RED Groups

Movers are any object, brush, or combination thereof that are setup to move around the level in-game. Things such as doors, lifts, or a tram would be considered a mover. Movers are created in Group Mode and use a keyframe system to specify how groups should move. Also, a mover can be made up of many objects and/or brushes.

Follow these steps to create a mover group:

1. Create the brushes/objects you wish to turn into a mover.
2. Place them where you want them to start moving from (the initial state). Texture the brushes as needed.
3. Go into Group Mode and select the brushes/objects (even if it's just one brush or object) and create a user group for them.
4. Find the user group you just created and select it.
5. Hit the "Keyframe" button to turn this group into a Moving Group and create the master keyframe for it. The master keyframe shows the starting position for this mover and is shown as a gold key object.
6. After you create a mover you can "animate" it by giving it more keyframes that tell the mover what to do and where to move to.

Keyframes

The editor uses keyframes as the method for animating how movers move. They are a way to tell the game engine where the mover should go and in what order. You also use the keyframes to tell the mover how fast to go to the next keyframe, if the mover should reverse or start the process over when it finishes, and other such information.
