Gets the value of the player's velocity. You must specify the component that you want to check, eg. "Pos Y" to check the Y-velocity.

Format: Vel [component]

Arguments:

- [component]: X, Y

Return type: float

Error conditions: none

Details:

For Vel X, a positive value indicates that the player is moving forward. (This behavior is the opposite of HitVel X's behavior.) For Vel Y, a positive value indicates that the player is moving downward.

Example:

`trigger1 = Vel X > 0.5 ; True when the player's X-velocity greater than 0.5.`
