Size

The size of the packet is always 16 bytes.

Type

The packet type from the ISP_ enumeration, always ISP_JRR.

ReqI

ReqI is always equal to zero.

PLID

Zero when this is a reply to a join request, or a real PLID to move an existing car.

UCID

Set when this is a reply to a join request, ignored when moving an existing car.

JRRAction

The action to perform, from the JRR_ enumeration.

Valid values for replies to join requests:

• JRR_REJECT: Reject the join request
• JRR_SPAWN: Accept the join request

Valid values for moving existing cars:

• JRR_RESET: Resets the cars (including repairs)
• JRR_RESET_NO_REPAIR: Resets the car without repairing it

StartPos

An ObjectInfo used to define the spawn/reset point. If it is filled with zeros, the default start point is used. Otherwise, it should have 0x80 for Flags, a 0 Index, and a position/heading to spawn the car.

Notes

You do not need to set ISF_JRR to teleport cars.

When ISF_JRR is set, you need to reply to join requests, which appear as IS_NPL packets with a NumP of zero. If you do not reply with an IS_JRR packet, the player will be able to join after a short delay. In this situation, only one player can join in the response delay, so crowded servers with frequent joins will have to queue.
