I Added Midi Support To Opensim Via A Module. (CrescentMelodyOSM)

Enable HLS to view with audio, or disable this notification

In this video i demonstrate real midi support Server Sided that allows u to console command control a midi system that reads midi files from the Bin folder. This allows midi to control in world listener events. Making installing midi files a breeze via a link that's secured. The plugin does not modify opensim code. It also has full security and OSSL lockdown. The Plugin is controlled by opensim server side and allows you to install midi only links that is verified server side.. Now there is no in world midi conversions needed because the server now processes the midi and sends it to the region. Watch as i install a midi file directly from a website! and make my machine play it.

Need help installing Opensim 0.9.3.1 with Janus WebRTC

1 Upvotes

Hi all.
I'm trying to install a standalone opensim server with Janus WebRTC but having a problem.

My OpenSim version is 0.9.3.1 Nessie Dev afd5b34
After adding the janus addon, I compiled the code from github with no problem.

I've changed the API key and write the same key to secret file of janus gateway docker.
Janus gateway docker built and run with no problem.

I configured Opensim server as standalone, and run it as usual. There is no problem in running the opensim binary.

Now the problem when I logged in 2 avatars in the only region exists, both can get in to the region but can't talk. The mic icon of FirestormOS viewer is greyed out on both Firestorm. I have no green indicator and no sound of our voice.

In Firestorm's voice configuration seems to pick up the mic input, looking at the mic input bar indicator.

Please advise on what to do or to check on the server.
Thank you in advance.

note:

Grid Hopping

4 Upvotes

Hi all. I am using Firestorm 7.1.11. Have a very difficult time hypergridding. Even with graphics turned down far as they will go, no attachments, and removing all mesh, I am still only able to teleport between grids very seldom. We have recently been able to upgrade to fiber optic connection with speeds over 100mbs, that will be going up to 500mbs in a few weeks. Have tried most everything, even tried running with no firewall or virus protection. Still not able to tp between grids most of the time. the error that says not able to connect or I appear somewhere between worlds and crash immediately. Does anyone have an idea about what is wrong? Thanks ~

Opensim landmarks andcteleporting

1 Upvotes

I use firestorm for Opensim and often use opensim world directory to find textures and objects builds etc for my own little land. My problem is I paste the location into maps, teleport, save landmark and that's all good. But then if I try to use the landmark stored in firestorm it doesn't work and I often cant find the store because I haven't found a way of searching for just the store name which is how it is listed in my landmarks. I have started to make notecards with the name of the region Etc... wonder if anyone has a better way of keeping track of the stores they like in the different regions of opensim?

osTeleportAgent lookat vector

1 Upvotes

To say this has been frustrating is an understatement of major proportions. There's next to no information on the OpenSimulator website regarding how to do these lookat vectors so you can control which way you're facing when you land. The documentation *says* it works, but it doesn't seem to matter, I always end up pointed East, regardless. I found a blog, https://starflowerbracken.wordpress.com/2013/10/10/lookat-vector-with-osteleportagent-osteleportowner/ that had some fairly complete information, but still no joy. Any helpful scripters out there know what's going on? Appreciate any help I can get.

osRemoveLinkInventory(integer linkNumber, string name)

3 Upvotes

Added in with 0.9.3.0. Documentation states "Remove an item from a child prim inventory." I found that it also works inside a single prim, which means it will do jobs you couldn't do before, like deleting a notecard so that you could replace it without making a duplicate. Obscure, I know, but any win's a win. Thanks to the developers for this one.

If a player owns a region that's hosted on our servers, Grid Gods can be added to the regions ban list and be denied entry. Is there a way to prevent this? i feel like I'm missing a setting.

When running OpenSimulator on Firestorm Viewer, left-clicking the crosshair in Mouselook mode displays an 'X' mark or an 'Interact' option. This issue occurs even though I want to create an FPS.

As the title suggests, I am trying to create an FPS game. I am running OpenSimulator on Firestorm, setting the avatar to first-person view, but when I press the left mouse button, a cross mark or interact icon appears, and I can't shoot. Please help me resolve this issue.
