Anyone know if there's a way to generate URL's for SoundCloud tracks that specify a start time for the song? I'm looking for a way to force playback of streams at a certain time in the stream without having to do any processing on my end via the API.
As #bsz correctly noticed, we have released a way of specifying start time on the sound when linking to it, append #t=12s to the sound's URL to start it at 12th second, etc.
If the audio is long enough, you can use (e.g.) #t=2h10m12s.
They seem to have added a #t option but not sure if you can also give an stop time:

You can also specify a start time one minute or over by appending
#XmXs
If you want a time right on the minute mark (e.g. 3:00), include 0 seconds (0s) in the time code (i.e. 3m0s), or else the start time will be ignored. It does not appear to support a start time over an hour.

I would like to give the user a button that allows them to skip ahead 1 hour in the simulation and then continue running the model if play is clicked. The code below allows the user to skip ahead an hour, however they are unable to resume the simulation when play is clicked.
double nextHour = time() + 60;
pauseSimulation();
getEngine().runFast(nextHour); //Runs the model to the next hour when button is clicked
Any help much appreciated.
Try adding runSimulation() after the last line. But probably, that does not work. In that case:
Create a dynamic event (not the normal event) with the line runSimulation() in its action code.
In the button code, before the runFast... line, write create_MyDynamicEvent(1, HOUR). This will trigger the even 1 hour later and unpause the model.
AnyLogic Support suggested the following solution, which I have used:
Unfortunately, Ben's suggestion didn't didn't work; it seems to cause an issue when pauseSimulation() is used.
Let's say I have 3 pairs of pickup and delivery(6 nodes), and their own time windows.
0-Node_start #Index(0)
1-Pickup, 2-Delivery #Index(1,2)
3-Pickup, 4-Delivery #Index(3,4)
5-Pickup, 6-Delivery #Index(5,6)
7-Node_end #Index(7)
How can I force my vehicle to go from node start to index_3, then continue with the rest of the route directly without changing the time window of a node in index_3, or changing the traveling time to 0 from node_0 to node_3? This should be possible regardless of the time taken from index_0 to index_3, as long as time windows allow.
Also, not sure if this is important in this case, but I use FirstSolutionStrategy.GLOBAL_CHEAPEST_ARC
I have found a solution that works for my case, hopeful it will work for others too. I used NextVar
consecutive_locations = [[1,3], [7,9]]
for location_index in consecutive_locations:
routing.solver().Add(routing.NextVar(location_index[0]) == location_index[1])
I used a loop because I have multiple vehicles, each vehicle has a specific starting point, and a location I want it to visit next after starting point.
The solution takes longer though, I think firstSolutionStrategy might be the issue(Not sure)
Using Web Audio API, I'm trying to build an mp3 player with a "Skip ahead 15 seconds" feature.
I'm able to load an mp3 using a source buffer, and can get it to start playing. I want to do something like this, though I know currentTime is not a settable property:
context.currentTime += 15
How do you skip forward n seconds once the song is already playing?
Unfortunately there is no single API call to achieve the desired effect but it's doable. Every AudioBufferSourceNode can only be used once which is why we have to create a new one in order to change something.
Let's imagine we have two variables coming from somewhere called audioContext and audioBuffer. In addition we define two more variables to store the initial startTime and the currently running AudioBufferSourceNode.
let audioBufferSourceNode;
let startTime;
The first time we play the audioBuffer we play it directly from the start. The only special thing here is that we keep a reference to the audioBufferSourceNode and that we remember the startTime.
audioBufferSourceNode = audioContext.createBufferSource();
audioBufferSourceNode.buffer = audioBuffer;
audioBufferSourceNode.connect(audioContext.destination);
startTime = context.currentTime;
audioBufferSourceNode.start(startTime);
If you want to skip ahead some time later the previously started audioBufferSourceNode needs to be stopped first.
const currentTime = context.currentTime;
audioBufferSourceNode.stop(currentTime);
audioBufferSourceNode.disconnect();
In addition a new one needs to be created by reusing the same audioBuffer as before. The only difference here is that we apply an offset to make sure it skips 15 seconds ahead.
audioBufferSourceNode = audioContext.createBufferSource();
audioBufferSourceNode.buffer = audioBuffer;
audioBufferSourceNode.connect(audioContext.destination);
audioBufferSourceNode.start(currentTime, currentTime - startTime + 15);
To be prepared to skip another time it's necessary to update the startTime.
startTime -= 15;
This is of course an oversimplified example. In reality there should be a check to make sure that there is enough audio data left to skip ahead. You could also apply a little fade-in/out when skipping to avoid click sounds. ... This is only meant to illustrate the general idea.
I did some research into this and couldn't really find anything, so if this is a repetitive question I apologize. but anyway I have made a CCB file in CocosBuilder and I would like to start the timeline, for example, at one second instead of playing from the beginning. Is there a way to do this? Thanks for the help guys.
Edit: i would like this to be done in the code.
I am using 2.2.1 Cocos2DX version. I think there is no option to play it from given interval. But you can tweak yourself to get it done. (Not simple one)
You have to go to CCBAnimationManager and there you get "mNodeSequences".
It is dictionary and you get difference properties there like "rotation position etc..."
values there.
Internally AnimationManager reads this value (These values are specified in your CCB)
and puts in runAction queue.
So you have to break it as you want.(Ex. 5 min timeline you have. But you want to start
from 1 min then you have run first 1 min Actions without delay and for remaining you
have properly calculate tween intervals.
It's long procedure and needs calculation. If you don't know any other simpler way try this. If you know pls let us know (Post it).
I am programming a SCORM 2004 product.
I can update the session_time, it works.
I can set the status (passed, failed, etc...)
I also can get the cmi.location time. No problems !
But I don't succeed to get the total time ! (cmi.total_time).
I have tested on 2 LMS :
On Ganesha the API.GetValue('cmi.total_time') is an empty string.
On Moodle the API.GetValue('cmi.total_time') is just a "P".
However i do have the correct logs with correct session times.
Anybody have an idea ?
Thank you !
EDIT.
I also try on cloud.scorm.com and cmi.total_time returns each time PT0H0M0S.
EDIT2. Ooops I deleted Donal's edit.
Based upon the information you've provided, I'm guessing that you're trying to set cmi.session_time and get cmi.total_time in the same learner session, which wouldn't give the response you're expecting.
cmi.total_time contains the total duration of all learner sessions prior to the current one, meaning that it won't contain the value you'd expect it to have until the second learner session.
Once you've set cmi.session_time, close the current learner session by leaving the SCO you're on, and then coming back to it. You should then see that cmi.total_time is now populated with a valid value.
Good Luck!
When you resume the second session and try to retrieve total time, are you able to retrieve the value you stored for cmi.location in the first session? If not, then you are probably not suspending the session. In order for data to be available in the next launch, you need to set cmi.exit to suspend before terminating the first session.
