在谷歌搜索之后,我发现我在“如果”之前遗漏了一些东西。据我所知没有。说真的,我在这里错过了什么?我在第 44 行有这个错误,我清楚地看到了所有的括号和分号。

#include "Entity.h"
#include "string.h"
#include "surface.h"
#include "stdlib.h"
#include "template.h"
#include "SDL.h"
#include "game.h"
#include "Ghosts.h"
#include "Character.h"
#include "Tile.h"

using namespace Tmpl8;

Surface* Map = new Surface("assets/map.png");
Surface* Spook = new Surface("assets/ghost.png");
Surface* Player = new Surface("assets/char.png");
Sprite* Play = 0;
Invader Invaders[55];
Character c;

Tile* myTile = new Tile(96,96); //Define new tile.
Tile* tileArray[3000/96][3280/96]; //Define size total tiles.

TileProperties myTileset[2] = {
    {true,  0,  0}, //Tile 0 = solid wall, graphics at 0,0
    {true, 96,  0} //Tile 1 = open space, graphics at 96,0
};

const int MAP_WD = 5;
const int MAP_HT = 5;

int map[MAP_WD * MAP_HT] = {
    1,1,1,1,1,
    1,1,0,0,1,
    1,0,0,0,1,
    1,0,1,0,1,
    1,1,1,1,1
};

const TileProperties& GetTile(int x, int y) {
    return myTileset[map[(y*MAP_HT) + x]];
}

if (GetTile(c.Xpos, c.Ypos).Wall) { //Here's the trouble.

}

错误:

“如果”在全局范围内。你必须把它放在一个方法/函数中。

您必须简单地将其if放入某个函数中。在 C/C++ 中,除了变量/数据结构/函数等之外,编写一些代码。函数之外的声明是非法的。
