A to Z Scripting

Primary contributor - Dragofer

This is an all-in-one resource for scripting as a mapper in TDM. It assumes no prior knowledge of scripting and is aimed in particular at those (like myself) who prefer to learn by looking at existing examples.

The first sections up to "Practical exercise: subtly teleporting the player" are written more in the style of a beginner's guide, while later sections aim to collect everything related to scripting in one place. So the recommended usage of this resource for a beginner would be to use the initial sections to learn the basics, then gradually acquire the remaining techniques & principles whenever you need something new for what you're trying to do.

Why script?

Mappers in TDM are fortunate to have a large selection of entities and systems, such as the objective and stim/response systems, that allow them to use scripted effects without ever writing a line. Those systems are already quite powerful, allowing for relatively complex setups.

Knowing your way around scripts, however, adds a whole new level of control. While a teleportation entity can only teleport something to a predetermined position, a script can automatically calculate the destination, what to teleport and whether to teleport.

A lot can be said about scripting, as this series shows, but as Kingsal once said, even "a little scripting goes a long way". Already the basics give you access to all kinds of new scripted effects and synergise with other systems.
