-The StaticEntity defines the model's place and orientation (and some other values). The Model (a cube) is attached to the StaticEntity. With the proper sized collisionshape attached to the StaticEntity you have a "solid" cube. Without a collisionshape, the cube wouldn't be solid and your spaceship could just fly through it. This exampe is quite useful, since you usually can't see a collisionshape's size. If you combine an invisible collisionshape with a fitting model you can see where a collisionshape is for testing purposes. In this special case both the '''scale3D''' and the '''halfExtents''' parameters are identical.

+Backlights are a simple light source in a level. You can specify the colour and size of the light. The Backlight is only a Billboard. This means that it will not cause an illuminated mesh to become brighter. A Backlight is only faked light that may be used for example for blinking light at the wings of a spaceship.

+== ParticleSpawner ==
+
+A ParticleEmitter runs the defined effect forever. If you want to show the effect only once use the more advanced ParticleSpawner class. Search for the XMLPort function in the ParticleSpawner class to see what parameters you can define.
