Usage and Notes

Used by the viewer to request region map data. The simulator responds with MapBlockReply.

For simple requests, Flags, EstateID, and Godlike can be set to 0.

MinX, MaxX, MinY, MaxY are grid coordinate ranges. If you wanted to request a block of 4 regions near Da Boom, you might use:

MinX = 1000
MaxX = 1001
MinY = 1000
MaxY = 1001

The resulting regions would be Da Boom, Freelon, Ritch, Minna.

Requests are limited to a maximum of 300 grid positions and it is recommended to limit to 64 or fewer. Exceeding the maximum or supplying otherwise-invalid arguments results in the request being dropped.
