GTA III Vice City San Andreas MARK_CAR_AS_NO_LONGER_NEEDED


Description
Marks the vehicle as no longer needed
Syntax
01C3: mark_car_as_no_longer_needed [car handle]
Car.RemoveReferences( [car handle] )
Parameter

Native analog
MARK_CAR_AS_NO_LONGER_NEEDED

This opcode marks the vehicle as no longer needed by the script and turns it into a traffic vehicle. When a vehicle is spawned (00A5, etc.) or grabbed from the world (0327, etc.), the vehicle will remain in the game without despawning until this opcode is called. If spawned during a mission, calling the mission cleanup routine automatically marks any vehicles spawned during the mission as no longer needed. When the vehicle is marked no longer needed, it will be treated like a traffic vehicle and will disappear off-screen. However, as long as the vehicle remains on-screen, the script can continue to recognize the vehicle until it disappears. Opcodes that grabs the handle of the vehicle (03C0, etc.) do not treat vehicles as mission vehicles, so using this opcode with disregard will cause problems with other scripts (like during missions) trying to look for the vehicle. Alternative documentation names this opcode as "remove references to car".

Example

The following example, using Sanny Builder, will spawn a Pony close to the player character. A number is displayed on the screen to show the existence of the Pony; 0 means it does not exist and 1 means it does. If the Pony is left alone, it will not disappear. Pressing button 13 (CAMERA key) will mark the Pony as no longer needed. After that, if left alone, the Pony will disappear like normal traffic vehicles.
