Spellscript blocks are essentially command blocks that can run Spellscript scripts. They may be placed from the Creative inventory and edited by Ops via right-clicking, which will display the Spellscript IDE.
Spellscript blocks may be activated (i.e., have their scripts executed) in several ways, as listed in the table below. The method by which the block is activated is passed to the script as int eventType.
