How to make pseudo 3D or 2.5D effect?

1.3k views Asked by At

After using Unity for over a year now for creating 3D games I'd like to do my first pseudo 3D or 2.5D game (or whatever it's called). What I mean is games like Clash of Clans or Boom Beach where objects are really 2D images rendered to give 3D feeling. Because I don't even know the correct word for that type of games it's really hard to get started. What I can think of is giving Camera rotation of (45, -45, 0) so that it looks down at the ground from the upper right corner and then creating empty gameObjects with Sprite Renderers and setting their rotation to (22.5, -45, 0) so that they face the camera. I don't know if that's how it's really done so could somebody give me a link to some neat tutorial or something because I'm stuck.

The keyword you are looking for is isometric projection.

You can use Unity to create that effect with 3D graphics. You need to set the camera rotation to (45, -45, 0) and set the Camera Projection to Orthographic.

If you want to only use 2D graphics then the graphics are made in such a way that they are drawn in an angle that it looks like you are looking at them in 45 degrees.

If you search for isometric unity then you should find a ton of tutorials for Unity.
