zinx_app_demo/mmo_game/core/aoi.go:136–141

GetGIDByPos Get the corresponding grid ID by horizontal and vertical coordinates 通过横纵坐标获取对应的格子ID

(x, y float32)

// GetGIDByPos Get the corresponding grid ID by horizontal and vertical coordinates
// 通过横纵坐标获取对应的格子ID
func (m *AOIManager) GetGIDByPos(x, y float32) int {
	gx := (int(x) - m.MinX) / m.grIDWIDth()
	gy := (int(y) - m.MinY) / m.grIDLength()

	return gy*m.CntsX + gx
}

// GetPIDsByPos Get all PlayerIDs within the surrounding nine grids by horizontal and vertical coordinates
// 通过横纵坐标得到周边九宫格内的全部PlayerIDs
