Embodiment Construction

[0048] In order to make the present invention more comprehensible, a preferred embodiment is now described in detail with accompanying drawings as follows.

[0049] The method of the present invention is suitable for scenes where the camera is fixed and the depth of field does not change much. On the basis of the parallel dragging method of the camera viewing surface, an independent plane is introduced, which is equivalent to a plane between other objects in the scene and the camera. A piece of white paper faces the camera to cover other objects, distinguishing the two, and then through the algorithm, the object can be dragged at the mouse pointer in the screen space, and not on a separate plane in the world coordinates. Other objects coincide.

[0050] Such as Figure 1 to Figure 5 Shown, in a kind of Unity3D scene of the present invention, the method for dragging by the surface of mouse to object comprises the following steps:

[0051] Step 1. Create a plane game object (P...

Abstract

The present invention provides a method for dragging a mouse to an object by surface in a Unity3D scene, comprising: 1. creating a plane game object; 2. placing the plane game object between the plane where the scene is located and the camera; 3. starting to drag When dragging, use the built-in API of Unity to obtain the screen coordinates where the mouse is located, and obtain the ray from the camera passing through the screen coordinates in the 3D world coordinates; 4. Determine the intersection point of the extension line of the ray and the plane game object as the target position, and calculate the target position; 5. Transform the position of the dragged object into the target position, then the dragged object will be on the plane game object and under the mouse pointer, so as to realize the dragging process, as long as the plane game object is not in the scene If other objects intersect, the dragged object will not coincide with other objects. The present invention also provides a computer-readable storage medium, which can prevent the dragged object from overlapping with other objects in the scene after being dragged.

Description

technical field [0001] The invention relates to the technical field of Unity3D, in particular to a surface-based dragging method and medium of a mouse on an object in a Unity3D scene. Background technique [0002] Currently, when dragging a 3D object in a Unity3D scene, the object is generally parallel to the viewing surface of the camera. This will cause the dragged object to easily overlap with other objects in the scene during the dragging process. After overlapping, bad visual effects will occur. Affecting the user experience is something that developers do not want consumers to see. In order to avoid the occurrence of coincidence phenomenon, generally use two methods when using the Unity engine to drag and drop objects: [0003] 1. Dragging method parallel to the camera’s viewing surface: the dragged object is dragged on a dragging surface that is parallel to the camera’s viewing surface and separated by a distance x from the camera’s viewing surface. In order to ensur...
