Left Click and Pan
I want to write a script that allows the player to hold left click and pan the camera.
It should looks something like this:
OnMouseDown if mouse moves left camera pans to the right (locally I think)
Also middle mouse wheel to zoom.
And middle mouse button to rotate.
How would I go about accomplishing this in JavaScript?
To answer your first question, I would store the coordinates of where your mouse first "clicked". Then, make a variable to determine that you are now dragging with the following psuedo-code.
Note: This is not a copy/paste affair, I'm just explaining my thought process.
var dragging : boolean; var mouseDownPos : Vector3;
if(OnMouseDown){ dragging = true; mouseDownPos = Mouse's position when you clicked; }
Now that you're dragging, continually grab the current position of the mouse.
var mouseDragPos : Vector3;
if(dragging)
mouseDragPos = Mouse's position as you are dragging;
Then, subtract the two and move the camera's transform accordingly.
camera.Main = camera.Main.transform.position + ( mouseDownPos - mouseDragPos );
thanks a lot you have invigorated my logic, and helped me answer all of my questions. I realized zoo$$anonymous$$g with the mouse wheel is just moving the camera locally on the x axis. And of course my middle mouse click is pretty much what you showed me with the panning.
This assumes the script is running on the camera...
// ***** PANNING ***** // Hold Right Mouse Button to pan the screen in a direction if(Input.GetButtonDown("MouseRight")) { print ("Panning..."); viewScreenPanning = true; viewScreenOldMouseX = Input.mousePosition.x; viewScreenOldMouseY = Input.mousePosition.y; }
// If panning, find the angle to pan based on camera angle not screen if(viewScreenPanning==true) { if(Input.GetButtonUp("MouseRight")) { viewScreenPanning = false; } viewScreenPanVector = transform.TransformPoint(Vector3(-(viewScreenOldMouseX - Input.mousePosition.x) / viewScreenPanSpeed, 0.0, -(viewScreenOldMouseY - Input.mousePosition.y) / viewScreenPanSpeed)); // since we use a quick and dirty transform, reset the camera height to what it was viewScreenPanVector.y = viewScreenZoomHeight; transform.position = viewScreenPanVector; }
