help with mouse scrolling
What im trying to do is when im dragging an object if i roll the scrollwheel up i want the object to go farther away and when i roll the scroll wheel down i want the object to come closer while im still dragging it. Here is my script:
function OnMouseDown () { var screenPos = Camera.main.WorldToScreenPoint(transform.position); var offset = transform.position - Camera.main.ScreenToWorldPoint(Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPos.z));
while (Input.GetMouseButton(0)) { var curScreenPos = Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPos.z); var curPos = Camera.main.ScreenToWorldPoint(curScreenPos) + offset; transform.position = curPos; yield;
if(Input.GetAxis("Scrollwheel"))
{
WHAT DO I PUT HERE
transform.position= ????
}
} }
Can you tell me the code to put inside of that if statement to be able to read the mouse wheel up and down movements?
To get the input from the scrollwheel use Input.GetAxis ("Mouse ScrollWheel").
This is a default axis and is defined in the Input Manager.
If you want to zoom in or out you could change camera.fieldOfView:
var zoomfactor : float = 10.0;
camera.fieldOfView += Input.GetAxis ("Mouse ScrollWheel") * zoomfactor;
(You should tweak the zoomfactor to get the best results.)
Edit:
var scrollfactor : float = 10.0;
transform.position.z += Input.GetAxis ("Mouse ScrollWheel") * scrollfactor;
(And of course tweak the scrollfactor to get the best results)
Im not trying to zoom the camera im trying to move the trasform.position.z of an object im dragging closer or further away from the player using the scroll wheel. do you know how to do that?
I don't know how your game's designed, so this might not be an issue, but what if your player isn't looking along the global z-axis? Then changing the transform's z-axis won't move the object away from, or closer to the player.
