For best results, the Near Plane should be set to a very large negative number. Size and Clipping Planes define the Orthographic Frustum. It’s fine to have XY data in your map assets, but do convert it to XZ data so that you can operate on it using the named constant vectors, and orient your models in an expected way. This will save you a ton of headaches later on. We can remap the Physics Up Vector (aka gravity), and we can re-orient models at runtime using extra transforms (less efficient but not a show-stopper), but we cannot redefine Unity’s built in constants for Vector3.Up, Vector3.Right, and Vector3.Forward.įor this reason I strongly suggest orienting your world map structure such that XZ are the landscape coordinates and Y is UP.

More importantly, Unity has provided named constants for the Cardinal Vectors for us - Right (x), Up (Y), Forward (Z) - and if we re-orient the entire world to suit a paradigm where Z=Up, those named constants become confusing/misleading. Why does it matter? Because the majority of GameObjects, models, and Unity components (most notably the Physics components) default to the assumption that the Up Vector is the Y vector. Contrast this with most 3D engines, and Unity specifically, which treat the X and Z vectors as map surface, and the Y as the Up Vector. This has a long history in isometrics being used primarily to depict 2D landscapes, and 2D coordinate systems naturally use X/Y mnemonics. The classic view of an isometric map has X and Y axis for the map surface, and Z as the Up Vector. (/end SEO) Tip #1: Use X/Z coordinates for landscaping In this entry, I will explain how I implemented a flexible solution to controlling the camera, within the context of the Unit圓D 2019 engine. (shameless SEO paragraph) The orthographic camera is a staple of Isometric Gameplay Environment, such as both realtime (RTS) and especially turn based (TBS) strategy games. During the process of accomplishing some modest goals in isometric gameplay, I’ve taken notes on mistakes and oversights I made while rigging my first orthographic cameras.
