Does anyone know how to make a onebang object from scratch?

Basically I need a gate or spigot that can be triggered to only output one thing and then shut itself.

I can manage to get one to "work" sending the bang to a spigot and routing the spigot's output to turn off its control inlet, but not surprisingly I get stack overflow errors in the Pd window. I'm happy that it "works," but I'm worried about the errors.

Any help would be much appreciated!
Thanks!

this seemed to be what you are asking for

bang or message or whatever
|
spigot ------<
| |
| |
bang------toggle

when something goes through the spigot, the bang gets hit and switches the toggle. If the toggle is [x] then it goes to zero, [ ], closing the spigot. You would need to reset the toggle to [x] for the next message you want to push though.

This can of course be modified with a [select] if a specific message needs to close the spigot.

Totally. It works. I must have some other funky logic happening in the patch that is creating the loop. Thanks!

so, I didn't know that onebang was a Max object. Was messing around in PD to make the example from the last post into an abstraction and found that there is a onebang object in the cyclone lib.

running Pd version 0.39.3-extended on XP

Attached the abstraction renamed oneMessage.pd since you can't send floats etc through onebang
