Hi Mark,

All items are visible by default in a particular storyboard.
Therefore in order to stop them appearing, you will need to go through all the items you wish to be hidden
for that particular data change event and set them all to hidden.

Thinking about this a little more...

Are there any plans to add functionality to the API to allow the API to trigger parts of a GT title to be animated?

I want to show a time for an competitor as they finish and overlay it on their lane. We don't know the order they will finish in advance so can't story board it. I can get the events from the timing system via a serial port, I have written code in the past to update numeric score boards from this. Currently I could modify this code to send API commands to vmix to update the names and times but not to animate the individual layers.

I suspect you are busy getting ready for the launch of v22, so I best go and add this to the feature request forum.

Thanks for the reply and for posting the API command, I am sure that will be useful in the future :-), just not for this particular problem :-(

The reason I don't think that would work is I am trying to get the times to slide in as the swimmer hits the end of the pool and there is not enough pages to cover all the combinations of who came 1st,2nd,3rd etc and make them appear in the right order.

Dusting off my maths...

With 1 lane there is only 1 possibility of who came first
With 2 lanes you could get 1,2 or 2,1 = 2 combinations
with 3 lanes you could get 1,2,3 or 1,3,2 or 2,1,3 or 2,3,1 or 3,1,2 or 3,2,1 = 6 combinations.

this looks like a factorial expression to me, so the number of combinations gets big very quickly. 6, 8 and 10 lane swimming pools are common...

Lanes Combinations
1 1
2 2
3 6
4 24
5 120
6 720
7 5040
8 40320
9 362880
10 3628800

So even if GT had unlimited 'pages' it rapidly becomes unpractical to enter all the combinations ;-)

So, until the Vmix/GT API allows us to trigger particular events I have had a look at another possible solution which is looking quite promising.

I have constructed a html web page with css animations. I have added javascript and websockets to this to trigger the animations. The html page is then added to Vmix as a browser source and shown as an overlay. I am currently using a python websockets server which has the benefit that I can also decode the serial data from the electronic timekeeping system in python and update the time and trigger the animations to occur at the correct moment.

So far this working well, I don't have the serial data stream decoded in python yet (but I have written the same code in C before for an LED score board I built) so I am using buttons on another webpage to trigger the events. Importantly the animation is looking smooth and responsive. I will try post a video later.
