- Description
- Checks if the player is in a taxi
- Syntax
- 02DE: player [player handle] in_taxi
- Parameter
- [player handle]
- The handle of the player
This conditional opcode returns true if the player is in a taxi. It recognizes the following as taxis:
Id | Name | Id | Name | Id | Name |
---|---|---|---|---|---|
110 | Taxi | 150 | Taxi | 151 | Taxi |
128 | Cabbie | 168 | Cabbie | 166 | Cabbie |
148 | Borgnine | 188 | Zebra Cab | 181 | Bickle'76 |
216 | Kaufman Cab |
