Questions about the Heroes 4 map editor.

What I mean is this: let's say you approach some object, a message appears, and then after a few days, another message is activated – something like that, I tried to explain.

Let's say you want a certain message to appear 5 days after you activate a specific local event. In the local event, you set the variable "A" to the current day. You create a repeating event that will be activated from the first day and then every day, and in it, you have "condition: if-equal-add[variable "A"+5] -- then-show message, etc."
And then the most important thing: you create a calendar event that is activated on the first day and never again, and in it, you assign the largest negative number to the variable "A", just fill in nines in all the fields.
