    No, I had a custom event which adds a target, then sets the new target index as the 'one to use' variable. It messed up because of the order I called it.

    You use AddSendOscTarget to do that ?

    It returns an index to actually send a message to the new "target".
    You should set a variable with this index and use it in SendOsc function.
    Hardcoding "1" is hardly a good idea...

    I use unreal to prototype gameshow ideas for a TV company. If i'm not there when they're pitching ideas (like yesterday) I have to talk someone through finding ip addresses, editing the python scripts to do this etc. It's a nightmare - Ive also found it's actually a lot more responsive to have the iPad to talk directly to the engine too.

    I had a problem yesterday (my stupid fault) where I was setting a default ip for the OSC target at begin-play in my OSC blueprint, but at the same time another blueprint was reading a database and pulling an IP from that and setting a target IP too. On the machine they were using the OSC blueprint with the default IP lost the race and was set second, if you know what I mean, so they couldn't control the system - it's always a nightmare when i'm not there!

    It is quite overkill to run UE4 to prototype OSC messaging...

    But I do exactly the same: I find it much easier to use than python, Pd, etc.

    It's not every frame. What i've got is like a quiz game. The 'host' has an ipad with all the questions and answers on and triggers the engine to display/reveal answers. On the engine side i'm loading the question data from an SQLite database and sending this data over to the iPad. So when we select a new question the whole ipad interface is altered, as well as the 100 or so text labels, I sometimes have to refresh positions,opacity, and colour of each label - which can be 500 or more OSC tx's at a time. This is why I use a stack.

    I'll add a request to your github page. I imagine you'll have a struct with the address and data in an array which is bundled maybe?

    Thanks so much - it's really helping me develop my game prototypes - before I was using python as an OSC intermediary and sending commands through it over a socket connection.

    Hi !
    Indeed, an "OSC bundle" is a container, that may contains other bundles and messages.
    It is sent in one piece and the order of inner bundles/messages is kept.

    If you really need to update every line every frame (do you ?) I agree it would probably solve your issue.

    It is not (yet) supported by the plugin though, but file an issue on the GitHub (https://github.com/monsieurgustav/UE4-OSC) as a reminder.

    Hi Monsiergustav,

    I've been using the plugin to great effect with touchosc - you probably know it. I'm sending commands out of the engine into my iPad to update text fields - because TouchOSC has only non-wrapping text labels I'm using 4 or 5 labels per block of text - and there are about 25 of these blocks.

    In short I've got a stack on a timer in the engine which I often send 100+ osc commands to. Is there a way to bundle lots of commands into one osc transmission for a more optimised

    A label might be a string sent to /data/label(n)/text 100 times - I have to throttle the osc txrate or I lose data

    Thanks! And great work.

    Dan

    That's great! I'll look forward to fiddling with that soon.

    Great work!

    Hi !
    Sorry for the late answer : at the time it was not possible, but now it is !
    The latest commit add the AddSendOscTarget blueprint function.

    Hi m.gustav.

    Just started using this on a project - it works very well!

    Thanks for your effort kind efforts in the community.

    Is there a way to define the addresses/ports at runtime?

    Dan

    Glad you like it !

    I had a look at your crash log, and they seem unrelated to the OSC plugin.
    If they are actually related, feel free to post an issue on the GitHub !

    Your plugin is just fantastic. It's really nice of you to keep it up to date. Please keep up the good work ;-)

    I tried using it with 4.10.1 and my it would work but really unreliably... meaning sometime it would crash. Sometime not. But as I have a really minimal knowledge of programming I am not sure the problem was your plugin. Actually pretty sure it was not. Here is my post about my crash. I might be helpful...

    https://answers.unrealengine.com/que...101-crash.html

    So for now I got back to 4.7.

    Still thank you so much. Please keep supporting it ;-)

    Did you click "set as default" in the OSC plugin settings ?
    That's a tricky thing: unless you click "set as default", the settings are ignored by the build.

    Also, know that you're (one of) the first person to use the plugin on Android !
    I failed to set-up an Android dev env (maybe because if my out of date device), so I can't really help you on any Android specific problem.
    If you can "remote debug" the OSC plugin (put a breakpoint in the C++ "SendOsc" function) it should be OK.

    I think your issue is that your send address is 127.0.0.1, which mean "myself".
    So the Android is sending to itself, not the PC.

    When a network communication does not work, try to break your problem into many sub problems with tools you know are reliable.
    Example : use TouchOSC on Android to send messages, use an OSC monitor software on Windows to test the receiving part (there might be a firewall, a misconfiguration), etc.
    Thanks! I´m using the TouchOSC on Android and it´s working. Also the OSC monitor works fine. The problem is in the app I´m doing in Android that doesn´t seem to connect with the PC. I changed the IP but it still doesn´t work. I´m thinking that maybe the problem is the Android permits but I´m not sure. Do you have another idea about what else might be messing up with the communication would be of much help Click image for larger version
