v1.0
Modifies a rule in a connection or value mapping template, or in a clip's local value map.
Note that you cannot change the left-hand side (the Items part) of a rule in a clip's value map.
SetMappingRule( MappingTemplate, From, [To], [Index], [Active], [PoseOffset] ); |
Parameter | Type | Description | ||||||||
---|---|---|---|---|---|---|---|---|---|---|
MappingTemplate | String |
Mapping template or a clip value map. The value map of a clip is named " |
||||||||
From | String | The Map From part of a connection mapping rule, the Parameter part of a value mapping rule, or the Item part of a clip value mapping rule. | ||||||||
To | String | The Map To part of a connection mapping rule, the Expression part of a value mapping rule, or the Expr part of a clip value mapping rule. | ||||||||
Index | Integer |
Specifies the rule to modify. Rules are numbered starting at 1, but an index of 0 or 1 refers to the first rule. Default Value: 0 (the first rule) |
||||||||
Active | Integer |
Sets the activeness of the rule. Default Value: -1
|
||||||||
PoseOffset | Integer |
Sets the pose offset activeness for the object. Default Value: -1

' This example illustrates several mapping template commands. ' It creates an Action on a sphere, then uses a value mapping ' template to create an offset effect when this Action is instanced. ' Then it creates a connection mapping template so the sphere ' animation can be applied to a number of different objects (using a ' wildcard to do this). Finally, the second clip (driving the cones) ' is accessed as a value map itself, and clip effects on it are ' created using SetMappingRule.
