Hi guys,
I am trying to create digital clock in the game which is going to be stopped, and will pass time only if certain actions take place. That means the usual "DateTime" global variable is not an option.
Example:
- Time: 10:00
- You click on Hotspot
- Time: 10:05
The premise is simple, but I don't know how to make a function that will recognize the time logic. For example if I have 11:59, and you click on a hotspot, I want to add +1 second, how do I make the variable go to 12:00, instead of 11:60.
Because I am able to just add +1 to the int value.
Store the "total minutes" value in a global variable for easier addition and subtraction, but when displaying on a clock convert from "total minutes" to hours and minutes.
int hours = total_minutes / 60;
int minutes = total_minutes - (hours * 60);
EDIT: Or, if you need to have a second-precision, then store "total_seconds", and convert from them:
int hours = total_seconds / 3600;
int minutes = (total_seconds - (hours * 3600)) / 60;
int seconds = total_seconds - (hours * 3600) - (minutes * 60);
PS. The above idea is valid, but I could make some math mistake, so need to double check that above works right.
UPD: In overall, in the software design, when you have a similar situation, the idea is to separate the data and the visual representation. The data is chosen in such way that makes it easier to store and change. The visual representation may be anything; or there may even be several different representations, all converted from same data.
Yup, what CW says (though he could have used % instead of all the multiplications and subtractions). I'll just add that if you need the hours to wrap around as well, you'll have to add a further step. Exactly how to do that depends on the clock you use:
-On a 24-hour clock it's easy. You go from 23:59 to 00:00 simply by doing % 24:
int days = total_minutes / 1440; // 1440 = 60*24
int hours = (total_minutes / 60) % 24;
(Or adjust as necessary if you measure the time in seconds. The days variable isn't used for the clock, of course, but you can use it for a calendar or internally in your game logic.)
-On a 12-hour clock with AM/PM (where you go from 11:59 AM to 12:00 PM), you need to convert the 24-hour time by doing % 12, figuring out if it's AM or PM, and displaying 12 if the number is 0. I would probably do this as a separate step based on a 24-hour hours variable:
int amOrPm = hours / 12; // 0 if AM, 1 if PM
int displayHours = hours % 12;
if(displayHours == 0)
displayHours = 12;
Thanks guys! Appreciate your help!
I have a new problem though... When I want to change the global variable during a dialogue, nothing happens. Only after I leave the entire dialogue. So basically, I need to change the variable every time you click on a dialogue option to -10. What happens, is that the variable stays the same, and only after I leave the dialogue it calculates all the clicks I did during the dialogue, so it goes like -50.
In other words, it calculates my Time = Time -10; , but it doesn't print the values out when inside a dialogue.
My code is simple like this.
@1
Time = Time - 10;
You: So what do we have here?
NEVERMIND guys, I solved it like a second after I made the post.
I original had the Label1.Text = String.Format("%02d", Time); in repeatedly execute, instead of repeatedly execute ALWAYS :)
Since the label text needs to be updated only after the time has changed, you can write a function:
function MoveClock(int by) {
Time += by;
Label1.Text = String.Format("%02d", Time);
}
Now use
MoveClock(-10);wherever you want.
You can also put the display logic inside the function obviously.

Note also that you may let "repeatedly execute" run during dialogs too, if you enable this in General Settings.
