The latest tank battle 2022 full development notes-1

One 、 Project introduction

Tanks war 1990 As a classic stand-alone game , yes 80 after 、90 Good memories after , It's also C/C++ A must for beginners .

But tanks 1990, The game screen is too simple . We are now on tanks 1990 Make a new upgrade , Use C Language , Build the latest tank 2022！ The effect of the game is as follows ：

Four 、 Create project

Use VS2019, Or other versions VS, Create a new project , Select an empty project template .

5、 ... and 、 Realize the battlefield layout of tank war

 5.1  Import game resources

Put resource directory res Import project directory .

 

5.2 Realize the game background

  add to main.cpp

#include <stdio.h>
#include <graphics.h>
 
IMAGE imgBG;
 
void init() {
	initgraph(1300, 900);
	loadimage(&imgBG, "res/bg1.png");
}
 
void updataMap() {
	putimage(0, 0, &imgBG); // Update the game background 
}
 
 
int main(void) {
	init();
 
	updataMap();
 
	system("pause");
	return 0;
}

 

5.3 Realize game map

First add the most basic map elements , Add other elements later , Such as jungle cover 、 The river 、 Shields and other props .

  Define enumeration types , To represent various map elements .

enum {
	EMPTY,       // clearing 
	TU_WALL,     // The earth wall 
	GANG_WALL,  // Steel wall 
	MY_HOME,    // Our commander    
	ENEMY_HOME, // The opposing commander 
	UNIT_COUNT
};

 

Define the image array imgUnits To represent each map element

IMAGE  imgUnits[UNIT_COUNT];

stay init In the initialization function , Load map elements .

imgUnits[EMPTY] = NULL;
loadimage(&imgUnits[TU_WALL], "res/wall1.png");
loadimage(&imgUnits[GANG_WALL], "res/wall2.png");
loadimage(&imgUnits[MY_HOME], "res/pj2.png");
loadimage(&imgUnits[ENEMY_HOME], "res/wukelan2.png");

Use a two-dimensional array to represent the map layout , The subsequent optimization is to use multiple files to represent the map data of each level .

 

   int map[18][26] = {
        { 0,0,1,1,0,0,1,1,0,0,0,1,4,0,1,0,0,0,1,1,0,0,1,1,0,0 },
        { 0,0,1,1,0,0,1,1,0,0,0,1,0,0,1,0,0,0,1,1,0,0,1,1,0,0 },
        { 0,0,1,1,0,0,1,1,0,0,0,1,1,1,1,0,0,0,1,1,0,0,1,1,0,0 },
        { 0,0,0,0,0,0,0,0,0,0,1,1,0,0,1,1,0,0,0,0,0,0,0,0,0,0 },
        { 0,0,0,0,0,0,0,0,0,0,1,1,0,0,1,1,0,0,0,0,0,0,0,0,0,0 },
        { 1,1,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,1,1,1,1,0,0,1,1 },
        { 2,2,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,1,1,1,1,0,0,2,2 },
        { 0,0,0,0,0,0,0,0,0,0,1,1,0,0,1,1,0,0,0,0,0,0,0,0,0,0 },
        { 0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0 },
        { 0,0,1,1,0,0,1,1,0,0,1,1,1,1,1,1,0,0,1,1,0,0,1,1,0,0 },
        { 0,0,1,1,0,0,1,1,0,0,1,1,0,0,1,1,0,0,1,1,0,0,1,1,0,0 },
        { 0,0,1,1,0,0,1,1,0,0,1,1,0,0,1,1,0,0,1,1,0,0,1,1,0,0 },
        { 0,0,1,1,0,0,1,1,0,0,1,1,0,0,1,1,0,0,1,1,0,0,1,1,0,0 },
        { 0,0,1,1,0,0,1,1,0,0,0,0,0,0,0,0,0,0,1,1,0,0,1,1,0,0 },
        { 0,0,1,1,0,0,1,1,0,0,0,0,0,0,0,0,0,0,1,1,0,0,1,1,0,0 },
        { 0,0,1,1,0,0,1,1,0,0,0,1,1,1,1,0,0,0,1,1,0,0,1,1,0,0 },
        { 0,0,0,0,0,0,0,0,0,0,0,1,3,0,1,0,0,0,0,0,0,0,0,0,0,0 },
        { 0,0,0,0,0,0,0,0,0,0,0,1,0,0,1,0,0,0,0,0,0,0,0,0,0,0 }
    };

According to the two-dimensional array map data , stay updataMap Function to update map data .

  

     for (int i = 0; i < 18; i++) {
            for (int j = 0; j < 26; j++) {
                putimage(j * 50, i * 50, &imgUnits[map[i][j]]);
            }
        }

Run the program , View the game map effect ：

 

 5.4 Realize the transparent background of the command post and import customized tools.h and tools.cpp

1） Import custom tools.h and tools.cpp
2） stay main.cpp Add

#include "tools.h"

3） Modify the code

//putimage(j * 50, i * 50, &imgUnits[map[i][j]]);
putimagePNG(j * 50, i * 50, &imgUnits[map[i][j]]);

The test results are as follows :

   next step , We will create tanks on both sides .
