SURFACE_FROM_CURVE_OVER_TIME

This element can be used to create custom surfaces based on the variations of an existing curve: the surface represents the evolution of the curve over time.

Attributes brief detailed show all inherited

	Name	Description	Default
	name	Displayed name of the surface	empty
	comment	Comment about the surface	empty
	duration_ms	Duration for the swept curveThe x coordinate bounds will be [0;duration_ms]	5000
	refresh_time_ms	interval between two sampled valuesYou should increase this value if you are concerned with display performance issues	50
	curve_id	Identifier of the curve sampled over time to create the surfaceMandatory	empty
	paused	parameter sampling pausedUse this parameter to pause the surface (it will stop sampling the curve)	false
Events
	value_changed	the event is triggered anytime the value of the object has changed
Common attributes
	id	Identifier of the elementThe id of an element has to be globally unique. Don't start with a digit for AngelScript compatibility.	empty

Examples

The following example creates a surface sampling the curve every 10 ms for 10 seconds:
