SetModelHandling: Difference between revisions

Revision as of 10:40, 17 October 2011

This function is used to change the handling data of all vehicles of a specified model.

Syntax

bool setVehicleHandling ( int modelId, string property, var value )

Required Arguments

modelId: The vehicle model you wish to set the handling of.
property: The property you wish to set the handling of the vehicle to.
value: The value of the models's handling property you wish to set, or nil if you want to reset the handling property to its default value.

Returns

Returns true if the handling was set successfully, false otherwise.

Handling Properties

See below a list of valid properties and their required values:

maxVelocity	Float	0.1	200000.0
engineAcceleration	Float	0.0	100000.0
engineInertia	Float	-1000.0	1000.0	Inertia of 0 can cause a LSOD. (Unable to divide by zero)
driveType	String	N/A	N/A	Use 'rwd', 'fwd' or 'awd'.
engineType	String	N/A	N/A	Use 'petrol', 'diesel' or 'electric'.
brakeDeceleration	Float	0.1	100000.0
brakeBias	Float	0.0	1.0
ABS	Boolean	true	false	Has no effect.
steeringLock	Float	0.0	360.0
suspensionForceLevel	Float	0.0	100.0
suspensionDamping	Float	0.0	100.0
suspensionHighSpeedDamping	Float	0.0	600.0
suspensionUpperLimit	Float	-50.0	50.0	Can't be equal to suspensionLowerLimit.
suspensionLowerLimit	Float	-50.0	50.0	Can't be equal to suspensionUpperLimit.
suspensionFrontRearBias	Float	0.0	1.0	Hardcoded maximum is 3.0, but values above 1.0 have no effect.
suspensionAntiDiveMultiplier	Float	0.0	30.0
seatOffsetDistance	Float	-20.0	20.0
collisionDamageMultiplier	Float	0.0	10.0
monetary	Integer	0	230195200	Get works, set is disabled.
modelFlags	Hexadecimal/Decimal	N/A	N/A	Property uses a decimal value, generated by a hexadecimal value. Either use 0x12345678 or tonumber ( "0x12345678" ). See projectcerbera for possible values.
handlingFlags	Hexadecimal/Decimal	N/A	N/A	Property uses a decimal value, generated by a hexadecimal value. Either use 0x12345678 or tonumber ( "0x12345678" ). See projectcerbera for possible values.
headLight	String	N/A	N/A	Get works, set is disabled. Available values: 'long', 'small', 'big', 'tall'.
tailLight	String	N/A	N/A	Get works, set is disabled. Available values: 'long', 'small', 'big', 'tall'.
animGroup	Integer	??	??	Get works, set is disabled due to people not knowing this property was vehicle-based and caused crashes.

This function will reset the handling of Bullet vehicles to its default state.

function resetHandling()
	for k,_ in pairs(getModelHandling(541)) do
		setModelHandling(541, k, nil)
	end
end
addEventHandler("onResourceStop", resourceRoot, resetHandling)
