AW_HUD_ELEMENT_ID
Type
Integer
Description
Id of a HUD element.
Notes
This attribute must be set to a positive integer (1 or larger). Setting it to 0 and placing a blocking call to aw_hud_create will return RC_TIMEOUT after a delay.
The value of this attribute uniquely defines a HUD element for one particular user. The value is stored by the Activeworlds browser when a new HUD element is created using aw_hud_create. Any subsequent calls to aw_hud_create with AW_HUD_ELEMENT_ID set to the value it was set at creation will cause the new element to replace the old one, rather than create an entirely new element.
When aw_hud_destroy is called, the HUD element with the Id of AW_HUD_ELEMENT_ID will be removed from the 3D viewport.
This Id is used in AW_EVENT_HUD_CLICK to identify which clickable (i.e. AW_HUD_ELEMENT_FLAGS had the flag AW_HUD_ELEMENT_FLAG_CLICKS) HUD element was clicked by a user.
