Escape delay with a button in a game - c

Question

I have a problem with a piece of code for a game. I would like to know, how to break the time delay if I press the button.
List of files
At the end, the game writes your end score on the LCD for 10 seconds. And goes back to the wait for start. I want to keep that as it is - the only thing that I want to include is that if I press the button within those 10 seconds I want it to go immediately back to the wait for start.
Function code is here
void DrawGameScore()
{ //&RFONT_8X12 &RFONT_16X26
//char key;
//key = KBD_GetKey();
char txt[10];
UG_FontSelect(&RFONT_16X26);
UG_SetForecolor(C_WHITE);
switch (level){
case 1:
UG_PutString(60,130,"Peasant Score:");
sprintf(txt,"%d",score);
UG_PutString(120,160,txt);
_delay_ms(10000);
break;
case 2:
UG_PutString(60,130,"Knight Score:");
sprintf(txt,"%d",score);
UG_PutString(120,160,txt);
_delay_ms(10000);
break;
case 3:
UG_PutString(60,130,"Queen Score:");
sprintf(txt,"%d",score);
UG_PutString(120,160,txt);
_delay_ms(10000);
break;
case 4:
UG_PutString(60,130,"King Score:");
sprintf(txt,"%d",score);
UG_PutString(120,160,txt);
_delay_ms(10000);
break;
case 5:
UG_PutString(60,130,"God Score:");
sprintf(txt,"%d",score);
UG_PutString(120,160,txt);
_delay_ms(10000);
break;
}
//UG_PutString(60,130,"Final Score:");
//sprintf(txt,"%d",score);
//UG_PutString(120,160,txt);
//_delay_ms(1000);
}
When the game is over this function draws your score based on your level. In this next function i am calling drawgamescore function, which is in dsip_end_score makro.
int EndOfGame()
{
char key;
//static int state;
int result = 1;
key = KBD_GetKey();
display_msg = DSIP_END_SCORE;
if (key == BTN_OK){
//display_msg = DISP_REFRESH_ALL;
//display_msg = DSIP_END_SCORE;
return result;
}
return result;
}
Here is the main game function
void Game()
{
static int state;
int result;
switch (state)
{
case 1: //waiting for the game start
result = WaitForStart();
if (result == 1) state++;
break;
case 2: //Play the game
result = PlayTheGame();
if (result == 1) state++;
break;
case 3: //Display the score
result = EndOfGame();
if (result == 1) state=0;
break;
default: //0 or unknown value: reset the game
state = 1;
break;
}
}
Thanks.
I tried
int EndOfGame()
{
char key;
static int state;
int result = 1;
key = KBD_GetKey();
display_msg = DSIP_END_SCORE;
if (key == BTN_OK){
//display_msg = DISP_REFRESH_ALL;
//display_msg = DSIP_END_SCORE;
return result;
}
return result;
}
/*
display_msg = DSIP_END_SCORE;
if (key != 0){
switch (key)
{
case BTN_OK:
return result;
break;
}
}
*/
/*
switch (state)
{
case 0:
display_msg = DSIP_END_SCORE;
state++;
break;
case 1:
key = KBD_GetKey();
if (key != 0){
switch (key)
{
case BTN_OK:
return result;
break;
}
break;
}
}
return result;
*/
//display_msg = DISP_REFRESH_ALL;
//display_msg = DSIP_END_SCORE;
//return result;
/*
char key;
int result=0;
//static int state;
key = KBD_GetKey();
if (KBD_isKeyStatePressed(BTN_OK))
{
display_msg = DSIP_END_SCORE;
result = 1;
} else {
result = 1;
}
//return result;
*/
/*
switch (state){
case 0:
KBD_flush(); //empty buffer
//display_msg = DISP_REFRESH_ALL;
display_msg = DSIP_END_SCORE;
return result;
state++;
break;
case 1:
key = KBD_GetKey(); //kbd read dela background services
if (key == BTN_OK){
//display_msg = DISP_REFRESH_ALL;
display_msg = DSIP_END_SCORE;
return result;
break;
}
break;
}
return result;
*/
/*
key = KBD_GetKey();
if (key == BTN_OK) {
//display_msg = DISP_REFRESH_ALL;
return result;
}else{
display_msg = DISP_REFRESH_ALL;
display_msg = DSIP_END_SCORE;
//TODO: write the program
return result;
}*/

I found a solution!
Here is the code if anyone is interested.
int EndOfGame()
{
int result = 0;
char key;
static uint32_t timeStamp;
static int state = 0;
display_msg = DISP_REFRESH_ALL;
switch (state)
{
case 0: //Show end score
display_msg = DSIP_END_SCORE;
timeStamp = GetSysTick();
state++;
break;
case 1: //read keys after 2 seconds
if (Has_X_MillisecondsPassed(2000, &timeStamp)
{
state++;
KBD_flush();
break;
}
break;
case 2:
key = KBD_GetKey();
if (key != 0)
{
switch (key)
{
case BTN_OK:
state = 0;
result = 1;
break;
}
}
//finish after 10 seconds
if (Has_X_MillisecondsPassed(10000, &timeStamp))
{
result = 1;
state = 0;
break;
}
break;
}
return result;
}
If you want to know about the
Has_X_millisecondsPassed();
function you are welcome to see it in systime.c in the File list hyperlink in the question above. For the reference i'm using AtMega328pb microcontroller.
