Vector Math

Type: Data
Category: MATH

Performs a mathematical operation between two 3D vectors and returns one component of the result or a scalar.

Properties

Property	Type	Default	Description
Operation	Enum	ADD	See operation table
A	Vector	[0,0,0]	First vector
B	Vector	[0,0,0]	Second vector (ignored for LEN and NORM)
Component	Enum	X	Component to return: X, Y, Z, or W for scalars (DOT, LEN)

Available operations

Operation	Result
ADD	A + B
SUB	A - B
MUL	Component-wise multiplication
SCALE	A * B[0] (scale by first element of B)
DOT	Dot product (scalar)
CROSS	Cross product
LEN	Length of A (scalar)
NORM	Normalized A
LERP	Linear interpolation between A and B with factor B[3]
REFLECT	Reflection of A over normal B

Sockets

Socket	Direction	Type
A	Input	Data (Vector)
B	Input	Data (Vector)
Result	Output	Data (Float)

Typical usage

Calculate velocity length

[On Update] → [BT Condition: {Vector Math: A={linearVelocity}, Op=LEN} > 5.0]
                  └── True ──► [...]  # object moving fast

Dot product for attack angle check

[On Update] → [BTCustomTask:
                   dot = {Vector Math: A={my_forward}, B={to_player_dir}, Op=DOT}
                   # dot > 0.7 ≈ facing me (≈ 45°)]

Notes

• To access the DOT or LEN scalar result, use Component=W (the node's convention for a scalar result).
• Input vectors can come from BGE properties, worldPosition, linearVelocity, etc.
