Hello. How can I change "updateVehiclePhysics" function in FS19? I want switch "axisSideIsAnalog" to "true"
Bilbo Beutlin (BBeutlin) 06.09.2020 23:44
You can change default functions by using 'Utils.prependedFunction()' or 'Utils.appendedFunction()' or 'Utils.overwrittenFunction()' - the syntax is "oldFunction = Utils.*Function(oldFunction, newFunction)".

If using overwrittenFunction() you must be aware that another mod could do the same. So it's better to use prepended|appendedFunction whenever possible, since these are queued.

Thank. I will try

*sigh* What do you expect? Here are no clairvoyants.
We need at least a description which function method you have used and what you have changed vs. original.

If you want to use the 'overwritten' method, test at first with a clone of the original function. Only when everything is running fine make your changes.

If remove "function camBlock:updateVehiclePhysics" and "Drivable.updateVehiclePhysics", then there are no errors
Bilbo Beutlin (BBeutlin) 07.09.2020 21:14
Forget it! Do you really think your poor two lines can replace the original code? It is perhaps suitable for appending/prepending, but not for overwritten function.

What did I say? For overwritten function at first begin with the original function code. If you're unsure change and test it stepwise.
Kirill Teltevskoy (Atrides) 08.09.2020 09:48
I took the original function:

camBlock = {};

function camBlock.prerequisitesPresent(specializations)
return true;
end;

function camBlock.registerEventListeners(vehicleType)
SpecializationUtil.registerEventListener(vehicleType, "onUpdate", camBlock);
end;

function camBlock:onUpdate(dt)
if self.spec_enterable ~= nil then
if self.spec_enterable.isEntered then
if Input.isKeyPressed(Input.KEY_lshift) then
self.spec_enterable.activeCamera.isRotatable = true;
else
self.spec_enterable.activeCamera.isRotatable = false;
end;
end;
end;
end;

function camBlock:updateVehiclePhysics(axisForward, axisForwardIsAnalog, axisSide, axisSideIsAnalog, doHandbrake, dt)
local spec = self.spec_drivable
axisForward = axisForward
axisSide = self:getSteeringDirection() * axisSide
local acceleration = 0
if self:getIsMotorStarted() and self:getMotorStartTime() <= g_currentMission.time then
acceleration = axisForward
if math.abs(acceleration) > 0 then
self:setCruiseControlState(Drivable.CRUISECONTROL_STATE_OFF)
end
if spec.cruiseControl.state ~= Drivable.CRUISECONTROL_STATE_OFF then
acceleration = 1.0
end
end
if not self:getCanMotorRun() then
acceleration = 0
if self:getIsMotorStarted() then
self:stopMotor()
end
end

if self.getIsControlled ~= nil and self:getIsControlled() then
local targetRotatedTime = 0
if self.maxRotTime ~= nil and self.minRotTime ~= nil then
if axisSide < 0 then
-- 0 to maxRotTime
targetRotatedTime = math.min(-self.maxRotTime * axisSide, self.maxRotTime)
else
-- 0 to minRotTime
targetRotatedTime = math.max(self.minRotTime * axisSide, self.minRotTime)
end
end
self.rotatedTime = targetRotatedTime
end
if self.firstTimeRun then
if self.spec_wheels ~= nil then
WheelsUtil.updateWheelsPhysics(self, dt, self.lastSpeedReal*self.movingDirection, acceleration, doHandbrake, g_currentMission.missionInfo.stopAndGoBraking)
end
end
return acceleration
end;
Drivable.updateVehiclePhysics = Utils.overwrittenFunction(Drivable.updateVehiclePhysics, camBlock.updateVehiclePhysics);

Result in the log:

Bilbo Beutlin (BBeutlin) 08.09.2020 18:36
You can read, can't you? I said "at first begin with the original function code".
So start with the UNCHANGED function with the parameters "updateVehiclePhysics(axisForward, axisSide, doHandbrake, dt)"
Though there are additional parameters documented, may have a reason that they are not used in original code.
Kirill Teltevskoy (Atrides) 08.09.2020 20:21
Ok. Now in the log:

The error comes most probably if "acceleration = axisForward" was assigned.
That might be caused by the special handling of the Utils.XFunction().
Try with the parameters "updateVehiclePhysics(superFunc, axisForward, axisSide, doHandbrake, dt)"

You could also try a "dirty hack" (for personal use only, not recommanded for publishing):
Instead the Utils.overwrittenFunction() use
Drivable.updateVehiclePhysics = camBlock.updateVehiclePhysics;
Kirill Teltevskoy (Atrides) 09.09.2020 08:42
Thank. Works with "superFunc". Log clean
Kirill Teltevskoy (Atrides) 09.09.2020 10:20
Can you explain to me how to look for functions? For example, I want to find how to count the movement of the mouse along the X axis. How do I find how to write a function?
Bilbo Beutlin (BBeutlin) 10.09.2020 00:35
For finding certain functions you must be a little creative and a good analyst. Try to imagine in which category the issue is used and search in the LUADOCs in appropriate section.
It can be helpful to DL and install the Giants Remote Debugger. This comes with a zip archive of most used LUA codes and is a good supplement to the LUADOCs here on GDN. Very comfortable if you unpack the zip - this enables extensive search, eg. with Notepad++ "search in files".
Kirill Teltevskoy (Atrides) 10.09.2020 10:02
Thanks
Kirill Teltevskoy (Atrides) 10.09.2020 19:53
I cannot find the amount of movement of the mouse on the X axis. Can you help me? I remember that in previous FS versions it was "InputBinding.mouseMovementX". And in FS19 I can't understand
Bilbo Beutlin (BBeutlin) 11.09.2020 05:06
See above my recommendation: install the Giants Remote Debugger, unpack the "gameSources/Farming_Simulator_19-1.5.1.0.zip" to a separate folder. Here you do with Notepad++ a "search in files" for "mouse". You'll get lots of examples how mouse related values are used in game.
Kirill Teltevskoy (Atrides) 11.09.2020 07:37
I did it all. Found "VehicleCamera: actionEventLookLeftRight". I understand that this is a left-right mouse view of the camera. And "inputValue" is the variable I need. But how do I use it in my script? There is also "self.lastInputValues.leftRight". But I cannot use this either. Error in the log "nill value"
Bilbo Beutlin (BBeutlin) 11.09.2020 11:41
If you look through the LUAs, most time is used something with "mouseEvent(posX, posY, isDown, isUp, button)"

There are also mouse values in the table "g_currentMission.inputManager" which could be interesting:
.inputMouseXAxisValue .inputMouseYAxisValue .mouseMovementX .mouseMovementY
Perhaps try out these.
Kirill Teltevskoy (Atrides) 11.09.2020 12:03
Thank. I'm going to try
Kirill Teltevskoy (Atrides) 11.09.2020 12:27
Everything is working! I got what I wanted! Thank!
