Conditions
If A - Then B - Else C
Conditions were named as Events before they were renamed on version 0.7.1.
Conditions components a little bit more complex than Actions; they allow to check for conditions and branch from execution threads.
Even if the concept seems complicated, it's actually fairly simple: Imagine you have a Chest that the player can loot. This Chest should only be looted once.
Upon clicking it, if it's the first time, the player gets some items. Otherwise a message can be prompted stating that the chest has already been looted.
Anatomy of a Condition
Conditions work much like Actions, but instead of immediately being executed when called, they perform a set of checks before deciding which action to call (if any at all).
A Conditions object follows the following process:
Check the first Clause
If all Conditions are true
Then executes its Actions
If not all Conditions where true, jump to the second Clause
If all Conditions are true
Then executes its Actions
...
If none of the Clause Conditions is true, then execute a special Actions
Only one set of Actions will be called in a Conditions. If the first Clause of the Conditions are all true, only its Actions will be executed and the rest of the Clause won't even be checked.
Conditions are hard to get at the beginning. For a more comprehensive explanation, watch the following tutorial.
