Getting Started
Installing and importing
obs-powershell is available on the PowerShell gallery, so you can use these two simple lines to install / import
PowerShellInstall-Module obs-powershell -Scope CurrentUser -Force Import-Module obs-powershell -PassThru -Force
Getting Connected
Before you can use obs-powershell, you'll need to Connect-OBS.
You should only need to do this once: obs-powershell will cache this information.
You can find your WebSocketToken in obs studio in Tools -> WebSocket Server Settings -> Show Connect Info.
Copy the Server Password and set it into a variable, $myToken
PowerShellConnect-OBS -WebSocketToken $myToken
After you've done this once, obs-powershell will attempt to connect every time the module is loaded.
A Quick Example
Once you're connected, check out this nifty short sample of what you can do:
PowerShell# Show-OBS lets you show all sorts of things. # It will return a scene item. $Stars = Show-OBS -Uri "https://pssvg.start-automating.com/Examples/Stars.svg" Start-Sleep -Milliseconds 50 # We can .Hide/.Disable scene items $Stars.Hide() Start-Sleep -Milliseconds 50 # We can .Show/.Enable scene items $Stars.Show() Start-Sleep -Milliseconds 50 # We can make an item small $Stars.Scale(0.1) Start-Sleep -Milliseconds 50 # We can fit it to the screen $stars.FitToScreen() Start-Sleep -Milliseconds 50 # and we can make it big again, with an animation $Stars.Scale("1%","100%","00:00:01") Start-Sleep -Seconds 1 # We can do even more broad animations, like moving things across the screen. $Stars.Animate(@{ X = "-25%" Y = "50%" Scale = "20%" }, @{ X = "125%" Y = "50%" Scale = "50%" Rotation = 180 }, "00:00:05") Start-Sleep -Seconds 1 # To see what any object can do in obs-powershell, run Get-Member. $stars | Get-Member
OBS-PowerShell Effects
obs-powershell gives you the ability to store and create effects that run over time.
For instance, we can FadeIn our stars
PowerShell# Start the FadeIn effect on 'Stars.svg' $Stars | Start-OBSEffect -EffectName "FadeIn" Start-sleep -seconds 1 # Start the FadeOut effect on 'Stars.svg' $Stars | Start-OBSEffect -EffectName "FadeOut" Start-sleep -seconds 1 # Start the Colorloop effect on 'Stars.svg' $Stars | Start-OBSEffect -EffectName "ColorLoop" Start-sleep -seconds 1 # You can get all loaded effects with Get-OBSEffect Get-OBSEffect

How it Works
obs-powershell communicates with OBS with the obs websocket.
obs-powershell has a command for every websocket request.
Because the obs-websocket cleanly documents it's protocol, most commands in obs-powershell are automatically generated with PipeScript.
Depdendencies
To use obs-powershell, you'll need OBS and PowerShell Core. You can run both of these on any operating system.
