# LineRenderer Line renderer
The line segment renderer component requires an array of two or more points in three-dimensional space. You can use the line segment renderer to draw anything, from a simple line segment to a complex spiral.
# 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
LineRenderer is a rendering component, so it needs to be mounted on a non-rendering node.
const line = entity.addComponent(engine.LineRenderer);
