Do you find the problem is improved if you cache a reference to the camera once, rather than searching for it every FixedUpdate? Active Oldest Votes.

Understanding Screen Point, World Point and Viewport point in Unity3D forms the basics of how camera can be used while determining the position of an object or mouse pointer. Screen point is defined in pixels. The bottom-left of the screen is 0,0 ; bottom-right of the screen is pixelWidth ,0left-top is 0, pixelHeight and the right-top is pixelWidth,pixelHeight. The bottom-left of the screen is 0,0 ; bottom-right of the screen is ,0top-left is 0, and the top-right isThe centre point will be This point can be used to find which half of the screen is touched.

Another usage of this point may be to move an object to the point where the screen is clicked. It is illustrated in the coming sections. A viewport space point is normalized and relative to the Camera. The points on the screen range between 0 and 1.

Understanding Screen Point, World Point and Viewport Point in Unity3D

You can determine the the x-coordinate by dividing the screenPoint. Accordingly, the bottom-left of the Camera is 0,0 ; bottom-right is 1,0 the top-right is 1,1 ; top-left is 0, 1. The centre point will be 0. An important point to note is that the viewport point is relative to the camera and an object placed according to the view port point stays at the same place on the screen always.

A world space point is defined in global coordinates for example, Transform. It is the position of the object in world or global space. Unity offers in-built functions to inter-convert world point, viewport point and space points into each other. Let us see an example on how to move from world to screen point and vice versa. If there is an object lying in the world space and you want to move it to the position where you click not changing the z position of the objectyou can use the following set of code:.

This point will help you keep the object in-tact in z-axis. The new position of the object is fetched by converting the screen position of mousePointer in x and y axis and the screen position of object in z-axis.

I would assume that this is related to the different mathematical formulas required to calculate the world points which haven't been implemented in the edit mode or the play mode? Or it could be me missing important information, or there is a known workaround for orthographic cameras which I haven't been able to find. I think this is because the camera dimensions depend upon the viewport dimensions, and those dimensions change between Play and Edit mode.

This is because the camera dimensions are normalized. If you want non-normalized dimensions, I think you need to use the "pixelRect" property via code it's not exposed in the inspector.

Thank you. This already helped out a lot. But now I'm facing another problem: A transform should have a specific offset from the top left corner of my camera. The problem is that it that the offset gets completely screwed up if the game view gets resized on the y-axis.

Its probably related to the the aspect ratio of the camera changing. But the weird thing is that everything says fine if the game view gets resized on the x-axis.

The main camera's output is set to a render texture, which is applied to a material, which is applied to a quad that's scaled up to x The secondary camera is set to only see what is rendered to the child quad, who has the material with the render texture on it.

However Camera. ScreenToWorldPoint Input. The GameObject is instantiated at 0, 0, 0and hovering over it shows the mouse at EDIT: Using a single orthographic camera, all properties the same except for using a render texture, instead of the setup I have now results in accurate ScreenToWorldPoint output. The Input. ScreenToWorldPoint requires the z axis too which Input. The z-axis value supposed to be the nearClipPlane of the camera. It will give you a position that's right in front of the camera.

Depending on the size of the 3D object you want to instantiate where mouse button is pressed, you will need to apply an offset to it to make it totally visible to the screen. For a simple cube created in Unity, an offset of 2 is fine. Anything bigger than that, you will need to increase the offset. You may not be calling the Camera.
