The Broken Hourglass: More About Level Paths
6:00 AM | Cord Kruse | Comment on this story

Last week's informational update for Planewalker Games' upcoming RPG, The Broken Hourglass, focused on how the game deals with character classes and level advancement. This week the discussion continues with a peek inside Hourglass' inner workings and a quick tutorial demonstrating how to create a new level path with just a few lines of scripting.

There are a number of engine functions which govern the spending of experience points on character abilities. _attribute_upgrade causes a character to spend XP to purchase points in a valid skill or attribute, while _toggle_trait adds a trait to that character. Supporting functions like _can_toggle_trait (to ensure that there are no unmet prerequisites for the trait) and _attribute_upgrade_cost can help us determine whether the purchases we want to make are possible.

But rather than reinvent the wheel and apply this logic every single time a character levels up, we have a function which performs the skill buying and experience bookkeeping automatically. This makes the creation of a new level path extremely easy by following just a few simple rules.
