Simple Counter

Counters can be used in various ways, for example:

• Death counters in video games
• Counting how many times the streamer has yawned
• Keep track of how many times a specific command has been used.

While commands and Twitch Channel Point Rewards offer their own built-in counters, they're not as versatile as the following example which utilizes global variables.

Instructions

1. Creating a new action
   First off, we create a new action and assign the trigger that we want to use for the counter to go up. In this example, we'll create a yawn counter and want it to add +1 to the counter when a !yawn command has been used.

2. Creating the global variable
   Now we create our actual global variable. This is done by the Global (Set) subaction that we can find under Core -> Globals -> Global (Set). We can give it any name we want and choose Increment in the dropdown menu, because we want to add a value. We can now type 1 in here to add 1 to the value each time we trigger the action. If we leave it empty, it will also default to 1.

3. Bring the global variable into the action
   Global variables work a little different than regular variables that we use in our actions, because they don't just disappear into the void once the action has finished. So by default they're not available within the action (even after creating it in that very same action), unless we call them. For that we create a Global (Get) subaction to bring our newly created global variable from above as a regular variable into our action.
   
   Counter Global Get Subaction
   
   So Variable Name is the actual name of our global variable (the name in our Global (Set) subaction). In our case, it's yawnCounter.
   The Destination Variable is its new name that we can use as a variable in our action. It can have a different name like yawnCounterVariable, but for sake of simplicity we can just give it the same name.
   The Default Value assigns a value if the variable doesn't exist at the time we are calling it. But since we created it before with our Global (Set) subaction, this is technically redundant.
4. Using our new variable
   We're pretty much done! Now each time we use our !yawn command, it will increment the yawnCounter global variable by +1 and we can then for instance use that in a Twitch Message subaction:
   Streamer has yawned %yawnCounter% times already 🥱
   
   Counter Message
   
   You can also create a second action and choose Decrement on the Global (Set) subaction instead to lower the counter with each trigger.
5. Done!
