When you have your entity all set up with bodies, joints and such, it is time to test how it would look in the game. That's what the Entity Preview window is for. In this window you will be able to see how the entity would look ingame, meaning it will be physically simulated. In it you will also get to edit the entity's animations, if any. To start the preview, just press the “Toggle preview” button (the one with cogwheels) in lower toolbar.
The window behaves just like a regular viewport. You can move and orbit the camera around the model the same way. Added to this, you can use the mouse pointer to actually “pick” and drag physical objects in the scene.
Animation controls
Animation: With this control you can select the animation to play, if there is any available. When selected, it will be looped on and on.
Autoplay: when this is checked, pressing the play button will not be needed when selecting an animation on the Animation selector.
