Help with timers.

cmannen 11 Sep 2015 12:01

I thought of a game where you would press a key a special amount of times as fast as possible. Faster clicks = more points. Each time you press said key, it plays a new animation, and it isn't unlimited, therefor there has to be some sort of timer that ticks down.

My idea is that you have the timer, and you have a specified amount of base points, then you multiply the remaining time with the base points.

So how are we going to do all this?

//Timer                                                       (counts down from... Say 7 seconds)
...
7-A->B                                                        (A is the time it took)
100*B->C
Output(y,x,"You scored: ")
Output(y+1,x,C)

Only thing missing is the timer now. *Also, I'm using the TI-82, if I'm correct it doesn't have a built in timer function.

Question is if it's possible to have a timer working in the background of the clicking process.

Well, I'm not too familiar with the Ti-82, but I suppose the clicking happens in a loop, right? If so, couldn't you just include a timer in that loop?

Well, what kind of timer?
Since I have:

Pause                              (Pressing enter continues the animation)
Animation #1
Pause
Animation #2
Pause
Animation #3
Pause
Animation #4

I'm not using a loop function, so how do I get it to work? Perhaps I add a timer between each animation, and if it's too long I'd put it in a secondary program, say program X.

Pause
Program X
Time left ->A
Animation #1
Pause
Program X
Time left ->B
Animation #2
Pause
Program X
Time left ->C
Animation #3

etc.

Then subprogram X needs to be stopped with Enter, so it needs a GetKey function to stop it at the current time, and send the time as a variable to the letter A,B,C,D… right? I really have no idea whatsoever how to make that. I hardly can make a basic clock. Unfortunately the TI-82 lacks the direct clock function.

It's impossible to time anything when Paused, or indeed to time any code in the background, without the 84+ series' timer function. You'll need to be slightly clever about it: try a For( loop that has an If statement inside which checks whether a key has been pressed, and if so displays the animation and records the keypress. The number of times the For( has looped will function as the timer.

I used my second idea, recording the time between each keypress individually and then summing them up. It works!
