Tube Shape Component
The Tube Shape component creates a transparent, enclosed cylindrical volume that’s fit to a Spline component. The dimensions of the tube can be edited with the Radius and Variable Radius properties, and by editing the Spline component. The Tube Shape component is not a mesh, but rather a helper geometry that can be used to define volumes for shape gradients, audio, vegetation, PhysX, and any application that can utilize the Shape EBus. For more information on using Shape components, see Shape components.
|Visible||Enable to always display the shape in the viewport, even when the entity is not selected. Disable to hide the shape when the entity is not selected.||Boolean|
|Game View||Enable to display the shape while in game mode.||Boolean|
|Filled||Enable to display the shape as filled. Disable to display the shape as a wireframe.||Boolean|
|Shape Color||The color of the shape.||Eight bits per channel color: 0-255|
|Tube Shape - Radius||The uniform radius that defines the Tube Shape’s width.||0.1 to Infinity|
|Tube Shape - Variable Radius||The Variable Radius property contains a list with one item for each point of the spline backbone. The list values are added to the uniform Radius values for the corresponding points on the spline to create a tube with a variable radius at each point.||0.0 to Infinity|
|Edit||Choose the Edit button to enter Edit mode. In Edit mode, you can modify the dimensions of the shape in the viewport using the methods outlined in Edit mode actions below. While in Edit mode, the Edit menu in the menu bar displays available actions and hotkeys. To exit Edit mode, choose Done in the component interface.|
- Left-click and drag the black handles at each spline point in the viewport to modify the Variable Radius for each section of the Tube Shape.
Use the following request functions with the
TubeShapeComponentRequestsBus EBus interface to communicate with Tube Shape components in your game.
|Returns the Radius of the tube.||None||Radius: Float||Yes|
|Returns the total interpolated radius of the tube. This is the sum of the radius and the variable radius.||Index: Integer||Total Radius: Float||Yes|
|Returns the Variable Radius along the spline.||Index: Integer||Variable Radius: Float||Yes|
|Sets the Radius of the tube.||Radius: Float||None||Yes|
|Sets the Variable Radius of the tube at a spline point.||Index: Integer, Radius: Float||None||Yes|
Refer to Shape component Ebus interface for a description of functions that are available to all Shape components.
