我在快板上有一个窗口,当点击顶部的X按钮时,它应该关闭。我有所有必要的代码可以使用,但它不会。
要初始化显示我有:
display = al_create_display(dwidth, dheight);
if (!display){
error.message("Fatal Error", "ERROR:", "DISPLAY HAS FAILED TO BE CREATED");
}
要初始化事件队列,我有:
ALLEGRO_EVENT_QUEUE *event_queue = NULL;
event_queue = al_create_event_queue();
if (!event_queue){
error.message("Fatal Error", "ERROR:", "EVENT QUEUE HAS FAILED TO BE CREATED");
}
al_register_event_source(event_queue, al_get_display_event_source(display));
为了响应输入并使用或关闭窗口渲染,我有:
al_start_timer(tick);
while (true)
{
//handle input and timer
ALLEGRO_EVENT ev;
al_wait_for_event(event_queue, &ev);
if (ev.type = ALLEGRO_EVENT_TIMER){
redraw = true;
//put all fps dependant function here
}
else if (ev.type == ALLEGRO_EVENT_DISPLAY_CLOSE){
break;
}
if (redraw && al_is_event_queue_empty(event_queue)) {
//FPS independant functions go here
al_flip_display();
al_clear_to_color(al_map_rgb(255, 255, 255));
redraw = false;
}
}
答案 0 :(得分:1)
我认为您需要更改一行:
else if (ev.type == ALLEGRO_EVENT_KEY_DOWN){
到
else if (ev.type == ALLEGRO_EVENT_DISPLAY_CLOSE){
