# TrailRenderer Trail renderer
The trail renderer component will render a trail as the position of the moving Entity, which can be used to give a sense of emphasis to the movement of the moving object, or to highlight the path or the position of the moving object.
# In the IDE
To create in the IDE, you only need to select a node in the scene or Prefab and add it in the Inspector:
# Create with code
TrailRenderer is a rendering component, so it needs to be mounted on a non-rendering node.
entity.addComponent(engine.TrailRenderer);
