Function. Outputs a direction vector from one point to another with a specified length.

Mathematically: normalize(To - From) × Length.

Commonly used to calculate initial velocity of particles emitted toward or away from a point.

Properties & inputs:

• From (input | property): The starting point.
• To (input | property): The target point.
• Length (input | property): The length of the resulting direction vector.

Output:

• Direction vector with the specified length.
