How do you create a descent (Ramp) from an ascent (Raise)?

Take the tool and carefully draw a line from the corner tile downwards.

And how do you display messages when encountering specific armies ("colored" and neutral) and when entering various objects (mines, towns, etc.), and when being in certain locations? And how do you give the character resources, troops, and artifacts with these messages?

Place a trigger on visiting an object and include the function ShowFlyingSign(path to the message, object name, player ID, time);
To handle encounters with monsters, first disable the monster using the function SetObjectEnabled, and then, in the trigger, enable it after displaying the sign and run MakeHeroInteractWithObject(monster name);
Correspondingly, resources, troops, and artifacts are given using the appropriate functions within the trigger.
