This is a simple and realitvly foolproof way of testing screen resolution using triggers. It's not commented, and I apologize for my laziness, but the triggers are named so it is easy enough to understand what they are for. If no one gets this, then I will gladly add comments and submit an update.
This little smidgen, a great idea I must say, tells a user how to test screen resolution for his or her campaign. This revised system will use object visible/not visible triggers to detect the presence of units in a certain range, so that the user does not see certain things he or she is not supposed to, like the hidden allied transport or a secret unit. Useful to get the little details right in any campaign.
