I’m looking for help trying to create a camera controller that mimics the scene view camera controls.
The unity manual lists the scene view navigation as such:
Specifically I am looking for these types of controls:
Hold right click and mouse input to pan left, right, up, and down
Hold right click and hold input w, s, a, and d to fly through forward, and back, and strafe left, and right, respectively at speeds that increase the longer the input is held down
Double left click to focus on target and move to set distance at a smoothed rate
Hold alt and right click to orbit around set camera target
Middle mouse scroll up and down to zoom in and out
Hold middle mouse and mouse input to drag up, down, left and right
I’ve already looked at the mouseOrbit script to get some of these controls started, but I was wondering if there was any other documentation available or if the code for the editor camera was publicly available somewhere.
There is an asset, you would have to search which will snap your editor view to the camera view. Not sure it is dynamic, as in follow the the cam if its transform etc is altered.
That is an interesting tool, but not quite what I am looking for.
What I am trying to find is a script that will allow the player to transform the position and rotation of the camera in game in the same way that I can manipulate the scene view in the editor. So far I have found a script in the wiki that allows me to add zoom and orbit functionality to the camera object.
