=== Using variables – the wheres ===

We can (now ''with 3.1'') use variables in a lot of different places:
* Any trigger that is comparing a single number, including ones with <code>{ }</code>. E.g. "<code>num_pops > my_var</code>", "<code>intel = { who = from value < trigger:num_pops }"</code>.
* Any effect using a single number, including ones with <code>{ }</code>. E.g. "<code>add_experience = my_var</code>".
* The count parameter of while loops!
* Certain effects let you input variables for various reasons. E.g. <code>multiplier</code> on <code>add_modifier</code> (the modifier's bonuses will be multiplied by the variable), <code>mult</code> on <code>add_resource</code> (multiplies all resources granted by that effect).
* Resource tables and triggered resource tables can take a "<code>multiplier = <variable></code>", the variable must be in the planet scope  and may not be dot scoped:
<pre>	resources = {
		category = planet_buildings
		cost = {
			trigger = { <triggers> }
			minerals = 100
			multiplier = my_var/trigger:num_pops
		}
	}</pre>
* [[MTTH]]/AI Chance modifiers:
<pre>	ai_chance = {
		factor = 1
		modifier = {
			add/factor = my_var/trigger:num_pops
			is_variable_set = my_var
		}
	}</pre>
* Ordered script lists: scope to the country with the highest (or 3rd highest, or lowest) value for a variable or trigger.
* In [[Localisation modding|locs]]: if you refer to <code>[This.my_var]</code>, it will print the value of the variable, so long as the variable is set.
