Set the ISF_REQ_JOIN flag in the IS_ISI to receive join requests A join request is seen as an IS_NPL packet with ZERO in the NumP field An immediate response (e.g. within 1 second) is required using an IS_JRR packet
In this case, PLID must be zero and JRRAction must be JRR_REJECT or JRR_SPAWN. If you allow the join and it is successful you will then get a normal IS_NPL with NumP set. You can also specify the start position of the car using the StartPos structure.
IS_JRR can also be used to move an existing car to a different location. In this case, PLID must be set, JRRAction must be JRR_RESET or higher and StartPos must be set.
