Posted on by Dakol

Hi all,

The title pretty much says it all - i got a button on screen1 that i want to start a timer on screen 2 (without navigating to screen2)

I'm aware both screens have to be active at the same time for it to work, but i cant figure out the combination of Set and global settings.

All input greatly appreciated!

Thanks

Hi

You can achieve this by using a global variable to store the start time of the timer other screens.

On Screen 1, add a button and set its OnSelect property to UpdateContext({StartTimer: true}). This will set the value of the global variable to true when the button is clicked.

On Screen 2, set the AutoStart property of the Timer control to StartTimer. This will start the timer when the value of the global variable is true.

Optionally, you can add actions to perform when the timer finishes running by setting the OnTimerEnd property of the Timer control.

Thanks!

It should be as simple as setting a Boolean variable with your button, and then using that variable in the Start property of your timer.

Here's an extremely simple example:

Controls used: Button, Timer, Label (to show the timer value)

This is the OnSelect property of my button:
Reset(Timer1); Set(var_StartTimer, false); Set(var_StartTimer, true);

I'm resetting the Timer1 control and my var_StartTime global variable in the same place for ease of testing. In your app you may only have the last command, Set(someVariable, true).

I left the timer unchanged, except for its Start property, I set it to the variable changed by Button1:

Hope that helps!

Clearing up Rajkumar's answer in case anyone reads it later.
Context variables are scoped to the screen (local variables), so the other screens won't be aware of it and you will get a formula-level error.

The AutoStart property of a timer controls whether the timer begins automatically when the screen becomes visible.

You could set the OnHidden property of the screen where the timer is as Set(var_StartTimer, var_StartTimerfromButton) and set the OnSelect property of the button on the other screen with Set(var_StartTimerfromButton, true) and then for the last you set the autostart property of the timer as var_StartTimer.

This should work, but first, you must go through the screen where the timer is then go to the screen where the button is and click it. If you must go through the screen where the timer is in, its better to place the timer on the home screen, because you always and must see the home screen first as you play the app.

This is the best workaround that I could suggest to you, I don't know if it help though.
You could ask me if you don't understand this instruction.
