(scene above from BITGEM) The shape of the viewed regionīoth perspective and orthographic cameras have a limit on how far they can “see” from their current position. The perspective and orthographic modes of viewing a scene are known as camera projections. A camera that does not diminish the size of objects with distance is referred to as orthographic and Unity cameras also have an option for this. For example, you might want to create a map or information display that is not supposed to appear exactly like a real-world object. Naturally, Unity supports perspective cameras, but for some purposes, you want to render the view without this effect. This well-known perspective effect is widely used in art and computer graphics and is important for creating a realistic scene. Perspective and orthographic cameras The same scene shown in perspective mode (left) and orthographic mode (right)Ī camera in the real world, or indeed a human eye, sees the world in a way that makes objects look smaller the farther they are from the point of view. As the GameObject moves and rotates, the displayed view moves and rotates accordingly. With these parameters set up, the camera can display what it currently “sees” to the screen. Settings on the Camera component define the size and shape of the region that falls within the view. The transform position defines the viewpoint, its forward (Z) axis defines the view direction, and its and upward (Y) axis defines the top of the screen. What a camera sees is defined by its transform and its Camera component. ![]() In Unity, you create a camera by adding a Camera component to a GameObject. Since the viewer’s screen is two-dimensional, Unity needs to capture a view and “flatten” it for display. More info See in Glossary in a three-dimensional space. A GameObject’s functionality is defined by the Components attached to it. More info See in Glossary represents GameObjects The fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. 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. ![]() All you need to do is drag this script onto the canvas, and then drag the canvas into the script's canvas field.A Unity scene A Scene contains the environments and menus of your game. The following script then reassigns the worldCamera (AKA Render Camera) to the Main Camera. What I ended up doing was creating a script that I would attach to the new scene's canvas. ![]() Is there any way to make this new canvas reference the Main Camera which belongs to a different scene? Ideally I would like to make its Render Camera the same camera that doesn't destroy itself across scenes, but it will not let me do that since the Main Camera I am using technically belongs to a different scene (although it can traverse the scenes). This causes some weird issues when I transition to the new scene, as it has no camera object set as the Render Camera. ![]() However, for each scene it enters, the new scene's canvas is set to Render Mode: Screen Space - Camera. My current approach is to have one camera that traverses across various scenes which doesn't destroy on load. I am currently having trouble with making a fade to black transition system.
