Middleground Speed

Controls the X and Y speed of the middleground.

Notes

Middleground speed works differently for X and Y:

• X axis: movement is relative to camera movement
• Y axis: position is relative to camera position

As a side-effect, if you change the middleground's Y speed this will also instantly change the middleground's position.

The middleground's movement and position can be calculated using the formulas:
$MGMoveX=CMoveX\cdot (1-SpeedX)$
$MGPosY=CPosY\cdot (1-SpeedY)+OffsetY$

For example, a speed of 1.00 makes the middleground stationary, while a speed of 0.00 matches the camera's movement.

The middleground's default X and Y speed are 0.3 and 0.5 respectively, which makes the middleground move at 70% of the camera's horizontal speed and syncs the middleground's vertical position to 50% of the way between the level's origin and the camera's current position.
