Projectile (modding)

Projectiles are separate from parts in the code as well. They have their own components and possible behaviors. Part components won't work on them.

They are all referred to as "bullet" in the source code.

In fact they are defined by the Bullet class :

Encapsulates a single bullet in the scene and all the components contained therein.

Below are the fields for their .rules files. E.g. ion_beam.rules or pd_shot.rules .

List of Data Fields

Complete list

Name	Type	Required	Buffable?	Description
ID	Cosmoteer.Data.ID<BulletRules> meaning : string	Yes	No	Identifier that must be unique across the game.
OtherIDs	Cosmoteer.Data.ID<BulletRules>[]? meaning : array of strings	No	No	Legacy identifiers. You shouldn't need or use this.
Range	float	Yes	Yes	How far the target can be when the projectile is shot at it.
IdealRange	float Or : [float, float]	No	Yes	The game's AI will try to use that weapon from that range. Usually shorter than Range, to prevent the weapon from becoming out of range if the target moves backwards even a little. This can be a range of values (see Type column), not sure why. Used by Ions.
IdealRadius	float Or : [float, float]	No	Yes	??
Speed	float	Yes	Yes	How fast the projectile moves forward when spawned. Acceleration components can completely alter the trajectory.
ReceivableBuffIDs alias ReceivableBuffs	HashSet<string>? meaning : array of strings	No	-	List of buffs this projectile can receive.
ForgetTarget	bool	No	No	??
RandomRotation	bool	No	No	Presumably whether or not the projectile is spawned looking in a random direction.
