| IS_MCI | |
|---|---|
| Car info for multiple cars (more detailed than IS_NLP) | |
| Overview | |
| Size | 4 + NumC * 28 |
| Type | ISP_MCI (38) |
| Usage | info |
| Previous packet IS_NLP |
Next packet IS_MSX |
The Multi Car Info is sent by LFS as a reply to a TINY_MCI request, or at regular intervals if requested in IS_ISI.
Packet details
| Type | Name | Description |
|---|---|---|
| byte | Size | 4 + NumC * 28 |
| byte | Type | ISP_MCI |
| byte | ReqI | 0 unless this is a reply to an TINY_MCI request |
| byte | NumC | number of valid CompCar structs in this packet |
| CompCar | Info[MCI_MAX_CARS] | car info for each player, 1 to MCI_MAX_CARS (NumC) |
Size
The size of the packet varies from 4 to 452 bytes, depending on NumC. The maximum size is governed by MCI_MAX_CARS:
const int MCI_MAX_CARS = 16;
Type
The packet type from the ISP_ enumeration, always ISP_MCI.
ReqI
ReqI is equal to zero, unless the packet is a reply to a TINY_MCI request.
NumC
The number of cars in the packet.
Info
A list of CompCar structs, one for each car.
Notes
Since the maximum number of cars per packet is currently 16, you can receive up to 3 IS_MCI packets for each request or after each interval. If you need to process data for all cars, you should check the CompCar Info flags for CCI_FIRST and CCI_LAST, to make sure you include every car.
