Notes

There aren't any notes for this function.

Examples

Example 1 - JavaScript - Client-Side:

/* example code provided by DrFauli */
addCommandHandler("drivewander", function(cmdName, params) {
	// current vehicle/ped handle
	let thisVeh = null;
	let thisPed = null;
	// check if player is in a car
	if (!localPlayer.vehicle) {
		natives.requestModel(-956048545) // Taxi
		natives.requestModel(8772846); // Taxi Driver
		natives.loadAllObjectsNow();
		// spawn the car
		thisVeh = createVehicle2(-956048545, localPlayer.position, true);
		thisVeh.heading = localPlayer.heading;
		// spawn the driver
		thisPed = natives.createCharInsideCar(thisVeh, 1, 8772846);
		// prevent ped from leaving the car screaming by marking it as mission_char first
		natives.setCharAsMissionChar(thisPed, true);
		natives.setCharStayInCarWhenJacked(thisPed, true);
		// warp player into passenger seat id 0 (next to driver)
		natives.warpCharIntoCarAsPassenger(localPlayer, thisVeh, 0);
	}
	else {
		thisVeh = localPlayer.vehicle;
		thisPed = thisVeh.getOccupant(0);
	}
	// get speed and driveStyle from params
	let splitParams = params.split(" ");
	let driveSpeed = Number(splitParams[0]); // default is 20
	let driveStyle = Number(splitParams[1]);
	// let this car randomly drive around
	// [syntax]: pedHandle, carHandle, driveSpeed, driveStyle
	natives.taskCarDriveWander(thisPed, thisVeh, driveSpeed, driveStyle);
	return true;
});

driving style behavior

	traffic lights	other cars	pedestrians	blinkers	when stuck
0	ignore	drive around	drive around	not used	reverse
1	stop on red	stay behind	stop and honk	used on intersections	wait
2	ignore	drive around	drive around	not used	reverse
3	ignore	ignore	ignore	not used	reverse
4	ignore	stay behind	stop and honk	not used	wait
5	stop on red	drive around	drive around	not used	reverse
6	stop+reversing	drive around	drive around	not used	reverse
7	stop on red	stay behind	stop and honk	used on intersections	wait

notes

driving styles 0 and 2 seem to be identical.
driving styles 1 and 7 seem to be identical.
using values < 0 or > 7 will behave like 3
the AI will slow down for corners and intersections, but won't break for "drive around" obstacles.

There could be small distance and/or speed differences when "drive around" is used.‎
It is also unclear if the AI drivers are able to see objects like light poles or traffic lights while evading.

The vehicle.carWanderRandomly function has the same functionality in the 3D universe games (GTA III, Vice City, and San Andreas). The extra driving parameters for those games can be set with vehicle.setDrivingStyle and vehicle.setCarCruiseSpeed
