ProjArgs

Here are the projectile args, in order:

idx	arg name	type	notes
[0]	_ProjID	Number	Internal, set this to null!
[1]	ProjFX	ProjFX	A number 0 through 29 denoting what ProjFX to use. OSTW users should note that the ProjFX case must be uncommented in index.ostw.
[2]	Color	(Color|Team)	The color of effects or strings.
[3]	String	String	What string or TX to use, if ProjFX = ProjfX.String.
[4]	VisualRadius	Number	Wont impact collision. Projectile Effects have their oversize normalized internally. E.g., VisualRadius = 3 will attempt to make a projectile with a radius of 3m regardless of the actual Proj Effect. (roadhog scrap typically scales differently than firestrike, but BMPW fixes that)
[5]	VisibleTo	(Player|Player[])
[6]	FriendlyTo	(Player|Player[])
[7]	StartPosition	Vector
[8]	Direction	Vector
[9]	Speed	Number
[10]	Gravity	Vector	*Must be a vector (not null!), or type errors will break the projectile.
[11]	Targets	Player[]	An array of players to try for collision.
[12]	Radius	Number	Size is universal/normalized, like in VisualRadius.
[13]	Lifetime	Number	In seconds.
[14]	SaveDataTicks	Number	Save this projectiles ProjData for this number of ticks (capped internally at ~600). I.e., ProjState wont transition from ProjState.Inactive -> ProjState.Unsafe for ticks
[15]	_TimeOfCall	Number	Internal, set this to null or exclude this index!
