If you have to use a trigger, that only waits for a variable and then executes something (displaying briefings in MP for example), then make sure the trigger's size is 0x0. The reason is that if you leave it the default 50x50, I think the trigger still has to calculate who is in it's radius, even if it doesn't matter. (I'm not 100% sure about that one)
Toadlife, i can also only do a speculation on this, but i think
it depends on the condition, wether the trigger is checking
an area or not.
e.g: If you create a trigger with size: 50/50, activated by
west/present
condition: this
or condition: this AND (anything else)
You can always access the trigger's list by using the option:
list triggername
If you use exactly the same trigger without a "this" in the
condition field, you can't access the trigger's list anymore.
I've been working with such triggers lately, so i can ensure
this result for sure.
This result makes me think, that the trigger area will not be
checked, if the condition is not requiring to check it (true,
anything (not alive), "_x blabla" count (units groupx), etc.).
Hope this makes sense to someone else too
