Speed limit

[isa_Khamdan]

Hello ,

How can I set Speed limit for vehicles inside a colcircle?

[Imposter]

You could change their maxvelocity properties in handling when they hit the colsphere and restore it using elementdata.

[bandi94]

before = getVehicleHandling ( theVehicle, "maxVelocity" ) 
setVehicleHandling ( theVehicle, "maxVelocity",  value ) 
  
  
 -- setting it back  
  
setVehicleHandling ( theVehicle, "maxVelocity",  before ) 

[Imposter]

you can use

  
-- to store 
setElementData(theVehicle, "maxVelocity", theValue); 
-- to obtain 
getElementData(theVehicle, "maxVelocity"); 
  

[50p]

you can use

  
-- to store 
setElementData(theVehicle, "maxVelocity", theValue); 
-- to obtain 
getElementData(theVehicle, "maxVelocity"); 
  

This will not affect the vehicle itself. You still need to use setVehicleHandling, since there is getVehicleHandling there is no need to store element data.

They will still be able to change the speed because I have in-game handling editor so is there another way to add limit for max speed?

like if get element speed ( Vehcile < 75 ) then set element speed to 75?

exmple:

local x,y,z = 0, 0, 0 
local colcircler = createColCircle ( x,y,z,50 ) 
local before 
  
function hit(hitElement, matchingDimension) 
    if (getElementType ( hitElement ) == "vehicle") then 
        local oldmaxVelocity = getVehicleHandlingProperty ( hitElement,  "maxVelocity" ) 
        setElementData(theVehicle, "maxVelocity", oldmaxVelocity) 
        setVehicleHandling ( hitElement, "maxVelocity",  value ) 
    end 
end 
addEventHandler("onColShapeHit", colcircler, hit) 
  
function leave(leaveElement, matchingDimension) 
    if (getElementType ( leaveElement ) == "vehicle") then 
        local oldmaxVelocity = getElementData(theVehicle, "maxVelocity"); 
        if (oldmaxVelocity) then 
            setVehicleHandling ( leaveElement, "maxVelocity",  oldmaxVelocity ) 
        end 
    end 
end 
addEventHandler("onColShapeLeave", colcircler, leave) 
  
function getVehicleHandlingProperty ( element, property ) 
    if isElement ( element ) and getElementType ( element ) == "vehicle" and type ( property ) == "string" then -- Make sure there's a valid vehicle and a property string 
        local handlingTable = getVehicleHandling ( element ) -- Get the handling as table and save as handlingTable 
        local value = handlingTable[property] -- Get the value from the table 
        if value then -- If there's a value (valid property) 
            return value -- Return it 
        end 
    end 
    return false -- Not an element, not a vehicle or no valid property string. Return failure 
end

local x,y,z = 0, 0, 0 
local colcircler = createColCircle ( x,y,z,50 ) 
local before 
  
function hit(hitElement, matchingDimension)

        setElementData(theVehicle, "maxVelocity", oldmaxVelocity) 
        setVehicleHandling ( hitElement, "maxVelocity",  value )

        local handlingTable = getVehicleHandling ( element ) -- Get the handling as table and save as handlingTable 
        local value = handlingTable[property] -- Get the value from the table 
        if value then -- If there's a value (valid property) 
            return value -- Return it 
        end 
    end 
    return false -- Not an element, not a vehicle or no valid property string. Return failure 
end 

People still can change the max speed from the in game handling editor

I want to force the element to slow when the speed get more than 75

[isa_Khamdan]

exmple:

local x,y,z = 0, 0, 0 
local colcircler = createColCircle ( x,y,z,50 ) 
local before 
  
function hit(hitElement, matchingDimension) 
    if (getElementType ( hitElement ) == "vehicle") then 
        local oldmaxVelocity = getVehicleHandlingProperty ( hitElement,  "maxVelocity" ) 
        setElementData(theVehicle, "maxVelocity", oldmaxVelocity) 
        setVehicleHandling ( hitElement, "maxVelocity",  value ) 
    end 
end 
addEventHandler("onColShapeHit", colcircler, hit) 
  
function leave(leaveElement, matchingDimension) 
    if (getElementType ( leaveElement ) == "vehicle") then 
        local oldmaxVelocity = getElementData(theVehicle, "maxVelocity"); 
        if (oldmaxVelocity) then 
            setVehicleHandling ( leaveElement, "maxVelocity",  oldmaxVelocity ) 
        end 
    end 
end 
addEventHandler("onColShapeLeave", colcircler, leave) 
  
function getVehicleHandlingProperty ( element, property ) 
    if isElement ( element ) and getElementType ( element ) == "vehicle" and type ( property ) == "string" then -- Make sure there's a valid vehicle and a property string 
        local handlingTable = getVehicleHandling ( element ) -- Get the handling as table and save as handlingTable 
        local value = handlingTable[property] -- Get the value from the table 
        if value then -- If there's a value (valid property) 
            return value -- Return it 
        end 
    end 
    return false -- Not an element, not a vehicle or no valid property string. Return failure 
end 

Where can I set the max speed in your code?

[Castillo]

Here:

setVehicleHandling ( hitElement, "maxVelocity",  value ) 

[isa_Khamdan]

Here:

setVehicleHandling ( hitElement, "maxVelocity",  value ) 

is there another way to force the car to slow down while it's inside the area without changing the handling?

[Castillo]

What's wrong with changing the handling?

[isa_Khamdan]

What's wrong with changing the handling?

It didn't save the old speed and set it again when you leave

[Castillo]

That's because WASSim made a mistake.

        setVehicleHandling ( hitElement, "maxVelocity",  value ) 
    end 
end

Thanks a lot Castillo , Can you please view my other theard " Little help needed " ?

You're welcome.
