Translate Point By Vector3 And Angle
I am writing a camera script for a RTS game. Currently it can orbit and zoom around a point. The target point. I want the player to be able to 'pan' around by moving the mouse onscreen. The mouse movements on screen will then be used to translate this target point.
Currently I can get the vector from the users screen from where the first click (the new origin).
if(Input.GetMouseButtonDown(0)) {
dragOrigin = Input.mousePosition;
}
Vector3 pos = Camera.main.ScreenToViewportPoint(Input.mousePosition - dragOrigin);
Vector3 move = new Vector3(-pos.x * 2.0F, 0, -pos.y * 2.0F);
How can I translate the current point
Vector3 target = (0.0F, 0.0F, 0.0F);
Taking into account the rotation my camera is angled at, say 30 degrees. This is only for the X and Z coords. The Y is always 0.0F in this context.
If you make your target point the rotated object, you can use Transform.TransformDirection to move it relatively to its rotation.
The target point isn't a transform. Just a Vector3. Im wating to take the vector3 and translate it by a vector created from how the user has dragged their mouse. $$anonymous$$G - $$anonymous$$y target pos = (30.2F, 0.0F, 15.0F) mousemove pos = (1.5F, 0.0F, 2.5F); camera is 30 deg on XZ plane new target pos = (X, Y, Z);
$$anonymous$$ake it a transform then, it saves you a lot of work and you'll get much cleaner code.
Thanks a lot :-) took a bit of fiddling but it works perfectly now
