How to Create many instances of a Timeline

johnbonz1 · October 2022

In my previous posts I created a Stop watch/Countdown timer. I want to create multiple instances of the timelines required to run the stopwatch/countdown. So if I am on panel 1 and I want to create a countdown for 1 minute, and then wife is using another panel, 2, and she wants to have a countdown to boil eggs for 10 minutes.
So I am using 8400 - panel 1 and she is using a 8400 panel 2, so I dont think u can create a Array of Timelines in Netlinx.
so you would think you can do this:

TIMELINE_EVENT[TL_StopWatch[nPNL] // capture all events for Timeline TL_StopWatch
{
.
.
.
but instead I have to create a Timeline for every panel like this:

Panel 1 Timeline:

TIMELINE_EVENT[TL_StopWatch_1] // capture all events for Timeline TL_StopWatch_1
{

...

Panel 2 TimeLine:

TIMELINE_EVENT[TL_StopWatch_2] // capture all events for Timeline TL_StopWatch_2
{
and so on. If I have 50 panels I would need to create 50 seperate Timlines for each panel. This doesnt seems right as I should be able to create an Array of timelines based on the panel but one entry in the timeline section.

Anyone ever run into this?

Stack the TIMELINE_EVENTS and then use the timeline.id event data member to map back to the timeline you care about

    long TL_TIME[] = {1000};


define_function integer getLongArrayIndex(long item, long array[]) {
    stack_var integer i;

    for(i = length_array(array); i; i--) {
    if(item == array[i]) {
        break;
    }
    }

    return i;
}
