How does the SetObjectiveProgress function work?

When you create a quest in the map properties tree, you can define stages. Right-click on a certain item (I don't remember the exact name), press "add," and for each stage, specify the path to the description text. In the quest log, the main description will be displayed first, followed by the additional description corresponding to the current stage.
So, if a quest has these stages, it will start at stage zero, and you can use the function to advance it further, for example, to move to stage 1:

SetObjectiveProgress('quest_name', 1);
