Working with isometric tiles is a bit trickier than a plain square grid. This tutorial is for beginner game programmers looking to wrap their heads around isometric math. Instead of simply handing you formulas, I intend to explain what they do and how they should be used. There are many ways of handling isometric tiles but were only going to talk about one method. This happens to be the most commonly used method. Its the way that isometry is handled in the Tiled map editor, so its definitely a good approach if you want to use that tool. Derived from a number of PyWeek entries, provides buttons, listcontrols, layout tools, file dialogs, and other assorted GUI bits for use with Pygamebased games. D Isometric Game Engine' title='2D Isometric Game Engine' />Orthographic Projection. When working in isometric project, your maps will still be a simple 2. D array or equivalent in memory just as if you were working in a simpler orthographic projection e. Our grid in map coordinates how our array looks in memory, Values are map. If youve worked with a regular square grid before which I recommend before trying isometric, the math works out pretty simple. Welcome to Asset Store.

From The Other Wiki Isometric projection is a form of graphical projection, more specifically, a form of axonometric projection. It is a method of visually. Drawing a tile to screen is simply taking the tiles coordinates and multiplying by the tile size to get the screen position. TILEWIDTH. screen. TILEHEIGHT. In this example our tiles are 6. If we want to display the tile at position 2,1, we plug the values into our formulae. Determining the screen position for a tile in Orthographic Projection. Isometric Projection. This figure shows how we want to project our memory tiles to the screen in Isometric view. We want our map to look like this on the screen. In this example our isometric tiles are 1. Lets draw tile 2,1 again, but this time in isometric projection. First lets measure some pixels to see where tile 2,1 is on the screen compared to the origin point so we know what answer were working towards. Tile 2,1 position in screen pixels is 6. Heres where its easy to get brain bent. Its possible to calculate rotation and y scale to do this, but theres a simpler way. The trick is to think of x and y separately. Observe the following about this isometric projection. Increasing map X by 1 tile going right in map coordinates increases both screen X and Y going right down in screen coordinates. If we measure in our example, well see that it increases screen. Similarly, increasing map Y by 1 tile going down in map coordinates decreases screen X and increases screen Y going left down in screen coordinates. Expressing those changes as code looks something like this. TILEWIDTHHALF map. TILEWIDTHHALF. screen. TILEHEIGHTHALF map. TILEHEIGHTHALF. And with some simplification we get the basic formula for isometric projection. TILEWIDTHHALF. screen. TILEHEIGHTHALF. Lets test the formula on tile 2,1 to see if we get the expected result. Projecting from Screen pixels back to Map position. Now a square grid is easy to work with. Probably all of your game calculations e. You only project to screen pixels when you need to draw something. Sometimes though you have to convert screen pixels back to map coordinates. Example the player clicks on a pixel how do we reverse the formula and find the tile Rather than figure out the formula from the inputsoutputs this time, were going to use good old Algebra to reverse the functions. Basic isometric map to screen is. TILEWIDTHHALF. screen. TILEHEIGHTHALF. Solve the first equation for map. TILEWIDTHHALF. screen. TILEWIDTHHALF map. TILEWIDTHHALF map. Solve the second equation for map. TILEHEIGHTHALF. TILEHEIGHTHALF map. TILEHEIGHTHALF map. Replace map. y in the first equation with what it equals in the second. TILEWIDTHHALF map. TILEWIDTHHALF screen. TILEHEIGHTHALF map. TILEWIDTHHALF screen. TILEHEIGHTHALF. TILEWIDTHHALF screen. TILEHEIGHTHALF 2. And now do the same for map. TILEHEIGHTHALF screen. TILEWIDTHHALF map. TILEHEIGHTHALF screen. TILEWIDTHHALF map. TILEHEIGHTHALF screen. TILEWIDTHHALF. TILEHEIGHTHALF screen. TILEWIDTHHALF 2. So final actual commands are. TILEWIDTHHALF screen. TILEHEIGHTHALF 2. TILEHEIGHTHALF screen. TILEWIDTHHALF 2. Given screen pixel coordinates 6. TILEWIDTHHALF screen. TILEHEIGHTHALF 2. TILEHEIGHTHALF screen. TILEWIDTHHALF 2. Notice that the origin of the isometric tile is the top corner. But usually when we draw a sprite its from the top left corner. Before drawing you may want to adjust by the tiles size. Example for regular sized tiles screen. TILEWIDTHHALF. These formulas also dont account for a camera. Essentially a camera is a drawing offset, just as in an Orthographic game. The middle of our projected map is at x0, so if you want it centered on the screen its like having a camera offset screen. SCREENWIDTHHALF. Note that these formulas work for sub tile positions as well. Assuming youre doing all floating point math, the map position 2. If youre going to use floats anyway, you can simplify the screentomap functions slightly because youre not concerned with integer division. TILEWIDTH screen. TILEHEIGHT. map. TILEHEIGHT screen. TILEWIDTH. I suggest setting up two utility functions for quick conversion between screen and map coordinates. Remember to do all the actual calculations in map coordinates, and only project tofrom screen coordinates for inputs clicktouch and outputs rendering. Point maptoscreenPoint mapcoordinates.
