Why would you create a new function for each variable?

You only need one function and you simply pass in each variable you want to change.

Let`s say you got var1, var2 and var3 you want to increase by one.

You use the function in the code above and call it for each variable like this:

SetTimerEx("VariableIncrease", 1000, false, "d", var1);
SetTimerEx("VariableIncrease", 1000, false, "d", var2);
SetTimerEx("VariableIncrease", 1000, false, "d", var3);

And all of them will be increased by one after 1k ms.
