## ActivateFCurve

### Description

Activates or deactivates an entire curve or just a region of the curve.
ActivateFCurve is the command equivalent of the same functionality available in the DopeSheet. It should be used when trying to emulate the DopeSheet behavior.

### Scripting Syntax

    ActivateFCurve( [InputObjs], Activate, [StartFrame], [EndFrame], [Type] );

### Parameters

Parameter | Type | Description
--- | --- | ---
InputObjs | String | List of animatable parameters (for example "cone*/kine.local.pos"). This parameter uses the Type parameter to interpret which parameters to use in this way: - If Type == siInputParameters then InputObjs is used exactly as input (either from the specified list or the animatable parameters on the selected objects). - If Type == siAnimatedParameters then InputObjs is expected to be a list of objects on which each animatable parameter will be affected. - If Type == siAllAnimatedParameters then the value of InputObjs is ignored and instead the command uses all animated parameters on all objects in the entire scene. Default Value: If no value is specified for this parameter, the Object List will use the selected objects or parameters respecting the scope indicated by the Type argument.
Activate | Boolean | Activate or Deactivate the entire curve or the input range.
Possible Values: | Description:
0 | False
1 | True
StartFrame | Double | Start frame of the region of the fcurve(s) you want to operate. Leave both Start and End blank for entire curve. Value range -Inf, +Inf
EndFrame | Double | End frame of the region of the fcurve(s) you want to operate. Leave both Start and End blank for entire curve. Value range -Inf, +Inf
Type | siParameterScope | Parameter scope of the operation Default Value: siInputParameters
