The SnapToGrid method in the Vector3 struct is used to adjust the components of a vector to align with a specified grid size. This method is useful for snapping a vector to a grid, which is often needed in scenarios like game development or 3D modeling where objects need to be aligned to a grid for consistency or aesthetic purposes.
To use the SnapToGrid method, you need to specify the grid size and which components (x, y, z) should be snapped. The method returns a new Vector3 instance with the specified components snapped to the nearest grid point.
Parameters:
gridSize (System.Single): The size of the grid to snap to. This value determines the spacing between grid points.sx (System.Boolean): If true, the x component of the vector will be snapped to the grid.sy (System.Boolean): If true, the y component of the vector will be snapped to the grid.sz (System.Boolean): If true, the z component of the vector will be snapped to the grid.// Example of using SnapToGrid Vector3 position = new Vector3(3.7f, 4.2f, 5.9f); float gridSize = 1.0f; Vector3 snappedPosition = position.SnapToGrid(gridSize, true, true, true); // snappedPosition will be (4.0f, 4.0f, 6.0f)
