我有一个生成该错误的文件
"Block" is not a class or a namespace name
在线上
typedef Block::point point;
不过，我敢肯定，这就是我一直都创建并执行#included下面的文件类
'texture.h'。
#pragma once
#include "Block.h"
#include <iostream>
#include <vector>
#include <GL/glut.h>
#include "lodepng.h"
using namespace std;
typedef Block::point point;
class Texture
{
public:
Texture(int width, int height, string filename);//initialises our texture and loads its pixeldata into a buffer
Texture(void);
~Texture(void);
void draw(point centerPoint, point dimensions);
unsigned int w;//width of our imagefile
unsigned int h;
GLuint texID;//the ID we will give OGL for this particular texture.
private:
vector<unsigned char> image;
void texGLInit();
};
也只是良好的措施，这里是有问题的block.h文件。
#pragma once
#include <GL/glut.h>
#include <math.h>
#include <stdio.h>
#include <stdlib.h>
#include "Texture.h"
class Block
{
public:
struct point
{
GLfloat x, y;
};
enum State {STATIC, FALLING, SELECTED};
enum Colour {RED, BLUE, PURPLE, GREEN, YELLOW, DEAD};
Block(void);
~Block(void);
Block(int gridPosX, int gridPosY, point offset);
point gridPos;//the blocks designated position in the 8x8 array
point centerPos;//the blocks coordinates for the actual purpose of drawing
State blockState;//the state of the block
Colour blockColour;//the colour of the block
void move();//checks whether the block is in a falling state and moves it appropriately
void drawBlock();//no need to include the drawing coords as parameters. the block knows where it should be. The grid will simply tell it to draw itself.
private:
void fall();//decrements the blocks position
void assignRandomColour();//assigns a random colour to the block dependant upon its' texture
void generateWorldPos();//gets our block a center position, for us to later to use to draw it.
//the above function will also inherently define the size of each cell in the grid. I'm thinking each
//cell should be 40x40. So each cell will be offset initially by 20px by 20px.
point gridOffset;
};
我不知道，为什么我可以得到这个错误对于确实存在的类。 提前致谢。
