CLEO Help Cleo Warner

[KennyDixon]

I've been trying to create a script which would make GTA continuously beep if the vehicle's engine is turned off, but unfortunately the crash occurs when i try to turn it on. Where's the problem?

0ABE:  is_car_engine_on 1@

1@ is not a handle to a car, is an empty var.

use

03C0: 1@ = actor $PLAYER_ACTOR car
if 056E:  car 1@ defined
then
    ...
end

 

[KennyDixon]

doesn't "056E:  car 1@ defined" check if there's a vehicle? i need to know if the car's engine is turned off.

If the player is on foot 1@ will be a null pointer, if then you use "0ABE:  is_car_engine_on 1@" you'll crash, so the correct order is get car, check if car exist, check engine status.
