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.
