我在使用allegro进行编程方面相当新,我想改变我的程序的背景颜色,使其比黑色更令人愉快哈哈 :)可以帮助一些人吗?
仅供参考我正在做什么
#include <allegro.h>
BITMAP* buffer;
BITMAP* bmp;
int cursor_x = 20;
int cursor_y = 20;
int getMouseInfo(){
if(mouse_b & 1){
cursor_x = mouse_x;
cursor_y = mouse_y;
return 1;
}
return 0;
}
void updateScreen(){
show_mouse(NULL);
circlefill ( buffer, cursor_x, cursor_y, 60, makecol( 0, 255 , 0));
draw_sprite( screen, buffer, 0, 0);
}
int main(){
allegro_init();
install_mouse();
install_keyboard();
set_color_depth(16);
set_gfx_mode( GFX_AUTODETECT, 640, 480, 0, 0);
rectfill (
buffer = create_bitmap( 640, 480);
show_mouse(screen);
while( !key[KEY_ESC])
{
int switcher=1;
while(getMouseInfo())
{
updateScreen();
if(getMouseInfo()==0) switcher=0;
}
if(switcher==0) show_mouse(screen);
}
return 0;
}
END_OF_MAIN();
答案 0 :(得分:2)
要创建背景位图,请尝试以下方法:
/* Make a bitmap in RAM. */
BITMAP *bmp = create_bitmap(SCR_X, SCR_Y);
然后尝试将bmp清除为某种不同的颜色:
/* Clear the screen to red. */ clear_to_color(bmp, makecol(255, 0, 0));
或者这个从文件中加载位图:
bmp = load_bitmap("image.pcx", palette);
然后你只需要在屏幕上显示这个位图 - 就像这样:
/* Blit bmp on the screen. */
blit(bmp, screen, 0, 0, 0, 0, bmp->w, bmp->h);

绘制一个屏幕大小的矩形,它是您想要背景的颜色。或者只需使用clear_bitmap
清除屏幕。

#include <iostream>

{
cout<<" In the world were gamers play MINECRAFT, where they creating everithing they can emagine ...\n";
cin.get();
return 0;
