=== Checking variable values ===

* <code>check_variable = { which = <variable> value = <float>/<variable>/<scope.variable>/trigger:<trigger>/modifier:<modifier> }</code>
This checks a variable for the chosen scope – accepts <code>=</code>, <code>>=</code>, <code>></code>, <code><=</code>, and <code><</code> as operators.
: When you are using the value of a variable, you can now (''with 3.1'') use dot scoping: <code>value = owner.capital_scope.my_var</code>
: You can also directly refer to the value of a trigger: <code>value = trigger:num_pops</code>
: A combination of the two is also possible: <code>value = owner.capital_scope.trigger:num_pops</code>
: You can also (with 3.3) directly refer to the value of a modifier: <code>value = modifier:pop_growth_speed_reduction</code>
: This works almost everywhere where you are using variables. The exception is in the basic variable effects and triggers where you are specifying which variable to check or change.

 check_variable_arithmetic = {
 	which = <variable>
 	add/subtract/multiply/divide/modulo = <float>/<variable>/<scope.variable>/trigger:<trigger> <i class=effect-green># (note: this line can be repeated as many times as desired)</i>
 	value <=> <float>/<variable>/<scope.variable>/trigger:<trigger> <i class=effect-green># (the value to compare against)</i>
 }
This checks a variable for the scope if a certain amount of arithmetic is done to it (Note: the variable's value is not changed by this trigger).<sup>''with 3.0''</sup>
