set of range circles around your spacecraft. Make sure they're appropriately distorted as if they were on the same isometric plane your spaceship is rendered on. I'd wager that your brain will figure out the perspective and it will suddenly look right.

END EDIT It looks rather odd when this ship is shooting a laser beam at a target that is off to one side, when it should be shooting straight ahead.
Rotate my world already. PS: this will fix my problem, right? Alter my sprite sheet somehow to have frames that represent the "screen angle" that the model will be viewed at. So when I ask for a 45 degree image, it will actually look like it's facing 45 degrees on the screen.
Alter my sprite rendering system to grab a different frame from the sprite sheet somehow , knowing that grabbing the "normal" frame will look funny. So instead of grabbing the 45 degree frame, it will grab the Just use 3D! It's so much easier man For one: Which solution would you recommend?
EDIT Sept 8 Continuing from my "thinking out loud" paragraph: Instead of using a projection because it looks hard I'm thinking I could take a north facing unit vector 0x,1y,0z , use a matrix to rotate it to the angle the sprite is actually facing, then rotate it again from the "viewing plane" outward to the "sprite plane" around the X axis, then Transform vect, Matrix.
