Usage and Notes

RegionData

RegionHandle is the global coordinates of the simulator compressed and encoded into a single U64, with each coordinate taking up 32 bits. It can be visualized as XXXX|YYYY where each character is 8bits.

TimeDilation is used to update the regions time dilation. It is cast to a F32 and then divided by 65535. for actual value.

ObjectData

• FullID is the uuid of the task.
• ID is the region local id of the task, these are used for most operations in place of the tasks uuid.
• State is a legacy field, unused in everything but grass. With grass it is used to determine species of grass.
• Flags used to store flags related to attached sounds.
• PCode is the type of object represented by this task. Possibles include avatars, grass, trees, volumes.
• Material represents the physical material that makes up the task. Possibles include wood, glass, flesh, rubber.
• ClickAction is the default action to take when the task is clicked on in the viewer. Possibles include pay, sit, touch, open.
• ObjectData contains a variable precision set of values for the object. They can include position, velocity, rotation.
• Scale contains the LLVector3 size of the object or task. Is ignored for a few PCodes.
• ParentID contains localid of any task that this task is a child of, used for the creation of object or attachments. Should be 0 if not present.
• UpdateFlags is used to give various pieces of information about the object to the viewer. Stores things like empty inventory, scripted.
