Spells

Spells are very primitive scripts that are defined in the level layout data and can be triggered at runtime based on various triggers. Spells are used to encode the various room-specific gameplay elements that previously were hard-coded into the original game.

Each spell defined has a location in cell space (which may or may not have meaning, depending on the type of spell), as well as a trigger type (which determines what triggers the spell) and a spell type (which determines what the spell does). The various trigger and spell types each have their own parameters which determine their actual behavior.

• A spell may have a prerequisite of having an inventory item of a specific type from a specific room
• A spell may have a prerequisite of a previous spell being invoked (so that several triggers can be required for a specific action)
• When a spell is invoked it is added to Dana's inventory (as an ExecutedSpell) so it can be referenced/checked in the future
• A spell can have one of several triggers and action types:

Triggers

Trigger	Description
Immediate	The spell executes as soon as pre
CastsMagic	The spell executes when Dana casts magic on the spell's location
DanaTouches	The spell executes when Dana touches the spell's location
Potion	The spell executes when Dana ingests a Question Potion
HeadHit	The spell executes when Dana hits his head on the block at the spell's location

Types

Spell Type	Parameters	Behavior	Used in NES Rooms
Change Cell	Position, Cell Type, Modifier, Animate	Changes the layout cell at a specific X/Y to a specific type and modifier. If "Animate" is true, an effect is shown, otherwise the cell is changed without any fanfare. Note that the "FAKECONCRETE" cell type can be used to make a block that Dana can break but still looks gray.	Solomon, Princess, Page of Time, Page of Space
Spawn Object	Spawn ID	Spawns one or more objects from a specific spawn point. You should create a spawn point in Spawns mode that has no timing bits set.	17, 39
Disable Scroll	None	Disable's Dana's scroll / ability to create fireballs	Solomon
Enable Scroll	None	Re-enables Dana's scroll	None
Secret Exit	None	Change the default room exit to the "secret" exit room number	20, 44
Random Cell	Position	Pulls a random item from the room's "random list" and changes the cell at the specified position to a Covered block with that item (and removes the entry from the "random list"). If no more items exist in the random list, a normal tan block is used.	52 (Hidden)
